A method for using inertial measurement units in to identify pitching events in baseball

This study investigated a method to use inertial measurement units (IMUs) in certain types of baseball biomechanics research. The method calculates the timing of maximum knee height (MKH) and ball release (BR) using gyroscopic data and defines them as the starting and ending points of the pitching motion. The new method had some significant differences in determining the exact timing of MKH and BR. However, the temporal differences between the two methods was very small, 0.0435s and 0.087s, making the method practically viable for some baseball biomechanics studies.
