48周不同频率太极拳练习对老年女性骨密度的影响

目的探讨相同周期、不同频率的太极拳练习对老年女性骨密度(BMD)的影响。方法年龄、身高和体重相匹配的低频组(n=36,1次/周)、中频组(n=37,3次/周)、高频组(n=38,6次/周)和对照组(n=37),在48周前后采用XR~46双能X线测试腰椎L_(2-4)和右侧股骨近端(股骨颈、Ward’s三角区和大转子)BMD。结果 1)0周与48周组内比较:中频组和高频组腰椎L_(2-4)、股骨颈和大转子BMD不同程度显著增大(P〈0.05)。其中高频组大转子BMD非常显著增大(P〈0.01);2)48周后组间比较:中频组和高频组腰椎L_(2-4)、股骨颈和大转子BMD显著大于对照组(P〈0.0...

Summary:目的探讨相同周期、不同频率的太极拳练习对老年女性骨密度(BMD)的影响。方法年龄、身高和体重相匹配的低频组(n=36,1次/周)、中频组(n=37,3次/周)、高频组(n=38,6次/周)和对照组(n=37),在48周前后采用XR~46双能X线测试腰椎L_(2-4)和右侧股骨近端(股骨颈、Ward’s三角区和大转子)BMD。结果 1)0周与48周组内比较:中频组和高频组腰椎L_(2-4)、股骨颈和大转子BMD不同程度显著增大(P〈0.05)。其中高频组大转子BMD非常显著增大(P〈0.01);2)48周后组间比较:中频组和高频组腰椎L_(2-4)、股骨颈和大转子BMD显著大于对照组(P〈0.05)。高频组腰椎L_(2-4)、股骨颈和大转子BMD显著大于低频组(P〈0.05)。中频组股骨颈BMD显著大于低频组(P〈0.05)。结论每周3次或6次的太极拳练习对提高老年女性腰椎L_(2-4)、股骨颈和大转子BMD有积极作用,随着练习频率的增加效果越显著。
Bibliography:Objective To research on the effects of Taichi exercise given in the same duration but different frequency on bone mineral density( BMD) in older women. Methods Dividing the subjects in to three different groups based on age,height,and weight,including low frequency group( n = 36,once/week),intermediate frequency group( n = 37,3 times/week) and high frequency group( n = 38,6 times/week). After 48 weeks,using XR-46 model dual energy X-ray absorptiometry,the BMD of lumbar spine L_(2-4) and right proximal femur( femoral neck,Ward's triangle and greater trochanter) was assessed. Results 1)Baseline and 48 weeks group comparison: in the intermediate frequency and high frequency groups,BMD of femoral neck,lumbar spine L_(2-4) andgreater trochanter increased significantly at different levels( P〈0. 05). The high frequency group had the greatest increase in greater trochanter BMD( P〈0. 01); 2) Between group comparison at 48 weeks: the intermediate frequency and high frequency groups had significantly greater femoral ne
