The path of the center of mass of all jumping types is a PARABOLA.

The distance of the center of mass from the initial position to the floor is called the FLIGHT HEIGHT.

The greatest contributor (by percentage) to jump height is the take off height.

Force and time are the variables contributing to the impulse made by an object.

The greater the mass, the greater the momentum.

The longer the amortization phase, the greater the power produced when jumping.

The alpha motor stimulating the agonist muscle group happen during the Phase ________ of the SSC.

Hamstring's ability to control the excessive movment of the tibia during landing is decreased when landing with the knees extended.

The muscle activation during jumping is from distal to proximal.

Arm swinging during jumping add at least 10% to the total height by increasing the vertical velocity of the center of mass.

The vasti group of muscles are activated early on the jumping phase to provide a positive angular acceleration and counteracting the effect of gravity.

Angular momentum causes the body to rotate forward during the propulsion phase.

Toe landing causes greater vertical ground reaction force to the knee compared to heel landing.

What part of the GRF during jumping would you expect a sudden downward acceleration and the GRF is falling below the body weight?

Running jumpers require a 100% maximum velocity during run up.

The braking phase during running jump is due to the transition form horizontal velocity to vertical velocity.

It is important that the take off leg must have enough eccentric control to minimize excessive knee flexion during the last stride before take off.

The lower angle of attack is due to the decrease vertical impulse and a higher horizontal impulse.

The hang technique of jumping is usually recommended for skilled long jumpers.
