Arm injuries are commonplace among Major League Baseball pitchers, and such impairments may have cost a few notable pitchers, such as Randy Johnson and Brandon Webb, a chance to play in the 76th All-Star Game tonight.
A pitcher’s shoulder joint can rotate as quickly as 7,000 degrees per second—nearly 20 complete revolutions in one second if the shoulder could rotate completely freely—during a pitch, making it one of the fastest movements possible by the body, and this repetitive motion of the arm contributes to the fatigue-related injuries. Ian Byram and his colleagues at Vanderbilt Medical Center are hoping to reduce the damage by identifying pitchers at risk for injury during the preseason, allowing teams to design unique strength training routines for susceptible athletes.
