Abstract

The possibility of applying the method of gas discharge visualization (GDV) for the rapid assessment of psycho-physiological readiness of athletes for the upcoming competition was investigated based on the results of the Russian national sledge hockey team at international tournaments. Significant correlations between GDV parameters of athletes and efficiency of their performances in competition was found.

 

Introduction

The development of methods allowing to predict the performances of athletes at the competition is the most important and ambitious task in sports. The presence of such an effective method could help coaches to make the right choice of players for the upcoming tournament and could significantly improve the team performance at the competitions.

People and in particular athletes are the most complex energy and information systems whose state depends on a number of factors. Quite often even professional athletes happen to perform poor, and if this athlete is a member of the team, this may lead to bad performance of the whole team. The reason for the poor performance of a player is determined by his/her poor physiological condition, which may affect such seemingly not related to the professional activity factors as turmoil in his personal or family life, emotional exhaustion from other kinds of activity, poor diet, overtraining in the preparatory phase to the competition, etc.

Gas-discharge visualization method (GDV) for the diagnosis of the human condition, actively developed in recent years in the world and especially in Russia to determine the psycho-physiological state of athletes takes into account the influence of many negative factors to the psychophysiological state of an athlete. These peculiarities of the GDV technique makes it an invaluable diagnostic tool in sports. Other advantages of the GDV technique include ease of use, noninvasive and very short time for analysis, which is very important in the case of sport applications, since athletes often emotionally overwhelmed at the competition and do not have enough time and energy for long and complex laboratory studies, which can further overload their emotional state.

This article is a continuation of a series of papers [1-3] on the application of the Gas Discharge Visualization (GDV) technique for determining the psycho-physiological state of athletes. In previous papers we discussed the use of GDV to determine the effect of sports training on athletes. This article examines the possibility of evaluation of competition efficiency of individual athletes based on GDV method data.

Methods

GDV method allows rapid assessment of the energy potential (EP) and the level of stress (SL), which together characterize the psycho-physiological state of athletes [1-3]. Parameter EP is ranging from 0 to 100 Joules and characterizes the energy level correlated with psychophysiological state of an athlete. High EP values ​ indicate a high level of energy reserve and a high degree of psycho-physiological readiness of the athlete. The parameter SL reflects the level of physiological stress and is measured in relative units from 0 to 10, where 10 units correspond to the maximum level of stress.
