This study was carried out to suggest the basis of training method for the prevention of injury by analyzing the Biomechanical of release along the increase of pitch of a baseball pitcher and the change of Ulnar Collateral Ligament. To achieve this purpose, two starting pitchers belonged to S university was instructed to implement the exercise pitches more than 10 times and pitch 15 balls for each inning for 7 innings, total 105 balls. The condition before pitching and the last pitching actions were selected out of each inning from the 4th inning when the number of pitch exceeds 50 for collecting of data and the ground reactions and ultrasound(Accuvix V10, Korea) were measure, and pitch fast balls whose ball speed was above 130km during the initial time. It was shot by 5 units of infrared camera(MotionMaster 200, visol, Korea) at 200 f/s and measured by 2 units of measuring equipment of ground reaction(AMTI ORG-6, MA) at sampling speed of 2000 Hz/s through Kwon 3D XP(visol, Korea). As a result, negative change of UCL was observed when the number of pitches increased, and change of UCL increased with higher shoulder angular velocity. When the change of maximum vertical reaction increased, change of UCL decreased. In conclusion, to prevent UCL, pitches must be performed by using the lower body. Future research will need to secure more subjects to ensure reliability and include variables like change of lower body angle and upper body rotation angle that influences ball velocity.
