| 摘 要： | 首先对心率变异性（HRV）和动脉压力反射敏感性（BRS）的测试分析方法进行了选取和改进,然后以正常大鼠为实验对象,观察比较尾动脉血压、脉搏、左室内压、心肌收缩力、心率变异性、动脉压力反射敏感性等指标在8周中等强度游泳运动组大鼠和和安静对照组大鼠之间的差异,旨在分析长期参加有氧运动对心血管自主神经调节功能的影响,为心血管自主神经平衡状态发生改变提供实验证据。研究发现,与对照组大鼠相比,运动组大鼠心肌出现肥大、心脏泵血功能增强、心交感神经介导的动脉压力反射敏感性升高、心迷走神经介导的动脉压力反射敏感性未受影响、心交感神经紧张性变异和心迷走神经紧张性变异程度均增加。研究结果提示,长期有氧运动可增强心血管自主神经的调节功能,使交感神经和副交感神经的协调与对抗关系在一个更高的功能层面上建立新的平衡。

| Abstract: | The authors first selected and improved the methods for testing and analyzing heart rate variability(HRV) and arterial baroreflex sensitivity(BRS),and then used normal rats as their experimental subject to observe and compare the differences of such indexes as caudal arterial blood pressure and pulse,internal pressure of left ventricle,myocardial contraction force,HRV and BRS between the rats in the 8-week medium intensity swimming exercise group and the rats in the calm control group,so as to analyze the effect of long-term aerobic exercise on the modulating function of cardiovascular autonomic nerve,and to provide experimental evidence for the change of the balanced state of cardiovascular autonomic nerve.The authors revealed the following findings: Compared with the rats in the control group,the rats in the exercise group had myocardial hypertrophy,boosted cardiac blood pumping function,increased BRS mediated by cardiac sympathetic nerve,unaffected BRS mediated by cardiac vagus nerve,and increased level of variability of tonicity of cardiac sympathetic nerve and cardiac vagus nerve.These findings suggest that long-term aerobic exercise can boost the modulating function of cardiovascular autonomic nerve,and enables the harmonizing and counteracting relation between sympathetic nerve and parasympathetic nerve to establish a new balance at a higher functional level. |
