Abstract:
The present study examined the association between behavioural dimensions of self-regulation and respiratory sinus arrhythmia (RSA), a marker of cardiac autonomic functioning in a sample of preschool children in the United States. Sixty-six children's emotion- and cognitive-oriented dimensions of self-regulation were examined with respect to changes in RSA (reactivity and recovery). Results showed that children's recovery RSA, which indicates the ability to return to homeostasis, but not reactivity, was significantly associated with the cognitive-oriented self-regulation.

Self-Regulation
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Pathophysiology of Cardiac Performance
Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
