Performance and Fitness Markers

Functional markers tied closely to longevity outcomes, especially cardiorespiratory fitness, muscular strength, and real-world resilience.

These profiles can overlap deliberately with the editorial layer so major topics exist as explainer content and as directory records.

VO2 Max

A functional performance marker that estimates maximal oxygen uptake and is strongly associated with all-cause mortality risk.

Cardiorespiratory fitness

This branch intentionally overlaps with the editorial and reference layers so important concepts can be found from more than one angle.

Article

VO2 Max and Longevity

VO2 max measures how much oxygen your body can use during hard exercise. Higher cardiorespiratory fitness is linked with lower mortality risk, but a fitness score is not a personal lifespan forecast.

Article

Grip Strength and Aging

Why a simple handgrip measurement has become one of the most studied biomarkers in aging research.
