Absolute Speed Flight Transition describes the harmony where which limbs move in which directions?

• A. Front leg moves down and back; back leg moves up and forward
• B. Front leg moves up; back leg moves down
• C. Both legs move down
• D. Front leg stays still while back leg moves forward

Answer: (A)

The situation tests how limbs coordinate to generate propulsion during a rapid speed transition. The best pattern has the front limb contacting the ground and pushing downward and backward, which helps drive the body forward as the foot plants and the body passes over it. At the same moment, the hind limb moves upward and forward, preparing for its next contact and helping reset the leg for another powerful push. This combination creates a smooth, continuous propulsion cycle where one limb provides the thrust while the other repositions, maintaining balance and momentum during the transition to high speed.

Other patterns either waste propulsion potential, disrupt timing, or fail to provide the necessary push-off and reset sequence—for example, moving one limb without contributing to a backward push, or having both limbs move in such a way that forward thrust is reduced.
