Effects of exercise training intensity on cardiac autonomic regulation in habitual smokers

摘要

BackgroundThe sympathoexcitatory effects of cigarette smoking cause an autonomic imbalance that may lead to cardiovascular disease. Aerobic training improves autonomic function by developing cardiorespiratory fitness; however, it is still uncertain whether aerobic training ameliorates the compromised autonomic modulation in smokers. This study aimed to investigate the effects of 8weeks' aerobic training at different exercise intensities on autonomic regulation in habitual smokers.
