자연과학편 : 최대하 운동시 혈중젖산에 미치는 스트레스 호르몬 반응에 관한 연구

조정호(JungHoCho),김상복(SangBockKim),박정래(JeongRaePark) 한국체육학회 1992 한국체육학회지 Vol.31 No.2

본 연구는 대학 중장거리 육상선수들을 대상으로 최대하 운동시 (70~80% VO₂max) 반응하는 스트레스 호르몬들의 변화양상과 혈중젖산 이용에 스트레스 호르몬 대사활동이 미치는 영향을 규명하고자 시도되었다.운동전, 최대하 운동직후, 회복시등 세처치간에 있어서 Growth Hormone을 제외하고는 스트레스 호르몬들의 변화는 유의한 차(p<0.05)로 나타났다.스트레스 호르몬 유형들간에 있어서 운동전의 경우, 통계적으로 상관관계가 없는 것으로 나타났으나, 최대하 운동직후 및 회복시에 있어서는 스트레스 호르몬들의 상승작용(synergism)에 의하여 상관관계가 현저한 것으로 나타났다.운동전 혈중젖산에 Norepinephrine, Epinephrine등이 영향을 미치는 것 (p<0.05)으로 나타났고, 최대하 운동직후에는 통계적으로 유의하지 않았으며, 회복시 혈중젖산에 Growth Hormone, Cortisol, In-sulin등이 영향을 미치는 것(p<0.05)으로 나타났다.혈중 젖산 이용의 조절에 대사적 혹은 스트레스 호르몬 인자들이 관여하는 것에 대한 명확한 증거는 없으나 내생의 젖산생성을 억제하는 대사적, 스트레스 호르몬 인자들은 아마도 혈중젖산 이용을 원활하게 할 것이며 초성포도산염 탈수소효소의 활성화는 혈중젖산 이용을 증가시키며 유리지방산(FFA)과 같은 대체물질을 즉각적으로 사용할 수 있으면 혈중젖산 이용이 억제될 것으로 추정된다. 즉, 운동시 대사산물과 다른 화학적인 인자효과 뿐만 아니라 부분적으로 스트레스 호르몬 환경과 농도가 혈중젖산 이용을 결정하는데 중요한 역할을 하는 것으로 사료된다.

이지현(JiHyunLee),조정호(JungHoCho),신말연(MalRyunShin),최혜진(HeaGinChoi),최보인(BoInChoi),김희정(HeeJungKim) 한국체육학회 2006 한국체육학회지 Vol.45 No.2

본 연구는 유산소 운동수행 시 적정량의 carnitine을 섭취하였을 때 여자대학생의 체지방율, 혈중지질 및 leptin에 미치는 영향과 각 관찰변인들 간의 상관을 파악하여 안전한 보조제로서의 carnitine의 효능을 규명하고, 운동과 이상적인 신체조성에 필요한 실험적 자료를 제공하는데 연구의 목적이 있다. 여대생 21명으로 구성되었으며 이들을 완전 임의배열법에 의해 7명씩 세 집단으로 분류하였다. Group Ⅰ은 placebo 6g, group Ⅱ는 carnitine 3g+placebo 3g, group Ⅲ는 carnitine 6g을 6주간의 운동 시작 약 30분 전에 섭취하도록 하였다. 통계처리는 공변량 분석, 상관분석 및 회귀분석 등을 적용하여 분석하였다. 실험결과 그룹 간 모든 변인에서 유의한 차이가 나타나지 않았다. 6주간 최대6g의 carnitine 섭취 시 부작용은 관찰되지 않아 인체에는 안전한 것으로 인식되며, 여대생을 대상으로 한 보다 명확한 카르니틴의 효능을 규명하기 위해서 운동형태, carnitine 섭취량, 개개인의 트레이닝 상태 등을 고려한 다각적인 연구가 수반된다면 보다 긍정적인 변화를 기대할 수 있을 것으로 사료된다. The purpose of this study was to investigate the effects of carnitine supplementation with aerobic exercise on percent body fat, blood lipid, and leptin in college females. 21 college females were randomly assigned to one of three groups, i.e., GroupI(n=7):placebo(6g/day); GroupII(n=7):carnitine(3g/day)+placebo(3g/day); GroupIII(n=7):carnitine (6g/day) with aerobic exercise for 6 weeks. For aerobic exercise, they performed treadmill exercise(60-90%HRmax, 3-5d/w, 20-30min/d). Analysis of covariance, analysis of multiple correlation and analysis of simple regression were used to determine the statistical significance. There were no significant differences in percent body fat, blood lipid, and leptin. In conclusion, 6 week-experiment period might not be long enough to observe the effect of the carnitine supplementation on percent body fat, blood lipid, and leptin. In addition to extension of the experiment time, exercise types, carnitine dosage and training status of individuals are considered as the logical extension of the current research.

This study attempts to identify the effects of distance runners’ detraining on the serum lipid metabolism. To do this, the sample of 22 athletes are divided into three groups : the group without any change in their exercise and diet ; the group who stop exercise and reduce the intake of food: and the group who keep exercising but reduce the intake of food. These three groups are repeatedly compared and measured for twelve weeks to see cardiovascular organs and during exercise through different types of training, which leads to following conclusions.1. For twelve weeks, groups of Training I and Training II show the tendency of decreased serum Total Cholesterol and LDL-Cholesterol, while the group of Detraining revealed increased serum Total Cholesterol and LDL-Cholesterol. The differences among three groups appeared statistically significant at 0.05 level, but the differences between training periods and the interaction effects between the groups and the periods are not statistically significant.2. For twelve weeks, groups of Training I and Training II show the tendency of increased serum HDL-Cholesterol, while the group of Detraining revealed decreased serum HDL-Cholesterol, while the group of Detraining revealed decreased serum HDL-Cholesterol. The differences among three groups appeared statistically significant at 0.05 level, but the differences between training periods and the interaction effects between the groups and the periods are not statistically significant.3. For twelve weeks, groups of Training I and Training II show the tendency of decreased serum Triglycerides and TC/HDL-C Ratio, while the group of Detraining revealed increased serum Triglycerides and TC/HDL-C Ratio. The differences among three groups and the interaction effects between the groups and the periods appeared statistically significant at 0.05 level, but the differences between training periods are not statistically significant.4. These serum lipid lipoproteins which affect VO₂max are Total Cholesterol, HDL-Cholesterol and TC/HDL-C Ratio. (P<0.05)

The purpose of this study was to investigate the effects of megavitamin E supplementation on changes of serum components and cardiopulmonary Function.1. The subjects of this study were 30 Rugby Football players of high school. And they were randomly assigned to three groups as follows : Supplemental gorups were ingested 400IU/day and 1000IU/day of d-αtocopherol during 60 days. Control group was ingested Placebo during 60 days.2. The results were summarized as follows:1) The values of serum α-Tocopherol were significantly(P<0.05) increased in 1000IU group after 60days comparing to the pretreatment levels, And these were decreased after post treatment. But, this was not significant difference.2) The valves of serum Total Cholesterol were significantly(P<0.05) decreased in all groups after 60 days comparing to the pretreatment levels And. the values of serum HDL-C were significantly(P<0.05) increased in all groups after 60days comparing to the pretreatment levels. But, these results were not significant differences among three groups.3) The values of serum Triglyceride were decreased in all groups after 30days and 60days comparing to the pretreatment levels. And, these were increased in all groups after post-treatment. But. these results were not significant differences between treatment groups and dosing times.4) V˙O₂ max and All-out-time were significantly(P<0.05) increased in all groups after 60 days comparing to the pre treatment levels. And, these were decreased in all groups after post treatment. But, these results were not significant differences among 3 groups.5) V˙Emax was significantly(P<0.05) in creased in 1000IU group after 60 days. And, this was decreased in 1000IU group after post treatment. But, these results were not significantly differences between 400IU group and 1000IU group.6) HR at rest. HRmax. and RRmax were not significant differences between treatment groups and dosing times.In summary, serum HDL- Cholesterol was increased and V˙O₂max All-Out time. and V˙Emax were improved. But. these were not significant differences among treatment groups. And. the effects of training and psychological factor were not excepted in this study. Therefore. these results were unable to confirm the ergogenic effects of the megavitamin E to improve the cardiopulmonary function.
