The purpose of this study was to identify effects of an aquatic therapy program on patients with anterior cruciate ligament injuries. All of the patients responded to notices containing a description of the study that were posted in the rehabilitation center where the study were conducted. Participants registered for the program in the rehabilitation center, obtained physician`s permission to participated, and completed required registration forms. 16 participants were randomly assigned into two groups: an aquatic therapy program group(N 8), a physical therapy group(N 8). All of the participants completed the exercise during one hour a day, three days a week for 12 weeks. The following results were found in the study: 1. Changes of extensor and flexor at 60°/sec Although no significant difference was found between two groups, an aquatic therapy group and a physical therapy group with respect to the measures of peak torque, there were significant increases between two groups over training time. While there progressively increases between two groups with respect to the measures of peak torque on the uninvolved side at 60°/sec, there was not found significant difference between two groups over training time. No significants difference was found in both involved side and uninvolved side by the training period. The training group showed a quick recovery fro m the muscle functions, followed by a aquatic therapy group. This study also revealed significant differences training period X both involved and uninvolved side X group interaction. 2. Changes of extensor and flexor at 180°/sec in % body weight in the peak torque % body weight of extensor and flexor at 180° /sec, no significant difference was found between two groups. No significants difference was found in both involved side and uninvolved side by the training period. The training group showed a quick recovery from the muscle functions, followed by a aquatic therapy group. This study also revealed significant differences training period X both involved and uninvolved side X group interaction. in summary, as a result of 12weeks of rehabilitation program, there were differences between two muscular functions, while not significantly different from each other. This was showed differences in the muscular functions of both involved and uninvolved side between two groups by the treatment period. Although aquatic therapy group showed a quick recovery from the muscular functions, followed by physical therapy group, there was no significant difference.

The purpose of this study was to analyze and compare the feature of sports injuries of growth period the youth volleyball players and to provide the basic information for prevention of sports injuries. A total of 286 (male, 176, female, 110) questionnaires were distributed to high school volleyball players. Each questionnaires consisted of the cause and occurrence of sports injuries, injury type, and the location of the body that the injury affected. Chi square analysis was conducted using SPSS 18.0 for windows. The results showed that there was a significant difference between male and female volleyball players in back and foot injuries(p<.05), but no difference was found in head, neck, chest, arms, and legs. The most frequently occurred injuries were in the muscle and tendon for both gender(p<.05). The reason why most volleyball players injured was due to their carelessness during workouts. After being injured, there was a significant difference between gender in first aid and therapeutic period. It is important for high school volleyball players to realize that a certain level of physical fitness and technique are needed to avoid sport injuries. However, most volleyball players do not perform fitness training, so participants will always be exposed to the risk of the injuries. Coaches should approach to the program which include a variety of physical training to enhance and maintain athletes`s health.

The purpose of this study was to find out the effects of participation in small group exercise activity programs(22 weeks) on the development of physical fitness and the social adaptive behavior of mentally retarded students. The subjects were 5 mentally retarded students of high school for special education. KISE Developmental Scale(1996) by Korean Institute for Special Education were administered by specialized teachers of the students. The statistical procedures used to analyze the hypotheses were paired t-test. The major findings were as followings; 1) After the small group exercise, grip strength, back muscle strength and agility were increased, and then the whole body reaction time, rest heart rate and percent body fat were decreased. 2) After the small group exercise, the level of the development of self-support ability, social-emotional behavior, speech ability, cognitive ability, gross & fine motor skill were improved. 3) With respect to correlation of the physical fitness level and social adaptive behavior, percent body fat showed significant positive correlation with gross motor skill, and the flexibility showed significant positive correlation with self-support ability and cognitive ability, but negative correlation with gross motor skill. And agility showed significant positive correlation with cognitive ability, fine motor skill, but negative correlation with social-emotional behavior and speech ability. It could be concluded in this study that participation in small group exercise activity had significant effects on the development of the physical fitness and the social adaptive behaviors of mentally retarded adolescents. Considering the above positive effects, exercise therapy for mentally retarded persons was very effective in improving their fitness, leading to mental rest and increasing social ability, so it could be considered as one of effective ways for the rehabilitation and the treatment of mentally retarded persons.

This study was to find out the impact of regular Taegwondo exercise on the body composition and physical strengths in the elementary school children. Performing Taekwondo exercise program in the two groups, A group currently on Taekwondo lesson (N=30) and B group without experience of Taekwondo lesson (N=30), we reviewed the changes of variables on the body organization and physical strengths before and after Taegwondo exercise. With respect to the variables on the body composition between the groups before and after Taegwondo exercise, A group showed the significant differences in body weight (p<.003), amount of skeletal muscle (p<.029), and B group showed in amount of skeletal muscle (<p.034). In addition, inter-group differences were detected before the program in body weight (p=.012), amount of body fat (p=.004), and BMI (p=.004), and after the program in body weight (p=.014), amount of body fat (p=.003), and BMI (p=.007), significantly. For the study on the inter-group variables in the physical strengths before and after Taegwondo exercise, A group showed the significant differences in muscle strength (p<.000), muscle endurance (p<.000), flexibility (p<.000), quickness (p<.000), reflexes (p<.000), and heart and lung endurance (p<.000), and B group did in muscle strength (p<.000), muscle endurance (p<.000), flexibility (p<.000), quickness (p<.000), reflexes (p<.000), and heart and lung endurance (p<.000). Also, no significant difference statistically was detected between the groups before and after the program. Upon these results, Taegwondo exercise affected to the variables on the body organization including body weight, amount of skeletal muscle. It affected to the variables on the physical strengths including muscle strength, muscle endurance, flexibility, quickness, reflexes, and heart and lung endurance in both groups, significantly, too. For the duration of the exercise period by frequency, body weight and BMI showed the significant differences. For the occupation by frequency, body fat rate and abdominal fat rate did the significant differences. For the sex by frequency, abdominal fat rate did the significant difference. On the other hand, no significant difference was detected by frequency. Therefore, we think we can provide a lot of information on the changes of the body organization and improvement of variables in the physical strengths in the elementary school children if we investigate their diet habit, life style, and environment to develop the programs together with exercise therapy in further studies.
