Abstract This longitudinal study examined whether bone mineral density (BMD) of the lumbar spine and the proximal femur is maintained in pre-, peri-, and postmenopausal women by regular exerise. BMD was measured using dualenergy X-ray absorptiometry (DXA). Twenty-six Japanese women (mean age 47.8 years) were followed 4–5 years. Twenty-two subjects from volleyball or jogging clubs had participated in the same exercise for more than 5 years at the initial BMD measurement. Longitudinally, for these 22 athletes, the rate of change per year in BMD of the lumbar spine was -0.17% in the premenopause group and -2.60% in the perimenopause group. In the proximal femur of the athletes, BMD increased (rate of increase per year 1.80%) in the premenopause group, but decreased (rate of decrease per year 1.07%) in the perimenopause group. In the premenopause group, BMD of the proximal femur increased in all athletes. However, in the proximal femur, the nonexercise group showed a 0.31% decrease, a significant difference (P 〈0.05) compared with the athletes. These findings suggest that women can achieve continuous gains in bone mass in the proximal femur before menopause by regular intense exercise. However, continued high-level physical activity in the perimenopausal women was not able to prevent bone loss.
