[Effects of exercise on immune functions in mice].
This study was carried out to examine the effects of forced running exercise on the immune functions of male ICR mice. Mice aged 4 weeks were divided into two groups: a non-exercise group (control) and a group given forced running exercise (exercise group). The exercise applied was forced running at 15m/min on a flat floor without any slope for 60 min a day. The duration of exercise was 5 days per week for 12 weeks. The results obtained were as follows: 1) After 12 weeks of forced running exercise, the weight of the anterior tibialis muscle and succinate dehydrogenase activity in the anterior tibialis muscle increased significantly (p < 0.01) in the exercise group compared with the control group. A tendency for thymus weight to increase was shown in the exercise group, and liver and spleen weights were significantly (p < 0.01) greater than in the control group. 2) The potentiation of phagocytic function of the reticulo-endothelial system, examined by the carbon clearance method, was seen in the exercise group. 3) The ability of peritoneal macrophages (M phi) to phagocytose latex beads significantly increased (p < 0.01) in the exercise group. The acid phosphatase activity of peritoneal M phi remained in both groups. However, lactate dehydrogenase activity of peritoneal M phi significantly increased (p < 0.01) in the exercise group compared with the control group. 4) The proliferation of splenocytes induced by Con A in the exercise group significantly increased (p < 0.01) compared with the control group.(ABSTRACT TRUNCATED AT 250 WORDS)
