Cardiorespiratory fitness is the single strongest predictor of lifespan we can measure. We measure it directly — not by formula — under physician supervision.
Duration
~45 minutes
Method
Direct gas analysis
Results
Same day
Supervision
Physician + ECG
A VO2 max test in Sofia at Blue Longevity Clinic uses direct breath-by-breath gas analysis on a bike or treadmill. It takes around 45 minutes, is supervised by a physician with ECG monitoring, and delivers your maximal oxygen uptake, ventilatory thresholds and personal training zones the same day.
Large cohort studies place low cardiorespiratory fitness alongside — and often above — smoking, type 2 diabetes and hypertension as a mortality risk factor. Moving out of the lowest fitness quintile produces the largest single risk reduction of any measurable variable.
Unlike most biomarkers it is directly trainable. A 10–20% improvement within 12–16 weeks is realistic for most people, and it moves cardiovascular, metabolic and cognitive outcomes simultaneously.
Workload increases in stages every one to three minutes until you reach your individual ceiling. You wear a gas-analysis mask throughout while we monitor ECG, heart rate and perceived exertion.
Beyond the VO2 max number you receive aerobic and anaerobic thresholds, respiratory exchange ratio, heart-rate and power zones, and an assessment of metabolic flexibility — how efficiently you switch between fat and carbohydrate as fuel.
