Why don’t you report on other metrics like peak force?

Sparta doesn’t display countless other variables (like peak force) for a number of reasons, the most important being that we have not found any other variables to be reliable and valid enough to warrant further investigation. 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.
