Genu Varum, Change of Direction, and Reactive Agility in Youth Football Players

The goal of this observational study is to compare change-of-direction (COD) and reactive agility (RA) performance between football players with and without genu varum and to examine whether lower-limb alignment is associated with these performance measures. The main questions it aims to answer are: 1. Do football players with and without genu varum differ in COD and RA performance? 2. Is lower-limb alignment associated with COD and RA performance in football players with and without genu varum? Football players with and without genu varum will undergo assessments of lower-limb alignment, COD performance, and RA performance. The study will compare performance between the two groups and examine the relationship between lower-limb alignment and performance measures.

Inclusion Criteria: * At least five years of football experience * Participation in football training at least five days per week * Voluntary participation in the study Exclusion Criteria: * History of lower extremity surgery * Current musculoskeletal injury affecting performance
