Articles : Effects of Swimming Exercise Bone Mineral Density in Osteoporosis-induced Rats
In the present study, 5mg/kg BW glucocorticoid was used for developing osteoporosis to the twenty SD male rats. After this treatment, swimming as an exercise therapy to cure osteoporosis was performed for 6 weeks. They ingested commercial diet for the periods of experiment ad-libitum. Abdominal fat accumulation, bone mineral density (BMD), bone mineral content (BMC), and bone broken strength were measured with DEXA and Instron. Bone length and diameter were measured with caliper. Swimming exercise training reduces body weight gain during exercise periods and decreases fat accumulation in epidydimal and mesentary (p<.05). Bone length, diameter, and BMD were not different between groups. However. BMC was increased in swimming exercise group (p<.05). These results suggested that swimming exercise training has the less effect of increasing bone related items as compared as weight bearing exercise training in rats. Therefore, if the more investigate might performed, swimming exercise and other exercise regimen or some supplement has the better effect on the glucocorticoid-induced osteoporosis.
