What is Swimmer’s Shoulder?



Swimming is one of the few, if not only, sports that utilizes the upper body and shoulders to move the entire body forward. Swimmers, both male and female, tend to be very flexible and have more range of motion in their shoulders than the average athlete. Swimming is also unique because the water gives resistance that the air does not. The reliance on the upper body, coupled with the resistance of the water and repetitive use of the shoulder can lead to a spectrum of overuse injures termed “swimmer’s shoulder”. 



Swimmer’s shoulder rarely results in permanent injury requiring surgical intervention. The most common swimmer’s injury found on MRIs of the shoulder is tendonitis. Tears of the rotator cuff or labrum are much less common. 


Anatomy

In order to better understand swimmer’s shoulder, we need to review the anatomy of the shoulder. The key muscle group of the shoulder is the rotator cuff, which consists of the subscapularis, supraspinatus, infraspinatus, and teres minor. The primary role of the rotator cuff is to function as the dynamic and functional stabilizer of the glenohumeral joint.

The muscles and the attached tendons of the rotator cuff can be overused and injured in shoulder dominant activities such as swimming. The most commonly injured portion of the cuff is the supraspinatus. On the other hand, the "power muscles" of the shoulders, including the latissimus dorsi, pectoralis, and deltoid, are responsible for moving the arm through space or water, but rarely sustain significant injury.

Treatment

Treatment protocol for swimmer’s shoulder is as follows:

  • Oral anti-inflammatories to decrease inflammation of the shoulder
  • Strength training of the shoulder and rotator cuff
  • Maintaining range of motion in the shoulder

The above is normally achieved with physical therapy or a physician directed home exercise program. It is important to consult a physician before adopting a treatment plan. Without guidance, one can potentially make the injury worse. 


Prevention

Swimmer’s shoulder may be avoided with a regimented dry land program in the off-season. Training programs should focus on strength training and flexibility of the rotator cuff and other shoulder blade muscles.
