Study of qualified cyclists movements’ coordination structure in period of overcoming fatigue during differently oriented trainings
Abstract
Purpose: to study special aspects of pedaling structure and create diagnostic models of cyclists movements’ coordination structure under fatigue in differently oriented trainings. Material: in the research 18 elite sportsmen participated. Sportsmen fulfilled training programs on ergo-meter, directed on development of speed-power potentials and endurance in anaerobic and aerobic work. Results: it was found that in period of fatigue overcoming dynamic shocks in applied efforts disappear and the picture of bio-dynamic components becomes smoother. With it, relative usage of efforts’ horizontal components increases. In period of evident fatigue variability of movements’ kinematic characteristics and integrated bio-electrical activity of the tested muscles increase; cyclists’ efficiency reduces. Conclusions: distinctions in movements’ structure of cyclists in period of fatigue overcoming witness about certain tendency to transition from impulse-type pedaling to circular type. It pre-conditioned increase importance efforts’ components and effectiveness of their usage.
