Swimming (sport) less stress on joints. Due to continuous rotation and usage, the shoulder (rotator cuff) is the joint most susceptible to injury in swimmers. As opposed to a single incident, injury to the rotator cuff in swimmers is a result of repeated trauma and overuse. The joint is most prone to injury when the arm is repetitively used in a position above the horizontal. This position occurs in each of the four swimming strokes in every cycle of the arms. Of the four muscles and tendons of the rotator cuff, the injury, or tear, is most likely to occur in the
Mucous sheaths of the tendons around the ankle the level of the tip of the malleolus, while that for the Flexor digitorum longus is slightly higher; the former is continued to the base of the first metatarsal, but the latter stops opposite the first cuneiform bone. On the lateral (outer) side of the ankle a sheath which is single for the greater part of its extent encloses the Peronæi longus and brevis. It extends upward for about 4 cm. above the tip of the malleolus and downward and forward for about the same distance. Mucous sheaths of the tendons around the ankle The mucous sheaths of the tendons
