What factor most influences the accuracy of skin-fold measurements?

The accuracy of skin-fold measurements is highly dependent on the skill and experience of the individual taking the measurements. A skilled professional will have a thorough understanding of how to properly locate skin-fold sites, apply the caliper correctly, and ensure consistent technique across all measurements. This professional proficiency is crucial as even small variations in technique can lead to significant differences in the readings.

Other factors, while still important, do not have as pronounced an impact on the accuracy of the measurements as the skill of the person taking them. The type of caliper used can influence the measurement quality, but a proficient operator can often compensate for equipment variability. Similarly, while the timing of the day and the client’s hydration status can affect body composition readings, these factors usually have a lesser influence compared to the technique and expertise of the person conducting the assessment.
