DYNAMICS OF HEART RATE ON STEPPED GROWING LOAD HAVE SKIERS IN THE PREPARATORY PERIOD
The article presents the research results of the analysis of the dynamics of heart rate on the step of increasing the load after the various meso-cycles training athletes of 15–16 years in the preparatory period. In the first phase of the study during the transition period there was testing on the Bicycle Ergometer with stepwise increasing load. The initial load was 27 watts, and every 2 minutes the load increased by 27 watts. At the end of each minute recorded heart rate. The second phase of testing was performed after the first meso-cycle of training, which was focused on the development of power endurance. The third phase of testing was performed after the second meso-cycle of training, which was aimed at the development of General endurance. The dynamics of average heart rate after the 1st meso-cycle of training found that the 1st and the 2nd phases of the load on the Ergometer are reliable and have not changed. In the subsequent 3 to 6, the load level can be seen significant decrease in average heart rate in athletes. This is due to the fact that the development of power endurance in the 1st meso-cycle of training improved aerobic capacity of the investigated muscles and has a positive impact on the health of the heart. After the 2nd meso-cycle of training in which the slope was placed on General endurance, heart function of the studied athletes 15–16 years of age also increased.
