In a Flying 30 test, the 20 m run-up into the 30 m maximal sprint primarily measures what?

• A. To ensure complete rest before the 30 m sprint.
• B. To create a controlled acceleration into the maximal sprint.
• C. To measure endurance across repeated sprints.
• D. To test reaction time from a standing start.

Answer: (B)

The Flying 30 is about capturing maximal sprint velocity, so the 20 m run-up is used to build up speed before the measured portion. This setup creates a controlled transition into the maximal sprint, meaning the 30 m section reflects how fast the athlete can move once fully up to speed rather than how quickly they can start. It also reduces the influence of reaction time and starting technique on the result.

So the run-up’s purpose is to create that controlled acceleration into the maximal sprint, not to rest, test endurance, or measure standing-start reaction time.
