Normalized system for assessing predisposition to different types of swimming

Abstract

The article presents the results of a study conducted in the period from 2021 to 2023, involving 147 athletes - swimmers. The following morphometric body build indices were selected for normalization and identification of children's predisposition to swimming in different styles: body mass index (BMI), relative arm length index (RALI), ARE index (ARE), relative leg length index (RLI), Scelia index (SI), relative shoulder width index (RWI), Pinier index (PI), Erisman index (EI). As a result of the research the following results were obtained: for the butterfly style the most informative indices are ARE, SSPI, IE; for the backstroke method - IODR, IODN, IS; for the breaststroke method: IODN, IS, SSPI; for the freestyle: BMI, ARE, IP, IODR. Quantitative normalization of the obtained indices was carried out to identify high and low level of predisposition to the above mentioned styles of swimming-82B0-4
