In order to investigate the influence of the habitual physical training on the function of digestion and absorption test (3-DATs, oral glucose tolerance test: OGTT, oral starch tolerance test: OSTT, oral butter tolerance test: OBTT) and maximal exercise test at pre- and post-training. Serum glucose, triglyceride (TG) and cholesterol (CHO) concentrations and α-amylase and lipase activities were measured before and after each test and compared pre- and post-training. The results were summarized as follows;
　The mean accelerations of the clearing rate of glucose in serum, and of releasing rate of glucose to serum were observed in OGTT and OSTT. And the mean inhibitions of the releasing rate of TG and CHO in serum were observed in OBTT.
　Then the influences of running training were observed in the changes in serum α-amylase and lipase activities on 3-DATs and maximal exercise test, but the mechanism of the changes of α-amylase and lipase were still unknown.
　It seems likely to suggest that the habitual physical training affects on the digestional and the absorptional functions.
