Resident Case Series: The Utility of the Athletic Shoulder Test Using Wireless Portable Force Plates for Measuring Peak Force in NCAA Division One Collegiate Quarterbacks.

PMID 40620400WHAT IT FOUND
Three NCAA Division 1 quarterbacks were tested weekly for nine weeks using the Athletic Shoulder Test.
Force plate peak force and limb symmetry were obtained, but this case series does not show that the test predicts injury or performance.
Key findings
01Three collegiate quarterbacks were tested weekly over nine weeks using the Athletic Shoulder Test.
02The dominant arm produced more mean peak force than the non-dominant arm: 142.33 N versus 128.00 N in the Y position (13% more) and 134.04 N versus 119.44 N in the T position (14% more).
03Athletes generated an average of at least 14% of body weight in force in both positions and both arms.

What it does not show
Only three quarterbacks were tested, all from one NCAA Division 1 team, so the results cannot be generalized to other athletes or competitive levels. The study lasted nine weeks and testing was not on the same day each week, which may have affected consistency. The primary aim was to explore feasibility, not to test effectiveness. The authors say validity, reliability, and normative values still need further research.
The easy way to misread this
Do not conclude that the Athletic Shoulder Test improves shoulder health or predicts injury in quarterbacks. The study is a case series of three healthy quarterbacks tested over nine weeks. It reports force values, not injury outcomes, and the authors say validity and reliability still need further research.
