Abstract

The purpose of this study is to propose an effective exercise intervention program to prevent and control osteopenia and osteoporosis that result from aging. To the end of this study, a circuit training intervention was performed for 8 weeks among participants with osteopenia who resided in Gyeonggi Province and were aged 65 and whose T-score of dual energy X-ray absorptiometry was between -1.0 and -2.5. Based on the effect of this intervention on their bone metabolism markers and bone density, the following conclusions were derived: First, it turned out that the circuit training intervention had statistically significant interactive effects on bone metabolism markers (osteocalcin and deoxypyrid-inoline) of old women with osteopenia depending on the measuring timing and groups. Second, it turned out that the circuit training intervention had statistically significant interactive effects on the bone density (T-score) depending on the measuring timing and groups. The conclusions above indicate that the circuit training intervention showed positive effects on bone metabolism markers and bone density of old women with osteopenia, being viewed as an effective intervention program applicable in order to prevent and control osteopenia and osteoporosis in line with bone density decrease.
