| Shoulder external rotation strength, kg c | 0.986 [0.977-0.992] | Yes |
| Grip strength, kg | 0.939 [0.898-0.964] | Yes |
| Plank time, seconds d | 0.487 [0.141-0.693] | No |

All ROM variables were active ROM. CI, confidence interval; ICC, intraclass correlation coefficient; ROM, range of motion.
Data collected with the shoulder at 30° of abduction, 30° of flexion, and neutral rotation.
Data collected with the shoulder in full adduction, neutral flexion/extension, and neutral rotation.
Players were asked to assume a plank position and a timer was set to determine time between when the player assumed the position and when the player was no longer able to maintain their body as a flat plane.
Players were asked to stand on their right foot, touch their right hallux with their left index finger, and vice versa. If the player was unable to complete both sides without a Trendelenburg shift of the hips, the test was considered normal.
