How is acceleration speed primarily measured?

Acceleration speed is primarily measured by the time taken to complete a specific distance, such as a 30m dash. This method allows for a direct calculation of how quickly an athlete can reach a certain speed from a standstill or low velocity, focusing on the initial phase of motion. Acceleration is defined as the rate at which an object changes its velocity, and the 30m dash provides a short, controlled environment where the measurement can accurately reflect this change.

In contrast, measuring acceleration using overall race completion time does not isolate the acceleration phase and may include other factors such as strategy, endurance, and speed maintenance. Similarly, considering the distance of 100m doesn't target the acceleration segment specifically, as it would involve longer sprinting, which could include different phases of speed. The number of sprints in a workout might indicate an athlete's training volume but does not provide direct insight into their acceleration capability or speed measurement in a given distance.
