ForceDecks Tests: Athletic Shoulder (ASH) Test Protocol

The Athletic Shoulder (ASH) Test  (Ashworth, Hogben, Singh, Tulloch, Cohen, 2018) is a novel test used to monitor upper body performance, neuromuscular fatigue and readiness, and more specifically an athlete’s ability to transfer force across the shoulder girdle.  The ASH Test was developed by Ben Ashworth (you can follow Ben on Twitter and Instagram).  

The ASH Test evaluates shoulder strength in three different positions (" I", "Y" and "T"), each from the prone lying position:

I
POSITION
(arm extended above head)
Y
POSITION  
(arm extended at a 45° angle)
T
POSITION  
(arm extended to the side)
