概要	The hypothesis of the present study was that low-repetition high-impact jump training would be effective for enhancing bone cross-sectional geometry rather than increasing DXA measured BMC and aBMD in post-menopausal women.Thirty-three middle-aged post-menopausal women (mean age, 61.2 ± 5.6 years; range, 53-74 years) were divided into two groups: jump training group and control group. The Jump group jumped 20 times per day, twice a week for 12 months on a shock absorbing pad.In middle-aged postmenopausal women, aBMD measures were not related to jump training effects which supports the notion that long bones tend to change their size and geometry rather than amount of mineral in order to meet the increased functional demands associated with low-repetition high-impact loading.
