Abstract

This paper aims to investigate the differences in body composition among adolescent swimmers of different age categories, with special emphasis on the percentage of adipose tissue and muscle mass. The research included 70 respondents, 35 of whom were male and 35 female swimmers, divided into three age groups: early adolescence (10-12 years), middle adolescence (13-16 years) and late adolescence (17-19 years). Modern methods of bioelectrical impedance were applied to measure body composition, and the results showed statistically significant differences in the percentage of fat tissue and muscle mass between different age groups. These findings represent a significant contribution to the understanding of the physical development of young athletes and provide valuable guidance for sports training and planning the training process.

Key words: swimming, body composition , adolescents, physical development, sports training
