目的 :探索长期健身锻炼对老年妇女骨密度的影响及其可能的机理。方法 :实验对象为50岁以上绝经的妇女 ,采用SD -1000型骨矿物质含量测定仪测定臂骨矿物质含量(BMC)、骨密度值(BMD) ,血清骨钙素(BGP)、白细胞介素 -6(IL -6)水平分别采用放免法和酶联免疫法测定。结果 :健身锻炼组的妇女桡、尺骨骨矿物质含量及骨密度均显著大于对照组 ,且血清BGP和IL -6含量显著低于对照组。结论 :健身锻炼有利于提高老年妇女的骨密度 ,这可能与血清IL -6含量降低有关 ,提示积极参加体育锻炼可预防老年性骨质疏松症或推迟其发生。
Objective: To explore the effect of long-term fitness training on bone mineral density in elderly women and its possible mechanism. Methods: The subjects were over 50 years old menopausal women, using SD -1000 bone mineral content determination of arm bone mineral content (BMC), bone mineral density (BMD), serum osteocalcin (BGP), interleukin The level of IL -6 was measured by radioimmunoassay and radioimmunoassay respectively. Results: The radial and ulnar bone mineral density and bone mineral density of the women in the exercise group were significantly greater than those in the control group, and the contents of BGP and IL-6 in the exercise group were significantly lower than those in the control group. Conclusion: Physical exercise can improve the bone mineral density in elderly women, which may be related to the decrease of serum IL - 6 level. It suggests that actively participating in physical exercise can prevent or delay the occurrence of senile osteoporosis.
