Comparative Study of Morphological Parameters Between Female Swimmers from South-East and North-East of Algeria (12-13 years old)

Performance variations throughout a swimmer's career result from the interaction between training and genetic and environmental factors. Our study aims to compare several morphological parameters (height, weight, body composition) between two groups of young swimmers from the Northeast and Southeast of Algeria. These two geographical regions may present significant differences in genetics, climate, and environment, which could influence the swimmers' morphological characteristics and performances. The goal is to analyze how these differences may impact their performance levels. Body measurements were taken using a bioelectrical impedance analyzer, and performances in the 50m and 400m freestyle were recorded in a sample of 26 competitive swimmers aged 12-13 years: 13 from the Northeast (Constantine/Sétif) and 13 from the Southeast (Biskra/Ouargla). The results show that swimmers from the Northeast have significantly greater height and weight, which advantages them in the 50m and 400m freestyle events compared to their Southeast counterparts. However, no variations were observed in muscle mass, fat mass, and body mass index
