Background and Study Aim: Mass sports and sports events have a decisive influence on the formation of a healthy lifestyle of schoolchildren. Kyokushin karate can be used both as a sport, self-defence and as a health system for all ages. The purpose of the study was the knowledge about the peculiarities of teaching 10-year-old boys the technique of kicks in kyokushin karate based on an innovative methodological approach.
Materials and Methods: Boys aged 10 years (n = 32) took part in the study. The boys performed a series of tasks in accordance with two training programs: techniques of front kicking (mae-geri); roundhouse kicking technique (mawashi-geri). The method of algorithmic instructions was used in the learning process. A discriminant analysis of learning outcomes was conducted.
Results: Statistically significant boys mastered motor tasks of 1-5 series of training tasks of mawashi-geri (p<0.05). Eigenvalues indicate that the canonical function is highly informative (r = 0.938); analysis of Wilks' Lambda indicates the statistical significance of the canonical function. The values of the centroid coordinates for the two groups indicate significant differences in the learning of mae-geri and mawashi-geri. Eigenvalues analysis shows that the first canonical function explains the variation of results by 84.9%, the second function by 10.7%, and the third function by 3.8%. Canonical correlation values indicate that the first three functions are highly informative (r1 = 0.960; r2 = 0.772; r3 = 0.585). The analysis of canonical functions indicate the statistical significance of the first and second canonical functions (λ1 = 0.019; p1 = 0.001; λ2 = 0.244; p2 = 0.001). The first, second and third functions have a high discriminant ability and value in the interpretation of the general population .
Conclusions: Discriminant analysis allowed to determine how reliably the effectiveness of learning the technique of mae-geri and mawashi-geri differs among juvenile karate athletes. Structural coefficients of the discriminant function indicate that the effectiveness of the training program is determined by the selection of a series of learning tasks and the mode of their implementation. The boys have higher mastery of the mawashi-geri technique. The most significant difference in the quality of these learning tasks is also observed between the modes of exercise. A universal option for learning a series of tasks of the mae-geri and mawashi-geri training program for boys aged 10 is the second mode of exercise: 3 approaches with a rest interval of 60 seconds.
