What is the smallest worthwhile change?

The smallest worthwhile change is a calculation used to determine a meaningful change in performance.

In other words, it is the smallest improvement or difference that is worth pursuing, as opposed to a trivial change in performance that might not make a noticeable impact.

Why is the smallest worthwhile change important?

Any person involved in sports, whether that be the sports science or technical coaching staff, or even the athletes themselves, should appreciate the importance of the SWC in regard to fitness testing. Knowledge of this change is important when conducting fitness testing and providing appropriate feedback to coaches and athletes.

When relaying information, the coach must be confident that the measured change in performance is actually meaningful. Calculating the SWC, therefore, allows the coach to be confident that they can accurately determine if a real change in performance has occurred over a subsequent period of time, rather than just a typical variation in the test.
