The Vertec vertical jump measuring system measures individuals vertical jump capabilities in inches. The Bertec force plate measures the ground reaction forces in newtons produced when an individual performs a jump and when they land following a jump. The Vertec vertical jump measuring system is constructed out of a steel frame and has horizontal vanes that rotate when the hand touches them. The vanes spaced half-inch between and the height of the vanes is adjustable from 6 feet to 12 feet tall. The Vertec vertical jump measuring system is considered the gold standard for measuring vertical jump height and its measurements have been found reliable.1 The Bertec force plate is a much more complicated device. It uses strain gauges to measure the force applied to the force plate. The force applied to the plate by the subject will be equal to the forces the plate applies to the subject as determined by Newton’s third law. When the strain gauge is compressed the resistance of the current running through the gauge decreases however when the strain gauge is placed under tension the resistance of the current traveling through it increases. The Bertec force plate measures forces applied to the device in the x, y and z axis using strain gauges. The strain gauges produce signals when force is applied to the force plate surface, which are…
