OBJECTIVE: This study was designed to clarify the effect of swimming exercise during 12 weeks on total body bone mineral density(T-BMD) in rats. METHODS: After a week of stabilization, sixteen male Wister-Kyoto (WKY) rats at the age of 4 weeks were randomly divided into two groups: non-swimming control group(Cont group; n=8) and swimming exercise group(Swim group; n=8). After more two weeks of adaptational period to swimming exercise, the Swim group exercised in the pool with 60min/day, 5day/week for 12 weeks. All rats were allowed free access to food and tap water in all groups. T-BMD and BMC were measured three times at initial, middle and end of the experimental period. After experimental period, rats were sacrificed and femur bones were removed for measure of BMD and bone intensity. RESULTS: The mean intake volume(g/day/rat) during over experimental period of Swim group were approximately 6.6% higher than that of Cont group(p<0.01) while there are not significant difference in the body weight between two groups. Although T-BMC of Swim group was approximately 15%(p<0.001) and 16%(p<0.001) higher than those of Cant group, respectively, at both of after 6 weeks and end of exercise period, T-BMD of Swim group was approximately 1.8%(p<0.05) higher than that of Cant group at only end of exercise period. Femur mass, BMD, BMC and elasticity of Swim group were approximately 4.6%(p<0.001), 5.2%(p<0.01), 12.3%(p<0.001) and 20.2%(p<0.05) higher than those of Cant group, respectively. CONCLUSION: These results suggest that swimming exercise might improve BMD in both total body and a part of bone and there are a difference between quantity and quality in bone growth.
