Dynamics of maximum oxygen consumption in middle-distance runners in a one-year training cycle

Abstract

Purpose of the work: to study the dynamics of the indexes of maximal oxygen consumption in a one-year cycle of training in skilled runners who combine 800 and 400 m distances.
 Methods and materials: theoretical analysis and generalization of literary sources, analysis of documentary materials, submaximal Valunda-Schestrand test (PWC170), pedagogical experiment and methods of mathematical statistics.
 The research was conducted on the basis of the School of High School athletics of Kharkov. There were 5 boys and 5 girls who are 17-23 years old (4 - Candidates Master of Sports and 6 – athletes of the first category).
 In the course of the work it was established that the indexes of maximal oxygen consumption of athletes is changing with the growth of their training. It was found that the boys’ level of maximal oxygen consumption changes more significantly in the process of their training than in the process of girls’ training. This can be explained by lower aerobic productivity (power), which is reflected in lower results of women in sports with predominant manifestation of endurance. This factor explains the relative reduction of record results with increasing distance. It is marked that under the influence of training loads of a special preparatory stage of the preparatory period, the indices of maximal oxygen consumption of girls did not change.
