During sprint start, the hand moves toward the forehead to enhance momentum and overcome inertia. The correct directional description is:

• A. Toward the forehead
• B. Toward the hip
• C. Toward the chin
• D. Toward the shoulder

Answer: (A)

During sprint starts, turning leg power into forward speed depends on how you move the arms to help drive the body forward. The hand moving toward the forehead describes the common drive path of the arm during the initial acceleration: the elbow drives back and the hand travels forward and upward toward the face. This path helps align the force you generate with the direction you want to move, helping pull the torso forward and keep the trunk stable as you accelerate. In short, this arm action creates a forward component of force that contributes to momentum and helps you overcome inertia. If the hand were moving toward the hip, chin, or shoulder, the force path would be less aligned with forward propulsion and could disrupt posture or waste energy instead of adding to horizontal acceleration. Focusing the hand toward the forehead keeps the drive compact, efficient, and oriented to move you straight out of the block.
