What is a common test for assessing linear speed?

The 40-yard dash is widely recognized as a standard test for evaluating linear speed, particularly in sports and athletic training. This test is particularly popular in football and track and field, as it measures the maximal speed an athlete can achieve over a short distance. Timing the sprint from a stationary start allows for an assessment of acceleration as well as top-end speed, which are critical components of athletic performance.

In contrast, other options assess different aspects of athletic ability. The 100-meter sprint is longer and focuses more on endurance and speed over a greater distance. The standing long jump evaluates explosive leg power rather than speed, while the vertical jump test measures vertical leap ability and leg strength, not linear speed. Therefore, the 40-yard dash effectively isolates the skill of running speed in a short, intense effort, making it the most suitable choice for assessing linear speed among the provided options.
