运动引起心血管系统功能改变,使每搏输出量增加,心率加速,血压升高以及外周阻力降低。对心血管系统的调节机制,通过交感神经突触前膜释放去甲肾上腺素(NA)及肾上腺髓质释放肾上腺素(A)来实现。心血管
Exercise causes changes in cardiovascular system function, so that stroke volume output increased heart rate, blood pressure and peripheral resistance decreased. Regulatory mechanisms of the cardiovascular system are achieved by sympathetic presynaptic membrane release of noradrenaline (NA) and adrenal medulla release (A). Cardiovascular
