The critical power model is a mathematical approach used to predict an athlete’s performance in endurance sports. It is based on the concept that an athlete has a critical power output, which is the highest sustainable power output that can be maintained for a prolonged period without fatigue.
The critical power model involves performing a series of tests at different intensities to determine an athlete’s critical power output and their so-called “W’ balance” (the amount of work that can be performed above critical power before fatigue sets in). Using this information, coaches and athletes can predict how long an athlete can sustain a given power output and adjust training accordingly.
The critical power model is commonly used in endurance sports such as cycling, running, and rowing, as it provides an objective measure of an athlete’s performance capabilities. This can be useful for setting goals, developing training plans, and evaluating performance over time.
