Summary
Competitive swimmers frequently experience shoulder pain due to high training volumes. Supraspinatus tendinopathy is the most common cause, highlighting the need for comprehensive injury evaluation.
Area of Science:
- Sports Medicine
- Orthopedics
- Biomechanics
Background:
- Competitive swimming involves high weekly yardage and shoulder rotations, leading to significant stress.
- Shoulder pain is the most prevalent musculoskeletal complaint among competitive swimmers.
- Over 250,000 swimmers are registered with USA Swimming, indicating the sport's popularity.
Purpose of the Study:
- To review the literature on shoulder injuries in competitive swimmers.
- To identify common causes and potential treatment strategies for swimmer's shoulder.
Main Methods:
- Literature search of Medline, Google Scholar, and review articles.
- Data collection from 1980 through January 2010.
Main Results:
- Supraspinatus tendinopathy is the most frequent cause of shoulder pain in swimmers.
- Glenohumeral instability and labral tears are reported, but data on prevalence and treatment are limited.
- High stroke repetitions and upper extremity forces make the shoulder vulnerable.
Conclusions:
- The shoulder is uniquely susceptible to injury in competitive swimmers due to repetitive motions.
- A thorough evaluation should encompass the entire kinetic chain, including trunk strength and core stability.
- Further research is needed on the prevalence and treatment of glenohumeral instability and labral tears in swimmers.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
