What does Reactive strength Index indicate?

The reactive strength index is a measure of reactive jump capacity and displays how an athlete copes with and performs plyometric activities. Jump height and flight time can both be used to measure RSI. The ground contact time of the RSI test is an important parameter for test selection and when interpreting results.

What is a good reactive strength index?

With this approach, an RSI in the drop jump greater than 2.5 can be considered excellent whereas an RSI below 1.5 identifies athletes requiring better reactive strength. Athletes with a low RSI require progressions and a gradual increase in load when it comes to plyometric training.

What does just jump mat measure?

The Just Jump testing system is a contact mat that collects air and contact times. Most coaches that use the testing device measure air time when testing vertical jumps. You can also use the equipment for sprint and shuttle tests, but for most coaches, it’s a handy tool for estimating vertical jumps.

What is a good RSI mod score?

RSImod values ranged from 0

How is reactive strength measured in a jump?

Researchers have traditionally assessed reactive strength during a drop jump where an athlete drops from a set height and upon landing performs a vertical jump at maximal effort. This test yields a measure of reactive strength known as the reactive strength index (RSI).

How is the reactive strength index ( RSI ) calculated?

The Reactive Strength Index (RSI) measures muscle­tendon stress and their reactive jump capacity, important for athletes in sports requiring dynamic jumping activities. RSI is calculated by dividing the jump height by the ground contact time.

Why do you need a jump mat for training?

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).

Is the RSI a valid measure of reactive jump capacity?

The RSI has been proven to be a valid and reliable measure of reactive jump capacity, though it is important to understand that there is no “gold-standard” test for the RSI to be compared too. Nonetheless, the following tests have been proven to be valid and reliable measures of RSI:
