水中运动对中老年人骨密度影响Meta分析

Effect of The Aquatic Program on Bone Mineral Density in Middle-aged and Elderly People:A Meta Analysis

对纳入文献整理并进行有效合并,扩大样本容量,定量评价水中运动对中老年人骨密度影响,为影响中老年人骨密度,降低跌倒风险,提供科学、有效、安全的健身方式。以水中运动、中老年人、骨密度、游泳、aquatic therapy、aquatic plyometric training等为主题词;aquatic organisms、bone mineral density、density、the elderly等为关键词在Pubmed、知网等数据库检索,检索文献共1217篇,经过筛选后,最终纳入文献12篇。水中运动与对照组相比,对中老年人腰椎、桡骨、跟骨骨密度影响具有显著性差异,股骨骨密度则具有非常显著性差异,陆上抗阻运动对腰椎骨密度影响显著,但对股骨骨密度无显著性差异。水中健身运动改善中老年人桡骨、腰椎、股骨、跟骨骨密度,在效果表现为量的积累,预时长一年效果最佳,运动频率每周1-3次,每次35-60分钟。

Sorting out and merge the included literatures to expand the sample size,and quantitatively evaluate the influence of the aquatic on the bone mineral density,which devote to provide a scientific,effective and safe way to influence bone mineral density and reduce the risk of falling of the middle-aged and the elderly.A total of 1217 articles were searched in PubMed,CNKI and other databases with keywords and subject words,after screening,12 literatures were included.Compared with the control group,the influence of aquatic on bone mineral density of lumbar vertebrae,radius and calcaneus in middle-aged and elderly people was significant,while that of femur was very significant.Land resistance exercise had significant effect on lumbar bone mineral density,but had no significant difference on femoral bone mineral density.The aquatic can improve the bone mineral density of radius,lumbar spine,femur and calcaneus of middle-aged and elderly people.The effect is the accumulation of quantity,and the best effect is expected to last for one year.The exercise frequency is 35-60 minutes,1-3 times a week.
