ACE Personal Trainer Practice Exam

If a client pulls their knee toward their chest too far, resulting in a posterior pelvic tilt, what does it result in?

1. A false positive of the test

2. A false negative of the test

3. Indication of strong hip flexors

4. Assessment of lordosis

The correct answer is: A false negative of the test

When a client pulls their knee toward their chest too far and experiences a posterior pelvic tilt, it can lead to a false negative of a specific test aimed at assessing flexibility, strength, or mobility in the hip or lower back region. A false negative occurs when the test fails to identify an issue or limitation that is actually present. In this case, the excessive knee lift may compensate for a lack of mobility in the lower back or hips, misleading the tester into concluding that the client has adequate flexibility or strength when, in reality, the posterior pelvic tilt suggests otherwise. This compensation means that the true functional capabilities of the hip flexors and surrounding musculature may not be accurately represented during the assessment. Understanding this mechanism is important as it highlights the importance of proper form and alignment during assessments to ensure that any underlying issues are correctly identified and addressed in training programs.
