What sprint training goal is emphasized to achieve a rapid stride rate?

• A. Brief ground support times to achieve a rapid stride rate
• B. Prolonged ground support times to increase strength
• C. Increase vertical impulse during ground contact
• D. Increase stride length without changing contact time

Answer: (A)

Rapid stride rate comes from shortening the time the foot remains in contact with the ground. When ground contact is brief, the leg can cycle more times per second, boosting cadence and turnover speed. Training that emphasizes quick, light touches, explosive knee drive, and minimizing braking during contact trains this quick ground contact pattern. Prolonged ground contact would slow turnover, increasing braking and reducing cadence. Increasing vertical impulse tends to push more upward rather than forward in a way that promotes faster steps, and increasing stride length without changing contact time shifts focus away from how quickly each step is made. The key idea for a rapid stride rate is to keep ground contact times brief.
