How long should skinfold readings be held during testing?

1. 2-3 seconds

2. 1-2 seconds

3. 3-4 seconds

4. 5-6 seconds

The correct answer is: 1-2 seconds

The appropriate duration for holding skinfold readings during testing is 1-2 seconds. This timing allows for an accurate measurement while ensuring that the skinfold caliper pressure does not compress the skin excessively, which could alter the reading. It is important to minimize any influence from the tester's actions on the skinfold measurement itself; therefore, allowing a brief hold helps provide a consistent and reliable measure of subcutaneous fat thickness. Holding for too long could potentially lead to misrepresentation of the actual skin thickness, as the tissue might begin to deform or change under the consistent pressure of the caliper. Understanding this technique is crucial for personal trainers when assessing body composition, as accurate skinfold measurements are essential for determining body fat percentage and tracking clients' progress effectively.
