ABSTRACT
Numerous studies conducted over the past 70 years provide a large body of knowledge and evidence that simple methods of quantifying body size and proportions can be used in many settings to predict body composition and regional fat distribution. This section discusses the strengths, weaknesses, and potential best applications of three field anthropometric methods: frame size, skin folds, and circumferences. These methods have been widely studied and are commonly used because they yield valid and reliable results when applied correctly and because they are noninvasive, inexpensive, portable, and relatively simple to perform.
