Abstract
The purpose of this study was to investigate the effect of soccer specific functional fatigue on hip and knee

joints angles during landing in professional players.15 soccer players with at least 2 years experience in

Kerman soccer clubs were selected randomly. To evaluate the lower extremity kinematics following

jumping and soccer specific- heading, three cameras (with50Hz) were used. To cause fatigue in subjects,

specific functional protocol similar to specific bangsbo soccer was used and Quantic sport v21 soft ware

was administrated for kinematic analysis of the recorded films. To statistical analyzing of data, descriptive

statistical methods, and paired-t test were administrated at α=0.05.Finding revealed that hip and knee

angles in sagittal and frontal plane in landing is influenced by functional fatigue. This results has been

reducing knee and hip flexion angles and increased varus in knee joint. Results demonstrated a more

erect landing posture due to a decrease in hip and knee flexion angles in the post fatigue condition.

However, functional fatigue significantly decrease lower extremity control ability in male soccer player

during landing.
