The purpose of this study was to investigate effects of inclination treadmill training on gait and gross motor function in children with developmental delay. In this study, a total of 12 developmental delay children was randomly assigned to: the 10° inclination treadmill training group, the 0° inclination treadmill training group. GMFM and K-PBS were used to evaluate the subject’s to gross motor function. In order to evaluate the subject’s walking ability, a walking analysis was conducted via GAITRite system. The intervention was performed 3 times a week for 3 weeks. Each session lasted 20 minutes. The experimental group conducted 10° inclination treadmill training, and the control group conducted 0° inclination treadmill training. The results of this study confirmed that 10° inclination treadmill training was effective in improving gait and gross motor function in developmental delay children. Therefore, 10° inclination treadmill training can be used as an effective interventional method in physical therapy developmental delay to improve gait and gross motor function in children with developmental delay.

The purpose of this study was to evaluation the effects of 16 weeks treadmill exercise program participation on endothelial function and plasma ferritin levels in adolescent smokers. Thirty-three adolescent smokers were randomly assigned to control groups(CG, N=17), treadmill exercise groups(EG, N=16). treadmill exercise was performed 4 times a week at the intensity of 50-80% HHR(1-4 weeks; 50% HRR, 5-8 weeks; 60% HRR, 9-12 weeks; 70% HRR and 13-16 weeks; 80% HRR). Endothelial Function, as defined by flow-mediated Vasodilation (FMD) of the brachial artery, and serum corboxyhemoglobin (COHb) were determined at pre exercise and at post exercise. The data from this study were analyzed using repeated measures two-way ANOVA. The following conclusions were obtained by comparing and analyzing the measurement value pre and post of 16 weeks exercise. In the changes of FMD, blood ferritin and COHb levels the exercise group was significantly improved more than control group and pre exercise data(p<.05). In conclusion, regularly aerobic exercise was effective in increasing endothelial function and reducing blood ferritin levels with COHb levels in adolescent smokers.

본 연구는 장기간 전신지구력 훈련 및 근지구력 훈련에 따른 흰쥐의 체중, 혈청 LDH 활성도, 혈청 LDH 동위효소, 혈청 CPK 활성도 변화를 관찰하기 위하여 전신지구력 훈련집단(n=12), 근지구력 훈련집단(n=12), 비 훈련 집단(n=12), 총 36마리를 대상으로 전신지구력 훈련 및 근지구력 훈련을 12주 동안 실시하여 훈련 4주, 8주 그리고 12주 후의 기간별 체중의 변화, 혈청 LDH 활성도, 혈청 LDH 동위효소, 혈청 CPK 활성도 변화를 생화학적으로 분석한 결과 다음과 같은 결론을 얻었다.1. 체중에 대한 기간 경과별 변화는 전신지구력 훈련집단은 유의한 감소를, 비훈련 집단은 우의한 증가를 나타냈으며, 전 집단간 차이는 4주, 8주, 12주에 유의한 차이를 나타냈다.2. 혈청 LDH 활성도에 대한 기간 경과별 변화는 전 집단에 걸쳐서 유의한 증가가 나타나지 않았다.3. 혈청 LDH<sub>1+2</sub> 동위효소 분포에 대한 기간 경과별 변화는 전 집단간 처치효과 기간효과의 두 가지 주 효과가 유의하게 나타났다. 집단간 차이는 8주, 12주에 유의한 증가를 나타냈다.4. 혈청 LDH<sub>3+4+5</sub> 동위효소분포에 대한 시간 경과별 변화는 집단간 처치 효과 기간효과의 두 가지 주 효과가 유의하게 나타났으며, 집단간 차이는 8주, 12주에 유의한 감소를 나타냈다.5. 혈청 CPK 활성도에 대한 기간경과별 변화는 집단간 처치효과 기간 효과의 두 가지 주 효과가 유의하게 나타났다. 집단간 차이는 8주, 12주에 유의한 증가를 나타냈다.이상의 결과를 종합해 볼 때 12주간의 전신지구력 훈련 및 근지구력 훈련에 따라 혈청 LDH 활성도, LDH<sub>1+2</sub> 동위효소 증가 수준은 심근에서 보다 근육에서의 스트레스가 장기간 지속되어 효소 유출이 주로 근육에서 발생되며, 효소의 유출기전으로써 세포막 투과성의 변화가 중요한 요인으로 작용하는 것으로 생각된다. 따라서 LDH<sub>1+2</sub> 동위효소와 혈청 CPK 활성도는 트레이닝 효과를 판단하는 지표로써 이용될 수 있는 가능성을 시사하고 있다. The purpose of this study was to observe the possible change of body weight, serum LDH activity, serum LDH isozyme distribution, and serum CPK activity of rats according to prolonged endurance training and muscular endurance training. 36 Sprague- Dawley rats were assinged to control. : 12 rats were by endurance training and 12 rats by muscular endurance training for 12 weeks, and 12 rats are not exercised(non-exercise group). After 4 weeks, 8 weeks, and 12 weeks training period, rats were biochemically analyzed by the change of body weight, serum LDH activity, serum LDH isozyme distribution and serum CPK activity. The analysis of data and findings are summerized as follows.1. The endurance training group revealed significant decrease and non-exercise group revealed significant increase in the change of body weight according to training period. And significant differences among three groups were found after 4 week, 8 week, and 12 weeks.2. Three groups revealed no significant increase in serum LDH activity during the change of training period.3. The change according to training period in serum LDH<sub>1+2</sub> isozyme distribution revealed two important effects significantly among all groups, such as prescription effect and period effect. The differences among groups revealed significant increase after 8 weeks and 12 weeks.4. The change according to training period in serum LDH<sub>3+4+5</sub> isozyme distribution revealed two important effects significantly among all groups, such as prescription effect and period effect. The difference among groups revealed significant decrease after 8 weeks and 12 weeks.5. The change according to training period in serum CPK activity revealed two important effects significantly among all groups, such as prescription effect and period effect. The differences among groups revealed significant increase after 8 weeks and 12 weeks.These findings suggest that prolonged training program on rats effluxs enzyme mainly in skeletal muscle. And skeletal muscles mainly contribute increasing the level of serum total enzyme activity, because skeletal muscle is much sensitive in physiological stress than heart muscle. Therefore, the findings of this study imply that sewn LDH<sub>1+2</sub> isozyme and serum CPK activity as a reliable criteria which determines the effects of training are used basic data for the improvement of athletic contests.
