Abstract

This study investigated adaptations in change-of-direction (COD) movement strategies throughout a sequence of maximum-speed CODs in an on-field testing scenario that involved complex decision making and limited time for motor preparation. Twenty soccer players completed randomized sequences of pre-planned and unplanned 45°-135° CODs and their joint movements were tracked using inertial measurement units. For 90°-135° turns, the last vs. first CODs showed a more extended knee and rotated trunk at initial contact. These kinematic features may reflect insufficient time to prepare for the ground contact of a COD that immediately follows a previous COD and are more consistent with postures observed during non-contact ACL injuries. Testing COD sequences rather than isolated CODs may be more sensitive for detecting ACL injury-prone movement strategies.
