Abstract

The aim of this investigation was to establish if there were characteristic circadian rhyhtms in peak power and mean power. Thirteen female physical education undergraduate students, aged from 18-21 years, were measured for peak power and mean power (Wingate Anaerobic Test) at four time points: 0300, 0900, 1500, and 2100 hours. Peak power was defined as the highest mechanical power that is elicited during a 5-sec period and mean power was defined as the average power that is sustained throughout a 30-s period. A significant circadian rhythm was found for the peak power (F = 3.22, p = 0.030). The mean peak power at 1500 h was about 7 higher (p<.05) than at 0300 h. Also a tendency to circadian rhythm was observed in mean power (F = 3.99, p = 0.01) being about 16 and 15 higher respectively (p<0.05) at 1500 h and 2100 h than at 0300 h. Based upon the particular protocol used, it was concluded that there are characteristic circadian rhythms in peak power and mean power. Verf.-Referat
