Purpose: Dozens of variables can be derived from the countermovement jump (CMJ). However, this does not guarantee an increase in useful information because many of the variables are highly correlated. Furthermore, practitioners should seek to find the simplest solution to performance testing and reporting challenges. The purpose of this investigat...

Previously it has been reported that eccentric muscle actions result in higher force production (20-60%) compared to concentric muscle actions (1, 2). This may be the result of both mechanical (2, 3) and neural differences (4-6) between the two actions. As a consequence of athletes being stronger eccentrically, traditional strength testing may not...
