Features of the effect of prolonged running loads in athletics arenas on the formation of a motor stereotype in athletes

The relevance of this study is due to the need to study the problem of asymmetry of the structure of running movement, which forms a motor stereotype in athletes with prolonged running load in indoor arenas in regions with extremely cold climates. A comparative analysis of statistical data on the sports results of long-distance runners of the past years, when there were no sports facilities in Yakutia, with the results of athletes who have all the conditions for year-round training, shows a paradoxical decrease in sports performance in the latter. The assumption is put forward about the negative impact on the growth of sportsmanship of a specific motor stereotype that is formed in runners when performing long running loads in athletics arenas. The aim of the study is to identify functional and structural asymmetries of the body in athletes performing long running loads in the arena. Research methods. As part of the study, the following methods were used: analysis of scientific and methodological literature on the impact of an external factor on postural control and coordination ability; processing of static data on the sports results of the leading stayers and marathon runners of the republic in different periods; conducting anthropometry, dynamometry and stabilometry in the subjects; mathematical statistics. The results of the study. It has been established that long running workouts with repeated numerous bends on the turns of the arena during the long winter, place increased demands on the postural control system with the development of functional and structural asymmetries of the body, which have a negative impact not only on the growth of athletic performance, but also lead to injuries and diseases of the musculoskeletal system. Conclusion. In order to prevent the formation of a motor stereotype in athletes performing long running loads in the arena, it is recommended to conduct further research in order to develop a training methodology taking into account the influence of the circular trajectory of running movement on the development of speed and strength qualities and coordination abilities of athletes.
