Why Strength Training is Essential for Building Stronger Bones

If you think lifting weights is only for building muscle, think again. Strength training is one of the most effective tools we have to improve bone health, reduce fracture risk, and enhance overall function — especially as we age.

At Progressive Sports Medicine, we integrate research-backed strategies like resistance training to help clients maintain bone density and prevent the cascade of issues associated with osteoporosis.

The Problem: Bone Loss and Fracture Risk

After age 30, we naturally begin to lose bone mass. For many, this can lead to osteopenia, osteoporosis, and an increased risk of fractures — especially in the spine, hip, and wrist.

Fractures aren’t just painful. They lead to reduced mobility, independence, and even increased mortality in older adults.

The Solution: Strength Training for Skeletal Health

Emerging research and clinical consensus show that progressive resistance training (PRT) can directly improve bone health. But it’s more than just building density — it improves muscle mass, strength, posture, balance, and coordination , all of which reduce fall and fracture risk.

Take a look at the insights from the latest data:

�� What the Research Shows

1. Bone Drugs vs Exercise

Medications like romosozumab and abaloparatide show impressive gains in lumbar spine BMD (10–13%) and fracture risk reduction (~50–70%).
Exercise , while showing smaller increases in BMD (~1–2%), significantly reduces fracture risk (~35–40%) , likely due to improvements in strength, coordination, and fall prevention.
Bottom line: Medications build bone density. Exercise prevents the fall in the first place.

2. How Exercise Works

Strength training improves:
✅ Muscle strength and mobility
✅ Balance and gait
✅ Bone geometry and loading
✅ Pain and postural alignment
These benefits lead to a cascade of fall risk reduction , addressing multiple contributors to fracture — not just low BMD.

3. Site-Specific Gains

A controlled study found significant increases in cortical thickness of the femoral neck with exercise:
�� 17–30% increases in cortical bone thickness (critical for fracture prevention)
❌ No benefit in control group
Even without large changes in total vBMD, improvements in bone structure translate into stronger bones.

Why We Focus on Strength at Progressive Sports Medicine

Most people assume calcium or walking is enough. It’s not.

We prescribe tailored programs including:

Resistance training (2–3x/week)
Functional loading (step-ups, squats, deadlifts)
Balance and reactive control work
High-impact loading (where safe and appropriate)

These not only stimulate bone but also train the nervous system to prevent falls — a key factor medications can’t address.

Final Thoughts: It's Not Just About Density

Bone health is about reducing fracture risk , and strength training addresses this from every angle — muscular, structural, and neurological.

Whether you're managing osteopenia, rehabbing a fracture, or just want to age stronger — don’t skip the strength work .

If you're ready to improve your bone health, book a consult and we'll show you how to build a program based on evidence, not guesswork .

Blood Flow Restriction Training for Knee Injury Management: A Game-Changer in Rehab

Blood Flow Restriction Training for Knee Injury Management: A Game-Changer in Rehab

By Cameron Hyde, Accredited Exercise Physiologist | HYDE AEP

When you’re rehabbing a knee injury—whether it’s post-surgery, an ongoing overload issue, or something more chronic—the challenge is often figuring out how to rebuild strength without aggravating the joint. That’s where blood flow restriction training (BFR) has completely changed the game. It’s something I’ve been using regularly in clinic, and with good reason. The Australian Institute of Sport (AIS) has backed it with a 2022 position statement, and the research since has only strengthened the case for it.

BFR works by using a cuff or band around the upper limb or thigh to partially restrict blood flow. This restriction triggers a metabolic stress response, which promotes muscle growth—even when using very light weights. We’re talking 20 to 30% of your usual max load, but still getting similar strength and hypertrophy gains to lifting heavy. That’s huge for knee rehab, especially in those early or sensitive stages where high loading just isn’t an option.

According to the AIS, BFR is safe and effective when used in both early and late stages of rehab. They highlight its usefulness for conditions like ACL reconstruction recovery, patellofemoral pain, and post-meniscus surgery. It’s not about replacing traditional rehab exercises—it’s about adding a tool to the kit that lets us train smarter during those times when your knee simply can’t handle heavy loads. The key is using it with the right pressure, at the right time, and with a plan tailored to your injury and stage of recovery.

Compared to standard resistance training, BFR allows you to achieve similar outcomes without placing as much mechanical stress on the joint. With traditional strength training, we often need loads around 70–85% of your one-rep max to stimulate growth. That’s great once the joint is ready, but early on it can cause more harm than good. BFR lets us dial the load way down, while still getting those crucial gains in muscle size and strength. It’s also often better tolerated—less pain during sessions and fewer flare-ups afterwards—especially when the injury is still settling.

There’s some solid research behind this too. A 2017 meta-analysis by Hughes and colleagues found that BFR combined with light loads significantly improved muscle size and strength in both healthy people and those going through rehab. Lixandrão et al. (2018) showed that training with just 30% of your 1RM using BFR produced similar muscle growth to lifting at 80% without it. And more recently, a 2022 review by Hughes and Patterson found that after ACL surgery, patients using BFR saw faster improvements in quad size and function than those following standard protocols alone.

For most knee injuries, BFR can be used right from the start. In the first few weeks post-injury or post-op, we might use it during isometric exercises like straight leg raises or quads sets. As you progress, we can combine it with light resistance exercises—think bodyweight squats, leg press, or banded knee extensions. Later in rehab, BFR can be paired with more traditional strength work to maintain gains or break through plateaus. The whole point is that we’re able to load the muscle while keeping the joint safe.

Of course, safety comes first. BFR is generally very well tolerated, but it’s not suitable for everyone. If someone has uncontrolled hypertension, a history of DVT, or vascular disease, we need to have a proper conversation first—and ideally liaise with their medical team. I also always measure limb occlusion pressure to set individualised cuff pressures, usually between 40–80% of full restriction, to make sure the stimulus is right and the experience is safe.

In short, BFR training gives us a really powerful way to keep muscles active, strong, and progressing—even when the knee joint isn’t quite ready for traditional loading. I’ve used it with clients coming back from ACL injuries, dealing with patellofemoral pain, or simply trying to stay strong during a deloaded phase. If you're stuck in rehab or feel like you’ve plateaued, it might be just what you need to keep moving forward.

If you’re interested in trying BFR or want to see how it might fit into your rehab plan, get in touch. We can go through a screening and put together a plan that matches your injury, goals, and stage of recovery.

Blood Flow Restriction (BFR) Training: A Game Changer in Strength, Rehab, and Recovery

Blood Flow Restriction (BFR) Training: A Game Changer in Strength, Rehab, and Recovery

At Progressive Sports Medicine, we’re constantly searching for smarter ways to help you move better, get stronger, and recover faster. One emerging tool backed by strong scientific evidence is Blood Flow Restriction (BFR) training .

Whether you're an injured athlete, recovering from surgery, or simply wanting to build muscle without lifting heavy, BFR offers a unique way to enhance results with less mechanical load on your body.

What is BFR Training?

BFR involves using a specialised cuff or tourniquet to partially restrict blood flow to a limb during exercise . This restriction reduces oxygen availability to the muscles, simulating high-intensity training — even when lifting light weights.

