Pre- and postseason measurements of peak torque arm strength were made at 180 deg./sec. and 300 deg./sec. on both throwing and nonthrowing arms of five male high school varsity baseball pitchers. The major findings were significant losses in adduction strength in both throwing and nonthrowing shoulders at 180 deg./sec. and internal rotation strength for both sides at both speeds. The primary implication from these preliminary findings is that significant losses of arm-shoulder strength may be associated with injuries to the pitching arm.
