Sparta doesn’t utilize countless other assessment protocols for a number of reasons, the most important being that we have not found any other tests to be reliable and valid enough to warrant further investigation. Reliable, meaning that consistent and accurate data is able to be collected across multiple populations in a simple repeatable way, and valid meaning there is a meaningful relationship to health and human movement.
In fact, for two years we tested different unilateral jumps (vertical, horizontal, and lateral) from the force plate and were disappointed to find poor intra-trial and test-retest reliability. We continue to work to identify new variables and assessments that will provide value to our partners, as well as new insights from our ever-growing database. Having said that, no additions will be made unless they meet our requirements for reliability.
