This Jump mat is the only device that calculates muscle power tests, such as Reactive Strength Index (RSI). A jump mat is an excellent tool in many or continuous jump protocols in training. With no feedback, it’s hard to keep the level of effort high or to know when to stop. The jump mat provides immediate feedback which helps with motivation. What’s special about this Jump Mat? This mat can measure Reactive Strength Index (RSI). The Reactive Strength is a ratio of Jump Height to Contact Time shown when performing rebound jumps. Jump Height can be measured to 1/1000th second making this extremely accurate. The jump mat uses this to calculate the height jumped in 0.1cm intervals. Flight Time, this is the time between leaving and landing on the mat measured to 1/1000th second. Contact Time is when the athlete steps on the mat and immediately jumps into the air, landing back on the mat. The contact time on the mat is tracked to a 1/1000th second. The energy this is measured in Joules The Power is Measured in kW Take off Velocity is Measured in m/s Windows software only ?- not compatible with Mac Measurement methods Vertical Jump Mode – Being on the mat for more than one second assumes a standing jump, results show height jumped and flight time Rebound Jump Mode – This is when an athlete steps onto the mat and jumps into the air straight away On landing, Contact Time and Flight Time are then measured. Height Jumped and Reactive Strength also show.
