Final answer:
There are two different combinations used for skinfold measuring in kids: the 3-site method and the 7-site method.
Step-by-step explanation:
In kids, there are two different combinations used for skinfold measuring, known as the 3-site method and the 7-site method.
The 3-site method involves measuring the thickness of skinfolds at three specific locations: the triceps, subscapular, and suprailiac sites. These measurements are then added together to estimate body fat percentage.
The 7-site method is more comprehensive and involves measuring the skinfolds at seven different locations: triceps, biceps, subscapular, iliac crest, abdominal, thigh, and calf. The sum of these measurements is used to calculate body fat percentage.
