VO2MAX

A clear link exists between maximal oxygen consumption (VO2max) of the body and cardiorespiratory fitness because oxygen delivery to tissues is dependent on lung and heart function. VO2max (maximal oxygen uptake, maximal aerobic power) is the maximal rate at which oxygen can be used by the body during maximal exercise; it is related directly to the maximal capacity of the heart to deliver blood to the muscles. VO2max can be measured or predicted by fitness tests (e.g. maximal exercise tests, submaximal exercise tests, Polar Fit- ness Test). VO2max is a good index of cardiorespiratory fitness and a good predictor of performance capability in endurance events such as distance running, cycling, cross-country skiing, and swimming.

VO2max can be expressed either as milliliters per minute (ml/min = ml ■ min-1) or this value can be divided by the person’s body weight in kilograms (ml/kg/min = ml ■ kg-1■ min-1).

TRAINING BENEFIT

Training Benefit gives you textual feedback on your performance for each training session helping you better understand the effectiveness of your training. You can see the feedback in Flow app and Flow web service. To get the feedback, you need to have trained at least a total of 10 minutes in the heart rate zones. Training Benefit feedback is based on heart rate zones. It reads into how much time you spend and how many calories you burn in each zone.

The descriptions of different training benefit options are listed in the table below
