The purpose of this study was to determine if hard and soft rib protector garments have an effect on trunk kinematics and throw performance (accuracy and speed) of experienced quarterbacks during an overhand football pass. Eight quarterbacks completed 10 throws during each of three rib protector conditions (no rib, soft, hard). Protector conditions were compared using non-inferiority testing. None of the rib protectors displayed performance or kinematics conclusively inferior to the control condition. However, the CIs of the rib protectors for two variables overlapped the noninferiority margin. In addition, among individual participants, mixed results were demonstrated. Overall, for performance and kinematics, we recommend the soft rib protector, as it did not negatively affect any throw performance variables analyzed.
