Determinacy of pre-competitive heart rate regulation processes by personal characteristics of athletes

Abstract

The purpose of the article is to study the features of heart rate regulation in the pre-competitive period, depending on personal characteristics. Materials and methods: qualified and highly qualified athletes of various specializations (n = 50) participated in the study. The parameters of autonomic regulation were evaluated using the method of heart rate variability (HRV), carried out under pre-competitive stress conditions before city, regional and national competitions. The experiment was conducted according to the following scheme: the first measurement-recording HRV and personal characteristics on the day of rest (relative physiological rest), the second measurement-one hour before competitions (stress). The personal characteristics of the athletes were determined using the 16PF Cattell's questionnaire (form C) and the Spielberger's Test Anxiety Inventory. Results: the paper shows two types of HRV response to precompetitive stress in athletes, depending on the initial status of the body. The correlations between the personal characteristics of athletes with HRV indicators in the precompetitive period are established. Conclusion The personal characteristics of athletes participate in the formation of the specifics of the response of autonomic regulation to cardiac activity in the pre-competitive period.
