However, alterations in lower-limb kinematics and kinetics during rotational landings, and sex-specific responses, are currently largely unexplored. This study, therefore, explored the differences in lower-limb kinematic and kinetic characteristics between rotational and straight landings, and the sex-specific responses to rotational landings. Thirty-six healthy team-sport athletes (eighteen males and eighteen females) performed straight bilateral and unilateral landings, and rotational (clockwise and counterclockwise) landings, from a box while lower-limb kinematics and ground reaction forces (GRFs) were recorded. Rotational landings were found to emphasise (p < 0.001) hip flexion angles at initial contact and peak vertical GRF. Differences between males and females (p < 0.001) were identified during rotational landings (but not straight landings) for peak ankle dorsiflexion and time to peak vertical GRF, with significant task-sex interactions. Compared to the bilateral landing, unilateral tasks affected the magnitude or highlighted sex-specific differences for nine and one biomechanical characteristics, respectively. Together, these outcomes provide further insights into lower-limb kinematic and kinetic responses to rotational landings. These findings offer additional support for the use of rotational, as well as unilateral elements, for ACL-injury risk screening practice.MedicineHealth ProfessionsArticleSCOPUS10.5114/jhk/2007652-s2.0-10502982506118997562
