About this episode
This episode explores the differences in pitching biomechanics and performance between the windup and stretch positions in baseball, based on a research study.
In baseball, pitchers have two ways they can deliver the ball. They can either go out of the stretch position or the windup. Deciding which delivery to use may be personal preference, but it can also be dictated by game situations. The question becomes, are there benefits to using one method over the other? In this episode, we dive into the topic by way of a research study published in the Human Kinetics Journals and the Journal of Applied Biomechanics. Listen along and learn what the research says.
