The current investigation was undertaken to determine the effects of active versus passive recovery on work performance during repeated bouts of supramaximal exercise. Six healthy sedentary subjects and 9 moderately trained healthy hockey players performed serial 30-second Wingate anaerobic power tests (WAnT) on a bicycle ergometer interposed with 4 minutes of active recovery at a work rate corresponding to 28 % of VO(2)max or passive recovery at rest. Peak power, mean power, total work achieved, and fatigue index were calculated for the serial WAnT. Capillary blood lactate was determined at 5-minute intervals after the last WAnT during 30 minutes of active or passive recovery. Mean power was significantly greater during active recovery in sedentary subjects when compared with passive recovery (388 +/- 42 vs. 303 +/- 37 W, p < 0.05), but did not differ according to recovery mode in moderately trained hockey players (589 +/- 22 W active vs. 563 +/- 26 W passive, p = 0.14). Total work achieved significantly increased during active when compared with passive recovery in sedentary subjects (34 890 +/- 3768 vs. 27 260 +/- 3364 J, p < 0.02) and moderately trained hockey players (86 763 +/- 9151 vs. 75 357 +/- 8281 J, p < 0.05). Capillary blood lactate levels did not differ during active when compared with passive recovery in sedentary subjects but were significantly lower during active when compared with passive recovery in moderately trained hockey players. These data demonstrate that active recovery at a work rate corresponding to 28 % of VO(2)max increases total work achieved during repeated WAnT when compared with passive recovery in sedentary subjects and moderately trained hockey players.
