Modern and methodic approaches to express-assessment of functional preparation of highly qualified athletes

Abstract

The purpose of the study was to experimentally verify the informativity and objectivity of the innovative method for assessing the fitness of athletes to improve the effectiveness of the medical and biological control and training process. The object of the study is a system of medical and biological monitoring of the functional fitness of athletes. The subject of the study is the degree of coherence of the indicators of functional preparedness, determined by direct (laboratory) and indirect (innovative) research methods. Participants. To assess the validity and representativeness of the innovative method for determining the level of functional preparedness and its individual indicators, 15 athletes aged 19-20 years old attended the British Student Sports Clubs. Results. The analysis of the data allowed to establish the high informative and objective nature of the developed innovative method for assessing the current level of functional preparedness, which was reflected in the high degree of coherence between the parameters of functional preparedness of the surveyed athletes determined by two different methods. It was shown that the mean values of absolute and relative values of all studied indices were not significantly different (p <0.05); for all indicators there was a strong correlation dependence; the magnitudes of the general error in the method of Blend-Altman did not exceed the marginal 10%; the value of the absolute difference between the values of all indicators of functional readiness was in the allowable range from 1.96 to+1.96 dB, and the coefficients of the linear regression equations did not exceed the limit values. In addition, the assessment of the reliability of the proposed method showed its undeniable representativeness. This was confirmed by the absence of significant differences between the results of the first and second consecutive tests, high correlation coefficients, minor variations in the coefficient of variation, and the general error of the Blend-Altman.
