(THREAD): Force, ground contact and speed/COD
Why I think the idea of “absorbing,” force doesn’t explain the whole picture
Contacts are based on collisions
Collisions can conserve energy OR energy AND momentum
This is a key in distinguishing what occurs

Depth Jumps (top) vs. Drop Jumps (bottom)
Which of these conserves momentum as well as energy? The one that efficiently progresses movement in a more effective manner via shorter ground contact
We encounter eccentric forces and then produce output (amortization phase)

SPRINTING (energy AND momentum is conserved)
Ability to accept forces produces the ability for high levels of stiffness
Stiffness describes the change in flexion in our limb pre and post contact
Elite sprinting is defined by limbs that can change minimally AND produce power

Essentially, I feel that absorbing is more descriptive of contacts where deceleration is the only goal
Otherwise, this only details one part of the amortization phase of power output and ground contact
