What is the common overuse injury experienced by swimmers due to tendon overload?

Bicipital tendonitis is the correct answer because it specifically involves inflammation of the biceps tendon, which is commonly associated with repetitive overhead activities, such as those performed in swimming. Swimmers frequently perform strokes that require extended arm motions, putting significant stress on the shoulder and the biceps tendon. Over time, this leads to tendon overload, which can result in irritation and inflammation, manifesting as pain in the front of the shoulder.

In contrast, while a rotator cuff tear can occur in swimmers, it typically involves a more significant injury mechanism and is not as directly linked to the repetitive nature of swimming as bicipital tendonitis. Sub-acromial bursitis can also result from repetitive shoulder use but is more about inflammation of the bursa rather than the tendon itself. Frozen shoulder, or adhesive capsulitis, is characterized by stiffness and pain in the shoulder joint, which can occur for various reasons but is not specifically an overuse injury related to swimming.
