Why the study?
Do voluntary and electrically induced isometric muscle contractions elicit cardiac acceleration via a muscle-heart reflex in humans?
Do voluntary and electrically induced isometric muscle contractions elicit cardiac acceleration via a muscle-heart reflex in humans?
The study provides strong evidence for a muscle-heart reflex in humans that causes instantaneous cardiac acceleration at the onset of exercise via vagal efferent pathways.
No takes yet. Share an insight, caveat, or question.
Demonstrates a rapid vagally mediated muscle-heart reflex at exercise onset; leaves open its relevance to clinical exercise testing or autonomic monitoring.
Hollander et al. (1975) studied this question.
