The aim of the study was to determine the effect of the number of repetitions on the effectiveness of the process of learning to throw a small ball to boys 9 years old.
Materials and methods. The study involved 27 9-year-old boys, who were divided into three groups of 9 people at random. The effect of the number of repetitions on the effectiveness of the process of learning to throw a small ball at a target in 9-year-old boys was studied. The pedagogical experiment studied the effect of 6, 12 and 18 repetitions with a rest interval of 60 s on the increase in the level of learning exercises of boys 9 years old. The materials of the study were developed in the program of statistical analysis – IBM SPSS 20. In the process of discriminant analysis, a prognostic model was created for belonging to the group.
Results. Discriminant analysis allowed to determine the influence of the number of repetitions on the effectiveness of the formation of skills of throwing a small ball into the goal; to answer the question of how significantly the modes of repetition differ in the effectiveness of the formation of motor skills, to which class the object belongs based on the values of discriminant variables.
Conclusions. Based on the analysis of the centroids of the groups, it was determined that 18 repetitions of the exercise (6 approaches 3 times with a rest interval of 60 s) has a significant impact on the increase in the level of learning in physical education lessons. The results of group classification show that 63.0% of the original grouped observations were classified correctly.
