摘　　要： 目的:通过实验探索不同持续时间有氧运动对动脉粥样硬化大鼠的血液NO信号的影响以及一些相关调节因素的变化。结果:1)不同持续时间的有氧运动均可以显著提高血清NO水平和NOS活性,但是强度以上的有氧运动效果更为明显;30 min有氧运动虽然也升高了ET水平,但是60 min以上效果更为明显。2)动脉粥样硬化发展过程中L-Arg浓度变化并不明显,ADMA水平明显上升。有氧练习也不会升高血清L-Arg水平,但是较长时间的有利于降低血清ADMA水平,并有效改善L-Arg/ADMA比值,因此较长时间的有氧练习可能对NO的释放有明显的改善。结论:中等以上强度的有氧练习对改善动脉粥样硬化大鼠的O信号和相关的调节分子的效果最为明显。 Object：Explore the effect of different persistence time of aerobic exercise on serum NO signal and relative factory in artherosclerosis rat. Result： 1. All kinds of exercise intensities can notablely improve the concentration of serum NO and NOS activity. When the duration exceed 60 min, the effect of ET concentration increase is more obvious than 30 rain aerobic exercise. 2. The concentration of L - Arg is not chang during artherosclerosis developing. All kinds of duration exercise can not increase the L - Arg concentration. On the other hand, longer duration aerobic exercise can depress the serum concentration of ADMA and visible improve the ratio of L - Arg/ADMA. Therefore, the higher intensity of aerobic exercise can obviously improve the NO release of artherosclerosis rat. Conclusion： The effect of improve NO signal and relative factory in artherosclerosis rat is most obviously when those rats execute aerobic exercise over 60 min.
