Answer

Bicipital tendinitis frequently occurs from overuse syndromes of the shoulder, [7] which are fairly common in overhead athletes such as baseball pitchers, swimmers, gymnasts, racquet sport enthusiasts (eg, tennis players), and rowing/kayak athletes. [8, 9, 10, 11] Trauma may occur because of direct injury to the biceps tendon when the arm is passed into excessive abduction and external rotation. This pattern of shoulder injury can also occur in the left shoulder of right-handed golfers. Many overuse injuries coexist with some degree of bicipital tendinitis and rotator cuff tendinitis.

The athletic shoulder differs qualitatively from the biomechanics of the shoulder in daily life because of the higher energies and repetitive motions that are involved in athletic activities. Sports activities that require repetitive overhead motion with inadequate reparative time may cause the biceps tendon to break down.
