Formation of Functional Orientation of the Preparation of High-Class Rowers for Major Competitions

Abstract

Introduction. The reserve for increasing the functional support of the special working capacity of rowers is the search for new opportunities for the regulation and stimulation of functions that ensure the speed of deployment and the achievement of reaction limits, the stable development of functions in the process of increasing and compensating fatigue. Matherial and methods: gas analysis, measurement of blood lactate concentration, ergometry (Concept «ErgRowing»). Factor and correlational statistical analysis. Results: Three factors are singled out, which together form a specialized focus of special physical training. The share of the first factor in the total variance was 34.8%, the second – 18.0%, the third – 14.1%. The first factor includes the characteristics of the power of aerobic energy supply and the reaction of the cardiorespiratory system to the development of acidosis at the beginning of the distance and during the steady state period. The second factor is based on the assessment of the stimulation-influenced degree of lactic acidosis, at which the athlete reached the maximum consumption of O2. The third factor is based on the assessment of the anaerobic reserve in the second half of the distance, its role in the formation of excess (buffer) CO2, its compensation (EqVCO2) in the conditions of fatigue development. Conclusions. The necessity of using modes of training loads aimed at stimulation of neurodynamic functions of the body, implementation of "acute" hypoxia, simulation of physiological states associated with varying degrees of influence of hypoxia, hypercapnia, lactic acidosis is substantiated. Special modes can be used during warm-up, additional (to the main classes) training sessions during the daily training cycle.
