Background: Baseball players who have shoulder pain due to throwing have reduced shoulder joint range of motion and shoulder external rotation muscle strength, which are also recognized as general features of baseball players. The purpose of this study was to examine whether these factors affect the development of shoulder pain through prospective studies.
Methods: In members of high school baseball teams, shoulder joint function was evaluated by field position. during the off-season and observations were collected over a 2-month period during the season. Subsequently, evaluation items that affected the occurrence of shoulder pain were analyzed.
Result: Twenty-four out of the 84 participants developed shoulder pain, and multiple logistic regression analysis extracted the shoulder rotator strength ratio and field position as significant variables.
Consideration: A decrease in the shoulder rotator strength ratio significantly affected the occurrence of shoulder pain in all field positions. Although stretching has been reported to be important for preventing throwing disorders, attention must also be paid to muscle strengthening exercises that take into account the balance of rotator muscle strength.
