Critical Power as a Predictor of Performance in a Bicycle Time Trial

PDF Version Also Available for Download.

Description

Certain measures of aerobic power have been shown to have a high relationship with endurance performance. Critical power (CP) has also been shown to be well correlated to endurance performance, but few studies have evaluated its use in a competitive scenario. In this study, cardiorespiratory-metabolic measures were evaluated in 13 highly trained cyclists to determine their relationship to performance in a 17 km time trial. Critical power, determined from the nonlinear power-time model, was also evaluated to determine its relationship to performance in a 17 km time trial. Results indicate that the traditional indicators of V02max and ventilatory anaerobic threshold ... continued below

Description

Certain measures of aerobic power have been shown to have a high relationship with endurance performance. Critical power (CP) has also been shown to be well correlated to endurance performance, but few studies have evaluated its use in a competitive scenario. In this study, cardiorespiratory-metabolic measures were evaluated in 13 highly trained cyclists to determine their relationship to performance in a 17 km time trial. Critical power, determined from the nonlinear power-time model, was also evaluated to determine its relationship to performance in a 17 km time trial. Results indicate that the traditional indicators of V02max and ventilatory anaerobic threshold were well correlated to TT performance (r=-0.86, r=-0.79, respectively). The principal finding from this study was that performance in a bicycle time trial is related to CP at least as well as to cardiorespirator-ymetabolic measures. In fact, the results fromthis study suggest that the relationship between performance and CP is stronger (r=-0.89). Use of the critical power concept is attractive because testing requires only a cycle ergometer and a stopwatch to estimate a parameter of aerobic fitness.