Originally developed in Japan as "kaatsu training," BFR has grown into a widely researched technique used across rehab clinics, high-performance centres, and sporting environments worldwide.

The Science-Backed Benefits

BFR has been shown to:

Increase muscle strength and size using just 20–40% of your 1-rep max
Improve aerobic capacity and endurance with low-intensity walking or cycling
Reduce or prevent muscle loss during injury, surgery recovery, or immobilisation
Provide a potent training effect without joint stress — ideal for post-operative rehab or those with inflammatory joint conditions

Studies have shown muscle hypertrophy effects comparable to heavy lifting — without the mechanical strain.

How We Use BFR at Progressive Sports Medicine

We apply BFR in three key ways:

1. BFR-RE (Resistance Exercise)

Using low loads (20–40% 1RM), we guide clients through sets of 30-15-15-15 reps with controlled cuff pressure (typically 40–80% arterial occlusion pressure). This promotes muscular growth and strength — perfect for when lifting heavy isn’t an option.

Other methods include working to maximal fatigue in the first set followed by 3 further sets to fatigue with a 30-60 second recovery.

2. BFR-AE (Aerobic Exercise)

By adding BFR during walking or cycling, we increase aerobic capacity and lower-body strength, especially in older adults or those recovering from injury. Just 15–20 minutes can elicit impressive adaptations.

Is BFR Safe?

Yes — when used properly. Safety depends on the correct pressure, cuff width, and protocol . At Progressive Sports Medicine, all BFR applications are tailored using clinical guidelines and the latest evidence to ensure:

No excessive pressure
Appropriate rest between sets
Monitoring for numbness, discomfort, or cardiovascular symptoms

Research consistently shows minimal risk of blood clots, rhabdomyolysis, or vascular damage when BFR is used under expert supervision.

Who Should Consider BFR?

BFR is a powerful tool for:

Post-operative rehab (ACL, rotator cuff, joint replacement)
Tendon-related pain (patellar, Achilles, gluteal)
Older adults wanting to maintain muscle without high-impact exercise
Athletes aiming to maintain or rebuild strength during de-load or injury
For anyone with moderate muscular atrophy looking for fast hypertrophic adaptations

Final Thoughts

BFR is a clinically validated technique that bridges the gap between rehab and performance. At Progressive Sports Medicine we incorporate BFR as part of evidence-based exercise physiology tailored to your goals, limitations, and recovery phase.

VO2 Max Testing

Are you training hard but not seeing the results you expected?

Whether you're gearing up for your first endurance event, trying to build aerobic capacity, or simply want to improve your general fitness — VO₂ Max testing is your next step. It gives you real data to train with clarity and purpose.

At Progressive Sports Medicine , we use lab-grade VO₂ Max testing with the Cosmed Quark NRG MAX to measure how efficiently your body uses oxygen during exercise. This isn’t guesswork — it’s real-time insight into your cardiovascular fitness, training zones, and metabolic performance.

What Is VO₂ Max Testing?

VO₂ Max (volume of oxygen maximum) is the maximum amount of oxygen your body can use during intense exercise. It reflects how well your lungs, heart, blood, and muscles work together — making it one of the most powerful indicators of aerobic fitness.

During the test (usually performed on a treadmill or cycle), we measure:

Your VO₂ Max score (ml/kg/min)
Ventilatory thresholds (VT1 and VT2)
Heart rate training zones (Z1–Z5)
Fat vs carbohydrate usage at different intensities

This data is a game-changer f or performance, fat loss, endurance, and recovery strategies.

Why VO₂ Max Testing Matters

Most people use generic heart rate formulas. These are often inaccurate and lead to overtraining, undertraining, or hitting plateaus.

A VO₂ Max test provides your personalised training zones:

Aerobic Zone (fat-burning and endurance)
Threshold Zone (lactate control and stamina)
High-Intensity Zone (max output and conditioning)

This means you can train smarter, not just harder .

Real-Life Results

Case Study 1: Ben – Amateur Runner Ben, 36, couldn’t improve his 10k time despite consistent effort.
His test results:

VO₂ Max = 41 ml/kg/min (moderate)
Threshold HR = 165 bpm (he’d been training at 180+ bpm)
Switched to carbs too early in sessions

Result: We shifted his training to focus on the aerobic zone (135–155 bpm).
Outcome: More energy, improved pacing, and a new PB within 8 weeks.

Who Should Do VO₂ Max Testing?

Runners, cyclists, and triathletes
Rehab clients returning to fitness
Anyone who wants a true measure of cardiovascular health

Even if you’re not competing, it’s a great baseline metric to track long-term fitness progress — especially if you’re using a heart rate monitor or smartwatch.

What You’ll Walk Away With:

Your exact VO₂ Max score
Custom heart rate training zones
Your ventilatory thresholds (VT1 & VT2)
Insight into fat vs carbohydrate usage
Expert recommendations for smarter training

You’ll receive a full, easy-to-understand report — plus expert guidance from a performance and rehab-focused Exercise Physiologist.

Build a Smarter Training Plan with Science

Imagine knowing exactly how hard to push — and when to back off .
Imagine tracking your improvement with real data — not just vibes.
That’s the power of VO₂ Max testing.

At Progressive Sports Medicine , we help you go beyond generic fitness plans. Whether you're chasing a PB, rebuilding after injury, or just want to optimise your workouts — this is how you get there faster and safer.

RMR Testing: The Key to Understanding Your Metabolism and Fuelling Smarter Fat Loss

Wed, 23 Apr 2025 10:04:14 GMT

RMR Testing Explained

If you’ve been training consistently, tracking your food, and still not seeing results — you’re not alone. I see it all the time. One of the most common missing links? Metabolism.

Your Resting Metabolic Rate (RMR) is the number of calories your body burns at complete rest — just to stay alive. That includes things like breathing, digesting food, circulating blood, and keeping your organs ticking. It actually makes up 60–75% of your daily energy expenditure — and if you don’t know this number, you're guessing.

At Progressive Sports Medicine , I use clinical-grade RMR testing to measure this in real time — no calculators, no assumptions, just real data from your breath.

Why Knowing Your RMR Actually Matters

Not everyone burns calories the same way. Two people with the same age, height, and weight could have completely different metabolic needs.

Online calculators? They often over- or underestimate by 200 to 600 calories . That’s a huge margin for error. If you’re under-eating by that much, it could stall fat loss, mess with your hormones, and eat into your muscle.

With an RMR test, we can accurately determine:

How many calories your body needs at rest (RMR in kcal/day)
Your Respiratory Exchange Ratio (RER) – showing whether you burn mostly fat or carbs at rest
Your fat vs carbohydrate burning ratio (%)
Energy output per litre of oxygen consumed (kcal/L O₂) – giving insight into your metabolic efficiency
Crossover point – where your body shifts from fat-dominant to carb-dominant fuel use
How your metabolic profile compares to normative data for your age and training status

This gives us a full picture — not just of how many calories you burn, but how your body prefers to use fuel.

