Abstract

The aim of the study was to assess the effect of vision and 1 or 2 cognitive tasks on lower extremity biomechanics associated with ACL loading variables (knee flexion angles, increased impact forces, and knee extension moments) during single-leg drop landing tasks. Thirty-four participants performed landing tasks with or without vision and with or without 1-2 cognitive tasks. The cognitive tasks included counting backward and/or recalling the number of beeping tones. The results indicated counting backward significantly decreased knee angles, and a lack of vision could increase impact forces. However, the combination of two cognitive tasks did not result in the greatest ACL loading variables. Further research is needed to better understand the implications of cognitive distractions on ACL injury risk during more complex athletic movements.
