Explosive specific force trough small sided games and few players?: part 3.

After seeing the relationship between the acceleration and deceleration phases of a near maximum sprint with hard change of direction (180º), and how it affects to the metabolic power (Di Prampero approach) and mechanic power (Bezodis approach), now is time to go one step forward.
In order to try to clarify this relationship between acceleration and deceleration phases of similar actions, I propose you this simple analysis in which we compare the impulse phase (acceleration) of a typical squat jump (just body weight, without extra load) with the braking phase (deceleration) of a traditional drop jump from 40 cm, as Verkhoshansky originally proposed it (fall down from a height and stop the movement as fast as possible, with no jump after). Both jumps has been performed by the same soccer player with maximum intensity (trying to jump as high as possible in an explosive movement, and to brake as fast as possible the falling down).
The intention is to try to show the typical characteristics of the relationship between maximal acceleration and maximal deceleration in a simple movement.

Enjoy, and stay tuned!!!
