Purpose. To determine the impact of exercise modes on the effectiveness of teaching girls aged 14 the cartwheel.
Materials and methods. The study participants were 20 girls aged 14. 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 training tasks; pedagogical experiment, methods of mathematical statistics, discriminant analysis.
Results. The study found that statistically significant differences in the number of repetitions were observed in performing all series of training tasks, except the third one (p < 0.05). The girls aged 14 who used the first mode (6 sets 1 time each with a rest interval of 60 s) needed fewer repetitions to master the movements of the first, second, fourth, fifth, and sixth series of tasks (p < 0.05). The girls aged 14 who used the second mode (6 sets 2 times each with a rest interval of 60 s) needed fewer repetitions to master the movements of the third series of tasks (p < 0.05).
Conclusions. Discriminant analysis made it possible to determine the impact of the number of repetitions on the effectiveness of developing the cartwheel skill in girls aged 14.
Based on the analysis of group centroids, it was found that exercise modes significantly influence the cartwheel skill development in girls aged 14 during physical education classes. The results of classification of the groups show that 100.0 % of the original grouped cases were classified correctly.
