Abstract
Osteoporosis is one of the most common skeletal disorders affecting postmenopausal women. The purpose of this study was to investigate whether an exercise program designed mainly to the trunk and postural muscles was beneficial for bone mineral density (BMD) in osteopenic postmenopausal women. Osteopenia was defined to be more than one standard deviation below the mean BM]3 of premenopausal women in this study.Twenty-eight postmenopausal women participated in this study, 14 in exercise group and 14 served as controls. The BMD of the spine (L2 to L4), right femoral neclq and distal femoral condyles of each woman was examined by dual X-ray absorptiornetry. In addition, measurements of number of sit-ups and push-ups in one minute, strength and endurance of knee extensors and trunk muscles, body composition, and maximal oxygen consumption were taken. The exercise program was instructed to all subjects that took 20- 30 minutes long per session three times per week for 24 weeks, once a week being supervised by physical therapist in hospital. The results showed that in the exercise group had significant improvements in BMD of L2-4, number of sit-ups and push-ups in one minute, strength and knee extensors, and maximal oxygen consumption after 24 weeks, while decreases in strength of knee extensors and endurance of trunk flexors. The between-group comparisons showed significant improvements in
BMD of L2-4, strength of knee extensors, trunk flexor endurance, and number of sit-ups over those of the control group. In conclusion, minimally supervised trunk and postural muscle exercises was able to improve BMI) of L2-4, and strength of knee extensors and trunk flexors.