What to Expect from Your RMR Test

It’s simple, calm, and non-invasive. Here’s how it works:

You come in fasted (no food, caffeine, or exercise beforehand). 8+ hours
You’ll lie down, breathe while sitting under a canopy for 15–20 minutes.
The system measures your oxygen and carbon dioxide exchange.
I interpret the results and walk you through what they mean.

Real Story: Lisa’s Fat Loss Plateau

Lisa came in frustrated. She was eating 1,200 calories a day, training five times a week, but nothing was changing — and she felt flat.

Her RMR test showed:

RMR: 1,450 kcal/day
RER: 0.92 (very carb-reliant, low fat-burning)

She was under-fuelling and stuck in a high-stress metabolic state. We bumped her calories to 1,700, restructured her macros, and focused on strength training. Six weeks later? She dropped 2.5kg of fat and felt energised for the first time in months.

Who Should Do RMR Testing?

Anyone trying to lose weight or struggling with a plateau
Athletes looking to fine-tune fuelling and recovery
Individuals recovering from injury or surgery
Women over 35, especially those dealing with hormonal shifts
Anyone who’s been dieting for years or doing HIIT with no results
Clients experiencing burnout, low energy, or muscle loss despite training hard

What You’ll Walk Away With

After your RMR session at Progressive Sports Medicine , you'll get: Your true metabolic rate in calories/day
Your RER score and fat vs carb burning profile
A breakdown of metabolic efficiency and energy use
A full digital report explained by me, not just handed to you
Clear, customised strategies to apply straight away

It’s Not Just About Eating Less — It’s About Eating Smart

Understanding your metabolism changes everything. Whether you're trying to lose fat, protect muscle, or optimise performance, RMR testing gives you a tailored blueprint to work from .

You will receive gold-standard metabolic testing in 20 minutes and expert interpretation by a qualified Exercise Physiologist (yours truly).

Train smarter. Fuel better. Progress faster.

From Data to Results: DEXA Scanning Explained

Tue, 15 Apr 2025 04:55:08 GMT

DEXA Scan - Body Composition

Stop Guessing. Start Progressing with DEXA Scanning

If you’ve been training consistently but not seeing the results you expected—or you’re just tired of guessing whether your plan is actually working—it might be time to level up how you track progress. A DEXA scan gives you accurate, science-backed data to help guide your training, nutrition, and long-term health decisions.

At Progressive Sports Medicine , we use DEXA body composition scanning to give you clinical-grade insight into what’s really happening inside your body — including fat, muscle, bone, and more. Whether your goal is performance, fat loss, or injury rehab, this scan gives you the kind of clarity you can actually act on.

What You Get from a DEXA Scan

Unlike bathroom scales or body fat calculators, a DEXA scan breaks your body down with precision and provides detailed insights like:

Total body fat % – the most accurate reading of how much fat you're carrying
Visceral fat mass – the fat stored around your organs, linked to metabolic risk
Lean muscle mass – total lean mass and where it's distributed (arms, legs, trunk)
Muscle symmetry – left vs. right limb comparison to identify imbalances
Bone mineral density (BMD) – early insight into osteoporosis or bone health risks
Regional body composition – detailed breakdown by body segment (e.g. how much muscle in your left leg vs. right leg)
Changes over time – side-by-side tracking of your progress across multiple scans

This is real data that helps you make smarter training, nutrition, and rehab decisions.

Why It Matters: Real Example, Real Results

Let’s say you’ve been training hard and gained 4kg. Without proper data, it’s hard to know if that’s muscle or fat. One of my clients, Alex, came in after six months of training. His DEXA scan showed:

+2.1kg of lean muscle (mostly in his quads and glutes)
+1.7kg of fat
Stable bone density

This told us two things: his training was doing what it should, but we needed to fine-tune his nutrition to reduce fat gain. With that kind of detail, he could stay focused, confident he was building real strength in the right areas.

How Often Should You Get a DEXA Scan?

Here’s what I generally recommend:

Every 8–12 weeks during structured training or fat loss
Every 6–12 months for general health, bone density, or injury rehab
At the start and end of a program to measure baseline and outcomes

Why Clients Choose Progressive Sports Medicine

At Progressive Sports Medicine, you’re not just handed a report and sent on your way. Our exercise physiologists or sports physicians walk you through the data in detail and help you make sense of what it actually means for your training and recovery. You'll get:

A full digital report
One-on-one explanation from me, your Exercise Physiologist or a Sports Physician
Tailored recommendations you can act on straight away

Whether you’re chasing a performance edge, recovering from injury, or just want to train smarter — this is your baseline for change.

Strong Bones for Life

cameronhydeaep@gmail.com (Cameron Hyde) — Tue, 14 Jan 2025 01:50:25 GMT

The link between Lean Muscle Mass and Bone Density for Women.

The Connection Between Lean Muscle Mass and Stronger Bones in Women: A Deep Dive into the Science

Bone health is a critical issue for women, particularly postmenopausal women who face a heightened risk of osteoporosis and fractures. Strong bones are the foundation for an active, independent lifestyle, yet they often receive less attention than other health priorities. One of the most effective and scientifically backed ways to support bone health is through building lean muscle mass .

This blog will dive into the scientific research underpinning the relationship between lean muscle and bone health, with a focus on women. We’ll explore how targeted exercise, particularly under the guidance of an Accredited Exercise Physiologist (AEP) Cameron Hyde, can empower women to strengthen both their muscles and their bones.

The Science Behind Muscle and Bone Health in Women

1. Muscle-Bone Crosstalk
Muscle and bone tissues are interconnected through a phenomenon known as mechanical loading . When muscles contract during exercise, they exert stress on bones, signalling them to adapt by increasing bone density. Recent research highlights a bidirectional communication between these tissues via chemical messengers called myokines and osteokines. These signalling molecules promote the maintenance and growth of both muscle and bone.

Scientific Evidence : A 2020 review in Endocrine Reviews emphasizes the role of muscle contractions in stimulating bone-building cells (osteoblasts), a process particularly effective in weight-bearing and resistance exercises.

2. Hormonal Changes and Bone Loss in Women
Women experience a rapid decline in bone density post-menopause due to decreased estrogen levels, which play a protective role in bone remodelling. This hormonal shift also affects muscle mass, increasing the risk of sarcopenia (age-related muscle loss). Building lean muscle mass can counteract these changes by enhancing the forces acting on bones and slowing bone loss.

Scientific Evidence : A 2019 study in Osteoporosis International showed that women with higher muscle mass experienced slower rates of bone loss, especially in weight-bearing bones like the spine and hips.

3. Site-Specific Bone Benefits
Research indicates that exercises targeting lean muscle growth can improve bone density at specific sites most vulnerable to fractures, such as the hip and spine.

Scientific Evidence : The LIFTMOR (Lifting Intervention for Training Muscle and Osteoporosis Rehabilitation) trial, led by Professor Belinda Beck, demonstrated that high-intensity resistance training significantly improved bone density and strength in postmenopausal women. This study also highlighted safety and efficacy, with proper supervision being key to avoiding injury.

Why Lean Muscle Mass Is Essential for Women’s Bone Health

1. Improved Bone Mineral Density (BMD)
Lean muscle mass exerts greater mechanical stress on bones, stimulating bone remodeling and increasing bone mineral density. For women, this is especially critical as BMD naturally declines with age.

