The purpose of this study is to examine anaerobid exercise capacity in runners. the number of experimental subjects were twenty-one Korean national elite runners without any abnormality inthe cardiorespiratory function. They completed a continous multistage treadmill and bicycle ergometer exercise test designed to achive maximum oxygen uptake. Ventilatory threshold were determined indirectly from the first and second breaks in the plot of VE vs VO₂and computer program has been developed that models the ventilatory response to exercise using multisegment linear regression. As the results of this sutyd, conclusions were obtained as follows: The mrathoners and middle and long distance runners have more higher aerobic exercise power than the sprinters(P<0.01). But the sprinters have higer values for maximal oxygen deficit, recovery oxygen uptake nad excess postexercise oxygen consumption than the marathoners and long distance runners.(P<0.01) These results suggest that the maximal oxygen deficit and excess postexercise oxygen consumption(EPOC) are the best parameter ofr the evaluation of anaerobic exercise capacity inrunners.

A Comparative Analysis of Ventilatory threshold, Lactate threshold and Onset of Blood Lactate on Wingate test in high school athletes. Exercise Science, 9(2): 375-384, 2000. The purposes of this study were : (a) to assess aerobic exercise capacity in sprinters, middle- and long-distance runners; (b) to investigate relationships among variables; and (c) to use these data as an useful reference for exercise performance. Seven subjects were selected in each event. They performed graded incremental maximal exercise on treadmill and supramaximal exercise(Wingate test) on computerized bicycle ergometer for 30 seconds. The results of this study were the following ; There were significant differences among runners in maximal oxygen uptake(VO₂max), ventilatory threshold(VT), lactate threshold(LT), onset of blood lactate accumulation(OBLA), and duration time (p<0.01). In terms of exercise type, there were no significant differences between sprinters and middle/long distance runners were found in supramaximal exercise(p<0.05). The results supported previous finding related to the relationship between aerobic capacity and the exercise type. In addition, this study strongly suggested that aerobic capacity based upon event should be considered when we select runners.

트레드밀 운동이 고지방 식이 유도 비만 쥐의 골격근 인슐린 신호 경로에 미치는 영향

김혜영 ( Hye Young Kim ),우진희 ( Jin Hee Woo ),여남희 ( Nam Hwoh Yeo ),강성훈 ( Sung Hwun Kang ),신기옥 ( Ki Ok Shin ) 한국스포츠정책과학원(구 한국스포츠개발원) 2012 체육과학연구 Vol.23 No.3

이 연구는 고지방식이 유발 비만 쥐의 8주간 규칙적인 트레드밀 운동이 인슐린 신호 전달 경로인 IRS-1/PI3K/Akt 단백질 수준과 mTOR 경로인 mTOR/mTORC1/S6K1의 변화를 살펴보기 위하여 실시하였다. 실험동물은 4주령 sprague-dawley rat 수컷 24마리를 1주간의 적응기간을 둔 뒤, 15주간 고지방식이로 비만을 유도하였다. 실험 동물은 고지방식이군(OD, n=8), 고지방식이 훈련군(ODT, n=8), 정상식이군(ND, n=8)으로 분류하였다. 트레드밀 운동은 1~4주는 주 5회 40분간 실시하였으며, 5~8주는 주5회 60분간 실시하였다. 그 결과 IRS-1과 PI3K는 OD군이 ND와 ODT군에 비해 유의하게 낮게 나타났다(p<0.05). 그리고 mTOR와 S6K1은 OD군이 ND와 ODT군에 비해 유의한 차이가 나타났다(p<0.05). 따라서 고지방식이 비만 유발 쥐의 8주간 규칙적인 트레드밀 운동은 골격근의 인슐린 신호 경로인 IRS-1과 PI3K 단백질 수준 향상에 긍정적 영향을 주며, 또한 mTOR 경로에서 S6K1을 개선시키는 것으로 나타나, 인슐린 신호경로와 S6K1의 변화를 통해 인슐린 민감성의 향상을 가져온 것으로 사료된다. The purpose of the study is to investigate how regular treadmill exercise for 8 weeks affects on expression of insulin pathway (IRS-1/PI3K/Akt) which is crucial signaling pathway to modulate insulin homeostasis on skeletal muscle for obese rats induced by high fat diet for 14 weeks and what is the relation between insulin pathway and mTORC1-S6K1 (mTOR pathway) which controls insulin pathway. The subject of this study was 24 white male rats of Sprague-dawley and we induced them to be obesity by diet for 14 weeks with water after the environmental adaptation for a week. Animals were divided three groups which are obesity diet group (OD, n=8), obesity diet training (ODT, n=8) and normal diet group (ND, n=8). They performed treadmill exercise for 40 minute 5 times a week for 1 to 4 weeks. For 5 to 8 weeks, treadmill exercise was performed for 60 minute 5 times a week. As a result, IRS-1 and PI3K were significantly decreased in OD group compared with ND group and significantly increased in ODT group compared with OD group (p<0.05). Although p-Akt was not significantly change, it tended to support previous studies (p<0.05). Also, mTORC1 was not significantly changed among groups. But S6K1 was significantly decreased in OD group compared with ND group and increased in ODT group compared with OD group. Therefore, we concluded that regular treadmill exercise for 8 weeks increased IRS-1 and PI3K protein levels affected on positive insulin signaling pathway. Furthermore, not overexpression of mTORC1-S6K1 but leading the change of S6K1 caused differentiation of insulin signaling steps according to muscular fiber.
