| Basketball reaction time task Prior to utilizing the force plate during each data collection it was zeroed. Participants stood in a crouched triple threat basketball position on top of the Bertec 4060 NC force plate. Two strips of duct tape were placed on top of the force plate to mark foot placement for all participants for standardization. The participants were instructed to place their feet just lateral to the two strips of duct tape and hold a basketball in their hands. A computer screen displayed a timed PowerPoint to the participants, which instructed them to cut to their immediate left off of the force plate as quickly as possible. The jump left command appeared after 5 seconds. The VICON software was synchronized to begin recording at the same time as the PowerPoint display began. Participants were all asked to perform one practice cutting maneuver prior to being recorded. A small gray box was taped to the left of the force plate as a target for participants to aim for with their lead outside foot. Researchers chose to have participants only cut left for standardization. The time to get both feet off the force plate was recorded. This was determined by the force plate reaching 0 Newtons of force relative to time. Force plate data was recorded at 1,000 Hz. | — |

| Football hip proprioception task Participants stood with their right upper extremity extended to the front at shoulder level simulating a blocking maneuver, while holding a football just above their left hip. The right lower limb was extended forward in line with the right shoulder while the left lower limb was extended to the back in line with the left shoulder. Participants were asked to place their heels at the base of tape marks on the ground before starting the activity. Silver 19mm MoCap reflective markers were placed on their right and left anterior superior iliac spine using surgical tape. The Vicon MX camera motion analysis system consisted of 8 infrared Bonita 0.3 megapixel cameras and was calibrated daily as suggested by the manufacturer. Kinematic data were recorded at 100 Hz using Nexus 1.7.1 software. After participants assumed the starting position the motion recording was begun. Within approximately two seconds participants were verbally commanded to turn their hips 90 degrees to the left along with the rest of their body and then freeze. At baseline, mathematically a line was formed between their ASIS. After turning to the left and freezing a second line was established between their ASIS at the new position and the angle between the two lines was calculated. The ability of the participant to accurately reach 90 degrees was used as a measure of participant core proprioception capability. | — |
