Movement pattern

Jump

The plyometric pattern of projecting the body off the ground through explosive triple extension and controlling the landing — the core expression of lower-body power.

Movement pattern

Overview

A jump is the movement pattern of driving the body off the ground and then absorbing the return to it. The take-off is a rapid, near-simultaneous extension of the hip, knee and ankle joints — often called triple extension — that accelerates the body's centre of mass fast enough to leave the floor. A countermovement dip usually precedes it, pre-stretching the leg extensors and their tendons so that stored elastic energy is released into the push-off. This coupling of a quick eccentric loading with an immediate powerful concentric drive is the stretch-shortening cycle that defines plyometric movement.

Because force has to be produced in a very short window, the jump is the archetypal expression and test of lower-body power, driven by the quadriceps, glutes, hamstrings and calves. Its landing half is equally defining: the same joints flex under control to decelerate the body and absorb ground-reaction forces. The pattern shows up in training as jump squats, jump rope, jumping jacks and the leap inside a burpee, and in sport as basketball jump shots and layups, volleyball spikes and badminton jump smashes. The same explosive triple extension is also the mechanical basis of the powerful second pull in weightlifting (the clean and snatch).

What defines it

  • Take-off is a rapid, coordinated 'triple extension' of the hip, knee and ankle joints that projects the body's centre of mass off the ground, vertically or horizontally.
  • It runs on the stretch-shortening cycle: a quick countermovement dip pre-stretches the extensor muscles and tendons, storing elastic energy that is released into the push-off.
  • It is the defining expression of lower-body power — force generated at high speed rather than under a slow, heavy load — chiefly by the quadriceps, glutes, hamstrings and calves.
  • The landing is an integral half of the pattern: the same joints flex under control to absorb ground-reaction forces through eccentric (decelerating) muscle action.
  • It appears in single-leg forms (bounds, layups) and double-leg forms (squat jumps, blocks), and the same triple-extension drive underlies explosive lifts like the clean and snatch.
