This study was conducted to establish whether or not a correlation exists between peak torque production of upper extremity (UE) musculature and throwing speed. Eleven professional baseball players were tested for upper extremity peak torque production using a Cybex II Isokinetic Dynamometer. Throwing speed was meas ured with a radar gun. Results of statistical analysis performed on the data indicate a correlation between shoulder adductors and throwing speed.
