Which initiation type is the highest intensity?

• A. NCM
• B. CM
• C. DC
• D. Depth Jump

Answer: (D)

Depth Jump is the highest intensity because it maximizes the stretch-reflex and the rapid eccentric-to-concentric transition. Dropping from a height and landing sharp forces the muscles to absorb a large amount of energy in a very short ground contact time, then immediately convert it into a powerful upward propulsion. This creates high peak ground reaction forces and a quick rate of force development, demanding more neural and muscular effort than the other initiation types. The alternatives involve less pre-stretch or longer amortization, so they produce lower eccentric loading and slower transitions, yielding lower intensity.
