This is an observational study where research staff measures VO₂max\u002FVO₂peak and collects fasted, resting blood samples on the same day. The main questions it aims to answer are:\n\n1. Can a multi-analyte blood panel accurately predict directly measured VO₂max\u002FVO₂peak?\n2. How do these blood-based features vary across age, sex, and self-reported or documented physical activity profiles?\n3. Are the predictor analytes able to capture changes in VO₂max\u002FVO₂peak caused by a self-directed intervention (e.g., training for a marathon)?\n4. What is the analytic reliability of the predictor biomarkers?",[24,25,26,27,28,29],"Healthy Adult","Fitness Testing","Athlete","Aging","Exercise Physiology","Human Performance",[31,32,33,34,35,36,37,38,39],"VO2peak","VO2max","cardiorespiratory fitness","proteomics","blood biomarkers","cardiovascular health","oxygen transport","exercise performance","functional capacity","RECRUITING","2026-02-02",{"date":43,"type":44},"2026-02-06","ACTUAL",{"date":46,"type":44},"2026-01-05",{"date":48,"type":20},"2028-05-10",{"name":50,"class":51},"VO Health, Inc.","INDUSTRY",""]
