In ice hockey players, we have reported that there were significant differences in anaerobic power, between trained and untrained subjects, which were measured by using bicycle ergometer, and "20 M-Dash" on ice and earth. In this study, we attempted to assess training effects during a year by the power output of leg muscles. Subjects were the regular members (Foward : 3,Defence : 3) with experiences of more eight years. The subjects work bicycle at each load, 4,5,and 6 Kp, for ten seconds with maximum effort. The obtained results were as follows : 1) After training, the maximum power of Leg muscles were significantly higher than that of pre training. Muscle powers in the period prior to develop its value increased significantly. 2) The muscle power increased accoding to loads of 4,5,and 6 kp. 3) The maximum powers of foward players were higher than those of defence players. From these results, it is pointed out that training contents during a year were effective to increa se the power output of leg muscles. The muscle power of leg muscles by using bicycle ergometer must be useful to assess skating velocity in ice hockey players.
