Abstract

Purpose: study of peculiarities of heart rate variability system in excellent athletes with different level of stress resistance. Material: 22 excellent athletes, members of the Vietnamese National Team Karate in the research. The level of stress resistance (stress tolerance) was determined by the results of test called “Stress Test” The athletes were divided in two groups according to level of stress resistance. Were used the cardiac monitor «Polar RS800CX» for studied of heart rate variability. Results: It revealed the increasing of level of stress resistance related with improving the system of autonomic regulation of heart rate in excellent athletes. This reflected by relaxation of level of tension and activation of parasympathetic part of autonomous nervous system. Were revealed the bigger meanings of LF/HF in athletes with average level of stress resistance for concerning to athletes of high level of stress resistance indicates the amplification of sympathetic and weakening of parasympathetic link of autonomic nervous system [1]. The athletes with high stress resistance level has high of level of heart rate variability and low of centralization of heart rate regulation for compared to athletes with average level of stress resistance.