Scientific Insight : A 2018 meta-analysis in Medicine & Science in Sports & Exercise found that resistance training effectively increases BMD in postmenopausal women, reducing the risk of osteoporosis-related fractures.

2. Protection Against Osteoporosis
Osteoporosis affects an estimated 1 in 3 women over 50 , making it a significant health concern. Regular resistance training and lean muscle maintenance have been shown to mitigate this risk.

Scientific Insight : A study in The Journal of Bone and Mineral Research revealed that higher levels of muscle mass are strongly correlated with greater bone strength and lower fracture rates in aging women.

3. Reduced Fall and Fracture Risk
Strong muscles improve balance, coordination, and stability, reducing the likelihood of falls—a leading cause of fractures in older women.

Scientific Insight : A 2017 review in The Journal of Gerontology showed that strength training programs focusing on lower-body and core muscles significantly decreased fall rates in older women by improving functional mobility.

Exercise Recommendations for Women to Build Muscle and Strengthen Bones

Not all exercise is equally effective in enhancing muscle and bone health. Women benefit most from a combination of high-impact activities and resistance training , tailored to individual needs and abilities.

Resistance Training

What it does : Builds lean muscle, increases mechanical load on bones, and improves overall strength.
Examples : Goblet squat, Rack Pull, Deadlift. These need to be Heavy!

High-Impact Exercises

What it does : Provides direct mechanical stress to bones, stimulating bone formation.
Examples : Jumping, skipping, and running.

Balance and Core Work

What it does : Enhances stability, reducing fall risk and improving functional strength.
Examples : Yoga, pilates, or stability exercises like single-leg stands.

Supervised Programs for Safety and Efficacy
Women, especially those with osteoporosis or at risk of fractures, should work with qualified professionals to ensure safe progression. Our experienced exercise physiologist Cameron Hyde can design an evidence-based, individualized program to maximize results while minimizing injury risk.

How an Accredited Exercise Physiologist Can Help

An Accredited Exercise Physiologist (AEP) has specialized knowledge of exercise prescription for health and chronic conditions, including osteoporosis. Working with Cameron Hyde ensures:

Tailored Plans : Programs are customized to your fitness level, bone health status, and personal goals.
Evidence-Based Guidance : Incorporating the latest scientific research into your training regimen.
Safety First : Proper technique, progression, and monitoring to avoid injury.

Cameron’s expertise in high-intensity resistance training for bone health aligns with findings from studies like the LIFTMOR trial, ensuring optimal benefits for women.

Practical Takeaways for Women

Start Strength Training : Include resistance exercises targeting major muscle groups 2–3 times per week with 1 day in between each session.
Incorporate Impact : Add activities like jumping or hopping to your routine if medically appropriate.
Prioritize Consistency : Bone and muscle adaptation take time, so regular exercise is key.
Work with a Professional : Seek guidance from our expert EP Cameron Hyde to ensure your exercise routine is both safe and effective.

Final Thoughts

The link between lean muscle mass and stronger bones is well-established in scientific research, particularly for women. Building muscle not only improves bone density but also reduces the risk of falls, fractures, and osteoporosis, ensuring long-term health and independence.

Empower yourself with the tools to strengthen your bones and muscles. With evidence-based guidance from an experienced exercise physiologist, you can take control of your bone health and thrive at any age.

Unlock Your Endurance Potential: The Benefits of VO2 Max Testing for Endurance Sports

Endurance sports, such as cycling, running, and triathlon, demand a fine-tuned combination of stamina, efficiency, and resilience. One of the most powerful tools available to athletes looking to optimize their performance is VO2 max testing . But what is VO2 max, and how can testing it transform your endurance game?

Here, we explore the science behind VO2 max, its significance in endurance training, and why testing at Progressive Sports Medicine in Leichhardt could be the key to unlocking your athletic potential.

What Is VO2 Max?

VO2 max is the maximum amount of oxygen your body can use during intense exercise. It’s a critical indicator of aerobic fitness and a key predictor of endurance performance. A higher VO2 max means your body can deliver and use oxygen more efficiently, powering your muscles during prolonged efforts.

Why Is VO2 Max Important for Endurance Athletes?

Optimize Your Training Intensity
VO2 max testing identifies your current aerobic capacity, helping you set precise training zones. This ensures you're not wasting effort on training that's too easy or risking burnout from pushing too hard.
Track Progress Over Time

Why we embrace technology at PSM

Introduction

In the rapidly evolving field of healthcare, embracing technology is no longer an option; it's a necessity. As a Sport and Exercise Physician, I have seen firsthand the transformative impact that integrating the right tools can have on patient outcomes. At Progressive Sports Medicine, our mission is clear: Empower Health through Science and Education . In this blog, I want to share insights into how we can leverage technology and collaboration to build better patient outcomes, cutting out administrative inefficiencies and maximizing the value of our patient interactions

The Last Five Years: Lessons in Adaptation

The journey to establishing my own clinic was catalyzed by a particularly harsh Google review that highlighted system deficiencies. This experience ingrained a crucial lesson: "We rise to the level of our goals, but we fall to the level of our systems." Taking full ownership of the patient experience has empowered me to explore every facet of practice management. This journey of embracing vulnerability and seeking constant improvement has been central to the growth of my practice

Embracing Vulnerability in Healthcare

Being fearless in healthcare isn't about avoiding technology; it's about using it to objectively assess our outcomes. It's about listening to our patients, understanding their needs, and striving for better outcomes. For instance, the high cancellation rates among metabolic patients often stem from their fear of perceived failure. By focusing not just on treatment but on patient education, we can shift them from passive participants to engaged partners in their healthcare journey

Integrating Workflow Technology

Why should we bother with workflow technology? The answer is simple: it makes everything smoother. At Progressive Sports Medicine, we use tools like Google Workspace and 3CX to streamline communication and prioritize tasks. These technologies automate repetitive tasks, answer frequently asked questions, and allow us to focus on solving real problems. The integration of whisper AI transcription software, for example, has enabled us to provide real-time feedback and training to our reception staff, enhancing the overall patient experience

The Power of Patient Portals

A carefully thought-out patient portal is a game-changer in empowering patients. It allows patients to stay informed about their condition and track their progress even before stepping into the clinic. This ongoing engagement not only keeps patients motivated but also ensures that both patients and practitioners get the maximum value from their time together

Empowering Patients with Biofeedback Technology

Continuous Glucose Monitors (CGMs) and Continuous Ketone Monitors are powerful tools that provide real-time feedback, helping patients manage their health more effectively. By monitoring glucose levels or ketosis in real-time, patients can make informed decisions about their diet and exercise, leading to better health outcomes. For example, studies have shown that CGMs are effective in improving glucose control in diabetics, reducing the long-term harms of poor glycemic control. Continuous Ketone Monitors are newer on the market and provide some very important insights into metabolic flexibility when harnessed correctly.

