RSI is calculated by dividing the jump height (in meters) by the ground contact time … WebThe Relative Strength Index (RSI), developed by J. Welles Wilder, is a momentum oscillator that measures the speed and change of price movements. The RSI oscillates between zero and 100. Traditionally the RSI is considered overbought when above 70 and oversold when below 30. Signals can be generated by looking for divergences and failure swings ...
WebAs mentioned in our previous article*, the reactive strength index (RSI) is a valuable testing measure to identify an athlete’s ability to produce vertical force through flight time or jump height (FT/JH) over the time spent on the floor (GCT). When using RSI as a testing measure, we can assess peak performance output from protocols such as a ...
