When in a sprint is acceleration typically observed?

Acceleration in a sprint is primarily observed within the first 10 meters of the race because this phase is crucial for achieving maximum speed. During the initial moments of a sprint, athletes are transitioning from a stationary position to full speed. The body undergoes progressive force application to the ground, propelling the runner forward while they are still building up speed.

In this early phase, the athlete uses explosive strength and technique to maximize acceleration before reaching the top running speed, which is typically established within the first 30 meters. It's during these first few meters that effective sprint mechanics, including powerful leg drive and optimal body positioning, come into play, allowing for significant increases in velocity. By the time athletes reach later distances in the race, such as near the finish line, they are generally at or near their maximum speed and may not experience the same level of acceleration as during the initial phase. This makes the observation of acceleration most pronounced within the first 10 meters.
