摘　　要：通过对耐力训练大鼠肾动脉的零应力状态下的张开角、形态学的变化研究,探讨耐力训练对肾动脉的张开角和形态结构的影响。结果表明耐力训练组大鼠肾动脉张开角与对照组相比明显减小(P<0.05);血管中膜、内膜厚度变化不显著(P>0.05);中膜面积显著减小(P<0.05),血管内径显著减小(P<0.001);而中膜/内径无显著变化(P>0.05)。因此,长期耐力训练后,肾动脉的生物力学特性和形态学结构出现了适应性变化。The study aims to discuss the influence of endurance training on the opening angle and morphology of renal artery through a study on the changes in the opening angle and morphology of renal artery of rats under zero stress state caused by endurance training. The result shows that compared with the control group, the opening angle of renal artery of the rats which receive the long-term heavy load endurance training has reduced greatly （P〉0.05）; changes in the thickness of the tunicae media and intima vasorum haven＇t been significant （P〉0.05）; the area of the tunicae media vasorum has decreased dramatically（P〈0.05）and the blood vessel diameter has become significantly smaiier（P〈0.001）. However, no distinctive changes have been found in the tunicae media vasorum diameter （P〉0.05）. Therefore, the biomechanics characteristic and morphology of renal artery appear adaptable changes over a long time of endurance training.
