Everyone is eager to prevent sports injury and to relieve his fatigue by means of the maintenance and improvement of his health, the mental and physical safety, and the regular health life, In this consideration of the study I tried to find the physical change in the stability by way af pre-test and in the physical load given. Conclusion 1. Fasting sugar showed a slight decrease. All the examinees showed a slighter decrease after exercises than stability, 2. The change of uric acid showed 3.1㎎/㎗ on an everage, But after exercises it increased 4.3㎎/㎗. 3. I found little difference in the change of creatinine before and after exercises. 4. In stability total protein skewed a high value of 7.4㎎/㎗. and after exercises it showed a slight decreased value of 7.2㎎/㎗ 5. albumin showed a slight decreased value also after exercises. 6. The change of total cholesterol showed 154㎎/㎗ in stability, and after exercises it showed 144㎎/㎗, which was the greatest change, f think. 7. Urinc color was the normal state color straw and Ember, and specific gravity increased more after exercises than in stability. The change of bilirubin showed negative in all the examinees after exercises. 8. The change of urine protein showed trace in two examinees after exercises. It showed less difference in increase or decrease on the girl students of physical education than on thous of the general courses of college. I regard this as the girl students of physical education can get to have effective adaptation to their physical load, which adaptation maybe created by frequent physical change caused by everyday regular exercises.
