Pattern recognition: the effect of exercise performance modes on the effectiveness of teaching the vault to 8-year-old boys

Background and Study Aim. The study purpose was to determine the effect of exercise performance modes on the effectiveness of teaching the vault to 8-year-old boys.  
Materials and methods. The study participants were 32 boys aged 8 who were divided into 4 groups of 8 pesons. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The pedagogical experiment investigated the effect of the number of sets (х1), the number of repetitions in a set (х2), and a 60-second rest time on the change in the gain in the level of proficiency of 8-year-old boys in straddle vault over the buck. A method of algorithmic instructions was used in the training. The participants proceeded to the next exercise after three successful attempts. 
Results. Statistical analysis of the significance of the discriminant functions showed that the first function explains 81.2% of the data variation and has a high canonical correlation value (r = 0.751).  The first function has a high discriminative ability (λ = 0.332, p < 0.021) and can be used to classify the modes of physical exercise performance in the process of formation of motor skills. 
Conclusions. The use of multivariate statistics makes it possible to determine the structure of the training program, confirm the effectiveness of the selection of motor tasks, and classify the modes of physical exercise performance during the training process. The best mode of physical exercise performance in teaching the vault to 8-year-old boys is 12 sets of 3 repetitions with a rest time of 60 seconds.
