During Maximum Velocity, leg drive is facilitated by which action?

During Maximum Velocity, leg drive is facilitated by which action?

• A. Explosive arm action
• B. Gentle arm action
• C. No arm action
• D. Relaxed arm action

Answer: (A)

Explosive arm action drives the whole sprinting rhythm at maximum velocity. When the arms move rapidly and forcefully, they create forward momentum and help stabilize the torso, which enables the hips to extend more powerfully and the legs to cycle faster. This coordinated upper-body drive boosts stride frequency and helps maintain a forward lean without breaking form, producing greater leg drive overall. Gentle or relaxed arm action wouldn’t provide the needed momentum or coordination, and no arm action eliminates the upper-body contribution that helps set the pace for the legs. A completely still or overly relaxed arm swing also disrupts balance and rhythm, reducing hip extension and cadence. So the explosive arm action best supports the high-speed, powerful leg drive required at maximum velocity.
