The strongest predictor of longevity and performance, now available locally

VO2 Max is the gold standard for cardiovascular fitness. It reflects how the heart, lungs, and cells work together, and provides a clear benchmark for improving healthspan and performance.”

BRISTOL, CT, UNITED STATES, January 15, 2026 /EINPresswire.com/ -- MetaLab by Confidia highlights VO2 Max testing through the PNOE system, a diagnostic tool widely used in clinical research and specialized performance centers, now accessible to the local community.

According to Dr. Kevin Greene, Founder of Confidia Health Institute, “VO2 Max is the gold standard for cardiovascular fitness. It reflects the performance of the heart, lungs, and cells working together, and it’s one of the strongest predictors of both longevity and chronic disease risk. By measuring it directly, we give patients a clear benchmark to improve their healthspan, not just their lifespan.”

VO2 Max — the maximum amount of oxygen the body can use during exercise — is recognized by the American Heart Association as one of the strongest indicators of cardiovascular health and longevity. Through PNOE testing, results are compared to population norms, creating a clear benchmark of overall physiological performance.

Validated against the COSMED Quark CPET, a leading system in cardiopulmonary testing, the PNOE system delivers precise insights that go far beyond what consumer wearables can provide.

PNOE VO2 Max testing analyzes 23 physiological biomarkers, delivering a lab-grade view of cardiovascular and metabolic function that goes well beyond surface-level metrics.

MetaLab designed its VO2 Max testing experience to be both engaging and individualized. Patients may complete testing using either a treadmill or cycle ergometer, with protocols tailored to their activity level and experience. Each session is fully coached, with music selected to match pacing and intensity, and includes a structured post-test recovery period.

After testing, patients have the option to review their results through a virtual or in-person consultation with Dr. Greene or another MetaLab physician. During this insurance-covered review, patients receive personalized guidance outlining training frequency, intensity, and duration based directly on their VO2 Max results.

For individuals interested in nutrition and metabolic efficiency, MetaLab also offers a separate PNOE Resting Metabolic Rate (RMR) assessment. RMR testing provides a personalized macronutrient profile and energy utilization breakdown. When combined, VO2 Max and RMR testing offer a more complete picture of both performance capacity and overall metabolic health.

VO2 Max testing is now available by appointment at MetaLab, located inside Confidia Health Institute’s Bristol office at 508 Birch Street. To learn more or schedule an appointment, visit ConfidiaHealthInstitute.com/Metabolic-Lab.
