Muscle Biomarkers

VO2 max (mL/(kg-min))

Gender specific Cardiovascular
Optimal range: 50.0 - 90.0 mL/(kg-min)

Also known as: VO2 max, maximal oxygen uptake, max aerobic capacity, aerobic capacity test, oxygen consumption test

5 testing methods 6 lifestyle factors Whole Blood

SmO2 (% time<10%) (%)

Muscle
Optimal range: 0 - 10 %

3 testing methods 5 lifestyle factors Blood Oxygen Saturation is typically derived from capillary, venous, or arterial blood gas analysis. For SmO2 testing, focus is on muscle tissue oxygenation specifically and therefore would be more focused on near-infrared spectroscopy (NIRS) sensor readings from tissues rather than traditional blood samples.
