Influence of resistance exercise on autonomic nervous system and sleep

Abstract

Physical activity changes our body in many aspects, including autonomic regulation of cardiovascular system and thermoregulation, changes in metabolism, secretion of hormones and, as a consequence, mental changes. Acute effect of physical effort is increased sympathetic activity leading to condition known as ''fight or flight'' which includes tachycardia, tachypnea, blood pressure increase, pupil dilatation and increased attention. Parasympathetic activity is increased between series of trainings, during the resting state, and its effect is often referred to as ''rest and digest'' state. It includes increased salivation, drop in heart rate, bronchoconstriction, myorelaxation and pupil constriction. There are other factors responsible for the influence of exercise on our body. Good feelings and better memory after exercise are caused by secretion of various compounds, such as BDNF, dopamine and endorphins, as well as blood flow, leading to the use of exercise as therapeutic method but also as an agent of addiction. Sleeping is also altered by physical activity directly through nervous system and indirectly through metabolism and hormones. There are various types, aerobic and resistance, and frequencies of physical activity that can be used as treatment of many disorders and states. In this article we will discuss multiple benefits of resistance training on autonomic nervous system function and sleep.

Lifestyle Modification for Enhancing Autonomic Cardiac Regulation in Children: The Role of Exercise

“…One lifestyle modification for enhancing ANS regulation in children is proposed to be via the increase in appropriate exposure to exercise, which has been shown to benefit overall health and wellbeing [13]. Moreover, low PA participation appears to be associated with decreased PNS activity/cardiac vagal tone and increased prevalence of diseases associated with cardiac autonomic neuropathy (i.e., cardiovascular disease, DM, hypertension) [14,15,16].…”
