How many measures should be taken at each skin fold site?

Taking two measurements at each skin fold site is standard practice in body composition assessment using skinfold calipers. This approach helps to ensure accuracy and reliability in the measurements. The rationale behind taking two measurements is to minimize the impact of any potential errors that may arise from variations in technique, skin tension, or the subject's response during the measurement process.

By averaging the two measurements, you can reduce the likelihood of an outlier skewing the overall assessment. This method also allows the trainer to detect consistent readings across the two attempts, which boosts confidence in the accuracy of the data being collected. If the two measurements differ significantly, a third measurement might be taken, but the initial guideline of two is established to maintain consistency and ensure a more reliable estimate of body fat percentage.

In contrast, taking just one measurement might not provide a comprehensive view of the individual's body composition status, while more than two could introduce unnecessary complexity and time into the assessment process.
