A new study:

Study 20Title

suggests a threshold for career innings pitched and rotator cuff injury in MLB pitchers:

800 20inning 20threshold


and points to the eccentric (lengthening) contraction of the rotator cuff during the "Follow Through" to be a significant cause of shoulder injury:

Are You Doing Your Eccentric Training to Help Prevent Injury?

Using a 2-pound medicine ball, practice the 2-knee drill:

2 knee 20drill

In a 3-repetition set:

    • Hold on to the medicine ball for the 1st and 2nd repetition
      • This strengthens the rotator cuff during the eccentric contraction of the "Follow Through"
    • Throw the medicine ball into a wall for the 3rd repetition
