Several Midwest Orthopaedics at Rush physicians and researchers (Dr. Charles Bush-Joseph, Dr. Anthony Romeo, Dr. Nikhil Verma and physician in training, Peter Chalmers) recently presented their new study on pitchers and fatigue at the American Academy of Orthopaedic Surgeons. The study evaluated pitchers between ages 13-16 who had been pitching for approximately 6 years and threw an average of 94 pitches per week. Their shoulder range of motion, speed and accuracy were measured for every pitch and perceived fatigue and pain were assessed after each inning.
According to Dr. Bush-Joseph, “As expected, the boys became progressively more fatigued and painful with additional pitches. We also found that their pitching mechanics changed, which may ultimately contribute to injury.”
Dr. Verma concluded that “many young players fail to appreciate the importance of trunk, core and lower extremity strength. Early fatigue in these areas may lead to increased stress in the arm and shoulder and potentially increased risk of injury.”
