        태권도 선수경력에 따른 유연성, 평형성, 하지길이 및 골반변위 지표의 비교 분석

        배기원(Bae Gi-Won),이원재(Lee Won-Jae),주성범(Ju Sung-Bum) 한국체육과학회 2008 한국체육과학회지 Vol.17 No.1

        The purpose of this study was to compare the flexibility, balance, leg length, index of pelvic deviation according to career of taekwondo players. Subjects were divided in to 3 group(control, taekwondo player of one-year career, taekwondo player of two-years career). Flexibility(sit & reach, trunk extension), Balance(closed eyes foot balance), Leg length inequality wasn't statistically significant according to career of taekwondo. Analysis of the index of pelvic deviation, ilium length, ilium width revealed that the taekwondo player of two-years career showed significantly higher than control group and sacral width(left) revealed that the taekwondo player of two-years career showed significantly higher than taekwondo player of one-year career. To conclude, More than two-years career of taekwondo players will be effectively appeared to pelvic deviation.

        흑마늘 섭취가 최대운동 후 혈중피로변인과 간기능에 미치는 영향

        This study wasperformed to review the effects of black garlic intake on exhaust variables, liver function enzymes of Taekwondoplayers at the maximal exercise. After 10 to 20 days’ black garlic intake, they were asked to do the exercise to the maximal level on the treadmill. Blood serum LDH, blood serum CPK, lactic acid in the blood, blood serum GPT and GOT were measured at the restperiod, immediately after exercise, 10 and 30 minutes in the recoveryperiod. The results are as follows: 1. Changes in Serum CPK Black garlic intake for 10 days made significantly low level of blood serum CPK comparing to the non-intake group at the maximal exercise. Black garlic intake for 20 days seems to restore blood serum CPK to the level at the resting state at 10 and 30 minutes in the recovery period. 2. Changes in Serum LDH Regarding the changes in Serum LDH in case of black garlic intake for 10 days, it were kept at the level of resting state even after the exercise, 10 and 30 minutes in the recovery period. When they take black garlic for 20 days, they restore serum LDH to the level at the resting state at 10 and 30 minutes in the recoveryperiod after the maximal exercise. 3. Changes in Blood Lactic Acid Regarding the changes in lactic acid in the blood in case of black garlic intake for 10 days, there was significant difference immediately after exercise, 1, 3, 10, 15 and 30 minutes in the recoveryperiod between the garlic intake group and non-intake group(p<.05). After the intake for 20 days, garlic intake group shows the level of lactic acid at the resting state. Conclusively, black garlic intake for 10 days can make significant difference in the level of lactic acid in the blood comparatively lower than that in non-intake group. 4. Changes in Blood Serum GOT and GPT In the changes in GOT and GPT according to the 10 days’ intake of black garlic, both groups showed significantly higher level comparing to that at the resting state(p<.05). When taking black garlic for 20 days, the garlic intake group showed significantly higher level at 10 and 30 minutes at the recoveryperiod(p<.05). Non-intake group showed significantly high level immediately after exercise comparing to that at the restingperiod(p<.05). From the above results, black garlic intake for 10 to 20 days seem to help the activation of serum CPK and LDH, recovery of lactic acid and the activation at the maximal level of exercise. Therefore we can expect to remove the fatigue factors in the blood by taking black garlic. However, we could not confirm the effects of black garlic intake on liver function enzymes. It may be because we select Taekwondoplayers as our subjects. Because of the characteristics of Taekwondo, the maximal exercise could not make significant influence on the relationship between the changes in liver function enzymes and garlic intake. Through this, it is considered that we need to have research on different subject groups and change the type of exercise. If we adjust the variables of intake value and intakeperiod with concrete and scientific ways, we may be able to identify more systematic and comprehensive effects of the garlic intake.
