Exercise training improved blood flow velocity and autonomic nervous activity

The present study aimed to investigate non-invasively the effects of a short-term 4 week aerobic training program on the resting common carotid artery (CCA) blood flow velocity waveforms and autonomic nervous activity in young sedentary healthy subjects. It was hypothesis that training-induced the e...

Training exercise-induced the significant enhancement of all blood velocity waveforms is associated with decreasing of heart rate at rest.
