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.

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).

The human physical activeity has been reduced by the developing scientific civilization, but nowadays people has a great interst in health and physical strength. They have studied how to keep their health in many ways. 1n this report I am going to compare the physical shape, function, and fitness of urbon people with those of rural people and study their corelation. First, I chose one hundred and fifty three persons at random from each group and examined the physical fitness reared by the exercise oh exercise group in the urban or the labor of farmer group in the rural, and then I have researched the corelation between the physical fitness and the characteristic of body. The conclusion of study is as follows; 1. The two groups are similar in the physical shape, but exercise group is a little superior in weight. 2. In the function of living body respiratory rate of exercise group is increased gradually as order. Pulse rate of exercise group is usually fixed, but that of farmer group is 72.3 times in thirties and 74.8 times in fifties. Systolic blood pressure of exercise group is 123-129 times and of farmer group 121-131 times. Distolic blood pressure of exercise group is 80-83 times and of farmer group 79-84 times. 3. Rohrer’s index of exercise group is decreased as older. That of farmer is increased in forties but decreased in fifties. 4. In physical fitness exercise group is superior in vertical jump, closed-eyes foot balance, and standing trunk flextion. Farmer group is superior in grip strength. Two groups are similar in side step and step side. 5. The measurements of side step, vertical jump, closed-eyes foot balance, and standing trunk flextion are dropped as older, especially closed-eyes foot balance. Grip strength of exercise group is decreased as older, but of farmer group is usually fixed without regard to age. 6. In the corelation between the physical fitness and shape, stature and weight are closely related to side step, vertical jump, and standing trunk flextion. Chest of exercise group is also deeply related to step test. 111 the corelation between the physical fitness and function, the physical fitness has deep connection with respiratory rate but it shows low corelation to pulse rate. The corelation between Rohrer’s index and the physical fitness shows sttentive relation in side step and vertical jump of both groups.

The purpose of this study was to measure the number of Jumps for spike in each position and to find out in what position the most physical fitness was consumed. The subjects were 18 male players who were divided three groups of six One was the left, another was the right. the other was the center. The apparatus was Lactate Analyzer(YSI U.S.A). The results of study were as follows : 1. In male volleyball game, the number of jumps for spike in each position was like that; The left was 32, the center was 46. the right was 26. So, the center most frequently attempted for spike during 5set. 2. In the group of the left, after spiking the blood lactate concentration was changed from 2.32±0.23mM to 4.5±0.90mM and in the center it was changed from 2.23±0. 23mM to 8.58±2.10mM and in the right it was changed from 2.35mM to 5.51±1.66mM So, in the group of the center the most the blood lactate concentration was increased. 3. Before spiking there was of not difference between the in-group and the inter-group, but after spiking there was a little difference-(P <.01)-for the inter-group. 4. After spiking there was a little difference-(P <.01)-between the center and the leftand there was also a little difference-(P <.05)-between the center and the right.

This paper aims to examine, centering on documents, whether energy metabolism is the dominated factor which has influence on physical strength and record improvement of individuals who enjoy leisure and sports, or professional athletes, or not. The study on energy intake in the aspect of nutrition and sitology has been made a lot, and most people have been concerned with energy intake more than energy consumption, but the study of the mechanism and intake amount of energy in aspect of motion physiology remains to be done. To meet this problem, with the purpose of cultivating superior athlete through the good understanding mechanism of energy consuming metabolism and the scientific nutrition control and physical strength training, this study proposes the following: 1) Having a meal just before athletic has nothing to do with the improvement of motion performing capacity; eating habit in daytime while training has much influence on the accumulation and recovery of energy: the final meal before sports should be taken at least 3 hours before ; balanced eating habit has effect on the maximization of function of performing motion 2) The dissolution of protein while training plays a role as energy source of supplying ATP for diminishing muscle and in case of eating high protein food, quite a little of all the protein is used as an energy source; the rest of it is not accumulated. 3) one of chief factor of causing muscle during intense exercise, which makes it impossible to produce ATP, and cause muscle fatigue.

This study aims to examine, centering on documents, the mechanisms by which exercisers gain and lose heat, the physiological consequences of exercising in the heat, acclimatization strategies, and exercise prescriptions for general people. The studies on exercise in hot have been made a lot and these studies are based upon exercise testing within favorable environmental conditions. But exercise training often occur within environments that are much warmer and more humid than the test conditions. The consequence of exercising in hot and humid conditions includes an exaggeration of the heart rate response compared to responses within more favorable conditions. Moreover, exposure of unacclimatized individuals to adversely hot conditions predisposes them to heat-related illness. To minimize the impact of exercise within hot conditions, exercise professionals should instruct the exercisers by utilizing the following guidelines during exercise in the heat. 1. Start slow. Allow sufficient time for heat acclimatization to take place. 2. Exercise in the early morning to minimize the impact of solar radiation on the heat load. 3. Exercisers must drink water frequently during exercise. 4. Don't endure thirst. 5. Do not take salt or potassium tablets.
