Pattern Recognition: Effectiveness of Teaching Boys Aged 15 a Cartwheel

Abstract

The purpose of the study was to determine the impact of the number of repetitions on the effectiveness of teaching boys aged 15 a cartwheel. Materials and methods. The study participants were 20 boys aged 15. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of trainingtasks; pedagogical experiment, methods of mathematical statistics, discriminant analysis. Results. The assumption was made about a significant influence of the modes of alternating exercise repetitions and the rest interval on the effectiveness of motor skills development in boys aged 15. The study found that 6 sets 1 time each with a rest interval of 60 s are more effective than 6 sets 2 times each with a rest interval of 60 s when teaching the ability to assess movement performance by time (p < 0.001). And with the first exercise mode, fewer repetitions are needed to master the entire cartwheel. This is due to the fact that differentiation of time characteristics requires immediate information about the movement performance after each repetition. Conclusions. Based on the analysis of group centroids, it was found that 6 repetitions of the exercise (6 sets 1 time each with a rest interval of 60 s) significantly influence the cartwheel skill development in boys aged 15 during physical education classes. The results of group classification show that 95.0% of the original grouped observations were classified correctly.
