Age-related physical and performance changes in young swimmers: The comparison of predictive models in 50-meter swimming performance

Introduction: The purpose of the study was to investigate age-related anthropometric and motor performance changes over time their contributions swimming style-specific in young different chronological age swimmers. Material Methods: conducted on a total forty swimmers who were divided into 2 groups. Anthropometric meas-urements executed from 12 body parts, composition analysis determined by using skinfold method. tests performed for assessment standing horizontal jump, handgrip strength, flexed-arm hang sit-up, flexibility, aerobic endurance, speed, agility, balance. Simple Linear Regression build models each styles. Results: All indicated that endur-ance significantly predictive variable all styles (p < 0.001). results predictors changed depending upon pro-gression style Conclusions: effect many variables is seen be more evident following periods based increase age. Aerobic endurance common shows effectiveness both groups
