Question

For a standing vertical jump:

In what ways can vertical impulse be increased?

In what ways can jump height be increased?

Answer 1

i) Vertical impulse is calculated as the force produced multiplied by the duration of time over which is exerted. And relative vertical impulse is simply the vertical impulse divided by body weight. Hence, the vertical impulse can be increased by keeping feet still in contact with the ground.

ii) Jump height is determined by the relative vertical impulse, that can be produced by the lower body muscles in the upward phase of the jump, while the feet are still in contact with the ground.
