摘要
对105例中老年女性右跟骨定量超声参数和身份成分测量,结果BUA:快步走组最高,冬泳组最低;太极拳组与不运动组比较有差异(P<0.05);快步走组与不运动组、冬泳组比较有显著性差异(P<0.01);其他组间比较无差异性。不同运动项目BUA与体脂率的相关分析,回归方程为:BUA=-1.674FAT+113.86;太极拳运动的体脂率与BUA相关性分析,回归方程为BUA=-0.816FAT+86.85。结论对骨骼有一定冲击力的运动形式如快步走、太极拳对骨密度改善效果较好,冬泳改善骨密度效果较差;在体重无差异性的情况下,BUA与体脂率呈负相关,提示应力因素对骨密度的影响更为重要。
Ostespace ultrasonic bone dersity and the body component of 105 women are measured and the follouing results are revealed ： In terms of BUA, the fast walking group is the highest, while the winter swimming group is the lowest. There is difference between the Taiji group and the non - sport group （ P 〈 0.05 ） ; there is marked difference between the fast walking group and the non - sport group（ P 〈 0.01 ） ; there is marked difference between the fast walking group and the winter swimming group（ P 〈0.01 ） ; there is no difference between other groups. The regression equation for the analysis of the correlation between BUA of different fitness activities and body fat percentage is BUA = - 1. 674FAT ＋ 113.86 and the regression equation for the analysis of the correlation between the fat percentage of Taiji exercises and BUA is BUA = -0.816FAT ＋86.85. IIt is concluded that fitness exercises like Taiji have a positive effect on the bone density of middle - aged or old women, which is affected by the exercise means. Such exercises as fast walking and Taiji have a positive and good effect on the bone, while winter swimming, has a poor effect on improving bone density. If there is no difference in body weight, BUA and the fat percentage are negatively correlated, implying that stress factors have a more important effect on the bone density.