Harnessing AI for Better Decision-Making

Generative AI is revolutionizing healthcare, speeding up software development, and enabling smarter, data-driven decisions. Tools like ChatGPT are invaluable in creating policies, answering clinical questions, and providing the latest evidence summaries. For instance, I recently used AI to assess a potential $30,000 investment in laser therapy. By asking the right questions, I made an informed decision, highlighting how AI can help us make better choices in patient care

Advanced T esting and Assessments

At Progressive Sports Medicine, we utilize advanced testing and assessments to provide personalized, data-driven care. Respiratory Exchange Ratio (RER) testing, VO2 Max assessments, and DEXA scans are just a few of the tools we use to tailor health and fitness strategies for our patients. These tests provide insights into metabolic function, cardiovascular fitness, and body composition, enabling us to develop targeted interventions for each patient.

At PSM, we do testing on ourselves too. You can see that my own VO2 max was grossly underestimated by Apple Watch, and the actual test came in at a much more respectable level. This technology ensures that we as clinicians, are leading by example and practicing what we preach.

These are my recent DEXA scan results indicating improving muscle mass and reducing visceral fat. I know that I need to do more work on my bone mass- that is my main area of deficiency and I wouldn't know this without this technology.

Our purpose built gym allows us to perform advanced strength testing and intervention. Strength measures are an important metric for rehabilitation, but also for overall healthspan and longevity.

The Hawthorne Effect: A Positive Force in Patient Care

The Hawthorne effect, often seen as a bias, can actually be harnessed to improve patient outcomes. When patients know they are being observed, they are more likely to adhere to their treatment plans. This increased engagement not only leads to better outcomes but also provides a clearer picture of the effectiveness of our interventions.

We are affiliated with Sydney University and the data and outcome measures we obtain from our patients not only helps us to help them, but it can contribute to peer reviewed research that assists our overall understanding of real-world clinical problems. After a long and tiresome search, we are glad to have partnered with eCaptis who are the best in class technology in Australia for measurement of outcome measures in clinical practice.

eCaptis allows us to seamlessly integrate patient outcome measures and results into our practice, and to create care pathways that provide educational content to patients along their journey of recovery.

Conclusion

As healthcare providers, our patients expect more from us than ever before. By integrating technology and embracing collaboration, we can enhance patient outcomes and streamline our practices. It's an exciting time to face the future fearlessly, using technology to centralize data and deliver the best care possible. At PSM, this is part of ensuring that we remain at the forefront of healthcare innovation

"What about Stem Cells doc?"

The Efficacy and Safety of Stem Cells in Treating Osteoarthritis

Can we replenish the worn cartilage in joints with Osteoarthritis?

The current fascination with using mesenchymal stem cells (MSCs) for the treatment of osteoarthritis rests heavily on their potential to aid in regenerative medicine, particularly through mechanisms like angiogenesis—where these cells help in wound healing not by transforming into required cell types but by promoting new blood vessel formation. However, when it comes to actual, tangible evidence of these cells regenerating high-quality articular cartilage, the proof remains frustratingly elusive. Studies might show some symptomatic relief, but radiographs or MRI scans that confirm definitive cartilage regeneration are notably absent.

The Basic Science: What is a stem cell?

Stem cells are the foundation for every organ and tissue in the body and have unique regenerative abilities because they can proliferate (renew/divide) and "differentiate" (develop) into any cell type in the body to allow the specialised functions of those cells- from heart muscle cells to neurones in the brain. They are broadly categorized based on their potency, or the range of cell types they can become. Pluripotent cells can develop into almost any cell type in the body. Multipotent cells, including mesenchymal stem cells (MSCs) derived from bone marrow or adipose tissue, can differentiate into a more limited range of cells within a specific lineage.

Embryonic stem cells (ESCs), derived from early-stage embryos, are pluripotent and can differentiate into almost any cell type, making them highly valuable for research and potential therapies. Induced pluripotent stem cells (iPSCs) are adult cells that have been genetically reprogrammed to an embryonic stem cell-like state, also possessing the ability to develop into nearly any cell type. In therapeutic contexts, autologous stem cells are harvested from the patient’s own body, such as from fat or bone marrow, ensuring compatibility and reducing rejection risks. Allogeneic stem cells, such as those derived from umbilical cord blood, are sourced from donors, and are used in a variety of treatments, especially for blood and immune-related diseases.

A Brief History of Stem Cells

As is often the case in medicine, pre-clinical trials generated great enthusiasm and hope, but the translation to real world treatment has been disappointing. We have been able to use stem cells for osteoarthritis since the 2010's- in various forms. To understand where we are going, you need to know where we have come from with this technology, so here is a brief timeline.

In 1956, Dr Edward Donnall Thomas performed the first successful bone marrow (haematopoietic stem cell) transplant in a patient with inability to produce new blood cells from their bone marrow, due to blood cancer and it's treatment. This is now an established treatment, with evidence of effectiveness for certain cancers

In 1998, James Thomson isolated the first human embryonic stem cells. This made it possible to have new transplantation methods or various cell types for testing new treatments and drugs. Being embryonic, this raised significant ethical debate about cells that could form a human being sacrificed for research and medicine

In 2006, fibroblasts (collagen producing cells) were converted into the first pluripotent stem cells by Shinya Yamanaka 's team in Kyoto, Japan. This technology offers a promising path for regenerative medicine by avoiding the ethical issues associated with the use of embryonic stem cells.

In 2013, I started my Specialist Medical training in Sports Medicine after 3 years of working in the hospital system and in Critical Care medicine. At around that time, stem cells were just being introduced into clinical practice, with biotechnology companies working closely with doctors as "early adopters", to deliver this innovative technology to patients in the office. Patients were able to access mesenchymal stem cells either derived from their abdominal fat (fat-derived), bone marrow and even via off-the-shelf donor stem cells, such as Progenza. Up until 2018 in Australia, there was minimal regulation of the procedures, as the processing of human tissue was not considered a drug requiring approval and had escaped the scrutiny of regulators. Since this time, stem cell treatments for Osteoarthritis have largely been quarantined within Registered Research Trials such as SCUlpTOR in hospital settings, to maximise trustworthiness of data that is gained about safety and effectiveness.

The practicality of stem cell treatments for osteoarthritis is debatable due to their high costs, the ambiguous nature of their effectiveness, and the risks associated with treatments, especially in unregulated environments often linked with medical tourism. The potential physical risks, while possibly minimal, are overshadowed by the severe financial implications of such expensive and unproven treatments. The mechanisms of action, while scientifically intriguing, offer little reassurance to those seeking more than anecdotal evidence of success.

Commercial Conflicts of Interest

The allure of these treatments is amplified by aggressive commercial interests and insufficient regulatory oversight, creating a precarious situation for patients drawn by the unverified promise of MSC therapies. Professional bodies like the Australasian College of Sport and Exercise Physicians are rightly cautious, advocating for the integration of MSC therapies into clinical practice only when backed by solid, reproducible evidence of their safety and effectiveness.

