# " '有氧能力:''最大有氧能力随有氧训练而增加。静止Vo2是稳定的,在给定的工作负荷下Vo2也是稳定的。这些变化是特定于训练肌肉的。# ''心输出量:'''最大CO增加,而静息CO稳定。静息SV增加,静息HR相应降低。 # '''Heart rate:''' Resting HR decreases with aerobic training and is lower at any given workload. The maximum HR is unchanged. # '''Stroke volume:''' SV increases at rest and is maintained at a lower HR, resulting in a lower RPP for a given level of exertion. # '''Myocardial oxygen capacity:''' Maximum Mvo2 usually does not change, but at a given workload, Mvo2 decreases with training. This reduces episodes of angina. # '''Peripheral vascular resistance (PVR):''' Aerobic training reduces arterial and arteriolar tone, thereby decreasing cardiac “afterload” and PVR. The reduction in PVR results in a lower RPP and a lower Mvo2 at a given workload and at rest.
