Why should skinfold measurements not be taken after exercise?

1. They provide more accurate results

2. The transfer of fluid to skin causes overestimation

3. They are quicker to perform

4. They require specialized equipment

The correct answer is: The transfer of fluid to skin causes overestimation

Skinfold measurements are a method used to assess body fat percentage by measuring the thickness of skinfolds at various body sites. It is essential to consider physiological changes that occur in the body during and after exercise. After exercise, the body experiences an influx of fluids toward the skin, which can lead to an overestimation of skinfold thickness. This is due to increased blood flow and fluid accumulation in the skin, making the measurements less reliable. When skinfold measurements are taken when the body is in a rested state, they are more stable and reflect the true subcutaneous fat levels rather than being influenced by temporary changes caused by exercise. Therefore, waiting until after an appropriate recovery period is essential for obtaining accurate readings, ensuring that the data collected reflects true body composition rather than transient factors related to recent physical activity. In contrast, options regarding accuracy, speed, and equipment do not directly address the physiological impact of exercise on skin assessments, making them less relevant in this context.
