What common overuse injury occurs in swimmers due to tendon overload?

1. Bicipital tendonitis

2. Rotator cuff tear

3. Shoulder impingement

4. Subacromial bursitis

The correct answer is: Bicipital tendonitis

Bicipital tendonitis is indeed a common overuse injury among swimmers that occurs due to tendon overload. In swimming, repeated overhead movements can lead to wear and tear on the biceps tendon, especially where it attaches to the shoulder joint. The mechanics of swimming involve extensive use of the shoulder, particularly in strokes like freestyle and butterfly, which can place excessive strain on the biceps tendon. This condition can lead to inflammation and pain, particularly felt in the front of the shoulder. The repetitive nature of swimming contributes to this overload, with the biceps tendon becoming more susceptible to injury. Swimmers may report pain during their swimming sessions, especially when lifting their arms overhead or during activities involving shoulder flexion. Other options listed, such as rotator cuff tears, shoulder impingement, and subacromial bursitis, can also occur in swimmers but are less specifically associated with the overload and inflammatory processes linked to the biceps tendon. These injuries may result from similar biomechanics but usually involve different mechanisms of injury or patterns of strain within the shoulder complex. Understanding the specific role of the biceps tendon in swimmer's shoulder helps clarify why bicipital tendonitis is a key concern in this sport.
