Perceived vs. Objective Strain in the WHOOP Population

May 27, 2016

While one of the widely used metrics for capturing exercise intensity – rate of perceived exertion (RPE) – offers some insight into the physical load of a given workout, it is neither accurate nor precise, and thus can prompt the athlete or his coach to make inappropriate training decisions. Moreover, subjectively rating different types of activities of different durations on a single scale is particularly prone to biases.

The WHOOP Strain Score is an objective and consistent measure of cardiovascular strain that enables an athlete or coach to correctly assess the physiological stress of training through individualized strain measurements. Hence, it provides the information necessary to plan recovery, nutrition and future training in an optimal way, leading to improved performance levels and decreased risk of injury.
