In Maximum Velocity Early support with continued concentric hip extension, which effect is achieved?

• A. Minimizes braking effect or foot strike
• B. Increases braking effect
• C. Delays foot contact
• D. Increases vertical displacement

Answer: (A)

During Maximum Velocity, keeping the hip in concentric extension as the foot contacts the ground helps drive the body forward rather than stopping it. When the hip continues to extend, the leg is actively propelling the body and the foot tends to land under the center of mass, producing less backward ground reaction force. That means less braking at contact and a smoother, faster step cycle. If braking were to increase, the foot would strike ahead of the center of mass and a larger backward force would slow you down. Delaying foot contact would disrupt the rapid, under-body contact pattern that supports high velocity, and increasing vertical displacement would waste energy moving upward rather than forward.
