본 연구는 비만과 노화가 동시에 유발된 흰쥐에서 12주간의 트레드밀 운동과 L-arginine의 투여가 복부지방량, GH, IGF-Ⅰ, somatostatin, fibrinogen, PAI-1에 미치는 영향을 관찰하고 이를 개선하는데 더욱 효과적인 방법을 제시하는데 그 목적이 있다. 이를 위해 단독 처치 군과 복합 처치 군으로 나누어 실험하여 그 효과를 비교, 분석한 결과 다음과 같은 결론을 얻었다. 1. 복부지방량은 통제집단에 비해 모든 집단에서 유의하게 감소하였다(p<0.01). 2. AG+EX, AG+LA+EX집단에서 통제집단에 비해 GH의 혈중 농도가 유의하게 높게 나타났다(p<0.1). 3. AG+EX, AG+LA+EX집단에서 통제집단에 비해 IGF-Ⅰ의 혈중 농도가 유의하게 증가하였다(p<0.01). The purpose of this study was to investigate the effect of exercise and/or L-arginine on abdominal fat, IGF-1 on GH/IGF-1 axis, fibrinogen, and PAI-1 in aged and obese rats. Male Sprague-Dawley rats were treated with a D-galactose aging inducing agent (50 mg/kg) given intraperitoneally for 12 weeks. Thirty-two male Sprague-Dawley rats were treated and divided into four groups: aging-high fat diet group (AG+HF), AG+HF with L-arginine intake group (AG+LA), AG+HF with exercise group (AG+EX), and AG+EX with L-arginine intake group (AG+LA+EX). The experimental rats underwent treadmill training (60 min/day, 6 days/week at 0% gradient) for 12 weeks. L-arginine was given orally (150 mg/kg/day) for 12 weeks. After the experiment, blood was collected from the left ventricle and abdominal fat was extracted. The results showed that GH was significantly increased in AG+EX and AG+AL+EX. IGF-1 was significantly increased in both the AG+AL+EX and AG+EX group (p<0.05), while fibrinogen and PAI-1 were not significantly different among the groups. Abdominal fat was significantly decreased in the AG+LA, AG+EX, and AG+LA+EX groups (p<0.05) compared with the AG+HF group. In conclusion, this study suggests that exercise alone or L-arginine alone or a combination not only increases the GH and IGF-1 concentration, but also decreases the abdominal fat mass.

The purpose of this study was to analyses the effect of massage on total work during high intensity intermittent isokinetic exercise on taekwondo players` knee. The subjects were places in 2 groups: experimental group (n=11) continued massage and control group(n=10). Muscle strength was evaluated by total work of the knee using isokinetic exercise machine(Cybex NORMTM 770, USA). This result of the study are as follow; 1) Hamstrign and quadriceps of control group and massage group decrease significantly total work as set time passes(p<0.001). 2) There is no significant between a control group and a massage group, so after the fatigue of Hamstring and quadriceps, two minutes massage during set time is no significant of maintain endurance strength. 3) FT muscle fiber working is construed as a decrease of total work 3set and 4set. A local massage massages do not maintain to endurance strength as high intensity intermittent isokinetic exercise, but massages encourage to recover fatigue after exercise.
