        The purpose of this study is to provide basic data for selecting prominent athletes by analyzing morphological features of the excellent track and field athletes. 80 high school athletes were selected as the subjects and then they were divided into 8 groups (10members in each group) according to their level and sports events. After measuring skinfolds, girths, breadths, the trochanterion, and forms, the mean value and standard deviation of the raw data were calculated in relation to the treatment period and the group. And two-way ANOVA by repeated measurement was used to identify the average difference. The results of this study were as follows; First, the skinfolds of the throwing athletes were more than those of the sprint, jumping and long distance running athletes. Second, the girths of the excellent throwing athletes were bigger than those of the excellent sprint, jumping and long distance running athletes. And the girths of the non-excellent throwing athletes were bigger than the non-excellent sprint, jumping and long distance running athletes. Third, the breadths of the throwing athletes were broader than those of the sprint, jumping and long distance running athletes. And the breadths of the sprint and jumping athletes were broader than those of the long distance athletes. Fourth, the trochanterion of the sprint, jumping, throwing athletes were bigger than those of the long distance running athletes. Fifth, the throwing athletes` endomorphic and mesomorphic were larger than those of the sprint, jumping and long distance athletes. The ectomorphic of spring, jumping and long distance athletes were larger than that of the throwing athletes. In conclusion, the somatotype of the throwing athletes was bigger than other sports events athletes. Sprint and jumping athletes` somatotype were relatively same and that of the long distance athletes` was smaller. The best condition of the athlete`s body figure will enhance the performance of them. Finding right body figure for each sport events when selecting athletes will be very useful.

        단계적 저항운동과 걷기 및 운동중지가 여성노인의 평형성과 슬관절 등속성 근기능에 미치는 영향

        The purpose of the study was to examine an effect of gradual resistance exercise, walking and detraining on fall-related fitness and isokinetic muscular function of female elderly. To achieve the purpose, the study examined changes of balance property (Dynamic, passive), knee joint muscular function (Muscular strength, muscular endurance) through training for 12 weeks and detraining for 4 weeks by dividing female elderly into a gradual resistance group, a walking group and a control group. As the result, the study got the following conclusion. Flexibility, balance property after training in the gradual resistance group and the walking group, but were kept only in the gradual resistance group after detraining. In muscular strength, the left extensor muscle of knee joint was increased only in the gradual resistance group after training and was reduced after detraining. The left flexor muscle of knee joint was increased in the gradual resistance group and the walking group after training and was reduced in the two groupsafter detraining. The right extensor muscle of knee joint was increased in the gradual resistance group and the walking group after training and was kept only in the gradual resistance group after detraining. In muscular endurance, the left extensor muscle of knee joint was increased in the gradual resistance group and the walking group after training, but was kept only in the gradual resistance group after detraining. The right extensor muscle of knee joint was increased in the gradual resistance group and the walking group after training and was kept in the two groups after detraining. The left/right flexor muscles of knee joint didn`t have any difference.
