The reactive strength index (RSI), is the primary outcome parameter of the Drop Jump (Fig-1, top left) and is an indicator for an athlete’s reactive strength capabilities. The RSI is made up of the rebound jump height (Fig-1, bottom left) and the ground contact time. High RSI values result from a high jump height and a short ground contact time.
Besides these key metrics, there are other qualitative and quantitative parameters available for each ReGo test. For example, the force-time curve (Fig-1, right) is displayed separately for the left and right foot as well as for total force.Â
