Phagocytic cells, polymorphonuclear peucocytes and macrophage, play an important role in a non-specific cellular immunity which is first defence line for infectious disease. The purpose of this paper is to clairfy combined effects of stressful exercise and sleep disturbance on rat non-specific cellular immunity represented by yields of cells from bronchoalveolar lavage and superoxide generating capacity of alveolar mecrophage. Male Wistar rats(5 weeks old) were divided into following 4 groups. 1) Training group: exercised on a treadmill at a belt speed of 35m/min for 45min/day. 2) Jet Lag group; noninvasive sleep disturbance by the shifted day/night time every 2 week interval. 3) Training+Jet Lag(T+L) group; exercised on a treadmill with sleep disturbance, that we assumed one of chronic fatigue model in this paper, and 4) Control group; set sedentary condition. After 6 weeks of the experiment, 2 groups were newly selected from T+J group for the examination of rest effects on the chronic fatigue model rats. And to examine the combined effects of stressful exercise and sleep disturbance on matured rats(11 weeks old), Acute Training + Jet Lag(AT+J) group was selected from the Control group. Rats were sacrificed at 11 and 17 weeks old. T+J group seemed to be able to adapt first 6 weeks but negative effects were found out at 17 weeks old. Same phenomena were also recognized in AT+J group. These results suggest that the chronic fatigue model rats may easily catch the infectious disease and there are possibility that both stress, stressful exercise and sleep disturbance, negatively affects the non-specific cellular immunity, especially after maturation.

In this study 8 male athletes and 8 female athletes for matches requiring endurance were examined for the purpose of comparison and analysis on the effect of absorption of sugars and effect of absorption of sugars+protein+fats restoration of muscular glycogen after elapse of 4 hours subsequent to closing 90 minutes exercise. (Amount of energy absorbed was same). Examinees were tested with 3 kinds of performance such as CPF Performance whereby they were made to take ① sugars (0.75 g/㎏) and protein (0.1g/㎏) and fats (0.02 g/㎏) after elapse of 1 hour subsequent to long hours of exercise and CHO Performance whereby examines were made to take ② sugars (1g/㎏) alone and Performance whereby they were made to take ③ placebo (which does not contain any sugars, protein or fats). Also the examinees took meals which had same amount of energy and nitrogen during the Performance on the date prior to experiment or on the date of experiment. Women during the exercise showed significantly higher rate of oxidation of fats, basic element of energy than that of men. In CHO Performance and CPF Performance value of blood sugar and density of insulin were significantly higher in comparison with performance with placebo. At such cases there was no difference between different genders. Same kind of phenomena were confirmed with restoration of muscular glycogen. From such fact it could be observed that absorption of fats alone and absorption of sugars+protein+fats in comparison with absorption of placebo after exercise promoted relatively higher level of restoration of muscular glycogen for both men and women.

The purpose of this study was to examine the effects of exercise program participation on subjective well-being and exercise adherence in 35 middle-aged subjects. A model for promoting exercise adherence was developed as a cycle model of 4 comstructs(self-awareness, intrinsic motivation, voluntary acts, masteryㆍsatisfaction). After 6-month exercise program participation, there was no significant effect of exercise on morale level as a whole, but in the subjects with low initial morale level, there was a significant correlation between the initial level and the increase in morale. In the model, the causality between the constructs was confirmed as hypothesized at beginning and end of the program. Enhancement in the constructs and causality was showed after the program. The reinforcement of the model was showed in the subjects who did voluntary exercise program participation might enhance subjective well-being in the subjects with low moral level, and could improve exercise adherence especially in the subjects with high moral level.
