The single most validated biomarker for athletic performance and long-term health span — measured with clinical-grade precision at Plus10.
View Testing Options & PricingVO2 max is the maximum rate at which your body can consume oxygen during intense exercise. It is not an estimate. It is not a prediction based on your age, weight, and a treadmill formula. It is a direct, breath-by-breath measurement of your aerobic engine at full capacity — and it is the single most validated biomarker for both athletic performance and long-term health span.
Research published in JAMA Network Open and the Cleveland Clinic Proceedings has established that VO2 max is among the strongest predictors of all-cause mortality — stronger than smoking, diabetes, or hypertension as an independent variable. Put simply: how much oxygen your body can use under stress tells us more about how long and how well you will live than almost any other number in medicine.
At Plus10 in Flower Mound, we measure yours with clinical-grade equipment and interpret the results with the context that makes them actionable.
During a VO2 max test, you exercise on a treadmill or bike at progressively increasing intensities while wearing a mask connected to a metabolic analyzer. The system captures every breath — measuring the precise volume of oxygen you inhale and the carbon dioxide you exhale.
As intensity rises, your body demands more oxygen. At some point, oxygen consumption plateaus even as effort continues to increase. That plateau is your VO2 max, expressed in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min).
VT1 and VT2 — the exact intensities where your breathing shifts
Physiologically determined zones, not age-based formulas
Exact intensity for maximum fat burn vs. carbohydrate
How effectively your body uses oxygen at all intensities
The short answer: anyone who trains and wants to stop guessing.
Endurance athletes — runners, cyclists, triathletes, ultra-distance competitors — use VO2 max testing to dial in training zones with precision. When your marathon training plan says “easy pace,” you need to know exactly what that means for your physiology, not someone else’s.
Longevity-focused individuals use VO2 max as a baseline health metric and track it over time. If your VO2 max is in the bottom quartile for your age, the research is clear: improving it meaningfully reduces your risk of cardiovascular disease, metabolic dysfunction, and early death.
People returning to fitness after a break, an injury, or a major health event use the test to establish a safe, effective starting point. Training at the right intensity from day one accelerates progress and reduces injury risk.
Competitive athletes in any sport — from CrossFit to soccer to MMA — use VO2 max data to identify whether aerobic capacity is a limiter in their performance.
Some of our clients drive two or more hours to reach Plus10 for this test. They do it because the quality of the data — and the quality of the interpretation — is not available closer to home.
A VO2 max test at Plus10 typically takes 45 to 60 minutes from check-in to debrief:
Avoid heavy meals 3–4 hours before the test. No caffeine for at least 4 hours. Wear athletic clothing and shoes appropriate for treadmill running or cycling. Stay hydrated but do not overhydrate.
Most VO2 max tests available to consumers are isolated events. You get a number, maybe a chart, and you leave. The data sits in a PDF on your phone and never connects to anything.
At Plus10, your VO2 max test is one data point in a comprehensive performance picture. We integrate your results with DEXA body composition data, lactate threshold testing, resting metabolic rate analysis, and — if applicable — continuous glucose monitor data to build a complete physiological profile.
Our on-site Nurse Practitioner adds a clinical dimension that no other testing facility in the DFW market offers. If your results suggest underlying cardiovascular concerns, metabolic dysfunction, or other health considerations, you have immediate access to medical-level guidance — not a referral to someone who has never seen your data.
This is not a strip mall testing kiosk. Plus10 is a private, appointment-only facility at 400 Gerault Road in Flower Mound. No crowds. No distractions. Just you, the equipment, and a team that knows how to use it.
Your heart rate zones from a formula are wrong. Your fitness tracker’s VO2 max estimate is wrong. A VO2 max test gives you the specific data your training requires — and at Plus10, we make sure you know exactly what to do with it.
