The purpose of this study was to examine if physiological and psychological responses would vary when the power output was maintained during repetition exercise. Healthy male subjects (n=8) performed ten sprint-sets including 10-s maximal pedaling followed consecutive active [170-s, 0 kilopond 60 revolutions per minute (rpm)] and passive recovery [180-s, on cycle ergometer]. Integrated electromyography (IEMG) and mean power frequency (MPF) of using the data of the EMG from vastus lateralis during 10-s maximal pedaling were determined. IEMG was divided by mean rpm exerted during 10-s maximal pedaling to give average rectified value (ARV). Maximal power output (MaxP) and mean power output (MeanP) during 10-s maximal pedaling remained unchanged from 1st to 10th set. Three parameters [arousal, concentration and motivation] of visual analog scale (VAS) were used for evaluating psychological response. The three parameters did not change. Blood lactate concentration (La) significantly increased (P<0.05). The ARV significantly decreased (P<0.05) whereas the MPF significantly increased (P<0.05). Therefore, it is concluded that physiological parameters changed in the repetition exercise established in the present study.
