Cardiorespiratory fitness is an important measure to evaluate the current health status of your client. However, directly measuring VO2 max is expensive, time-consuming, and often unsafe depending on your client’s health status. The ‘Exercise Testing’ application can overcome these limitations by accurately and reliably predicting your client’s VO2 max by using sub-maximal testing methods. ‘Exercise Testing’ uses the linear relationship between heart rate and cardiac output to predict your client’s VO2 max.
