The aim of the proposed study is to reveal the correlations between the dynamics of
Respiratory Rate (RR) and Heart Rate (HR) during intermittent physical work at maximum …

Dynamic study of heart rate variability and dispersed cardiac mapping of 11 students-
athletes, aged 20-24, using apparatus Ekosan-2007 was conducted during 15 months. The …

Patients with cardiovascular disease show autonomic dysfunction, including sympathetic
activation and vagal withdrawal, which leads to fatal events. This review aims to place …

PURPOSE In order to investigate nonfunctional overreaching (NFOR) related adaptations in
the autonomic nervous system, heart rate variability (HRV) was examined in a professional …

Background Long term endurance training, as occurring in elite athletes, is associated to
cardiac neural remodeling in favor of cardioprotective vagal mechanisms, resulting in resting …

Stress is a psychophysical condition that causes an impairment in athletes' performance by
causing an increase in sympathetic activity and an autonomic imbalance. The current …
