1,500m-Run 및 Sit-up이 力道選手에 미치는 影響
李學來,玄友泳,曺泳八,柳根碩 漢陽大學校 1972 論文集 Vol.6 No.-
In order to check the effects of physical training (1,500m-run, Sit-up) to weight lifter's stamina, 14 physical education major students are selected at random. And 7 in A group(training group) others in B group (control group) are given some exercises as table-Ⅰ. After 44 days training, we recheck the A.B. groups to confirm physiological change and physical fitness (see table 4,5,6,7,8,9). The results may be sumerized as follows : 1. A group's muscular strength improve more than B group's 2. The very "sit-up" training we had, assist the power. 3. 1,500m-run and Sit-up training may assist to build the weight lifter's stamina.

Plyers in Sports may deccide their action according to any signal, the motion of opponents and the direction of a moving ball. This will have close relation with reaction time and shortening of reaction time plays an important role in winning a game. Consequently, we should know the various reaction time by analyzing the data, measuring reaction speed the center of gravity movement in various readiness position. tone and light stimulus, and various reaction method. The 33 male ball players, 30 female ball players, 42 female non-players, 35 male non-players, from colleges in the City of Seoul were taken as subjects. A reaction board with a electric automatic switch. T.K.K. made "Digital Timer" Chrono -scope and pistol or light bulb were used as a signal stimulus for this study. They stand on the board in knee bent position or Fundamental standing position, and in desingnated jump quickly to signal of pistol or light bulb. The results were as follows; 1. In reaction tine through 12 different methods of reaction. 1) College male players fastest. 2) Then the college female players comes in second. 3) Third. college male non-players. 4) Latest were the college female nolle-players. 2. In reaction speed between kneebent position and fundamental standing position. knee bent position is on an average 0.029/sec, faster than fundamental standing position in tendency. 3. In reaction speed between tone and light stimulus. The tone is on an averave 0.007/sec, faster than light stimulus in tendency. 4. In reaction speed between methods of reaction. 1) Straddle jump is fastest, vertical jump second, side jump is slowest within various readiness position and stimulus. 5. In reaction speed between male and female. Male is on an average 0.044/sec, fater than female in tendency. In conclusion, it can be summarized that the speed of reaction may be reduced into shortening of time by training.
