There is no question studies have shown an injury dilemma exists within youth baseball pitchers. A unique approach to solving this problem focuses on pitch efficiency. Studying the efficiency of a pitcher allows researchers to investigate loads placed on a joint per mile per hour of ball velocity based on the height and weight of a subject. Knowing how loads on the upper arm behave according to ball velocity leads researchers to a secondary, but central question, of how the lower extremities affect loads placed on upper extremities.A comprehensive investigation of the drive leg has shown its value in relation to upper body kinetics and ball velocity. Although energy flow analysis of the drive leg is known to be essential in optimizing pitching mechanics, the stride leg should not be ignored. This document addresses the lack of energy analysis on the stride leg of an adolescent baseball pitcher within baseball biomechanics literature. In completing a thorough energy transfer analysis and joint energy production on the stride leg, a genuine evaluation can be made with regards to how the drive leg and stride leg interact with one another and how this affects a pitcher's kinematic movement and ball velocity. The evaluation, however, cannot only include energy analysis. Understanding energy flow is only relevant if youth coaches can apply what is learned here to address improper mechanics performed by their athletes to limit injury frequency. Taking results from energy flow and quantifying how they relate to visual cues allows this; therefore, this study measures how the most important stride leg energy flow metrics, as they relate to upper extremity joint efficiencies, are affected by kinematics that can be visually observed. By focusing solely on the stride leg, this study provides necessary insight as to the importance of the stride leg in mitigating effects due to injury while enabling adolescent athletes to consistently perform at competitive levels.
