In this study we used musculoskeletal modelling with mathematical optimization tools to find whole-body kinematics that simultaneously reduce risk of injury and enhance sports performance. Combining these objectives has long been the goal of sports science research. We focused on improving hang-time parameters in volleyball (Gupta et al., 2015). We were able to preserve an advantage of hang-time (late swing) and address its disadvantage (potential loss in peak height of the hitting arm) by increasing the height of the hitting wrist by 1 cm, while at the same time not increasing the shoulder moments. This study provided a proof of concept that this optimization framework can potentially find a balance between performance and injury prevention in a complex sports task.
