This study conducted regular aerobic exercise for men in their 20s and 30s who are socially living in a modern society where various lifestyle-related diseases are prevalent in recent years. This study is to investigate the e ffects of AS T and ALT, which a re f actors o f liver function, and vascular aging that affects long-term physical health. The purpose of the study was to present it as basic data for the development of a health exercise program to recover and maintain the health of men with reduced liver function. The liver function factor AST showed significant differences in the second order and the third order excluding the first order between the two groups. ALT showed significant differences in the 2nd and 3rd excluding the 1st between the two groups. Vascular aging showed significant differences in the 2nd and 3rd excluding the 1st between the two groups. Vascular aging showed significant differences in the 2nd and 3rd excluding the 1st between the two groups As for the improvement effect of liver function factors, there was a significant difference in effect between the two groups' timing, timing*group, and group. As for the improvement effect of vascular aging, there was a significant difference in effect between the timing, timing*group, and group of the two groups. Therefore, regular aerobic exercise showed a positive effect in rebuilding liver function of men with reduced liver function in their 20s and 30s, and blood vessel aging was also improved, indicating that the aerobic exercise program had an effect.
