The purpose of this study was to find the criterion on threshold determination of growth hormone secretion after maximal exercise. The subjects selected for the experiment were composed of 21 male college students (7 endurance runner, 7 physical education students, 7 general students). They performed maximal exercise by way of treadmill(Bruce protocal methods). Blood samples were drawn from a catheter previously inserted in an antercubital vein, pre-exercise, and right after maximal exercise, 30, 60min recovery period. Serum concentration of growth hormone were measured by radioimmunoassay(RIA) methods. The analysis of data revealed the followed findings; In growth hormone, there were significant differences among three groups following after maximal exercise and recovery period. As a result of this experiments, Growth hormone was more significantly increased after maximal exercise and recovery in non-athletes group than endurance runner group. This result appeared to imply that the increase growth hormone in endurance runner group played any role in maintaining the steady mobilization of lipid instead of the low catecholamine and glucagon discovered in athletes group. on the other hand, sychological stress caused controlling the modification sourse which maintains homeostasis by increaseing the hormone level.

본 연구에서는 성장호르몬 대사에 관여하는 유산소 운동과 L-arginine에 대한 효과를 알아보기 위하여 고지방 식이 섭취로 유도된 비만 흰쥐에서 트레드밀 운동과 L-arginine (150 mg/kg) 투여가 체중, 식이섭취량, 성장호르몬, 그리고 복부비만에 미치는 영향을 관찰함으로써 비만에 대한 효과를 알아보고자 하였다. 본 연구의 대상은 6주령 된 Sprague-Dawley계 수컷 흰쥐 50마리를 구입하여 32마리를 무작위 추출하여, 지방이 전체 칼로리의 60%를 차지하는 고지방식이사료(high fat diet # D12492, Reserh Diets Inc., USA)를 섭취한 고지방식이군(high fat diet; HF)을 대조집단으로 하여 트레드밀 운동(EX)과 L-arginine 투여(LA)가 체중 및 지방대사에 미치는 영향을 알아보기 위하여 HF군(n=8), HF+EX군(n=8), HF+LA 섭취군(n=8) 및 HF+EX+LA 섭취군(n=8)의 각 4개 군으로 분류하여 12주간의 실험을 실시하였다. 체중의 변화와 식이섭취량은 사전, 4주, 8주, 12주를 측정하여, 집단 및 시기 간의 이원반복변량분석을 적용하였으며, 그룹별 성장호르몬 농도와 복부지방량 측정은 일원변량분석을 적용하였고, 사후검증으로 Tukey`s 테스트를 적용하였다. 통계적 유의수준은 5%를 기준으로 하였다. 식이섭취량에서는 각 실험집단의 차이가 없었으나, 체중은 트레드밀 운동집단과 L-arginine 투여집단 그리고 L-arginine 투여와 트레드밀 운동을 실시한 복합처치집단 모두 유의하게 감소하였다. 또한 복부지방 조직 무게에서도 트레드밀 운동집단과 L-arginine 투여와 트레드밀 운동을 병행한 복합처치집단에서 유의하게 감소하였다. 혈청 성장호르몬 농도는 대조집단에 비하여 트레드밀 운동집단과 L-arginine 투여집단 그리고 L-arginine 투여와 트레드밀 운동을 실시한 복합처치집단 모두에서 유의하게 증가하였다. 결론적으로 트레드밀 운동과 L-arginine 투여가 성장호르몬의 농도를 증가시키는 방법으로 체중 및 지질 대사에 영향을 미쳐 체지방 형성을 억제함으로써 항비만 효과를 나타낼 수 있을 것으로 사료된다. 또한 트레드밀 운동과 L-arginine 투여를 병행할 경우에 복부지방량에서 단독 투여군에 비하여 더 많은 감소를 보여 운동과 L-arginine 투여의 병행이 체지방 감소에 보다 긍정적으로 작용할 수 있을 것으로 사료된다. The aims of this investigation was to examine the anti-obesity effects of treadmill exercise and oral administration with L-arginine in the high-fat diet induced obestiy rats. It is to analysis changes in body weight, food intake, abdomianl fat and growth hormone. Experimental rats were divided into 4 different experimental groups incluing an HF (high fat control; n=8), HF+LA (high fat+L-arginine oral administration; n=8), HF+EX (high fat+treadmill exercise), and HF+LA+EX (high fat+L-arginine oral administration+tredmill exercise; n=8). Rats were fed experimental diets supplemented with L-arginine at the level of 150 mg/kg/day for 4 weeks. Rats of HF+EX group and HF+LA+EX group performed tredmill exercise training at 60 min/day for 12 weeks. The body weight and abdominal fat mass were significantly decreased in HF+LA, HF+EX, and HF+LA+EX compared with HF group despite that food intake was not differed amone the experimental groups. However, The plasma growth hormone was significantly increased in HF+LA, HF+EX, and HF+LA+EX compared with HF group. These results suggested that the L-arginine oral administration and the regular aerobic exercise made the increase of anti-obesity effect in high-fat diet induced obesity rats.

