The objective of the present study was to examine the relative timing of pelvis and thorax rotations in achieving high throwing velocities in baseball pitching. During the preseason, a kinematic analysis was performed on eight pitchers. Peak angular velocities of the pelvis and thorax were determined and separation, defined as the time between the moments of maximal rotation velocity of the pelvis and thorax, was calculated. By themselves, maximal pelvis and thorax rotation velocity were not associated with throwing velocity. Separation was positively and significantly associated with throwing velocity. Results indicate that the relative timing of pelvis and thorax peak rotation velocity in pitching fastballs in baseball is a determinant of throwing velocity in skilled pitchers.

Met een goede pitcher die snel kan werpen kun je honkbalwedstrijden winnen. Maar hoe wordt een pitcher goed? Hiervoor is inzicht nodig in de ontwikkeling en het aanleren van de werptechniek van jonge talentvolle pitchers. Met dit inzicht kunnen we, met behulp van technische hulpmiddelen onze pitchers naar een hoger niveau brengen.
