Особливості кореляційного зв’язку між зовнішнім стресовим подразником та адаптаційними змінами в організму спортсменів Mixed Martial Arts

Abstract

Topicality. One of the most important aspects in the field of sports is determining the appropriateness of the loads used for the adaptation capabilities of the athletes' bodies. This is a key element in both the training and competition process, which requires immediate correction and the development of effective training systems with long-term prediction of results, not only in mixed martial arts, but in all other sports as well. The Purpose of the Research. To study the peculiarities of the correlation between the parameters of the working weight of the projectile and adaptive changes in the body of mixed martial arts (MMA) athletes in the process of special strength training. Methods. 50 shock style MMA athletes aged 19±0,7 took part in the study. Two research groups were formed. The representatives of the examined groups used experimental regimens of training sessions during 3 months of strength training. Correlation analysis was carried out between parameters of projectile working mass (m) and biochemical indicators of blood, anthropometry, bioimpedancemetry, control testing of the development of maximum strength of athletes. The Results. In the athletes of the first group at all stages of the study, it was found that a constant strong positive relationship (r>0,70) is observed between the indicator of the working mass of the projectile (m=56–59 % of 1 RM) in the conditions of the regime of type A training loads (Ra=0,56) and the development of the maximum strength of leg muscles during the exercise «leg press on the block» (r=0,73), as well as the basal level of lactate dehydrogenase enzyme concentration in blood serum (r=0,72). The analysis of the results of the study obtained after 3 months of special strength training by the athletes of the second group of C-type training loads (Ra=0,74) indicate that the number of strong correlations has increased 9 times compared to the data found at the beginning of the experiment. It was established that the largest change in the level of correlations from moderate at the beginning of the study (on average r=0,57) to high after 3 months of training (on average r=0,87) occurred between the projectile working weight indicator and the results of the control testing the development of maximum muscle strength (chest muscles, shoulder and hip muscles) during control exercises. Findings. It was established that only among the athletes of the second group, who in the process of special strength training use the mode of training loads of type C (Ra=0,74), the correlations increase during 3 months of training, which indicates pronounced processes of long-term adaptation.
