ABOUT OUR LAB
Clinical Performance Science in Orange County
VO2 Max Orange County provides research-grade metabolic and lactate testing for endurance athletes and active adults. We bring university-level physiological testing into an accessible, athlete-first setting.
Our Background & Cycling Pedigree
VO2 Max Orange County operates inside Lebel Bicycles, South Orange County’s destination for high-performance road, gravel, and mountain cycling.
Working with competitive athletes, we saw that many athletes based their pacing on generic age formulas or wrist-based smartwatch estimates that missed their real thresholds by 15 to 20 beats.
To provide genuine clarity, we installed a dedicated in-house physiological laboratory to measure performance and verify real training adaptations.
We used this facility to benchmark our racers, optimize race pacing, and validate aerobic development season after season.
As runners, triathletes, and fitness enthusiasts sought the same diagnostic rigor, we expanded our services to the wider endurance community.
Today, our lab operates as an independent testing center open to anyone committed to training smarter with objective data.
Who We Are
VO2 Max Orange County is a specialized center serving endurance athletes, runners, and active adults.
We are the VO2 Max testing lab of Lebel Bicycles. Based in San Juan Capistrano. This is a place that measures your oxygen the way sports science measures it.
We are equipped with an in-house research-grade metabolic cart. It is the gold-standard tool used to calculate your VO2 max and your resting metabolic rate (RMR). Direct gas analysis is how you get zones you can train from.
We use this lab ourselves to track performance of Lebel Bicycles cyclists. By visiting us, you get the same instrument and the same protocol.
RESEARCH-GRADE LAB
Our Testing Technology
Consumer wearables estimate cardiorespiratory fitness through optical skin sensors and population averages, which can fluctuate with heat, fatigue, or movement.
Our laboratory utilizes an in-house research-grade metabolic cart. By directly analyzing breath-by-breath gas exchange, it provides the clinical gold standard in cardiovascular measurement.
This allows us to measure your exact physiological response across every stage of exercise with clinical precision.
What We Measure Directly
Oxygen Consumption (VO2)
The exact volume of oxygen your muscles utilize at each pace or power output.
Carbon Dioxide Production (VCO2)
Your respiratory system's efficiency in buffering metabolic acidity.
Ventilatory Threshold 1 (VT1)
The physiological ceiling for true Zone 2 aerobic training and maximum fat oxidation.
Ventilatory Threshold 2 (VT2)
Your anaerobic threshold, marking the upper limit of sustainable high-intensity work.
Blood Lactate (mmol/L)
Direct chemical validation from finger-prick samples to verify threshold transitions.
DISCIPLINES
Sport-Specific Testing Options
Cyclists
Mount your personal road, gravel, or triathlon bike to our precision direct-drive smart trainer. You test in your real riding position, on your own saddle, using your preferred shoes.
Runners
Test on our commercial running treadmill with graded protocols matched to your typical race pace for sport-specific running zones.
Triathletes
Dial in your bike power targets and run paces to optimize energy management and prevent late-race fatigue on event day.
Longevity & Health Seekers
Establish an objective cardiorespiratory fitness baseline to track cardiovascular health and ensure your Zone 2 cardio sessions remain truly aerobic.
Private Laboratory Experience
Every testing session is conducted one-on-one in a private setting. Our staff guides you through warm-up, monitors test progression, and sits down with you afterward to ensure you understand every metric in your report.
