FITNESS INDEX
Your MSC-HR10/20 will generate a fitness index based on your aerobic fitness. This index is dependent
and limited by the body’s ability to deliver oxygen to the working muscles in training. It is often meas-
ured by maximum oxygen uptake (VO2 Max), which is defined as the highest amount of oxygen that can
be utilized when exercising at an increasingly demanding level. The lungs, heart, blood, circulatory sys-
tem, and working muscles are all factors in determined VO2 Max. The unit of VO2 Max is ml/kg min.
The higher the index, the fitter you are. See the tables below for a rough guide to what your fitness index
means. Your fitness index is a reference and can be adjusted by changing your personal data.
