The purpose of this study was to demonstrate the effectiveness of functional soap(isporte) on the variables of body composition in 71 young men. For the purpose, we made the subjects 4 groups. The G1 included by an exercised group using in soups, G2 represented an only exercised group without using in soups, G3 represented a non-exercised group using in only soups, and then G4(control group) represented a non-exercised group without using in soups respectively. All the measured data were represented by mean and standard deviation(SD) using SPSS package(version 10.0). The statistical techniques for data analysis were used by two-way(4×2) repeated measured ANOVA. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. In results, the statistically different variables of the body composition were body weight, fat mass, % fat, WHR and obesity degree after 8 weeks. As a conclusion of these results, we could know that if the athletes used in isporte and participated in sports, they could have the improved body composition.

The purpose of this study was to demonstrate the effectiveness of Taekwondo training levels on the variables of bone mineral density and body composition in 24 young men(experimental group) compared with 8 young men(control group), who didn't experience the Taekwondo. For the purpose, making the experimental group separated by 3 groups(E3: 3poom, E2: 2poom, E1: 1poom) and the control group(C) respectively. All the measured data were represented by mean and standard deviation(SD) using SPSS package(version 10.0). The statistical techniques for data analysis were used by one way ANOVA. And then we performed scheffe post-hoc method for investigating exactly the differences between groups. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. The results of the study are as followed: At first, the statistically different variables of the bone mineral density were leg level(E3 & E1 group; E3 & C group), trunk level(E3 & E1 group; E3 & C group), spine level(E3 & E1 group), calcium level(E3 & E1 group; E3 & C group), and bone mineral content(E3 & E1 group; E3 & C group). At second, the statistically different variable of the body composition was a muscle mass(E3 & E1 group; E3 & C group), meaning that the E3 Taekwondo group, has been trained for a long time, was superior to the other three groups. As a conclusion of these results, we could know that if the young men performed the Taekwondo training for a long time, more or less 3 years, they could have the improved body composition.

본 연구는 유도선수들(실험군)과 일반인들(비교군)의 운동 전 60분, 운동 직후, 회복기 60분의 채혈 시점에서 혈장 항산화 효소활동과 MDA의 변화를 비교 분석하였다. 12명(실험군: 6명, 비교군: 6명)의 피험자를 대상으로 Bruce 프로토콜을 이용하여 더 이상 운동을 할 수 없는 최대시점의 운동강도까지 트레드밀에서 점증운동부하검사를 실시하였다. 이에 따라 탈진운동 전·직후·회복기에 나타나는 혈장 항산화 효소(SOD, CAT, GPX)수준과 MDA수준을 비교·분석한 결과 다음과 같은 결론을 얻었다.1) SOD는 탈진운동 직후 집단간에 통계적으로 유의한(p< .01) 차이를 나타내었으나, 운동 전과 회복기에는 유의한(p >.05) 차이를 나타내지 않았다.2) CAT는 탈진운동 직후 집단간에 통계적으로 유의한(p< .05) 차이를 나타내었으나, 운동 전과 회복기에는 유의한(p >.05) 차이를 나타내지 않았다.3) GPX는 탈진운동 직후 집단간에 통계적으로 유의한(p< .05) 차이를 나타내었으나, 운동 전과 회복기에는 유의한(p >.05) 차이를 나타내지 않았다.4) MDA는 탈진운동 직후 집단간에 통계적으로 유의한(p< .05) 차이를 나타내었으나, 운동 전과 회복기에는 유의한(p >.05) 차이를 나타내지 않았다.