Conflicting methodologies are used to define certain countermovement vertical jump (CMVJ) phases, which limits the identification of performance-enhancing factors … WebDifferent Jump Phases. Using velocity, we are able to break jumps down into different phases. These phases are descriptive of how an athlete's velocity changes during the movement, and are often also indicative of what kind of muscle action they are enduring. Phases of a Countermovement Jump.
