Abstract
An apparatus for measuring a baseball and softball pitcher'"'"'s “leg drive” for training and coaching purposes and for developing a strong leg drive. The apparatus includes a lower ground engaging plate and an upper pitcher'"'"'s foot supporting plate. The plates are slidingly secured to one another such that the upper plate is linearly moveable relative to the lower plate. A force measuring element is provided between the upper and lower plates. A pitchers rubber is secured to the upper plate. A pitcher uses the apparatus by stepping on the upper plate and pushing against the rubber while pitching, thereby linearly moving the upper plate against the element. The element thereby provides an output indicative of the pitcher'"'"'s leg drive. The element can be a load cell or a spring mechanism. An audible sound is generated when the spring force is overcome.
