About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in
milliliters) you can consume per minute per kilogram
of body weight at your maximum performance. In
simple terms, VO2 max. is an indication of athletic
performance and should increase as your level of
fitness improves. The f
ē
nix 5X device requires wrist-
based heart rate or a compatible chest heart rate
monitor to display your VO2 max. estimate.
