Title Long-term exercise using weighted vests prevents hip bone loss in postmenopausal women
Date 2000
Description Background. Bone mineral density (BMD) is a primary risk factor for hip fracture. We studied the effect of long-term weighted vest plus jumping exercise on hip BMD in postmenopausal women as a strategy for reducing hip fracture risk. Methods. Eighteen postmenopausal women (age 5 64.1 6 1.6 years at baseline, 69.9 6 1.6 years at post-testing) who had participated in a 9-month exercise intervention volunteered for the long-term trial. Nine of the original group engaged in weighted vest plus jumping exercise three times per week for 32 weeks of the year over a period of 5 years. Nine of the original controls were active but not enrolled in the exercise program. BMD of the proximal femur was assessed by dual energy x-ray absorptiometry at baseline and after 5 years. Results. At baseline, groups were similar for age, weight, height, years past menopause, and BMD of the femoral neck, trochanter, and total hip. At follow-up, differences in BMD at all regions of the hip were higher in exercisers than controls. For exercisers, changes in BMD were 11.54% 6 2.37%, 20.24% 6 1.02%, and 20.82% 6 1.04% (means 1 SE) at the femoral neck, trochanter, and total hip, respectively; controls decreased at all sites (24.43% 6 0.93%, 23.43% 6 1.09%, and 23.80% 6 1.03%, respectively). Conclusions. A 5-year program of weighted vest plus jumping exercise maintains hip BMD by preventing significant bone loss in older postmenopausal women. Furthermore, this particular program appears to promote long-term adherence and compliance, as evidenced by the commitment of the exercisers for more than 5 years.
