What are the three primary phases observed in a 40-yard dash?

• A. Start, Acceleration, End
• B. Pre-sprint, Sprint, Recovery
• C. Start, Midstance, Finish
• D. The Start, Transition Phase, Max Velocity Phase

Answer: (D)

In a short sprint, you can clearly divide the mechanics into three stages: the start, the Transition Phase, and the Max Velocity Phase. The start is the explosive push from the crouched stance, focused on rapid force application and getting the body moving forward as quickly as possible. As you accelerate, you move into the Transition Phase, where the body shifts from trying to brake against inertia to increasing forward momentum—your posture becomes more upright, stride length begins to lengthen, and your cadence rises while you reduce braking forces. Then you reach the Max Velocity Phase, where you achieve and briefly maintain your top speed, optimizing leg turnover and stride mechanics to stay at peak velocity.

This sequence fits a 40-yard dash well because the distance is short enough that runners typically hit near-max speed within the first 20–30 yards and hold it for a portion of the sprint before fatigue or form decay occurs. Other descriptions don’t align as neatly with sprint mechanics: one option uses a general or non-sprint-specific term, another relies on a stance word from gait analysis rather than sprint phases, and another splits into pre-sprint or recovery rather than the actual sprint mechanics.
