This study was examined the effects of deepsea water (DSW) supplementation and swimming exercise on bone metabolism in growing male rats. Thirty-two Sprague-Dawley male rats, 6 weeks of age, were randomly divided into high-fat diet sedentary (HS, n=8) or exercised group (HE, n=8) and DSW supplemented sedentary (DS, n=8) or exercised group (DE, n=8), given a high fat diet to all groups for 8 weeks. In the results, serum osteocalcin level of the DS was significantly lower than that of the HS (p less than 0.01). In addition, femoral bone mineral density (BMD), tibial bone mineral content (BMC), and breaking force of the DS were significantly higher than that of the HS (p less than 0.05). Furthermore, femoral BMD and tibial weight of DE were significantly higher than that of the HE (p less than 0.05). These results suggest that drinking deep-sea water and exercise has a crucial role for prevent osteoporosis and increase peak bone mass in growing male rats.
