This study was designed to estimate the physiological effects of dehydration and rehydration especially, the components of fluid intaked during exercise in heat environment. Subjects(N=40) who were intercollegiate athletes were randomly assigned to three groups, D(N=15) group, G(N=13)group, E(U=12) group. Each subjects performed ergometer exercise consisted of stage Ⅰ, Ⅱ and 5 min rest between both stages. The results through the statistical analysis of various data(blood analysis, performance indexes) were summarized as follows ; 1. Hemoconcentration progress during exercise was more effectively controlled in E group than any other group. 2. The results of analysis for the PV, MCV, Osm indicated that the difficulty in blood circulation resulted from evaporative fluid loss during exercise in heat could be alleviated by drin-king fluid containing the moderate amount of electrolytes. 3. The significant inhibiting effects on the secretion of PRA, PA appeared in fluid intaking groups, especially, E group. 4. Comparing to D group, more slow rise of temperature during exercise and more significant recovering tendency of H.R. tem. during 30-min rest appeared in both fluid intake groups, especially E group.

This study was designed to investigate the effects of long~term training on the lipid(triglyceride, cholesterol) and lipoprotein(HDL-cholesterol). The subjects consisted of 9 junior female athletes(exercise career, three month ; A group) and 6 athletes(exercise career fifteen month ; B group) and 12 junior school girls as control group(C group) who all were about thirteen years old. Both athlete groups(A, B group) were continuous to participate in six month training and their blood samples were collected at pre mid(after three month) and post(after six month). The control subjects donated their blood at pre and post(after six month). The collected blood were analyzed for the triglyceride, cholesterol, High density lipopro-tein cholesterol and HDL-C/TC ratio. The result through the statistical analysis of this data were summarized as follows The pre-levels of triglyceride and total cholesterol in Athlete group, especially Bgroup were lower than those in Non-athlete group(p<0.01). HDL-C level and HDL-C/TC ratio were highest in B group among three group(p<0.05). HDL-C level and HDL-C/TC ratio in both athlete group, especially A group were significantly decreased after three and six month(p<0.01) while in control group all item were not changed. The result indicated by three month training and the change of HDL-C need more long term training(more than three month).

This study was designed in order to assess the value of total serum LDH and the distribution of the serum LDH isoenzyme as the quantitative indicator of physical fitness level and exercise stress. The Soccer athletes and weight-lifting athletes was assigned from J university as subjects of this study, who were 18-23 years old. All subjects were asked to perform two types of ergometer exercise, one hour-aerobic and three minanaerobic exercise. The blood samples were collected from all subjects before and after exercise of two types and analyzed for total serum LDH and LDH isoenzyme distribution. The results of analysis on the data obtained from each measurment were as follows : 1. At rest, LDH-5 in weight lifting Group was significantly higher than in in Soccer Group and other LDH isoenzymes and total LDH showed no significant difference between two groups. 2. Total LDH and LDH-5 were significantly increased after anaerobic exercise(p<05), but there were no significant difference between two groups(Soccer and Weight-lifting group ). 3. LDH-1 was only significantly increased after aerobic exercise(p<05), but there was no significant difference between two groups, the other item showed no significant change after aerobic exercise. 4. Maximal Oxygen uptake and Lactate had no significant correlation with total LDH and LDH isoenzyme. This result shows that total serum LDH and LDH isoenzyme distribution are not appropriate as the indicators of cardio-respiratory endurance level or exercise stress.

This study was designed to examine the effect of exercise of increasing intensity on ammonia and lactate production in man and to relate these changes to blood concentration of lactate and ammonia during the maximal test. 10 normal healthy males served as subjects for this study. They were 32.4 years, 169.7 ㎝ in height, and 72.8 ㎏ in body weight. Incremental load aerobic power tests were performed by each subject on a Monark ergometer. During the test, Heart rate was monitored by three-lead electrocadiography. Blood was sampled from an antecubital vein using an indwelling cannula in the final minute of each grade. Results as follows: 1. Blood ammonia concentration increased from 86.9 to 213.5 ㎍/dl during the maximal exercise, while lactate accumulation increased from 1.9 mmol/1 to 11 mmol/l. 2. Relationship between lactate and ammonia accumulation pattern by the exercise intensity showed very high correlation coefficient(r=0.988, p>0.001) and linear relationship. 3. Regressional equation to explain between ammonia and lactate accumulation in blood revealed Y(Ammonia)= 28.4 + 16.6 X(Lactate).

