TENDENCY OF CHANGES IN EXERCISE TOLERANCE IN HURDLERS AT DIFFERENT STAGES OF TRAINING AND COMPETITIVE CONDITIONING
2017
The aim of the research was to assess the influence of training factors at different stages of sport conditioning of hurdlers on their exercise tolerance. Material and Methods. 12 highlyskilled and elite hurdlers were recruited to participate in the research. Mean age of the volunteers was 22.8 ± 0.25. Exercise tolerance in the examined hurdlers at each stage of trainingcompetitive cycle was assessed via estimation of metabolic equivalent recorded with the help of ergospirometry (SHILLER CARDIOVIT АТ-104 PC Ergo-Spiro stress system) using 3-stage continuous cardiopulmonary exercise test. Load stages were adequate to periods of warming-up, stable functional state, and anaerobic threshold excess. Recovery time and baseline indicators at relative rest were also recorded. Results. Comparison of main stages of training and competitive conditioning in exercise tolerance revealed that activity of metabolic processes in hurdlers depended on the volume of specific muscle work in the zone of anaerobic-alactic energy supply. Conclusion. The research reveals the distinct correlation between exercise tolerance under increasing physical load and the character of structural-essential component of main stages of training and competitive conditioning in hurdling.
