The purpose of this study was to investigate changes of pulmonary diffusional capacity with three different exercise modes. experiment one was strenous step exercise during the 3 min. which affected DLco so diffusional capacity was signifcanty increased 31.98 ㎖/min/mmHg to 44.42 ㎖/min/mmHg. Experiment two was on the treadmill running at 80% THR for 60 min. and after 30 min. which affect men DLco to deorease 14.5%(27.17 ㎖/min/mmHg) and women DLco to de-crease 8.3%(30.1 m/min/mmHg). So mean values was decrease 11.4% by experiment two. Experiment three was resting DLco comparison between athletes and control which revealed that athletes increased DLco about 50% than control(general students). DLco induced the exercise was reduced by inorease pulmonary blood folw and a-v diff. in active muscle. DLco decrease in the recovery 30 min. was explained that respiratory muscle fatigue and active muscle losed pumps, decreased venous return, DLco / Va, and K’s C. In the resting levels, Athletes whose DLco increased significantly was by increase stioke volume and pulmonary capillary blood volume in athletes.

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.

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.

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 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.
