This study aimed to determine the effect of 3 different recovery modes (passive [PR], active [AR], and dynamic stretching [SR]) on exercise time to exhaustion (Tlim) and cardiorespiratory and blood lactate responses during supramaximal exercise. Exercise sessions consisted of 2 series of 4 repeated, intermittent supramaximal cycling exercise interspersed in random order with PR, AR, or SR before the supramaximal continuous cycling time limit (Tlim) exercise test performed at 120% of maximal aerobic power. Ten healthy volunteer soccer athletes aged 25.7 ± 2.4 years participated in this study. During each exercise session, heart rate (HR), oxygen consumption ([latin capital V with dot above]o2), blood lactate concentration, and Tlim exercise performance were recorded. Higher values were obtained in HR (p < 0.01) and in [latin capital V with dot above]o2 (p < 0.001) with SR and AR compared with PR. Moreover, lower blood lactate concentration (p < 0.01) was observed with SR and AR compared with PR. A greater Tlim exercise duration was obtained for SR compared with AR (p < 0.05) and PR (p < 0.01). Dynamic stretching appeared as the best recovery mode to enhance performance and cardiorespiratory and lactate responses during intermittent supramaximal cycling exercise.
