【摘要】 目的观察衰老和运动训练对老年大鼠大脑皮层NO代谢水平的影响。方法以SD雌性大鼠为研究对象,通过无氧阈的测试,给予大鼠50%的小强度、70%的中强度以及90%的大强度训练12周。结果随着鼠龄的增长,大鼠大脑皮层NO的含量下降;长期小强度和大强度运动对NO无明显影响;长期中等强度运动后,大鼠大脑皮层NO的含量提高。结论长期适宜的中等强度运动可以改善大脑皮层的NO代谢水平。更多还原

【Abstract】 Objective To study the effects of aging and exercises on NO metabolism level in cerebral cortex of SD rats. Methods By testing the oxygen threshold,the rats were given 50% intensity、70% intensity and 90% intensity training for 12 weeks. Results Along with the NO content drop ped; the long-term low-intensity and the great intensity exercise do not have the obvious influence to NO content; After long-term medium intensity exercise,the NO metabolism level in cerebral cortex improved hancement. Conclusion Long term medium intensity exercise can improve the NO metabolism level in cerebral cortex of rats.更多还原
