The major goals of this study were (1) to determine consistency of autonomic response modes to different laboratory stressors, and (2) to evaluate the strength of the association between autonomic response modes and ambulatory heart rate and variability. ...
We examined the effect of training state on cardiac autonomic control in a naturalistic setting. Twenty-four vigorous exercisers were compared to age- and sex-matched sedentary controls. The regular exercisers were subjected to a 6-week training program ...
Neurocardiology has shown that the dynamic performance of the heart is strongly influenced by the brain, including the cerebral cortex. Neural control is mediated by sympathetic and parasympathetic fibers innervating the pacemaker, conductile, and ...
