Assessment of the level of a person's mastery of motor actions by the method of binary opposition "symmetry-asymmetry"

Relevance. The harmonic pair «symmetry-asymmetry» allows us to consider the causal relationships of such indicators as stability and variability when performing a motor action, which allows us to assess the quality of the implementation of motor skill and the possibility of its adaptation to changing environmental conditions. However, the realization of these possibilities is hindered by insufficient knowledge of the underlying patterns of motor skills formation in terms of the interaction of stability and variability, symmetry and asymmetry, insufficient knowledge of the application of this method of early identification of emerging problems in mastering motor actions. The article is devoted to the substantiation of the meaning of the binary interaction «symmetry-asymmetry» and rhythm for assessing the level of mastery of motor actions, the study of the generally accepted principle of the functioning of complex systems «symmetry-asymmetry» and the possibilities of using this opposition to assess and improve the quality of management of the process of formation of human movements. The purpose of the study is to substantiate the significance of the binary interaction «symmetry-asymmetry» and rhythm for assessing the level of mastery of motor actions. With the help of instrumental techniques and on the example of the motor action «squat» during the implementation of the stages and tasks of movement training, regular reflections of problems manifested in the form of a violation of symmetry and rhythm of movement were revealed. The possibilities of the knowledge obtained in this case for making managerial decisions related to the methodology and nature of training, and the probability of correcting motor actions are determined. In the course of the study, it is proved that the definition of the binary interaction «symmetry-asymmetry» and rhythm, as well as its violations in the process of implementing motor actions, is an effective way to assess the level of mastery of motor actions. In addition, it is proved that the study of the nature of the binary interaction «symmetry-asymmetry» and rhythm creates prerequisites for choosing a methodological basis for further improvement of motor action, provides information about the assimilation of the movement pattern and creates conditions for choosing the direction of correction of the technique of performing motor action.
