We love it when complex physiological markers get a clear, relatable explanation through storytelling!

Here is the brilliant work from Andrea Zignoli, in collaboration with Ross Arena and Marco Meucci:

What do exercise oscillatory ventilation and your shower have in common? 〰️ 🚿

Imagine you are taking a shower, but the water is too cold. 🔵
You move the handle to make it hotter. Nothing happens.
You move it again. And again. ↗️↗️

All of a sudden, the water is scalding hot and you burn your skin. 🥵
So you move the handle again, all the way down. ↘️↘️
A few seconds later, the water is too cold again, and you are about to freeze. 🥶

After a couple of iterations, maybe you finally get it right. 🫠

What is going on? 🤔

You are trying to regulate the water temperature based on what you are sensing. 🫴

‼️ But you are responding to information that is already out of date‼️
The water you just heated is still travelling through the pipes.⏳

That combination of feedback + delay can make a system oscillate.

===============

So what does this have to do with exercise oscillatory ventilation (EOV)?

A similar control problem can occur in the regulation of breathing.
During exercise, rising CO2 and changes in pH are detected by the respiratory control system, which adjusts ventilation. 🧠🩸

But the information reaching the controller and the resulting changes in blood gases are separated by physiological delays.

Imagine you are exercising and CO2 is rising.
The respiratory controller increases ventilation. ↗️↗️
But the effect of that increase is not instantaneous.

By the time the system "sees" the result, the state it is responding to has already changed. ⏳

If the feedback is sufficiently strong relative to the delays and damping in the system, ventilation can start to oscillate.

And when those oscillations persist during exercise, we call it EOV.

===============

I put together an interactive module in my course on Technology and Innovation in Sports, where you can play with this feedback system yourself:

VO₂max is too important to estimate. A metabolic cart measures it.

✅They help athletes track trends.
✅They provide motivation.
✅They offer a starting point.
⚠️But they are still estimates.

For Quenton Lanese, different platforms estimated his VO₂max at:
🟡Runalyze: 59
🟡Garmin: 68
🟡VDOT: 74.6

Then he completed a measured VO₂max test at the Podium Human Performance Lab with Khai Lam using the COSMED Q-NRG MAX.

✅Measured VO₂max: 81.65 ml/kg/min

That changes the conversation from: “What does the algorithm think?”
to: “What did the athlete actually demonstrate physiologically?”

And when you look at Quenton’s measured VO₂max, he places in the same general ~80s ml/kg/min range often reported for elite endurance runners

That shows why direct measurement matters. When performance decisions are based on physiology, estimates are not enough.

Thank you to Khai Lam and the Podium Human Performance Lab for advancing objective performance testing, and to Quenton Lanese for allowing us to share his story and data.

Looking forward to our fifth Health & Performance Collective meeting on September 9th at 3:00 PM CT.

I am excited to continue our conversation from August 13th, this time diving into a clinical topic: Wasserman’s 9-Panel Plot!

I'm thrilled to welcome Dr. Ross Arena as our guest speaker and subject matter expert!

We'll explore:
✅ How to navigate the 9-Panel Plot
✅ How to identify if a limitation originates from the heart or the lungs
✅ How to translate clinical findings into action

Bring your questions, share your experiences, and learn alongside colleagues.

🔥 The Great Intensity Debate: Zones vs. Thresholds 🔥

Are we looking at exercise prescription the wrong way?

When it comes to programming conditioning, coaches and physiologists often face a crucial crossroads: do we prescribe using broader Training Zones, or do we pinpoint specific Ventilatory Thresholds?

The data breakdown in our image perfectly illustrates this divide, but looking closely at these two models begs a few massive questions for how we coach:

- Who is this really for? Is zone training naturally better suited for fitness and wellness clients who thrive within a wider, more forgiving physiological range?

- What about the elites? Should high-performance athletes strictly use threshold-based training to target a razor-thin, highly precise physiological marker?

- The Ultimate Hybrid? What if the secret is blending the two? Should we be using precise thresholds for the prescription of the workout, but relying on broader zones for post-training quality control to ensure the person actually respected the plan?

