Objective of the study is to improve the methodology of teaching motor skills.
Methods and structure of the study. To determine the duration of students' concentration, testing was conducted at the stage of motor skill formation. When teaching the two-handed overhead pass, in the preparatory exercise ‘catching the ball thrown by oneself with the hands in the correct position,’ the task was to move the thumbs as far back and down as possible. It is not rational to measure the total time until the movement structure is disrupted in this exercise due to the latent period during the throw and flight of the ball. The number of correctly performed repetitions (X mean) was counted. Loss of concentration was eliminated by failure to complete the task. The age of the test subjects was 9, 11, and 13 years. Gender was male. Number of subjects was 54 (n = 54).
Results and conclusions. In the process of testing the ability to concentrate among those engaged in the formation of motor skills, the following results were obtained for the duration of concentration among adolescents aged 9–13 years. At the age of 9, boys maintain a high level of concentration on average for 6 repetitions of a motor action. At the age of 11, boys maintain high concentration on average for 8 repetitions of a motor action. At the age of 13, boys maintain high concentration on average for 9 repetitions of a motor action.
It has been proven that the duration of the period of maximum concentration can be increased by short rest intervals aimed at switching attention. The dosage of load and rest periods, taking into account the ability to concentrate, seems rational and can be highlighted as a specific methodological technique.

Keywords: pedagogical process, technical training, motor skills, preparatory exercises, concentration, fatigue mechanism, sensory-analytical systems, dosing of load and rest, training effectiveness, methodological technique.
