Abstract

This study aimed to analyse how planning time effects peak knee valgus (PKVM) and internal rotation (PKIRM) moments using real-time (RT) and above real-time (ART) game-like video clips. 12 male Australian rules football players completed a modified sidestepping (SS) movement assessment. PKVM and PKIRM were measured across the weight acceptance phase of planned (PSS) and four unplanned SS conditions, increasing in video playback speed (UP100, UP125, UP150, UP175). No significant differences were found for PKVM or PKIRM between any SS conditions, however, the coefficient of variation in PKVM increased as the temporal constraints of the unplanned tasks increase. This study suggests that while mean group differences in PKVM may not be obvious, increased individual subject variation is evident as planning time decreases.