We aren’t going to give you the answers right here; we want to explore the science and the application with you! If you are curious about how to best utilize these markers to elevate your programming, you won't want to miss our upcoming deep dive:

Exercise biochemistry can feel like navigating an intricate world, but bioenergetics is simply a high-tech factory producing the ultimate currency: ATP Golden Tickets 🎫✨

Dr. Ross Arena and I (Marco Meucci) are continuing our storytelling journey inside the human body, joined by our colleague Isaac Armando Chavez Guevara for The Fantastic Oxygen Voyage!

1. The Ingredients: Cocoa, Sugar, and Milk:
🍫 Fatty Acid Cocoa Beans: Processed via B-oxidation into Acetyl-CoA (the Master Chocolate Liquor).
🍬 Sugar Cane Depot: Glucose (raw sugar) is refined via glycolysis into Pyruvate ("Golden Syrup"), yielding a quick 2-ATP ticket bonus!
🥛 The Lactate "Milk" Shuttle: Pyruvate transforms into Lactate ("Milk"); not waste, but recycled fuel shuttled straight into the mitochondrial furnace!
🌪️ Universal Convergence: Whether starting as cocoa, sugar, or milk, everything converts to Acetyl-CoA before entering the Krebs Cycle.

2. The Assembly Line & The Ultimate Prize:
Electrons power Complexes I–IV, pumping protons to drive the ATP Synthase Turbine. This prints a continuous stream of ATP Golden Tickets that pay your muscle fibers to produce athletic movement!

3. Oxygen: The Powerful Factory Magnet:
Oxygen acts as a magnet at the end of the line, catching spent electrons to wash them away as water. This keeps the assembly line moving so the turbine never seizes.

Join COSMED’s Marco Meucci, PhD. and Eric Pyles, MEd.CSCS.TSAC-F.Pn1 for the webinar Ventilatory Thresholds & Training Zones: Applying Physiological Markers.

Explore the physiological significance of the ventilatory thresholds and maximal fat utilization, and how they serve as key markers for guiding endurance, threshold, and interval training.

We will moderate a discussion on how to translate test results into exercise prescription strategies to improve health, fitness, and performance.

Beyond VO2max: Asking the Right Question
Stop Chasing One Number, Start Designing Effective Programs

In Cardiopulmonary Exercise Testing (CPET), it's easy to focus solely on "How high is yourVO2max?

"Instead, the primary question should always be: "What specific question am I trying to answer for this individual?"

A data point is just a number until you translate it into actionable programming. The best test protocol is always the one that delivers the safest, most valid, and most interpretable physiological response for the person in front of you.

Here are examples of how to answer common questions across different populations:

- Professional Athlete
"What is my aerobic ceiling?"
"Where are my ventilatory thresholds and training zones?"
Maximal CPET with verification to capture aerobic power and precise metabolic transition to refine training strategies.

- Sedentary / Beginner"
"How fit am I, and where should I start safely?"
"How does my body respond to low-to-moderate intensities?"
Submaximal CPET testing to estimate VO2max and provide training guidance.

Older Adult / Clinical Client
"What intensity can I tolerate safely?"
"What are my physiological limiting factors?"
Conservative submaximal test or symptom-limited CPET prioritizing safety, blood pressure monitoring, and exercise tolerance.

Scientific update from Dr. Meucci …

Ventilatory Thresholds – The Key to Smarter, More Efficient Training

Breathing heavily as your workout gets tougher? You’re hitting your Ventilatory Thresholds!

First Ventilatory Threshold (VT1)
➡ The point where aerobic metabolism is still dominant.
➡ Breathing becomes noticeably deeper & talking starts to feel more difficult.
➡ Fat oxidation peaks around this intensity.

Second Ventilatory Threshold (VT2)
➡ The point where anaerobic metabolism dominates (lactate accumulates rapidly).
➡ Breathing rate is high & talking is nearly impossible.
➡ Close to your maximal sustainable effort.

🏆 Understand the ventilatory thresholds to train smarter!
✔ Use VT1 & VT2 to create your training zones.
✔ Train in the right zone to maximize endurance, speed & recovery.

Wondering how? Stay tuned!
