Physiological Effects of YOGA
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.9 Vol.9】
These days, YOGA is regarded as one of the breathing for health in Japan, which was oriented in India in B.C. centuries.
The aim of YOGA practice is to let the person accomplish his selfcontrol. In order to meet the aim he has to train abdominal breathing and to strengthen his physical functions.
The purpose of this study is to find physiological effects of YOGA-breathing which is widely accepted as a method good for health.
The findings were follows:
1) According to the questionnaires on the effects of YOGA activities, given to 75 persons, the participants of about 80 percents felt light in weight, easy to move, warmer in body and more related. This was a proof of its useful activities for health.
2) An oxygen uptake of female trained for one year and a half during YOGA was more than females trained for five years and above (p<0.01 and P<0.05). But a change in the oxygen uptake of untrained female was large and drew a drastic curve. On the other hand, that of the trained females were small and showed a rhythmical changes. The importance of the balance in breathing and YOGA activities was clearly observed in the result here.
3) The coefficient of variation of R-R intervals (CVR-R) in ECGs is an indication of the autonomic nervous system function and is considered to be a parameter of the parasynipathetic nervous system function. The trained females showed an affection of the parasympathetic nervous function and the untrained female the sympathetic nervous function. This means that the trained can manage self-control and the untrained can't.
4) A blood pressure after YOGA tended to fall both in systolic and diastolic pressure.
From the results, YOGA activities in daily life refresh our body and mind and seem to contribute to release us from stress.
The physiological data indicated that the measurable amount of periods should be required for the YOGA trainer to be fully absorbed in meditation, which was the highest level of it activities.
