The reactive strength index measures the reactive jump capacity of the athletes and is obtained be completing a drop jump. The athlete must first start at ground level and step-up onto a block or box prior to stepping off and immediately rebounding back off the floor, with the intent to jump as quickly and high as possible. what is reactive strength index RSI is one component of the Strength Qualities Assessment Test (SQAT) created by the Australian Institute of Sport. The SQAT assesses the strength capabilities of the leg extensor muscles and is intended to specifically gauge the progression of running and jumping movements (7). The complete guide to the Reactive Strength Index December 12, 2019 / in Warren Young / by Warren Young In my earlier posts, I have discussed reactive strength (RS) and the use of plyometric training for developing speed and jumping performance . Purpose: To assess the relationships between reactive strength measures and associated kinematic and kinetic performance variables achieved during drop jumps. A secondary aim was to highlight issues with the use of reactive strength measures as performance indicators. Methods: Twenty-eight national- and international-level sprinters, 14 men and 14 women, participated in this cross-sectional Reactive strength is an indirect measure of the neuromusculoskeletal system and the athlete’s ability to efficiently accept and reverse energy into dynamic movement. It is highly dependent on the neural capacity of the athlete, and also their mechanical capacity. Reactive strength may be one of the most powerful indicators of athleticism, as it represents the ability to effectively make use the stretch shortening cycle (SSC). It is an expression of the ability to change from an eccentric to a concentric contraction as quickly as possible and with as much force as possible. The reactive strength index (RSI) is a measure of force and the time that is taken to develop it, by calculating the jump height divided by ground contact time during the depth jump (DJ) . The RSI is typically determined using a force platform or contact mat .
