摘　　要：目的探究抗阻训练对60岁以上老年人全身和下肢骨折高发部位(腰椎、髋关节、股骨大转子和股骨颈等)骨密度(BMD)的影响。方法计算机检索中国知网(CNKI)、PubMed、Elsevier、Web of Science(WOS)等数据库,全面收集有关抗阻训练对老年人BMD影响的随机对照试验研究(RCT);运用Cochrane偏倚风险评估工具对纳入文献进行方法学质量和发表偏倚性评价;采用ReMan5.3.5软件对所得数据进行统计学处理和敏感性检验。结果共纳入文献17篇,其中低偏倚风险6篇,中等偏倚风险9篇,偏倚风险较高2篇;纳入分析总样本量719人,平均年龄均大于60岁。meta分析结果显示,抗阻训练对老年人全身(SMD=0.21,I2=68%,P=0.38)和股骨大转子BMD(SMD=0.22,I2=56%,P=0.22)具有一定提高作用,但无显著性。抗阻训练可显著提高老年人腰椎(SMD=0.46,I2=70%,P=0.01)、髋关节(SMD=0.34,I2=16%,P=0.005)和股骨颈BMD(SMD=0.53,I2=60%,P=0.000 5)。结论抗阻训练对老年人BMD有一定提高作用;对老年人腰椎、髋关节和股骨颈BMD具有显著的提高作用。适当的抗阻训练可有效保护老年人骨骼,预防骨质疏松。Objective:To explore the effect of resistance training on bone mineral density(BMD)of total body and parts with high incidence of fracture of lower body(lumbar spine,total hip,trochanter and femoral neck)in elderly people over the age of 60.Methods:CNKI,PubMed,Elsevier and WOS databases were searched,and all randomized controlled trials of resistance training on BMD in older adults were collected.Cochrane bias risk assessment tool was used to evaluate the quality and publication bias of the included articles;ReMan5.3.5 software was used for statistical analysis and data sensitivity test.Results:A total of 17 articles were included into meta-analysis,6 with low risk of methodological bias,9 with moderate risk of methodological bias and 2 with high risk of methodological bias.The total sample size was 719,and the average age was more than 60 years old.Meta analysis results show that resistance training can improve the total body(SMD=0.21,I2=68%,P=0.38)and trochanter(SMD=0.22,I2=56%)BMD in the elderly,but there is no significance.Resistance training can significantly improve the lumbar spine(SMD=0.46,I2=70%,P=0.01),total hip(SMD=0.34,I2=16%,P=0.005)and femoral neck BMD(SMD=0.53,I2=60%,P=0.000 5)in the elderly.Conclusion:resistance training can improve the BMD of the elderly,and can significantly improve the lumbar spine BMD,total hip BMD and femoral neck BMD in the elderly.Appropriate resistance training can effectively protect the bones from osteoporosis.
