Abstract

We measured the effective mechanical power which was sent out during 50 meter sprint running and the mechanical power in pedalling the bicycleergometer with maximum effort during a short time, and we analyzed the ability of power output. The results were as follows : (1) The sprinter A recorded higher running speed (10.47m/sec) and maximum value of effective power (160.3kgm/sec) than those of the ordinary man D (7.55m/sec, 76.5kgm/sec). (2) There was high correlation (Male: r=-0.77, n=22, p<0.001, Female: r=-0.93, n=9, p<0.001) between the maximum values per weight of effective power during running and 50 meter running times. (3) There was high correlation (Male: r=0.76, n=22, p<0.001, Female: r=0.79, n=9, p<0.02) between the maximum values per weight of effective power during running and maximum values per weight of pedalling power by bicycle ergometer. (4) There was high correlation (Male: r=-0.72, n=22, p<0.001, Female: r=-0.88, n=9, P<0.01) between the maximum values per weight of pedalling power by bicycle ergometer and 50 meter running times. As a result of the study it was found that the athletes had the excellent ability of power output made a good record of sprint running.
