A push-off angle of 52 degrees would occur during which sprinting phase?

• A. Forward support phase
• B. Rear support phase
• C. Flight phase
• D. Recovery phase

Answer: (B)

During sprinting, propulsion happens while a foot is in contact with the ground in the stance phase, with the rear leg doing most of the pushing-off effort. A push-off angle around 52 degrees describes how the rear leg extends and presses against the ground as it drives the body forward. This occurs in the rear support portion of the stance phase, when the back foot is still planted and actively propelling, before the leg enters the flight phase. The flight phase has both feet off the ground, so no push-off angle is produced, and the recovery phase involves the leg swinging forward without pushing off.
