Abstract

To examine the effects of breast support on trunk and knee joint biomechanics in female collegiate athletes during a double-limb landing task.Methods: Fourteen female athletes completed five landings in three different sports bra conditions: no support, low support, and high support. 3D kinematics and ground reaction forces were recorded simultaneously. Visual 3D was used to calculate trunk and knee joint angles and moments. Custom software determined discrete trunk and knee joint variables. A repeated measures analysis of covariance with post-hoc t-tests compared landing biomechanics by condition.Results: Greater breast support was associated with reducation in knee flexion and knee valgus angles as well as increases in knee varus moments. Greater breast support was associated with greater trunk flexion angles at initial contact and greater peak trunk flexion angles.Conclusions: Lower levels of breast support are associated with knee joint and trunk biomechanical profiles suggested to increase ACL injury risk.
