Across every performance measure, including maximal voluntary isometric contraction,
countermovement jump height, 20 m sprint time, knee extensors, 5 -0-5 agility, the Montmorency group showed better performance than the placebo group.

Exploring the effects of a 6 - week period of weightlifting derivative training on vertical
jump height, Otto et al. (2012) found that
countermovement vertical
jump height was improved as a result of the training, although the improvements were similar to those produced by kettlebell training.
If you imagine you have a vertical
jump of 80 centimeters and you perform a simple
countermovement jump, you
jump 80 centimeters up and land from 80 centimeters
height, which results in an impact from a
height of 80 centimeters.
The increase in
height and the percentage fat and muscular masses of the subjects were also recorded, as was their ability to
jump (
countermovement jump [CMJ]-RRB-, their leg strength and power (squat test), and their leg anaerobic power (continuous
jump test [CMJ15 ″]-RRB-.
Although many different biomechanical factors increased with
jump training, it was the increase in hip flexion angle (which leads to a longer
countermovement phase, a longer duration concentric phase, and more concentric work done) and an increase in hip joint work done that were most important for driving the gains in
jump height, at least on a joint level.