본 연구 결과에서 탈진운동 후 유도선수들과 일반인의 항산화 효소(SOD, CAT, GPX)수준과 과산화지질의 일종인 MDA는 영향을 받는데, 특히 탈진운동 직후에 유도선수집단의 항산화 효소 및 MDA수준은 일반인들보다 통계적으로 유의한 증가를 보였는데, 이는 탈진운동이 산화적 손상을 크게 하지만 규칙적인 훈련으로 인하여 산화적 손상에 대한 방어능력도 향상된 것으로 생각된다. The purpose of this study was to investigate the antioxidant enzymes(SOD, CAT, GPX) activity and lipid peroxidation`s level(MDA) of Judo athletes who training regularly. To achieve the purpose, Twelve healthy young males(Judo: 6, Control: 6) were recruited for this study. Blood samples were collected at pre-exercise 60 minutes, post-exercise and recovery 60 minutes in which all subjects carried on maximal all-out exercise in treadmill.The analysis of data revealed as following:1) There were significant differences(p<.01) in the SOD level between two groups in post-exercise, but no significant differences in post-exercise and recovery 60 minutes.2) There were significant differences(p<.05) in the CAT level between two groups in post-exercise, but no significant differences in post-exercise and recovery 60 minutes.3) There were significant differences(p<.05) in the GPX level between two groups in post-exercise, but no significant differences in post-exercise and recovery 60 minutes.4) There were significant differences(p<.05) in the MDA level between two groups in post-exercise, but no significant differences in post-exercise and recovery 60 minutes.In conclusion, antioxidant enzymes` level(SOD, CAT, GPX) activity and lipid peroxidation`s level(MDA) of Judo athletes and control groups were affected by maximal all-out exercise. Especially, After maximal all-out exercise the antioxidant enzyme level and MDA level of Judo group was statistically higher than that of control group. It was revealed that Judo athletes were prone to injure by oxidative stress than control group. But we think they have stronger preventive system than that of control group.

본 연구의 목적은 ACL·PCL손상군 16명을 대상으로 60°/sec(근력)에서 최대회전력, 체중당 최대회전력과 최대발현각도를 180°/sec에서는 총일량과 체중당 총일량을 산출하였으며, 두 각속도에서 각각 근결함비와 근력비를 측정하여 분석하였다.1. 60°/sec에서 ACL손상군의 우측(환측)과 좌측(환측)의 신근 및 굴근의 최대회전력, 체중당 최대회전력은 유의한(p<.01) 차이가 있었으나, 최대발현 각도는 유의한(p<.05) 차이가 없었다. 또한 180°/sec에서 우측(환측) 신근의 총일량과 체중당 총일량도 유의한(p<.01) 차이가 있었고, 굴근에서는 유의한(p<.05) 차이가 없었다.2. 60°/sec에서 PCL손상군의 우측(환측)과 좌측(환측)의 신근 및 굴근의 최대회전력, 체중당 최대회전력은 각각 유의한(p<.05, p<.01) 차이가 있었으나, 최대발현 각도는 유의한(P<.05) 차이가 없었다. 또한 180°/sec에서 우측(환측) 신근 및 굴근의 총일량과 체중당 총일량은 유의한(p<.01) 차이를 나타내었다.3. 60°/sec에서 ACL손상군과 PCL손상군의 신근 및 굴근의 최대회전력은 유의한(p<.05) 차이가 없었으나, 체중당 최대회전력은 유의한(p<.01) 차이를 나타내었다. 그러나 두 집단에서 최대발현 각도는 유의한(p<.05) 차이를 나타내지 않았다.4. 180°/sec에서 ACL손상군과 PCL손상군의 신근 및 굴근의 총일량은 유의한(p<.05) 차이가 없었으나, 체중당 총일량은 유의한(p<.01) 차이를 나타내었다. 그러나 두 집단에서 최대발현 각도는 유의한(p<.05) 차이를 나타내지 않았다.5. 60°/sec에서 ACL손상군과 PCL손상군의 좌우측 다리의 신근 및 굴근의 최대회전력의 근결함비는 각각 유의한(p<.05, p<.01) 차이가 있었고, 180°/sec에서 두 집단의 신근의 총일량도 유의한(p<.01) 차이를 나타내었으나, 굴근의 총일량은 유의한(p<.05) 차이를 나타내지 않았다.6. 60°/sec에서 ACL손상군과 PCL손상군의 우측(환측)다리의 신근 및 굴근의 최대회전력의 근력비는 각각 유의한(p<.05) 차이가 없었고, 좌측(건측) 다리의 신근 및 굴근의 최대회전력의 근력비도 유의한(p<.05) 차이를 나타내지 않았다. 또한 180°/sec에서도 두 집단의 우측(환측) 다리의 총일량의 근력비는 유의한(p<.05) 차이를 나타내지 않았으며, 좌측(건측) 다리의 총일량도 유의한(p<.05) 차이를 나타내지 않았다.