WebJan 1, 2024 · Male professional rugby league players (n = 21, age = 20.8 ± 2.3 years, height = 1.82 ± 0.06 m and body mass = 94.3 ± 8.4 kg) performed 3 DJs (30 cm) and CMJs on a force plate. Reactive strength index and RSImod were subsequently calculated by dividing jump height (JH) by ground contact time (GCT) and time to take-off (TTT), respectively. WebThe RSI was developed at the Australian Institute of Sport and is assessed in a drop jump by dividing jump height (m or cm) by ground contact time (s or ms) thereby providing a tool that measures...
