COMMON MUSCULAR WEAKNESSES (4 of 6)

Infraspinatus Weakness

Increased risk of shoulder injury during shoulder transverse flexion and transverse adduction activities, particularly when elbow travels behind shoulder. Risk is compounded with a protracted shoulder girdle. During the end of a throwing movement, high deceleration forces required of the posterior cuff can cause breakdown in their tendons near their humeral attachment. Strengthening of the rear deltoid and long head of the triceps brachii can also help stabilize shoulder, although to a lesser extent as compared the infraspinatus. External rotation-muscular endurance / internal rotation-muscular endurance should be greater than 70%.

Examples of affected exercises with suggestions for high risk individuals:
o Bench Press: Bring bar lower on chest, keeping elbows closer to sides.
o Chest Press: Elevate seat so elbows are closer to sides
o Range of motion may need to be limited so elbows do not go behind shoulders

Example preventative / corrective exercises:
o Lying External Rotation
o Rows

    emoticon How would The Shoulder Press Machine fit into this? I don't think I am a "High Risk" Person but I am Curious about why I have seen very little Increase in the amount of Weight I can lift on that Machine. It doesn't 'Hurt' exactly but it is Uncomfortable enough that I don't feel safe going Higher on the Weight. I started st 10 Pounds 3 Months ago and only a few weeks ago went up to 15 Pounds (3 sets of 10 reps).
