Passport and biological age of young kickboxers aged 12-13 years and boys of the same age who do not play sports: a comparative analysis

Abstract

The purpose of is to determine the levels of biological development of young kickboxers aged 12-13 and boys of the same age who do not play sports. The study was conducted on the basis of the Children's and Youth Sports School «KHFTI» and the communal institution «Lyceum of Ruska Lozova» of the Dergachy District Council of the Kharkiv Region. 28 kickboxers (boys) of the group of pre-basic training of the first and second year of study and 30 boys of 12-13 years who do not play sports took part in the study. In the process of research, methods of analysis and generalization of scientific, educational and methodological and special literature on medicine were used - in order to establish the state of development of the researched problem. Empirical: pedagogical observation during training classes and lessons on physical education of students, anthropometric measurements, determination of biological age and methods of mathematical statistics. The calculation of the levels of biological development was carried out according to the criterion of K. Hirat. It is based on the analysis of height and weight ratios of the human body. Kickboxing athletes showed a lower level of biological development compared to non-athletic boys. The biological age is lower than the passport age in the group of athletes, the biological age is higher than the passport age in the group of boys who do not play sports. The study demonstrates the positive impact of systematic physical activity on reducing biological age and levels of biological development. This type of physical activity can be recommended to teenagers in building programs of optimal movement mode.
