In Maximum Velocity, the flexed leg functions as a pendulum and thrusts forward at maximum speed, assisting which leg power?

• A. Push-off
• B. Swing
• C. Recovery
• D. Lift

Answer: (A)

In maximum velocity sprinting, the flexed leg that is not in contact with the ground moves like a pendulum, swinging forward with minimal active effort. This pendular motion positions the leg for the next ground contact and helps maintain a very high stride frequency with efficient movement. That forward swing ultimately supports the propulsion generated by the leg that is pushing off the ground during the stance phase. So, this pendulum action assists the push-off power of the other leg, which is why the best answer is the push-off. The swing, recovery, or lift terms describe different parts of the cycle and do not capture the way the pendulum-like leg mainly aids the propulsive push-off.
