Characteristics of changes in the level of resistance of mixed martial arts athletes to a stress stimulus in the conditions of different force load regimes

Abstract

The presented article is devoted to the study of the problem of developing effective strength training regimens for mixed martial arts athletes, taking into account the specifics of this sport and determining the level of resistance of their body and the manifestation of processes of long-term adaptation to a stressful stimulus of the appropriate nature. The purpose of the study was to study the characteristics of the change in the level of resistance of the body of mixed martial arts athletes under the conditions of the use of power load regimes with different parameters of volume and intensity. 75 athletes aged 19±0.7 years, who were divided into 3 groups, took part in the research. The following research methods were used: theoretical and methodological analysis of data from scientific and methodological literature, control testing of the development of maximum muscle strength of athletes, a method of quantitative assessment of the level of physical exertion in power sports, biochemical methods of controlling the concentration of cortisol in the blood serum of participants, a pedagogical experiment, mathematics - statistical methods of processing results. The results of the study indicate that mainly in the athletes of group 3, who during the 12 weeks of the study used a regime of high-intensity loads (Rа=0.72) under the conditions of anaerobic-lactate type of energy supply of muscle activity, we observe the most accelerated growth rates of the power capabilities of the pectoral m muscles on the background of the lowest load volume indicators in a separate set among the groups. At the same time, under the given conditions of training activity, the level of the body's resistance to such a stress stimulus of a force orientation is maximally increased in such a short period of time among athletes of the 3rd group. At the same time, in the athletes of the first group under the conditions of using the mode of low-intensity power loads (Rа=0.53), not only a minimal shift in relation to the investigated problem was detected, but also a fixed manifestation of compensatory reactions to the stressful stimulus.
