摘要
目的探讨运动对去卵巢大鼠腰椎抗压性能的影响。方法Sprague-Dawley大鼠随机分为假手术组、去卵巢手术组、雌激素治疗组和运动组,观察去卵巢大鼠经过3个月有氧跑步训练后第3腰椎抗压性能的变化。结果运动能使去卵巢大鼠的腰椎抗压性能略有提高,但运动组压力峰值和最大抵抗应力与去卵巢手术组比较,差异均无统计学意义(P＞0．05)。结论运动对骨质疏松大鼠力学性能的改善作用较微弱,对其骨的保护作用弱于雌激素。
Objective To compare exercise with other methods of maintaining the resistance of the lumbar vertebrae to stress. Methods Sprague-Dawley rats were randomly divided into a normal supplement group, an ovarectomized group, an estrogen supplement group and an exercise training group. All groups were subjected to 3 months of running training. Changes in the stress resistance of the third lumbar vertebra were observed. Results The exercise training improved the stress resistance of the lumbar vertebra in the ovarectomized rats slightly, but there was no significant difference between the changes in the various groups. Conclusions The effect of exercise in improving bone biomechanics was slight. The therapeutic effect of exercise training on osteoporosis was less than that of estrogen, but as the exercise training has no side effects on the uterus, it can be used safely.
