SPECIFIC CHARACTERISTICS OF STABILITY OF FUNCTIONAL PROVISION OF SPECIAL WORKING CAPACITY OF DANCE ATHLETES

Abstract

Introduction. The relevance of research is due to the search for new opportunities to improve the functionality of dancers based on the study of specific characteristics of the cardiorespiratory system and energy supply. One of the ways to solve the problem is to improve the stability of the functional provision of special ability to work as a leading factor in demonstrating the skills of dancers in the standard program. The basis for the implementation of this area of ​​research is the formation of the regulatory framework of stability, its quantitative and qualitative characteristics that form a specialized direction of special physical training. The aim of the study is to identify specific characteristics of the stability of the functional support of the special ability of qualified athletes in sport dances. Material and methods: gas analysis, biochemical research methods, monitoring of competitive activity. Results. Characteristics of stability of functional support of special working capacity of dancers: at male partners VO2 max, VE, La in semifinals and finals of the standard program accordingly: 53.2 ± 0.5 ml · min-1 · kg-1 and 54.0 ± 0.4 ml · min-1 · kg-1; 116.3 ± 1.6 l · min-1 and 123.5 ± 1.5 l · min-1; 8.0 ± 0.4 mmol · l-1 and 13.0 ± 0.3 mmol · l-1. Differences in the specific performance of EqO2 during the quickstep and Viennese waltz were 3.0% in the semifinals and 4.2% in the final, respectively; EqCO2 - 4.4% in the semifinals and 5.2% in the finals; VO2 quickstep / VO2 in / waltz - 0.3% and 0.2%. The female partners VO2 max, VE, La in the semifinals and finals of the standard program, respectively: 48.8 ± 0.4 ml · min-1 · kg-1 and 49.1 ± 0.4 ml · min-1 · kg-1; 88.7 ± 1.6 l · min-1 and 111.0 ± 1.6 l · min-1; 6.7 ± 0.3 mmol · l-1 and 9.7 ± 0.4 mmol · l-1. Differences in the specific performance of EqO2 during the quickstep and Viennese waltz were 1.8% in the semifinals and 3.3% in the finals, respectively; EqCO2 - 3.1% in the semifinals and 4.0% in the finals; VO2 quickstep / VO2 in / waltz - 0.7% and 0.7%. Conclusions. The high level of power and stability of aerobic and anaerobic energy supply, the severity of the reaction of respiratory compensation of metabolic acidosis form the conditions for the implementation of the stability of functional support of special performance, which are presented to dancers in the middle and final part of competitive activities.
