In Ultimate and other disc sports, the forehand "flick" throw is one of the most common movements. Like a forehand in tennis, the movement starts with the arm to the side and slightly behind the player. The arm is then whipped foreward in the horizontal plane.
I've anecdotally seen a number of shoulder and elbow injuries that seem to be caused by this movement. A player throws hard and throws often and finds that the movement produces pain.
I'm not particularly interested in specific diagnoses and treatments. What I'd like to know is how we can prevent injury by using prehab exercises that strengthen and mobilize the arm for the forehand disc throw.
I know that getting the arm stronger and more mobile in general will help, but what are the specific needs of this movement?
