Dual-task and anticipation impact lower limb biomechanics during a single-leg cut with body borne load

摘要

Abstract This study quantified how a dual cognitive task impacts lower limb biomechanics during anticipated and unanticipated single-leg cuts with body borne load. Twenty-four males performed anticipated and unanticipated cuts with and without a dual cognitive task with three load conditions: no load (～6?kg), medium load (15% of BW), and heavy load (30% of BW). Lower limb biomechanics were submitted to a repeated measures linear mixed model to test the main and interaction effects of load, anticipation, and dual task. With body borne load, participants increased peak stance (PS) hip flexion (p?=?.004) and hip internal rotation (p?=?.001) angle, and PS hip flexion (p?=?.001) and internal rotation (p?=?.018), and knee flexion (p?=?.016) and abduction (p?=?.001) moments. With the dual task, participants decreased PS knee flexion angle (p?
