Abstract
The aim of the study was to determine the optimal dosage parameters for speed-strength exercises of the young sprinters. Research methodology and organization. For 12-17-year-old short-distance runners, the weights were determined to provide the maximum developed power. The following exercises were used: striding on the bench, pushing and jerking the barbell, pulling up on the bar. The study was carried out in September-October 2019 on the basis of the SBI of the Federal State Institution of Znamensky Bros. Track-and-Field Sports School "Youth of Moscow", 57 boys (youths) aged 12-17 took part in it. Research results. For each age period and in the analyzed exercises, the maximum developed power was determined. As the weight of the resistance increased at the beginning, the power indicators gradually increased, reaching the maximum value, and then decreased. On the basis of the results of the study at the first stage, the optimal values of weights were identified for each age range. At the second stage, the number of repetitions of this exercise was revealed without reducing the power indices. The analysis of individual indicators of the power of the exercise performance showed that the majority of the subjects showed the revealed generalized regularity, however, there were also discrepancies in the indicators. Conclusion. For each age period, the most effective modes of work for the development of speed-strength qualities in young sprinters were identified, revealing the maximum value of the power indicator and the number of repetitions of this exercise without reducing the power results. When performing the exercise, it is necessary not to strive to increase the weight of the weights, but it is important to increase the path and speed of movement.
Keywords: optimization, speed-strength qualities, exercises, power, load parameters.
