ACE Health Coach Certification Practice Test

What are the two primary sources of error in performing skinfold measurements?

1. Improper site determination and improper equipment calibration

2. Improper site determination and improper measurement techniques

3. Improper calculation and lack of experience

4. Improper documentation and environmental influence

The correct answer is: Improper site determination and improper measurement techniques

The primary sources of error in skinfold measurements primarily relate to the techniques used and the specific locations on the body where the measurements are taken. Improper site determination refers to challenges in accurately locating the prescribed anatomical sites for skinfold measurements, which are critical for ensuring the validity and reliability of the results. Each measurement site is chosen based on specific anatomical landmarks, and if these landmarks are not correctly identified, the measurements can be inconsistent or inaccurate. Improper measurement techniques involve the method of pinching the skinfold and reading the caliper. It requires consistent pressure, body positioning, and the ability to grasp the skinfold correctly to avoid errors. Any deviations in these techniques can lead to significant discrepancies in the data collected. Together, these factors can cause variability in skinfold measurement outcomes, impacting body composition assessments. Proper training and understanding of these components are essential for a health coach to achieve accurate and reliable results in skinfold assessments.
