Features of technical training and sensorimotor reactions of different qualification football players taking into account lower limb asymmetry

The article shows the issues of motor asymmetry (MA) in modern football. In order to clarify the problem highlighting and opinions on the need of taking into account the asymmetry of the lower limbs in the process of Russian athletes' preparation the survey among experienced trainers of Children and Youth Sports School and professional clubs was conducted. The lack of specialists' awareness and single point of view about training specifics of «left foot» football players was determined, despite significant increase in their number in teams of different levels within the last decade. Comparative analysis of the structure of technical and tactical actions, made with the "leading" and "not leading" foot during competitive activity of skilled players of FC CSKA with different lateral preferences was conducted. The volume of technical and tactical actions, made by «right-foot» athletes with both feet is higher than by «left-foot». Herewith the use of subdominant limb is based on the appropriateness of the technical reception performance and is regulated by the player. Football players with dominant left limb have higher percentage of flaw while doing technical and tactical actions by the leading foot and lower one while using not leading. Age features of demonstration of motor asymmetry among athletes with different training experience were revealed. The most common motor phenotype of qualified adult players in Krasnodar region teams is «right», while among 6-8 year-old beginners lower limb asymmetry prevails. Positive annual performance dynamics of simple and complex sensorimotor reactions among young foot players was established. The results confirm the need for differentiation of content of football players' technical training considering motor asymmetry of the lower limbs in different age periods.
