Genu Varum, Change of Direction, and Reactive Agility in Youth Football Players
2. september 2026 opdateret af: Akdeniz University
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:
- Do football players with and without genu varum differ in COD and RA performance?
- 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.

Tidsramme |
|---|---|---|
|
Change-of-direction performance
Tidsramme: at basline
|
Change-of-direction performance will be assessed using the SpeedCourt system (Globalspeed GmbH, Hemsbach, Germany).
The test consists of a 14.5-m running course with four changes of direction.
Performance will be evaluated based on total completion time, with lower times indicating better change-of-direction performance.

Reactive agility performance
Tidsramme: at basline
|
Reactive agility performance will be assessed using the SpeedCourt system (Globalspeed GmbH, Hemsbach, Germany).
Participants will respond as quickly and accurately as possible to randomly presented visual stimuli and perform the required directional movements.
Performance will be evaluated based on total completion time, with lower times indicating better reactive agility performance.

Intercondylar distance and intermalleolar distance
Tidsramme: at basline
|
Lower-limb alignment will be assessed by measuring intercondylar distance (ICD) and intermalleolar distance (IMD) in centimeters.
ICD will be measured as the distance between the medial femoral condyles, and IMD as the distance between the medial malleoli, using a standardized measurement procedure.