The purpose of the present study was to determine whether Aspirin affects on cardiorespiratory responses of human after an eccentric bout. On two diffrent occations, each subject performed a graded maximal exercise test, using Bruce Protocol on a treadmill until all-out 48 hours following bech stepping (50㎝ step, 15 steps min^-1) for 30 min. Placebo or Aspirin (1000㎎)was administrated after each bench stepping, 4 times at an interval of 12 hours for 48 hours. The First tests and the second test were carried out 2 weeks apart and the exercise order of the subjects was randomized. For the first 15 min, the subjects used the right leg as the leading leg and then used the left leg as the leading leg for the remaining 15 min. Continous measurement of breath-by-breath ventilation, oxygen consumption, respiratory frequency, respiratory exchange ratio and heart rate were monitored throughout the maximal exercise test using a cardiopulmonary stress system. The analysis of all investigates variables, except for respiratory exchange ratio, showed statistically significant difference between before and aspirin administration after an eccentric exercise bout. Duration of maximal exercise decreased significantly after aspirin administration, suggesting that aspirin administration (1000㎎ of aspirin, four times for 48 hours) after an eccentric exercise bout affects physical performance during maximal exercise.

운동과 인삼의 뇌하수체-부신피질 축 호르몬의 활성화 작용

위승두,정일규 조선대학교 스포츠과학연구소 1991 스포츠科學硏究 Vol.4 No.-

인삼의 항 스트레스 작용기전은 HPA axis의 활성화를 통해 이루어 진다고 설명되고 있으며, 장기간의 운동 역시 HPA axis에 대한 반복적인 자극에 의해 부신비대 등 적응성 변화를 일으킨다고 보고되고 있다. 그러므로 인삼이 일종의 스트레서(stressor)로서 작용하는 운동에 의해 활성화되는 HPA axis 반응을 더욱 항진시킴으로써 인체에 가해지는 스트레스에 보다 효과적으로 대처하게 해준다는 개념이 성립될 수 있을 것이다. 그러나 이러한 개념의 검증에는 선결해야 할 몇가지 논점이 따르게 된다. 그것은 첫째, 운동훈련에 따른 특정부하강도에서의 HPA axis 호르몬 반응의 변화가 있는가? 둘째, 이들호르몬의 반응이 변화된다면 그것은 운동스트레스자체의 크기 변화에 따른 것인가? 아니면 그 스트레스에 대한 HPA axis 민감도의 변화에 의한 것인가? 셋째, 인삼 투여에 따른 HPA axis 활성화 작용은 운동스트레스 상황하에서도 마찬가지의 약리적 효과를 발휘하는가? 넷째, 인삼이 운동시 HPA axis 반응을 항진시킨다면, 그러한 항진된 반응은 수행력과 관련하여 어떠한 의미를 갖고 있는가? 이러한 논점에 대한 추후 많은 실험적 증거에 의해서 인삼의 항스트레스 작용 및 ergogenic aid로서의 가능성이 평가되기를 기대한다. The purpose of this article was to review and discuss the effect of HPA axis activation of ginseng related to exercise. Ginseng saponine has been reported to activate the HPA axis as well as exercise. Therefore, the concept can be estabilished that HPA axis activation effect of ginseng, probably, help athletes to improve their performance through an adaptation to exercise stress. But, there are some questions to be resolved in order to prove that concept. First, Can exercise training chang the response of HPA axis on the given relative load? Second, If the response were changed, is the change of response due to change of exercise stress itself, or the sensitivity of HPA axis to the stress? Third, Can ginseng administration take effect of HPA axis activation in exercise situation as well as rest? Last, What is the significance of HPA activation effect of ginseng in relation with performance? We hope that the anti-stress effect and posibility as an ergogenic aid of ginseng be evaluated by the future experimental study on this topic.
