Specific characteristics of special endurance of skilled kayakers at 1000 m distance

Abstract

The new possibilities of estimating special endurance of rowers, specialize at 1000 m distance are shown. It is established that the assessment of special endurance requires a comparative analysis of the indices of cardiorespiratory system response and the energy supply of the athletes registered in the conditions of stable state of functional provision of special work capacity and in the conditions of latent (compensated) fatigue. Objective. To determine special endurance characteristics of skilled kayakers at 1000 m distance. Methods. Analysis of scientific literature, studies of ergometric and physiological indices, testing. Results. In the process of fatigue compensation, athletes with the highest indices of special work capacity (according to ergometric power of work in 90s test) increased consumption of O 2 and pulmonary ventilation response to the accumulation of C 2 (VE / CO 2 ); the ratio of O 2 intake and heart rate (O 2 / HR) decreased insignificantly. This indicates an increase in fatigue compensation response and its positive impact on the work capacity of rowers in the period of fatigue development. An increase in the range of individual differences in the indices of the responses of cardiopulmonary system and energy supply of work within the range of 31.0-55.1% indicates the need to search for rational ways of directed influence on functional capacities of rowers by training means. We are talking about the application of a system for monitoring and evaluating functional capacities of rowers to determine individual parameters of ergometric power and the duration of work under the conditions of latent (compensated) fatigue.
