THE EFFECT OF MAXIMUM ALACTIC PERFORMANCE ON ELITE CROSS-COUNTRY FEMALE SKIERS AT VARIOUS DISTANCES

Abstract

Aim. The paper aims to identify the effect of maximum alactic performance on the athletic success of elite cross-country female skiers during races at various distances in 2017–2018. Materials and methods. The correlation between maximum alactic performance and athletic success in ski races was found by processing the data of 18 female skiers aged between 20 and 27 years (Candidates for Master of Sport, Master of Sport). Our examination involved the assessment of speed qualities and maximum alactic performance in a series of cycle ergometer exercise tests. The results obtained were analyzed together with the results of the principal competitive events of the last year of the Olympic cycle (all-Russian ski race in Tyumen, Russian Cup Final, 2018 Winter Olympics, Championship of Russia). Results. The correlation analysis of the studied parameters and the results of the principal events of 2017–2018 confirmed that athletic success at various distances mostly depended on the relative value of maximum alactic performance, which reflected the state of regulatory mechanisms and the balance between body dimensions and its mechanical performance. Conclusion. The results of the study allowed to identify the existing patterns of speed qualities and maximum alactic performance depending on the features of competitive events and to develop the list of parameters, which demonstrated the most significant correlation with athletic success in the main competition of the Olympic cycle and at the final stage of athletic preparation.