1. The time of break point between Fast-component and slow component of O₂ up-take curve was presented at 12sec after recovery and its level of % VO₂max showed 32.18% VO₂max(Incremental) and 32.98% VO₂max(Continuous). 2. There were no significant differences of the break point between Incremental load and continuous load during recovery time. By above results, Though it was suggested that there will no problem for select any kind load exercise to evaluate O₂Debt during recovery time, but it shall be more desirable that Incremental load be applied to aged or women subjects and continuous load be applied to athletes or healthy subjects. To examine the level of % VO₂max which points the break point between Fast component and slow component by analyzing V E, VO₂, and LA concentration during recovery period after two kinds of treadmill exercise, 10healthy men(32.3%±4.72yrs) were tested as subjects. The methods of exercise load were Incremental load(start with 1.5mph, increasing the speed of 1.1mph at every 2min) and continuous load(continual running with the speed of 100% VO₂max level) with fixed 6% grade of treadmill. Results from the two kinds of load exercise are follows ;

This study aimed to determine the effect of 6 weeks plyometric training (PT) on agility, vertical jump and isokinetic leg strength in korea ROTC (Reserve Officers' Training Corps) cadets. Subjects were divided into two groups, a plyometric training (N=12) and a control group (N=12). The plyometric training group performed in a eight weeks plyometric training program((i.e., jumping, hopping, sprint, bounding) and the control group did not perform any plyometric training techniques. Plyometric were performed twice a week for 6 weeks. A pre and post test was conducted to measure alility, vertical jump(VJ), and isokinetic leg strength(knee extention, knee flexion). After 6 weeks plyometric training, the maximal isokinetic strength of the knee extensors and flexors significantly increased (p<0.05) compare to control group. The results showed that the agility significantly decreased (p<0.05) in plyometric training group compare to control group. But the vertical jump significantly increased (p<0.05) in plyometric training group compare to control group. It was concluded that plyometric training can not only improve agility and vertical jump performance but also enhance isokinetic leg strength in korea ROTC cadets.

The objective of this study is to clarify relationship between male middle school students' basic physical ability and their fat rate in their body. The test for the students' physical ability consists of 50M sprint, arm-bending, sit-up, standing long jump, trunk flextion sitting down and long race. The measured parts in their body are the abdomen, arm, thigh, and calf. For the result analysis, the simple regression analysis is used. Therefore, the result of this study suggests the following conclusions.1. 50M sprint shows a meaningful relationship with the weights excluding the total fat rate and the weights including the total fat rate.2. Arm-bending doesn't have a meaningful relationship with the weights excluding the total fat rate and the weights including the total fat rate.3. Sit-up doesn't have a meaningful relationship with the weights excluding the total fat rate and the weights including the total fat rate.4.

Wingate test 및 Supramaximal exercise를 이용한 무산소성 운동능력의 측정시 나타난 변인의 관련성을 살펴본 본 연구를 요약하면 다음과 같다. Wingate test시 혈중젖산농도 최고치는 9.04±0.62mM로서 Supramaximal exercise시 보다 유의하게 높았으며, 혈장 LDH 및 CPK활성도는 두가지 운동부하후 모두 유의한 변화는 나타나지 않았다. 근전도상의 적분치, 중간파형빈도 및 평균파형빈도도 유의한 변화는 없었다. 등속성 수축시의 최대토오크는 양쪽 다리 모두에서 초당 60도의 각속도에서가장 높았다. Wingate test시의 최대파워는 등속성 수축시 최대토오크 및 Wingate test시 중간파형빈도의 직접적인 영향을 받는 것으로 나타났으며, 평균파워는 Wingate test시의 적분치 변화, 듣는 쪽 슬관절의 등속성 수축시최대토오크 및 Supramaximal exercise시 혈장 LDH 활성도의 직접적인 영향을 받는 것으로 나타났다. 이상의 결과에서 무산소성 운동능력과 관련지어 그 기전을 살피고자 할 때 체내 화학적 변화, 전기생리적 변화 및 발현능력의 복합성을 고려해야 하며 최대누적 산소결핍량의 활용가능성은 측정강도 결정방법을 중심으로한 계속적인 연구가 요구된다. The present study examined the relationship of variables related to anaerobic capacity with Wingate test and supramaximal exercise. Peak value of blood lactate concentration with Wingate test showeda significantly higher than suprammaximal exercise, and plasma LDH & median power frequency and mean power frequency were not any difference between two tests. Peak torque of isokinetic contractionh on knee joint showed a highest value in 60 degrees of angular velocity among a various angular velocity. Peak power of Wingate test was related to peak torque of isokinetic contraction and median power frequency of EMG with Wingate test, and mean power of Wingate test was related to integrated EMG with Wingate test, peak torque with isokinetic contraction of dominant knee joint and plasma LDH activity with supramaximal exercise. In this result, when it analyzed the mechanism of anaerobic capacity, ti was required the consideration of complexity according to biochemical alteration, electrophysiological alteration and revelation of performance, Appicapability of maximal accumulated O₂deficit was demaned a continuous study with the focus of exercise intensity.

The aim of present study was to investigate the effect of exercise and/or L-arginine on Insulin growth factor-Ⅰ(IGF-Ⅰ) and lipid profile in high fat induced obese rat. For our experiment, male Sprague-Dawley rats (n = 32) at age 6 weeks were divided into four groups as follows: (1) High fat diet (HF), (2) HF with Exercise (EX), (3) HF with Arginine injection (ARG), (4) HF with EX + ARG (EX + ARG). The groups performed the training program for 12 weeks. After the program, blood was collected from left ventricle for analysis. As a result of analysis, IGF-Ⅰ was significantly increased in both EX + ARG and ARG (p < .05)while IGF binding protein (IGFBP) was not significantly different among the groups. Total cholesterol (TC) and LDL-C were significantly decreased in EX + ARG and EX (p < .05). In conclusion, this study suggests that combination of regular aerobic exercise and L-arginine consumption might prevent cardiovascular disease by increasing IGF-Ⅰ and decreasing TC and LDL-C.
