May heighten post-exercise event risk via accentuated sympatho-vagal outflow; leaves open causal role and relevance beyond healthy subjects.
Does exercise alter sympatho-vagal interaction in the recovery phase compared to rest in healthy subjects?
Higher sympathetic activity in the recovery phase of exercise is associated with augmented cardiac vagal activity, creating an accentuated sympatho-vagal outflow that may explain post-exercise cardiovascular events.
Tulppo et al. (2011) studied this question.
