Shoulder Injury Prevention Program in Swimmers
The Effect of a 6-week Shoulder Strengthening Program on Scapular Kinematics and Shoulder Strength in Division I Collegiate Swimmers
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.

Phase 2
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Prevention
Shoulder Injury
Procedure: Shoulder Strengthening
The intervention program is a 6 week shoulder and scapular stabilizer strengthening program that is performed 3 times per week. The program includes 10 exercises that are performed with Theraband rubber tubing and 2 stretches. The exercises are: shoulder flexion, Ys, Ts, Ws, IR @ 90, ER @ 90, Throwing acceleration, Throwing deceleration, dynamic hug, and low rows. The stretches include the sleeper stretch and the corner stretch.
Other Name: Shoulder injury prevention, tubing program for athletes
Experimental: 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.
