TL;DR
At Rohini Mundra, we treat cardiorespiratory fitness, often expressed as VO₂ max, as a useful health coach trend, not a diagnostic verdict. A 2026 Formula 1 review highlights why longitudinal context matters, while current research shows both the health relevance of fitness and the limits of wearable estimates. We explain how to use the data responsibly.
Health Coach Takeaway from Formula 1 Health Research
On 18 February 2026, a peer-reviewed Formula 1 review examined the demands of a calendar with 24 races across 21 countries, including heat, travel and sustained physical stress.
At Rohini Mundra, we think a health coach should treat cardiorespiratory fitness, often expressed as VO₂ max, as a useful trend rather than a diagnosis. It can inform client-led activity and recovery conversations, but it cannot replace medical assessment, blood-pressure screening, or the wider context that gives a changing score meaning.
We unpack what the research confirmed, why fitness data matters, and how coaches can use it without turning a dashboard score into a health claim.
What the Formula 1 Review Actually Confirmed
The review combined motor-racing evidence with structured interviews of elite performance coaches. It found that drivers contend with g-forces, heat and long-haul travel, while meaningful physiological data during driving remains limited. That gap matters because even highly resourced performance settings cannot make sound decisions from one convenient number alone.
We see a clear lesson for a health coach: elite sport offers useful discipline around preparation and recovery, not a template for making sweeping claims about everyday clients. Cardiorespiratory fitness can be a valuable outcome to discuss, but it belongs beside personal goals, habits, symptoms and appropriate clinical care.
For a useful wider conversation about behaviour rather than biometric hype, our health coaching evidence shows why practical habits still deserve as much attention as the latest metric.
Why a Health Coach Should Track Cardiorespiratory Fitness
The case for tracking fitness does not rest on elite sport. A 2024 review covering 3.8 million observations found that each one-MET increase in cardiorespiratory fitness was associated with a 14% lower all-cause mortality risk and a 16% lower cardiovascular mortality risk. These are observational associations, but they make cardiorespiratory fitness a serious health signal worth understanding. Fitness evidence
That context is important because cardiovascular diseases caused an estimated 19.8 million deaths in 2022, or about 32% of all deaths globally. We should not turn that burden into fear-based coaching, but we should be honest that sustainable movement and fitness are more meaningful than chasing cosmetic data points. Global burden
VO₂ Max Is a Fitness Signal
VO₂ max describes the maximum amount of oxygen the body can use during intense exercise. It is commonly used to represent cardiorespiratory fitness, and the American Heart Association has argued that fitness should be considered a clinical vital sign. We use that framing carefully: a strong signal is not a complete health profile. Clinical vital sign
Association Is Not Diagnosis
A rising score may reflect improved conditioning, but it cannot tell us why a person feels unwell, whether medication is affecting performance, or whether a health condition needs assessment. We should help clients ask better questions, not imply that a wearable has supplied the answer.
Better Than a Single Score Fixation
For most clients, the real value lies in noticing whether a consistent movement routine, better recovery or a realistic training plan is producing a meaningful trend. That is a more durable conversation than declaring one score “good” or “bad.”
How Health Coaches Can Use a VO₂ Max Trend
We recommend treating the number as the start of a conversation, not its conclusion. A useful process makes the source of the estimate clear, compares like with like, and keeps the client in control of their own health goals.
Separate Measurement from Estimate
Direct cardiopulmonary exercise testing is the reference method. Consumer devices estimate VO₂ max, and a review of 14 validation studies found that exercise-based estimates performed better than resting estimates, while individual error could still be wide. We would use an estimate for a comparable trend, not as proof of a person’s clinical fitness. Wearable review
Create a Comparable Baseline
We would record the device or test used, the activity that generated the estimate and any obvious context, such as a recent illness, disrupted sleep or a break from exercise. When the method changes, the number may change for technical reasons rather than physiological ones.
Stay Inside Coaching Scope
A health coach can support client-led goals, routines, accountability and evidence-based resources. Coaches do not independently diagnose, interpret medical data or prescribe exercise, which is why a concerning change belongs in an appropriately qualified clinical conversation. Coaching scope
For coaches building clearer client communication around tools and evidence, our health tools guide offers another practical starting point.
What Health Coaches Should Monitor Next
The immediate next step is not to buy another wearable or promise a dramatic improvement. We would help a client choose one consistent way to observe fitness, then connect the trend to the behaviours they can actually sustain.
Adults can build fitness through regular movement. Global guidance recommends 150 to 300 minutes of moderate aerobic activity weekly, or 75 to 150 minutes of vigorous activity, alongside muscle-strengthening activity on two or more days each week. Activity guidance
-
Log The Method: Keep the device, activity type and conditions as consistent as practical.
-
Watch The Trend: Discuss change across multiple readings, not one unusually high or low result.
-
Escalate Appropriately: Encourage clinical input when symptoms, medical history or a treatment plan make interpretation more complex.
Work with Rohini Mundra
At Rohini Mundra, we help health coaches make timely evidence useful without turning it into hype. This research moment calls for stronger client conversations: define what a score estimates, agree on the client’s goal, preserve the surrounding context and know when a clinician belongs in the discussion. We can help you turn that discipline into clear positioning, practical content and an offer that earns trust. If your audience is overwhelmed by dashboards and health claims, we will shape a simpler, more credible message around the decisions they actually need to make. Start with contact Rohini.
FAQs on Health Coach
What Does VO₂ Max Measure?
VO₂ max estimates oxygen use during hard exercise. It reflects cardiorespiratory fitness, but it becomes useful only when viewed as a trend alongside personal context.
Can a Wearable VO₂ Max Score Replace a Clinical Test?
No. Wearable estimates can support a consistent trend, but individual error can be wide. Use a supervised clinical assessment when medical interpretation or treatment decisions are needed.
What Can a Health Coach Do with a VO₂ Max Score?
A health coach can help clients set goals, establish habits and review trends. The coach should not diagnose, prescribe exercise, or treat a score as medical evidence.
