Control and Evaluation of the Strength Abilities of Primary School-Aged Karate Boys

Abstract

The purpose of this research is to provide a qualitative assessment of the development of strength abilities in 7-year-old boys using the results of complex control. Materials and methods. 32 boys of 7 years old took part in the research. The children and their parents were informed about all peculiarities of the research and gave consent to participate in the experiment. The following research methods were applied to solve the set tasks: analysis of scientific and methodical literature, pedagogical testing, and methods of mathematical statistics for processing research results. Results. Pearson’s correlation coefficient was calculated to estimate the closeness of interaction between parameters. The Spearman-Brown formula was used to determine the overall reliability (homogeneity) of the test. The test “Sit-ups in 30s from the supine position” and the test “Throwing a stuffed ball from a shoulder with the right hand” have the greatest number of numerous statistical interconnections (rxy = 0.701–0.851) of high significance (p<0.001) with other tests characterizing the structure of power fitness of the studied children. It is noteworthy that the test “Throwing a stuffed ball from a shoulder” is an exercise that involves different muscle groups of the trunk and upper and lower limbs. In its structure, it is similar to the technique of punching, so it is advisable to include it in the battery of tests to measure explosive power in martial arts. The 9-point scales of test evaluations were developed. Conclusions. The tests we tested considering the specific qualities necessary for karate are logically and empirically informative and reliable. They can be recommended for the control of different relatively independent types of power abilities of 7-year-old karate boys.
