Abstract
Introduction This study determined anterior cruciate ligament (ACL) force and its contributors during a standardized drop-land-lateral jump task using a validated computational model. Methods Three-dimensional whole-body kinematics, ground reaction forces, and muscle activation patterns from eight knee-spanning muscles were collected during dynamic tasks performed by healthy recreationally active females (n = 24). These data were used in a combined neuromusculoskeletal and ACL force model to determine lower limb muscle and ACL forces. Results Peak ACL force (2.3 ± 0.5 bodyweight) was observed at 14% of stance during the drop-land-lateral jump. The ACL force was primarily generated through th..