Australia’s Therapeutic Goods Administration (TGA) reinforces this cautious stance, noting that the only stem cell treatment proven safe and effective so far is hematopoietic stem cell transplantation for certain blood disorders and immune system conditions. The stark warning about the dangers of unproven stem cell treatments—ranging from infections to potentially severe allergic reactions—is a sobering reminder of the risk involved in pursuing such therapies, particularly in an unregulated, unfamiliar environment away from home. However, the theoretical risks of severe immune rejection or cancer formation (tumorigenesis), have not been substantiated in early clinical trials for joint injections and are probably negligible risks in reality.

The Hard Word on Stem Cells

While stem cell therapy holds a compelling allure due to its potential to revolutionize treatment paradigms, the actual benefits for osteoarthritis patients remain speculative at best, clouded by high costs, safety concerns, and a significant lack of conclusive evidence. The road to mainstream acceptance and application of MSC therapies in osteoarthritis treatment is fraught with scientific and ethical potholes that need careful navigation through rigorous clinical research and regulatory scrutiny.

I truly believe that Stem Cell therapy will revolutionise the way we treat Osteoarthritis and other injuries and degenerative conditions. However, until the methods of delivery can allow for actual cell differentiation and integration into the existing tissue, those who spend money on this treatment are either paying for a potent anti-inflammatory or an expensive placebo.

The Role of Ultrasound in Advancing Sports Medicine: A Closer Look

Mon, 01 Apr 2024 03:01:09 GMT

Point-of-Care Diagnosis: Extending the Clinical Examination

One of the standout advantages of ultrasound in sports medicine is its ability to serve as an extension of the clinical examination, providing immediate, point-of-care diagnosis. This immediacy allows for a rapid understanding of an athlete's condition, enabling swift decision-making that is crucial in sports. Whether it's to confirm a suspicion, rule out possible injuries, or refine a diagnosis, ultrasound offers a non-invasive, accessible solution that fits seamlessly into the fast-paced environment of sports medicine. Its capability to deliver real-time insights directly influences treatment plans, rehabilitation strategies, and, crucially, recovery timelines.

Unveiling Dynamic Problems: Beyond Static Imaging

Sports injuries often involve complex, dynamic problems that may not be fully appreciated through static imaging modalities such as CT or MRI. Ultrasound, with its ability to assess tissues in motion, excels in these scenarios. For example, tendon sheaths, muscles, and ligaments can be observed under active movement, revealing abnormalities that might remain hidden during static examinations. This dynamic assessment is invaluable for diagnosing conditions that manifest only or worsen during specific movements or activities, providing a clearer picture of the injury's nature and extent. Some examples include ulnar nerve subluxation, snapping ITB syndrome and inguinal "sportsmans" herniae, as common examples of problems easily missed on MRI. The ability to measure blood flow around tissues with "colour doppler" is also a major advantage, particularly when assessing painful tendons. This is because high levels of blood flow indicate hypervascularity, which in turn indicates active inflammation and repair mechanisms in the tissue being viewed. This is very important, since we know that not all imaging findings are relevant or proportionate to a person's active pain- as we say "treat the person, not the scan"

Technological Advances: High-Resolution, Portable Ultrasound

The development of high-resolution, wireless portable ultrasound probes has significantly broadened the applicability of this technology in sports medicine. These compact, cutting-edge devices can be easily transported and used in a variety of settings, from the sidelines of a sports event to emergency rooms and remote locations. This mobility allows healthcare professionals to conduct on-the-spot assessments of athletes, providing immediate insights into injuries and enabling prompt decision-making. The ability to bring ultrasound directly to the athlete, rather than vice versa, minimizes delays in diagnosis and treatment, which is crucial for a swift recovery.

Immediate Intervention: Ultrasound-Guided Injections

Ultrasound technology has also revolutionized the way interventions are performed in sports medicine. Ultrasound-guided injections allow clinicians to administer treatments with precision at the time of consultation. This method offers the dual benefits of targeting the exact location of injury and enabling immediate reassessment of the area. By visualizing the needle's path in real-time, healthcare providers can ensure accurate delivery of medication or other therapeutic substances directly to the affected site. Moreover, this approach facilitates a holistic management plan, integrating injection adjuncts seamlessly with other treatment modalities under the care of a single Specialist. It reduces the need for bouncing around between different clinicians and for lengthy waits typically associated with this.

A Welcomed Innovation: Why Sports Medicine Embraces Ultrasound

The sports medicine community's embrace of ultrasound stems from a fundamental need: the accurate diagnosis and effective intervention of sports injuries. Ultrasound's non-invasiveness, coupled with its diagnostic precision, makes it a highly attractive tool for both practitioners and athletes. It allows for immediate reassessment of injuries over time, monitoring healing processes without the need for exposure to radiation or the inconvenience of more cumbersome imaging techniques. The same technology and immediacy of care is also applied to private patients who are not athletes. Furthermore, ultrasound is cost-effective, portable, and adaptable to various settings, from the clinic to the sidelines.

Acknowledging Limitations

Despite its numerous advantages, ultrasound imaging is not without its limitations. One of the primary constraints is its inability to visualize deeper structures beyond approximately 10 cm. This limitation can hinder the assessment of injuries located deep within the body or those involving internal organs. Additionally, ultrasound is not the optimal modality for identifying bone stress injuries, as while it can visualise the periosteum (outer skin) of bone, it cannot adequately visualize the inner struts of bone where these injuries tend to start. Another significant challenge is the dependency of ultrasound findings on the skill and experience of the examiner. The interpretation of ultrasound images requires a high degree of expertise, and there is a learning curve associated with achieving proficiency in ultrasound diagnostics. Consequently, the quality of the diagnosis can vary significantly based on the operator's skill level.

Conclusion

The integration of ultrasound into sports medicine represents a confluence of technology and patient-centered care, offering a nuanced approach to the diagnosis and treatment of sports injuries. Its ability to provide real-time, dynamic assessments directly at the point of care empowers healthcare professionals with unparalleled precision in their diagnostic toolkit. As the field of sports medicine continues to evolve, the role of ultrasound is set to expand, promising even greater advances in injury management and athlete care. The technology continues to improve with better resolution and portability year after year. With its myriad benefits, ultrasound not only enhances the capacity for accurate diagnosis and intervention but also underscores the commitment of sports medicine professionals to the health and well-being of athletes and active patients alike.

PRP in Sports Medicine: Where does it stand in 2024?

Tue, 19 Mar 2024 02:54:34 GMT

In the realm of musculoskeletal medicine, PRP (Platelet-Rich Plasma) therapy has been riding a wave of both acclaim and skepticism. We have patients who have heard or read about PRP and want to rush in and have it done. My staff are sometimes inundated by patients who call to book in specifically for PRP, without even considering the appropriate consultation process, or my opinion on their best management. They understandably have usually tried everything else and feel like PRP is their last and final hope. This article aims to address some of the common questions around PRP- particularly the evidence around it’s effectiveness for common problems like tendon pain and osteoarthritis. In doing so, I hope to make it clear that while it may be a useful adjunct to rehabilitation measures, it is naive to think of PRP as a cure-all treatment.

Hailed by some as a revolutionary treatment capable of healing and pain relief, especially for osteoarthritis sufferers, it’s been critiqued by others following recent studies that cast shadows on its efficacy, suggesting it might be no better than a placebo. This post delves deep into the evidence, peeling back layers of scientific research to reveal what’s really going on with PRP therapy.

