太极拳锻炼结合补钙对绝经后女性骨密度的影响

Effects of taijiquan exercises combined with orally calcium supplement on postmenopausal women′s bone mineral density

目的:探讨太极拳锻炼结合口服钙对绝经后女性骨密度的影响。方法:绝经女性80例,随机分为4组,A组:太极拳锻炼加补充钙剂。B组:单独进行太极拳锻炼。C组:单纯进行补钙。D组:对照组,不进行任何干预。采用双能骨密度仪对受试者L2-4进行骨密度测定。各组间骨密度变化采用单因素方差分析,各组内干预前后、停止干预20周后的对比采用配对t检验。结果:A组骨密度增加明显,与D组比较具有显著性差异(P<0.05);停止干预20周后,C组明显降低(P<0.05)。组间综合疗效比较,A组优于B组(P<0.01),B组优于C组(P<0.001)。结论:太极拳锻炼和钙剂补充均能帮助绝经妇女防止骨量丢失,增加骨密度,太极拳锻炼加补钙的作用优于单纯太极拳锻炼,同时太极拳锻炼在停训后一段时间内有维持骨量的效应。

Objective：Exploring the effects of taijiquan exercises combined with oral calcium on bone mineral density （BMD） in postmenopausal women. Method： Eighty cases of post-menopausal women were randomly divided into 4 groups, A group： taijiquan exercises combined with calcium supplement. B group： taijiquan exercises alone. C group： calcium alone. D group： control group, without any interference. A dual-energy BMD instrument was used to determine BMD in the subjects＇ L2-4. Single factor variance was used to analysis the changes of BMD in each group, before and after intervention and 20 weeks after cessation of intervention. Result： BMD of A group increased significantly, compared with D group （P〈0.05）; 20 weeks after cessation of intervention, BMD of C group decreased significantly （P〈0.05）. Integrated effect in A group was better than that in B group （P〈0.01）, that in B group was better than that in C group （P〈0.001）. Conclusion： Taijiquan exercises and calcium supplement both are helpful for postmenopausal women in preventing bone loss and increasing BMD. The role of taijiquan exercises combined with calcium supplement is better than simple taijiquan exercises. Taijiquan exercises is effective in maintaining BMD for a period of time after training cessation.
