Abstract

This study assessed novel zero-impact perceptual (ZIP) training, in which there is cognitive but no physical workload, in reducing biomechanical risk factors associated with anterior cruciate ligament injury. Tri-planar knee moments in amateur Australian rules footballers (n=16) were calculated during evasive sidestepping of 3D-projected opponents in 1-on-1, 2-on-2 and 3-on-3 game-based situations, pre and post intervention training. Video-only (VO) and Cueing (Q) training groups verbally evaded opponents in 8 sessions over 4 weeks. Cueing incorporated an additional task of counting visual cues within the scene. Training groups showed reductions in peak valgus and internal rotation moments, with greater reductions observed in Q training relative to controls. Results suggest that ZIP training can reduce ACL injury risk without impacting physical workload.