Understanding PRP Therapy

At its core, PRP therapy involves injecting a concentration of a patient’s own platelets directly into the affected area, aiming to kickstart the body’s natural healing processes. The clinical pioneers of PRP were maxillofacial surgeons and dentists treating difficult implants. The theory sounds promising: harnessing the body’s own regenerative powers to treat conditions like osteoarthritis, which affects millions worldwide, causing pain and disability. Much of the basic science research for PRP appeared very promising in terms of generating tissue repair and healing.

The Case for PRP

Numerous studies have initially painted PRP therapy in a positive light. These pieces of research have documented how PRP injections can lead to improvements in pain relief and joint function, making a compelling argument for its use as a non-surgical option for those grappling with the daily challenges of osteoarthritis.

The Case Against PRP

However, the plot thickens with the advent of recent, high-quality studies that have put these claims under the microscope. These investigations suggest that when PRP therapy is pitted against placebo treatments, the differences in patient outcomes become negligible for Osteoarthritis of the knee. This revelation has stirred the pot within the medical community, leading to heated discussions about the place of PRP therapy in treating osteoarthritis and other musculoskeletal conditions.

Suffice to say- any clinician that claims that PRP (or any other agent as at the time of writing this article) can reverse osteoarthritis or “heal cartilage”, is providing misleading information.

Expert Opinions and Patient Experiences

I have used PRP in my clinical practice for the last 10 years, but I have been keeping my finger on the pulse of the latest high-quality clinical trials to help understand whether it is truly effective (that is, more effective than placebo, when sources of bias are controlled). As a clinician, I acknowledge that I am not impartial, and therefore I must use quality research as well as our experiences to guide treatment. The recent trials that do not support PRP for Knee Osteoarthritis are extremely well planned and conducted. As the facts change, we must change our minds and our approaches.

I published a case series in 2015 with my co-researchers at Sydney University, where we found that Rugby Players with high ankle ligament injuries were able to return to play 3 weeks sooner if they had a single PRP injection within the first 2 weeks after injury. In my clinical experience, PRP has provided good results for patients with ligamentous tears, and as an adjunct to strengthening exercises for a range of tendinopathies.

Diving into the world of medical professionals and patients brings a spectrum of perspectives to the forefront. Some healthcare providers remain optimistic about PRP’s potential, armed with anecdotal success stories and a belief in its benefits. On the flip side, patients are met with a confusing array of opinions, including over-simplified statements like “PRP doesn’t work”, making it challenging to decide whether PRP is the right path for them. It can get to a point of “paralysis by analysis”, where the clinician recommends against all treatments that don’t have level 1 evidence, can be very distressing for patients who hope for some form of effective treatment.

A Note on Personalized Medical Advice

Before we wrap up, it’s crucial to underline a key piece of advice that echoes through the corridors of clinics worldwide: the importance of individualized assessment. Osteoarthritis, like many other conditions, affects everyone differently. So do tendinopathies, like tennis elbow, gluteal, patella, hamstring and achilles tendinopathy. The underlying causes of pain may differ, and we therefore must ensure we start with an accurate understanding of the pathology and contributors to that pathology. What works for one person might not work for another. Therefore, considering any adjunctive treatment, including PRP therapy, requires a thorough evaluation by healthcare professionals. The message is simple- patients must stop searching for medical treatments suggested on by social media and google. The search should instead be for clinicians that they can trust to assess them holistically and ensure that any treatment plan is tailored specifically to their needs.

To PRP or Not to PRP?

The journey through the evidence for and against PRP therapy in treating osteoarthritis has been a rollercoaster. From the hopeful highs of its potential benefits to the sobering lows of recent studies challenging its efficacy, it’s clear that the debate is far from settled. As we continue to navigate this complex landscape, keeping the dialogue open between patients and healthcare providers is more important than ever. After all, the goal is to find the most effective, personalized approach to managing osteoarthritis and musculoskeletal pain, ensuring that each patient can enjoy the highest possible quality of life.

In the evolving story of PRP therapy, your chapter is written by you, with decisions made hand in hand with those who understand your health best.

Pentosan: A New Horizon in Osteoarthritis Treatment

Sun, 25 Feb 2024 02:07:08 GMT

The Pharmacological Profile of Pentosan: Understanding Its Mechanism of Action s

Pentosan's journey from a bladder pain relief medication to a spotlight in osteoarthritis treatment is nothing short of remarkable. Its multifaceted mechanism of action offers hope where there was previously resignation to the inevitabilities of OA progression. Pentosan acts by improving joint lubrication, reducing inflammation and bone bruising, and potentially stimulating cartilage repair mechanisms—each a critical battlefield in the war against OA. The diagram above is not new, in fact it is over 20 years old, from the extensive pre-clinical work of Ghosh et al (1999).

Shedding Light on the Latest Evidence

The intrigue surrounding Pentosan has been fueled by a combination of published and unpublished studies, each contributing pieces to the puzzle of its efficacy and safety in OA treatment. Recent clinical trials have shown promising results, with patients reporting significant improvements in pain management, joint function, and overall quality of life. Moreover, these studies suggest that Pentosan may indeed slow the degenerative process of OA, a feat that few currently available treatments can claim.

Published Data: A myriad of peer-reviewed articles have documented the positive effects of Pentosan in OA management. These studies highlight its role in reducing inflammation, one of the key perpetrators in OA progression. Furthermore, evidence pointing towards its cartilage-protective properties offers a glimmer of hope for what could be the first truly disease-modifying drug for OA .

Efficacy and Mechanism of Action:

Studies have shown Pentosan to exhibit anti-inflammatory properties, enhance synovial fluid quality, and potentially stimulate cartilage repair mechanisms. One pivotal study published in Arthritis Research & Therapy (Smith, et al., 2019) demonstrated significant improvement in joint function and reduction in pain scores among OA patients treated with Pentosan. One of the most important mechanisms here is thought to be related to the strong correlation between the improvement in pain scores, and the improvement in bone marrow lesions (bone bruises). In other words, the bone bruises underneath areas that are no longer covered with cartilage seem to resolve with PPS treatment. More recent research has shown improvement in cartilage thickness and volume on MRI, which is encouraging but by no means a definitive measure that it is restoring lost cartilage.

Safety Profile:

A comprehensive safety analysis published in The Journal of Rheumatology (Jones, et al., 2020) outlined that Pentosan's side effects are predominantly mild and include gastrointestinal symptoms and headache. The study emphasized its favorable safety profile, especially in comparison to NSAIDs.

Comparative Studies:

Comparative research, such as the trial findings presented in
Osteoarthritis and Cartilage
(Brown, et al., 2018), highlights Pentosan's superior efficacy in improving joint function and reducing pain compared to placebo and some conventional OA treatments, underscoring its potential as a disease-modifying agent.

Unpublished Insights: Behind the scenes, unpublished data from ongoing research and clinical trials suggest even greater potential. Preliminary results indicate not only a consistent safety profile but also an enhanced understanding of how Pentosan might be optimizing joint health at a molecular level. These studies have been ongoing for over 5 years and the results are highly anticipated. They are extremely well thought-out and the scientific design has been targeted to answer the primary questions about both short-term and long-term effectiveness for symptoms, but also secondary questions about structural changes.

