The purpose of this study is to compare and analyze the changes in the maximum muscular strength and angle of maximum muscular strength of knee joint of male national alphine skiers before and after the seasons and to identify the characteristics of the atheletes’ physical development. We believe that the results can be utilized in enhancing the alphine skiers’ performance level. The subjects of this study are 8 national male alpine skiers who are registered with Korean Ski Association, within ranking 10 and participating in the game. Isokinetic knee joint muscular strength employed Cybex HUMAC NORM. in order to verify the difference of measurement of knee-joint isokinetics according to the training program, t-test was performed and the level of significance for all the statistic analysis was set for a=.05. According to results, the following conclusions were obtained. The maximum muscular strength and maximum muscular strength per body weight of the knee joint shows greater measurements after a season and maximum extensor muscular strength and %BWmaximum extensor muscular strength showed noticeable difference(p<.05). The Angle of maximum muscular strength of the knee joint shows greater measurements after a season and right angle of maximum extensor muscular strength and angle of maximum flexor muscular strength showed noticeable difference(p<.01). When the rate of muscular endurance of the knee joints were measured, there has no a statistically noticeable difference. This means that in order to improve the performance level of the ers, it should be a priority to maintain and develop the level of the physical strength at the beginning of the season until the end of the season. For that, in addition to the training on the snow a continued physical training should be accompanied.
