The effect of rhythm training on the motor coordination abilities of 8-12-year-old freestyle swimmers.

This study aims to evaluate the effect of rhythm training in the early coordination development and to find out its role in the transfer of specific performance in young swimmers. Eighty young swimmers aged eight to twelve were divided randomly into a control group (CON,  = 40, M/F=17/23) or an experimental group (EXP,  = 40, M/F=19/21). A total of 72 swimmers completed all the training programs and tests included in this study (CON,  = 35, M/F=15/20; EXP,  = 37, M/F=16/21).

Construction of an anthropometric discriminant model for identification of elite swimmers: an adaptive lasso approach.

Background: Anthropometric characteristics are important factors that affect swimming performance. The aim of this study is to build a discriminant model using anthropometric factors to identify elite short-to-medium-distance freestyle swimmers through an adaptive Lasso approach.

Methods: The study recruited 254 swimmers (145 males and 109 females) who were divided them into elite (aged 17.

Hematological, Hormonal and Fitness Indices in Youth Swimmers: Gender-Related Comparisons.

This study objective was to evaluate gender differences in hematological, hormonal and fitness variables among youth swimmers and to explore relationships between erythrocyte indices and aerobic and anaerobic capacity. 137 girls and 171 boys participated in the study and were divided into three groups based on their training experience. Blood samples were obtained to determine red blood cell counts, hemoglobin concentration, hematocrit, and plasma erythropoietin and testosterone levels.
