Hypothesis-generating for dual autonomic mechanisms of training bradycardia; should not yet change clinical practice.
Does a 5-week physical training period alter autonomic nervous system activity to cause bradycardia in previously sedentary subjects?
Short-term physical training induces bradycardia in previously sedentary individuals through a combination of reduced beta-adrenergic activity and increased parasympathetic activity.
Ekblom et al. (1973) studied this question.
