What does test validity ensure?

Test validity ensures that a test accurately measures what it is intended to measure. In the context of bodybuilding or fitness assessments, validity is crucial because it confirms that the results you obtain from the test truly reflect the characteristics, skills, or attributes you are trying to evaluate. For instance, if you are assessing muscular strength, a valid test would assess that specific component rather than being an unrelated measure, such as agility.

A valid test provides meaningful and relevant data that can be acted upon, guiding training and performance improvements. This is particularly important in sports sciences and bodybuilding, where precise measurements can significantly influence training decisions and outcomes.
