Abstract: An apparatus for measuring a ball hitter's “leg drive” for training and coaching purposes and for developing a strong leg drive (ground force). The apparatus includes a ground engaging lower plate and an upper plate that supports the hitter's foot. 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. The apparatus is used by the hitter stepping on the upper plate and pushing while hitting, thereby linearly moving the upper plate against the lower plate and the force measuring element, which may comprise a load cell or a spring mechanism. The apparatus provides an output indicative of the hitter's leg drive (ground force) level. In some embodiments, an audible sound is generated when a preselected leg drive level is reached.

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.
