抗阻运动对更年期女性骨代谢的影响

目的：本研究试图通过对部分更年期女性骨代谢物含量的检测，探讨抗阻锻炼对更年期女性骨代谢的影响。方法：试验对象为华南师范大学20名健康绝经女教师，随机分为对照组（对照A组）、抗阻运动组（实验B组），进行为期9个月的实验。在运动干预前、3个月、9个月测定受试者正位腰椎骨密度，并抽取肘前静脉血，测定血清酸性磷酸酶、血清碱性磷酸酶、血钙、血磷等骨代谢指标。结果：1．对照组受试骨量丢失，骨密度下降（P〉0．05），抗阻运动组骨密度均增加（P〈0．05）。，2．实验前、3个月及9个月抗阻运动组的抗酒石酸盐酸性磷酸酶、血清酸性磷酸酶均有下降的趋势。实验前后，抗阻运动组自身对照显示差异具有显著性（P〈0．05）。3．对照组血清碱性磷酸酶的活性在实验前、3个月及9个月均无明显变化（P〉0．05），抗阻运动组实验前、3个月及9个月血清特异性碱性磷酸酶活性上升明显，具有显著性差异（P〈0．05）。4．对照组和抗阻运动组的尿钙与肌酐的比值均呈现下降的趋势（P〈0．05），抗阻运动组在9个月后与对照组相比差异具有显著性（P〈0．05），抗阻运动组在实验前后自身对比具有显著性差异（P〈0．05）。结论：抗阻运动对更年期女性骨密度及骨代谢具有良好的影响，可使骨密度显著增加（P〈0．05），血钙、碱性磷酸盐显著降低（P〈0．05）.

The Impact of Resistance Exercise on Bone Metabolism to Menopausal Women

Objective：This study attempts to detect the bone metabolism through some menopausal women with the resistance training. Methods： The subjects, who are 20 healthy postmenopausal women , were randomly divided into control group （ control group A）, the resistance movement group （ test group B）, for a period of 9 months experiment. Before intervention in the campaign, three months and nine months, took pre-elbow blood to measure serum acid phosphatase, serum alkaline phosphatase, Calcium, phosphorus and other indicators of bone metabolism. Results： 1. Phosphorus and calcium decreased significantly（P 〈 0.05） of the resistance exercise group of menopausal women. 2. It has a downward trend of tartrate-resistant acid phosphatase, the serum acid phosphatase before the experiment, three months and six months of the resistance movement group. Before and after the experiment, resistance exercise self-control group showed significant differences（ P 〈 0.05 ）. 3. The serum ALP activity of resistance exercise group was significantly increased（P 〈0.05）. The specific serum alkaline phosphatase activity increased significantly, with a significant difference before the experimental group, three months and six months in resistance movement group. 5. It showed a downward trend in the control group and resistance exercise group of calcium and ereatinine ratio（ P 〈 0. 05） , and compared with the control group, the exercise group after six months had significant difference （P 〈 0.05）. 6. h showed a clear upward trend in estradiol levels of the resistance exercise group after exercise. Conclusions：After 9 months of training, the ALP activity in resistance movement group increased, ACP activity decreased, show that the resistance movement against ALP, ACP.