결론적으로 무릎의 슬관절은 복합관절로 근력이나 순발력을 발휘할 때는 구조적 손상의 차이로 인해 기능적 능력에 차이가 생기기 때문에 재활치료 프로그램을 구성할 때는 ACL손상과 PCL손상에 따라 다소 차이를 두는 것이 바람직하다. The purpose of this study was not only to investigate the peak torque, percentage of peak torque to body weight and angle of peak torque in 60°/sec(muscular strength) but also to the total work and percentage of total work to body weight in 180°/sec(muscular power) and then to DR(deficit ratio), HQR(hamstring/ quadricep ratio) in both angular velocity. Sixteen patients of anterior cruciate ligament injury and posterior cruciate ligament injury were tested by isokinetic machine, Cybex 770.1. In 60°/see the peak torque and percentage of peak torque to body weight of extensor and flexor in both right(ACL injury part) and left(normal part) legs of ACL group were significantly(p<.01) different, but angle of peak torque of this group was not significantly(p<.05) different. In 180°/sec the total work and percentage of total work to body weight of extensor in a right(ACL injury part) leg were significantly(p<.01) different, but the those of flexor in a right leg were not significantly(p<.05) different.2. In 60°/sec the peak torque and percentage of peak torque to body weight of extensor and flexor in both right(PCL injury part) and left(normal part) legs of PCL group were significantly(p<.05, p<.01) different, but angle of peak torque of this group was not significantly(p<.05) different. In 180°/sec the total work and percentage of total work to body weight of extensor and flexor in a right(PCL injury part) leg were significantly(p<.05) different.3. In 60°/sec the comparison result of the peak torque of extensor and flexor in ACL group and PCL group was not significantly(p<.05) different, but the percentage of peak torque to body weight in both groups was significantly(p<.01) different. And the angle of peak torque of these groups was not significantly(p<.05) different. 4. In 180°/sec the comparison result of the total work of extensor and flexor in ACL group and PCL group was not significantly(p<.05) different, but the percentage of total work to body weight in both groups was significantly(p<.01) different. And the angle of peak torque of these groups was not significantly(p<.05) different.5. In 60°/sec the comparison result of the peak torque deficit ratios(DR) of extensor and flexor of left and right legs in ACL group and PCL group were significantly(p<.05, p<.01) different. In 180°/sec the comparison result of the total work deficit ratios of extensor in ACL group and PCL group was significantly(p<.01) different, but the those of flexor in both groups were not significantly(p<.01) different.6. In 60°/sec the comparison result of the hamstring/ quadricep ratios(HQR) of extensor and flexor of a right(injury part) leg in ACL group and PCL group was not significantly(p<.05) different. The hamstring/ quadricep ratios(HQR) of extensor and flexor of left(normal part) legs in ACL group and PCL group was not significantly(p<.05) different. In 180。/sec the comparison result of the hamstring/ quadricep ratios(HQR) of extensor and flexor of a right(injury part) leg in ACL group and PCL group was not significantly(p<.05) different. The hamstring/ quadricep ratios(HQR) of extensor and flexor of a left(normal part) leg in ACL group and PCL group was not significantly(p<.05) different.As a conclusion, the knee joint has a complex and a lot of joint. When One performed strength and power, these abilities were different due to functional ability by a structural injury. So As we will compose the knee rehabilitation care program, we must think the differentiation of ACL and PCL injury.
