Morphotypological characteristics of primary school children engaged in karate Kyokushin

Abstract

We use anthropometric methods and caliperometry to determine the features of the primary school children physique type involved in Kyokushinkai karate, and to identify the morphological selection criteria at the stage of sports development, the morphotypological indicators of 28 primary school children were studied (8 boys at the age of 7 years and 20 boys in age 10). The length and weight of the body, total, partial body dimensions, as well as the thickness of the subcutaneous fat folds were determined. Fat-free body mass, fat, muscle and bone components were calculated by the analytical method proposed by J. Matejko. Body proportions were established according to the classification of P.N. Bashkirov based on the percentage of the longitudinal and transverse dimensions of the body to its length. The somatotype was determined by the Heath-Carter method and was established on the basis of anthropometric calculation formulas. The obtained data characterizing the peculiarities of physical development, taking into account age and in the course of sports. Differences in the overall, component composition of the body in children of different ages under the influence of physical activity have been established. For children of primary school age (7 and 10 years old) who engage in Kyokushinkai karate, meso-ectomorphic and ecto-mesomorphic body types are characteristic. It is expressed in well-developed muscles and insignificant fat deposition with sufficient elongation of the body.
