Lafayette Instrument Skinfold Caliper II Interpretation Without a precise norm for everyone, it seems reasonable to maintain body composition proportions at their level at physical maturity. The average 18-22 year-old male is 15% body fat, and the average female of the same age group is 25% fat. The standard deviation for percent fat is ±5%. Two standard deviation units above the average (25% for men and 35% for women) is generally considered as absolute obesity.
Model 01128 User’s Manual Skinfold Measurement for School-Age Boys and Girls The skinfold test for school age children uses two sites, the triceps and the subscapular, because they are easy to measure and correlate highly with total body fat. The triceps skinfold is measured over the triceps muscle of the right arm, halfway between the elbow and the acromion process of the scapula, with the skinfold parallel to the longitudinal axis of the upper arm.
Lafayette Instrument Skinfold Caliper II Although we know skinfolds are related to body fatness in children, we are yet unable to determine absolute amounts of body fat with certainty. As children mature, the relation of skinfold fat to body fatness changes. Today, national percentile norms are the best frame of reference for interpreting skinfold fat results. The criterion for the wanted degree of fatness in children falls above the 50th percentile.