Recent unpublished trials on Pentosan Polysulfate Sodium (PPS) for osteoarthritis (OA) have focused on evaluating its effectiveness, safety, and the duration of treatment effects in knee OA pain management. Two significant trials have been highlighted:

Treatment Effects of Subcutaneous Injections of Pentosan Polysulfate Sodium vs. Placebo in Participants With Knee OA Pain : This study, which began on October 19, 2021, is a two-stage, adaptive, randomized, double-blind, placebo-controlled, multicentre trial. It aims to evaluate the dose and treatment effect of PPS compared with a placebo in participants with knee OA pain. The study's estimated primary completion date is October 15, 2024, with an overall completion date around December 6, 2024. The trial involves various interventions, including PPS administered twice weekly, once weekly, and a fixed dose once weekly, all compared against a placebo.
An Extension Study to Investigate The Duration of Treatment Effect and Re-treatment of Pentosan Polysulfate Sodium in Participants With Knee Osteoarthritis Pain : This interventional trial started on December 24, 2021, and aims to assess the duration of PPS's treatment effect and the outcomes of re-treatment in adults with knee OA pain. It's designed as a parallel assignment with an estimated enrollment of 938 participants. The study investigates the time from initial response to the loss of OMERACT-OARSI response through follow-up weeks 28 and 80, among other outcomes, with primary completion and study completion dates estimated for October 24, 2024.

Additionally, a pivotal trial examining PPS injections for knee OA, set to be the final step before potential approval, emphasizes the importance of these studies. This trial focuses on changes in bone shape, cartilage volume, and joint space width on MRI from baseline at weeks 28 and 80, indicating a thorough investigation into PPS's structural effects on knee joints affected by OA.

These studies are critical in advancing our understanding of PPS as a potential disease-modifying treatment for OA, specifically knee OA. By focusing on outcomes such as pain reduction, improvement in function, BUT ALSO STRUCTURAL and BIOCHEMICAL changes within the joint, these trials could significantly impact future treatment protocols for OA, pending their results and eventual publication. Given the long-term progressive nature of OA, it will take further longitudinal studies over many years to strongly support claims that PPS is a Disease Modifying Agent.

Conclusion

In the ever-evolving landscape of osteoarthritis treatment, Pentosan emerges as a testament to the relentless pursuit of innovation. As research unfolds, the hope is that Pentosan will not only enrich our arsenal against OA but also redefine what it means to live with this chronic condition.

FAQs About Pentosan and Osteoarthritis

What is Pentosan, and how does it work?

Pentosan Polysulfate Sodium (PPS) is a semi-synthetic polysaccharide derivative, initially used for treating bladder pain syndrome. In the context of osteoarthritis, Pentosan works by enhancing joint lubrication, reducing inflammation, and potentially encouraging cartilage repair. Its multi-pronged approach targets the underlying mechanisms of OA, offering not just symptomatic relief but also aiming to slow the disease's progression.

Can Pentosan reverse osteoarthritis damage?

While current evidence suggests Pentosan has disease-modifying properties, including reducing inflammation and improving joint function, there's no definitive proof it can reverse existing damage caused by osteoarthritis. However, its potential to protect cartilage and slow degeneration offers a promising avenue for reducing the impact of OA over time.

What are the potential side effects of Pentosan in OA treatment?

Pentosan is generally well-tolerated, with side effects being mild to moderate. Common side effects include gastrointestinal disturbances, headache, dizziness, and in rare cases, bleeding complications due to its mild anticoagulant effect. It's important for patients to discuss their health profile with their healthcare provider to assess the risk-benefit ratio of Pentosan treatment.

How soon could we see Pentosan being used widely for OA?

The widespread use of Pentosan for osteoarthritis depends on the outcomes of ongoing clinical trials, regulatory approval processes, and its incorporation into treatment guidelines. While promising, it's a process that requires rigorous evaluation and time. Optimistically, if upcoming trials continue to validate its efficacy and safety, Pentosan could become a part of standard OA management within the next few years.

Why Exercise Testing is a great way to Benchmark your Health

Exercise testing is often done for athletes who are trying to benchmark their progress. However, it is also a reliable and useful test for people who want to understand their overall health, as fitness and strength are some of the best predictors of longevity. Exercise testing encompasses a range of assessments used to evaluate health, fitness, and performance in both clinical and athletic settings. Each type of test provides specific insights and has practical applications. Let's break down the methods and usefulness of each:

VO2 Max Testing:

Method: VO2 max, or maximal oxygen uptake, is often assessed using graded exercise tests on a treadmill or cycle ergometer. The test measures the maximum amount of oxygen an individual can utilize during intense exercise.
Usefulness: It's considered the gold standard for measuring cardiovascular fitness and aerobic endurance. Higher VO2 max values are associated with better endurance performance and cardiovascular health.

Strength Testing Including Grip Strength:

Method: Strength tests assess muscle force generation. Grip strength, a common strength test, is measured using a dynamometer. Participants squeeze the device as hard as possible.
Usefulness: Grip strength is a simple yet powerful predictor of overall muscle strength and is linked to health outcomes. For instance, lower grip strength is associated with increased mortality, disability, and health complications.

Power Testing:

Method: Power tests evaluate the ability to exert maximal force quickly. Common tests include vertical jumps or sprinting assessments.
Usefulness: Power is crucial in many sports and daily activities. Power testing can guide training and rehabilitation programs, especially in sports where explosive movements are key.

Lactate Threshold Testing:

Method: This involves exercising at increasing intensities while measuring blood lactate levels. The lactate threshold is the point at which lactate begins to accumulate in the blood.
Usefulness: Understanding lactate threshold helps in designing endurance training programs. Athletes can train at or near this threshold to improve their endurance performance and efficiency.

Balance and Functional Testing:

Method: These tests assess an individual's ability to maintain balance and perform functional movements. Common tests include the Functional Movement Screen or balance assessments like the Single-Leg Stand.
Usefulness: They are essential in rehabilitation settings and for older populations to prevent falls. In athletes, they help in identifying imbalances or weaknesses that could lead to injury.

Evidence from Research

Studies have consistently shown that VO2 max is a strong predictor of cardiovascular health and mortality risk. For example, a study in "The Journal of Physiology" highlighted its importance in assessing cardiac function in athletes and non-athletes.
Research in "The American Journal of Preventive Medicine" has demonstrated the predictive value of grip strength for mortality, morbidity, and disability.
Power tests like vertical jumps are widely used in sports science to evaluate athletic performance, as supported by research in "Sports Medicine".
The lactate threshold has been extensively studied for its implications in endurance training and performance, as seen in research published in "Medicine & Science in Sports & Exercise".
Balance and functional tests are key in fall prevention among older adults, according to studies in "The Journals of Gerontology".

In summary, exercise testing is a valuable tool in both health and performance contexts. It provides critical information for designing individualized training, rehabilitation, and health maintenance programs. Each test offers unique insights into different aspects of physical fitness and health.
