s commonly seen in athletes who sustain an increase in training load, and is most often due to overuse. Tendons respond poorly to overuse, therefore healing is slow. This can leave a tendon pathologically defective, which decreases tendon strength and leaves it less able to tolerate load, thus vulnerable to further injury[1] or tendinosis. Extrinsic factors contributing to this condition include training errors and inappropriate footwear. Intrinsic factors include inflexibility, weakness and malalignment. [3]
