As the rear foot lifts up and swings forward, the opposite arm swings in which directions?

• A. Forward, Up
• B. Backward, Down
• C. Up, Forward
• D. Forward, Backward

Answer: (A)

In sprinting, the body moves as a coordinated system where arm and leg work opposite to help propel you forward and maintain balance. When the rear foot lifts and swings forward, the opposite arm naturally moves forward and upward. The forward part of the arm drive helps push the torso forward, while the upward motion helps keep the elbow high and the hand in a compact path, which stabilizes the torso and reduces rotational energy. Moving the arm backward or downward would oppose the forward momentum and disrupt balance, so the forward and upward swing is the most efficient pattern for this phase of the stride.
