Definition
Fitness Index (FIX) is an estimate of cardiorespiratory fitness (CRF) reported as a score from 0 to 100, with higher scores indicating better cardiorespiratory fitness.
Background
The Fitness Index is derived from an estimate of cardiorespiratory fitness (CRF) and is reported as a score ranging from 0 to 100, where higher scores indicate better cardiorespiratory fitness. The estimate is generated using physiological and health indicators derived from facial blood flow measurements, including heart rate, heart rate variability, cardiac workload, vascular capacity, health risk indicators such as pre-diabetes and hypercholesterolemia risk, together with demographic factors including age, sex, and waist-to-height ratio.
