Study Overview
Brief Summary
The primary purpose of this study is to assess changes in shoulder muscle strength, shoulder movement, shoulder flexibility, muscle thickness, upper arm torsion angle, and subacromial width (space where the rotator cuff muscle passes through) after completing a 6-week shoulder strengthening and stretching program in division I collegiate swimmers. The result of this study may demonstrate the effectiveness of a strengthening and stretching program to positively influence factors that have been associated with pain and injury in division I collegiate swimmers and indicate the need to implement this program for the entire team. Following a 6-week strengthening and stretching program, it is believed that scapular kinematics, shoulder flexibility, and shoulder and scapular stabilizer strength will be improved compared to control subjects.

Arms & Interventions
Shoulder Strengthening
The shoulder strengthening program is a 6-week intervention aimed to improve shoulder and scapular stabilizer strength and scapular kinematics. The program includes 10 exercises: shoulder flexion, Ys,Ts,Ws, Throwing Acceleration, Throwing Deceleration, Low Rows, Dynamic Hug, IR @ 90, and ER @ 90. The program also includes 2 stretches: sleeper stretch and corner stretch.
Intervention: Shoulder Strengthening (Procedure)
