To better understand the effects of exercise mode on bone health, the bone mineral density (BMD) of 171 male undergraduates from Physical Education Department and Chemical Education Department of South-China Teachers University, were measured with single photon absorptionetry (SPA) and their physical fitness was monitored. The results were as follows: 1. The values of BMD in short-distance running, football, basketball, wushu, long-distance running and sports population groups were higher than those in control group. 2. Exercise intensity and exercise history were positively correlated with the values of BMD, and exercising more than 3 times per week could improve BMD significantly. 3. Muscle strength and muscle strength/body height indexes were correlated with the value of BMD (r=0.661, r=0.623). In order to increase peak bone mineral density to prevent osteoporosis, the exercise programme should be high in intensity, half an hour each time and more than three times per week.
