Abstract

中高年女性13名(平均年齢67.5±3.3歳)に対し,約2.5ヵ月間の体幹・下肢健康(貯筋)運動〔椅子座り立ち,もも上げ,せのび,下肢外転,上体起こしの5種類〕を指導し,以下の2つの知見を得た.(1)運動期間後では運動前に比し,全身身体組成(DEXA)上,全身と下肢の除脂肪骨体重・下肢骨密度の増加,全脂肪量・体脂肪率の減少が,それぞれ統計学的に有意に観察された.(2)運動群の運動後の左大腿骨頸部においては,Ward領域骨密度の有意な増加が認められた.なお,荷重運動非指導の対照群女性8名(平均年齢65.3±5.7歳)では,上述のような有意な変化は一切認められなかった.以上より,中高年女性に対する体幹・下肢健康(貯筋)運動は,有益であると考えられた.

We investigated the effects of physical exercise of NIFS Chokin Project (average 2.5 months) on body constituents and bone mineral density (BMD) of 13 middle and old-aged women (average 67.5 ± 3.3 years old). Several findings were obtained as follows. (1) For whole body DEXA results after exercise, total lean mass, legs BMD, legs lean mass significantly increased (p < 0.05) and total fat mass, total fat % significantly decreased (p < 0.01) when respectively compared with those before exercise. (2) For left femur DEXA results after exercise, BMD in the Ward's triangle area significantly increased (p < 0.01) when compared with that before exercise.<BR>Middle and old-aged women in the control group (non-loading exercise, average 65.3 ± 5.7 years old) did not show such significant changes. These results suggest that healthy exercise of NIFS Chokin Project had good effects on the bone of middle and old-aged women.
