        This study investigated exercise-related differences in reaction time with respect to whole body, pre-motor time, and also with respect to consequence of leg muscle contraction time in college soccer players(n=14) and general students(n=15), using electromyogram(EMG) system. All subjects were asked to response after the stimulus signal as quickly as possible with the specified stimulus-response by stepping off board which was equipped with sensor of time measurement. During the test, they were attacked by EMG electrodes on their spinal muscle(erector spinae) and leg muscles (rectos femoris, biceps femoris, tibialis anterior, gastrocnemius), In order to analyze the data of reaction times and consequence of muscle contraction time, mean and standard deviation of response time were calculated, and independent samples t-test was used. This study resulted in as follows: First, the soccer players were significantly faster than the general students on whole body reaction time(p〈0.001); second, the soccer players were significantly faster than the general students on pre-motor time(p〈0.05); third, the soccer players' muscle contraction time were significantly faster than the general students' muscle contraction time on rectus femoris, biceps femoris, tibialis anterior, gastrocnemius, but not erector spinae; finally, the consequence of Leg muscle contraction in soccer players was different from that in general students. It was found that although natural trait of reaction time is not controlled by experimental design of this study, long-term exercise with soccer is influenced on the whole body reaction time and each muscle reaction time, and consequence of muscle contraction time with the specific stimulus.

      • 學生 運動競技大會의 運營에 關한 考察 : 高校를 中心으로

        In order to present a normal and reasonable operating system of the interscholastic athletics being operated ineffectviely, In analyzed the true operating state of the current Korean interscholastic athletics of high schools by referring to the operating state of the interschoiastic athletics of the Indiana high-school athletic league. Therefore, the result of this study showed the followings: 1. The Indiana High School Athletic Association(IHSAA) organizes all formal competitions among high school memberships recognized from a principal and supervises the match directly. It also operates the game season of all events and limits strictly the game frequency of a regular season, the distance between schools. 2. The highschool interscholastic athletics program shows also the same phenomenon, especially in the case of a popular event, which is transmuting into the interscholastic game to get college entrance requirements for the students having a special talent. In addition, since the Korean highschools interscholastic athletics is managing Somewhat ineffctively, I would suggest several ideas to improve the management of interscholastic athletics for high-schools: First, there should be the balance of a match frequency for every team. Second, there should be a change from a typical tournament style to the "Home and Away" style. Third, there should be an activation on holding periodical tournaments among high school basketball clubs. Fourth, there should be an obligation on accepting an athletic club's expert coach system. Fifth, there should be a qualification standard for the student athlete's records in school. Sixth, there should be an obligation on the submitting of a certificate of health to protect an athlete for participating in a sport event. Seventh, there should be an unique organization for managing interscholastic athletics for the high-schools. Finally, there Should be a coordination system with mass media for activating interscholastic athletics.

        The purpose of this study was to examine the effect of regular physical activity on the quality of life in the aged. The subject(69.22±6.43) in the study consisted of two group, one group(*****(p.68)=27) was regularly participating in physical activities, and the other group(*****(p.68)=25) was non-physical activity. This study used two questionaires: one for mental health(obsession, somatization, anxiety, interpersonal sensitivity, depression, hostility, phobic anxiety, paranoid ideation, psychotism) and the other one for life satisfactory(life satisfaction, happiness, morale). The subjects were completed the questionaires of mental health and life satisfaction before and after the 12 weeks. While physical activity group participated in the exercise program for 12 weeks, the other group didn't any physical activity. This study used SPSS package in processing data and found the mean and standard deviation, depending on each factor to analyze data ANOVA. The results of this study were as follows: First, there was a significant difference in obsession, somatization, anxiety, depression, hostility, phobic anxiety between physical activity group and non-physical activity group, except for interpersonal sensitivity, paranoid ideation, psychotism. Secoed, there was a significant difference in life satisfaction between physical activity group and non-physical activity group. It means that participation in physical activity is related to increase of life-satisfaction. Therefore, in order to have quality of life, the aged should be encouraged to participate in physical activities regularly because of the possibility of increased mental health and life satisfaction.

        The pupose of this study investigated with using a hand-grip strength dynamometer and a back strength dynamometer by selecting of random sampling 10 members of middle school students so that biorhythm may know how to effect in the factor of muscle strengths (Grip strength, Back Strength, leg Strength). They measured the 3 times of every each rhythm in the maximum day of high cycle and the minimum day low cycle, the critical day, and the result is a follows: 1. The Change of record according to the rhythm of each individuality showed differently from each individuality. 2. When the physical rhvthm of each item is the maximum day the ance showed without the significant difference in P>0.05. 3. When each item is the maximum day in the cycle sum to each rhythm, the record showed higher than the minimum day and the critical day, but the effect of Analysis of VAriance showed without the significant difference in P>0.05. 4. In the rhythmical sum to each cycle, the physical rhythm of each item showed higher than that of emational rhythm and intellectual rhythm, but the effect of Analysis of Variance showed without the significant difference in P>0.05. Therefore the gap of record had according to rhythm and the cycle form but the effect of showed without the significant difference, so biorhythm showed that it didn't after influence in the muscular strengths.
