Injury prevention

Document Type



Fourteen professional male football players undertook straight line run and sidestep cutting at 30° and 60° with standardised approach velocity on an approved football surface using standardised studded football boots. The relationship of simultaneous hip and knee kinetic and kinematic magnitudes and timings on potential non-contact ACL (anterior cruciate ligament) injury using inverse dynamics analyses by an eight camera gait analysis system synchronised with a force platform were determined. Early peak cutting hip abduction and internal rotation moments at 13-32% of stance and high hip abduction angles are related to later peak knee valgus moments and internal rotation moment values at 30-46% that can influence ACL injury. Early stance large hip abduction angles and valgus moments early should be targeted in injury training prevention.
