• It is recently observed that there is in a tendency toward obesity or deficiency of endurance to the physique among schoolchildren. Consequently there is much interest for exercise through our nation. Noting these facts, we conducted experiments similar to those previously reported for getting basic data of body composition, by loading 28-days exercise on male rats on 8 percent and 20 percent casein diets. 1. The food intake of the exercise groups was smaller than that of the control in each pair. During the exercise period, food intake of group 11 also showed similar decreases to those in group I, however, during the rest period, food intakes increased as compared to those of the control. In comparison of caloric requirement for lg increase of body weight, exercised rats showed higher calories than the control in exercise periods. In the rest period, however, these caloric values decreased as compared with the control. 2. For organ weight per 100g of body weight, significant difference was observed in the heart and kidneys. The gastrocnemius muscles showed almost similar values to the control. The liver and testes did not differ in the weights per 100g of fat free mass of body between the exercise and the control] groups. 3. The water contents (%) in the carcasses of exercised rats each fed the 8% and 20% casein diets in group I and I' differed significantly when compared with the control animals, but there was no difference in the water contents of the organs of all groups. 4. In the case of exercised rats in groups I and I', body lipid contents (%) were significantly lower than that of the control group, irrespective of the protein levels in the diets. On the other hand, for rats fed the 8% casein diet in group II, there was no difference in lipid content (%) in the carcasses as compared with the control rats. In the 8% and 20% casein diet groups, lipid contents (%) in the liver of exercised rats in groups I and I' also decreased considerably compared with the control level. In group II, the lipid content in the liver recovered to the control level or had a tendency to increase slightly. 5. The differences of body weight between the control and the exercised rats in each group were nearly equal to the difference of the sum of body lipids and water contents in the whole body between the two groups. From these data, it was suggested that the differences of body weight in each group between the exercised and control rats could be explained as the changes of lipids and water contents in the body.
