Effect of a 6-Week Weighted Baseball Throwing Program on PitchVelocity Pitching Arm Biomechanics Passive Range of Motion and InjuryRates

摘要

Background:Emphasis on enhancing baseball pitch velocity has become popular, especially through weighted-ball throwing. However, little is known about the physical effects or safety of these programs. The purpose of this study was to examine the effects of training with weighted baseballs on pitch velocity, passive range of motion (PROM), muscle strength, elbow torque, and injury rates.
