The purpose of this study was to investigate the effect of aerobic exercise on cardiopulmonary function, body composition, and bone mineral density in male college students over a period of 8 weeks. Twenty-four male students were randomly assigned to the following groups: low intensity walking group (50~60% VO2 max, n=6); moderate intensity jogging or fast-walking group (60~70% VO2 max, n=6); high intensity running group (70~80% VO2 max, n=6); and control group (no exercise, n=6). The exercise program was conducted for 50 minutes every 3 weeks for a total of 8 weeks. After 8 weeks, the factors affecting the measurement variables were analyzed and the following results were obtained. Eight weeks of exercise significantly increased maximal oxygen uptake, regardless of exercise intensity, but no changes were observed in the control group. Body mass index decreased in all exercise groups, but there was no significant difference in the control group. Body fat (%) and abdominal fat (%) significantly decreased in all exercise groups, but significantly increased in the control group. Bone mineral density showed no differences between the groups. In conclusion, an 8-week exercise program for college students showed positive effects on cardiorespiratory function and body composition, regardless of exercise intensity. Future studies should be conducted considering the various options of exercise intensity, duration, frequency, and type of exercise to improve health care and physical fitness of college students.
