摘要
目的探讨早年的体育活动对中老年后女性骨密度的影响。方法应用单光子骨矿物分析仪测定了长期从事体育活动的中老年妇女桡、尺骨骨矿含量(BMC)和骨密度(BMD)。结果运动组桡、尺骨BMC、BMD显著高于对照组;两组BMC、BMD均随年龄的增长而下降,对照组的下降幅度有高于运动组的倾向;运动员组BMC、BMD显著高于健身组;运动未中断组的BMC、BMD高于运动中断组。运动中断组BMC、BMD与健身组无显著性差异。结论参加体育活动越早,有可能获得的骨峰值越高;任何时候开始有规律的运动,对维持一定的骨量都有积极的作用。
Objective Research the effect of physical activity early on bone density of middle aged and old women.Method Ulna and radius bone mineral content (BMC) and bone mineral density (BMD) of middle aged and old women doing exercise over a period of time early were determined with Bone Mineral Analyzer.Results (1) the BMC and BMD of exercise group was higher than control group significantly; the BMC and BMD of the two groups decreased with age increasing and the BMC and BMD of the control group decreased faster than the exercise group.(2) compared with the continued exercise group, the BMC and BMD of discontinued exercise group was lower than it significantly. But there was no obvious difference with body building group.Conclusions (1) the earlier to exercise,the higher to get bone peak; (2) at any time begin doing exercise ,it might play active role to maintain fixed bone mineral amount.
