Reaction of the organism to repeated training loads, directed to improve the performance of the qualified rowers of China

Abstract

Purpose: The differences in the functional support of the rowers' performance during the four trails performed in the threshold zones of the load intensity are shown - in the zone of the aerobic (ventilatory) threshold, anaerobic glycolytic threshold, maximum O2 consumption, at the level of ergometric power of 115% VO2 max. High adaptive abilities of an organism to loads of relatively low intensity at the level of aerobicanaerobic transition are noted. In conditions of loads performed with higher intensity, close to the competitive activity of athletes in rowing, the degree of stress of the cardiorespiratory system increases, the speed of recovery processes decreases. To the greatest extent, the level of reaction decreases under conditions of accumulation of fatigue, typical of the second half of the distance. Participants. The study involved 38 athletes (men) aged 18–27 years old, candidates and members of the national team of Shandong Province, China. The studies were conducted in a special preparatory period at the center for training national water sports teams (Beihai, China). Results: The article shows the differences in functional support of rowers in the process of performing four trails in the threshold zones of the load intensity - in the zone of the aerobic (ventilatory) threshold, anaerobic glycolytic threshold, maximum O2 consumption, at the level of ergometric power of 115% VO2 max. Significant differences (p <0.05) were noted for the integral index of the response of the cardiorespiratory system - the training impulse in the process of fulfilling the last segments 1–2 and 3–4 of the trail, respectively - 5.15; 5.14; 4.77; 4.64. High adaptive abilities of an organism to loads of relatively low intensity at the level of aerobic-anaerobic transition were noted. In conditions of loads performed with higher intensity, close to the competitive activity of athletes in rowing, the level of cardiorespiratory system increases, the speed of recovery processes decreases.
