摘　　要：目的为了探讨每次锻炼时间长短对老年男性骨密度和平衡能力的关系。方法选取苏南地区200名60岁以上老年男性中每周锻炼3~4次的87名为研究对象,采用单光子吸收法(SPA)和平衡仪系统对其骨密度(BMD)和平衡能力(Fall Index)进行检测,结果采用SPSS17.0分析处理。结果 (1)对于老年男性来说,每周3~4次体育锻炼,每次锻炼时间控制在45 min^1.5 h,无论对延缓机体BMD的下降还是提高自身的平衡能力方面,都是最优的;(2)有跌倒史(骨折史)的老年男性平衡能力比无跌倒史的差,同时前者BMD也明显低于后者。结论有跌倒史老年男性更加容易跌倒并且更容易有骨折风险,在体育锻炼中要十分注意。切忌只关注曾经跌倒受伤、骨折部位而忽视其它身体部位的风险,定期检查。Objective To investigate the relationship between different exercise duration on bone mineral density （ BMD） and balance ability in elderly men.Methods Eight-seven men, out of 200 elderly men over than 60 years old in south Jiangsu, who exercised 3-4 times per week, were selected in this study.BMD of all the subjects was detected using single-photon absorptiometry （ SPA） .And the balance ability （ Fall Index） was measured using the balance system.All the results were analyzed using a SPSS 17.0 software.Results For the elderly men, 3-4 times physical exercise per week and 45 min to 1.5h per exercise time is the best not only for delaying the decline in BMD but also for improving their balance ability.The balance ability in the elderly men with a history of fall （ fracture history ） was worse than that in those without a history of falls, and BMD of the former was also significantly lower than that of the latter.Conclusion The elderly men with a history of fall are more easily to fall and have high risk of fractures.So, they should pay much attention during the physical exercise.We should not only concern the history of fall and the fracture sites, but also pay attention to the risk of other parts of the body and regular inspection.
