本研究的目的在探討24 週軀幹肌和姿勢肌之運動訓練對停經後骨質不足婦女的效果。二十八名經血以確切合乎受試者標率的婦女參與且完成本研究，14 名息者志願接受每週二次每次約30 -40 分鐘的運動訓練，訓練項目主要為軀幹肌和姿勢肌的訓練，另14 名息者則不接受此等運動訓練是為對照組。所有的受試者在研究期間均不得改變其藥物、飲食或生活型態，並在24 週的前、復接受軀幹肌和膝伸肌之肌力與耐力、一分鐘仰臥起坐和伏地挺身、身龍組成、最大攝氧量以及三處骨密度( L2-4股骨頭和遠端股骨）的測量結果顯示兩組間在L2 -4 骨密度（6 . 3 vs 1 . 9 % ）、膝伸肌肌力、軀屈肌耐力有明顯的差異（P < 0 . 05 ) 。
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.
