NCT07393841
Molecular Indicators of Systematic Fitness
The goal of this study is to characterize associations between cardiorespiratory fitness, as measured by VO₂max/VO₂peak, and blood-based molecular measurements in adults. This is an observational study where research staff measures VO₂max/VO₂peak and collects fasted, resting blood samples on the same day. The main questions it aims to answer are: 1. Can a multi-analyte blood panel accurately predict directly measured VO₂max/VO₂peak? 2. How do these blood-based features vary across age, sex, and self-reported or documented physical activity profiles? 3. Are the predictor analytes able to capture changes in VO₂max/VO₂peak caused by a self-directed intervention (e.g., training for a marathon)? 4. What is the analytic reliability of the predictor biomarkers?
