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

Does Genu Varum Influence Change of Direction and Reactive Agility Performance 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:
