Thus, body composition assessment and evaluation are important and necessary to meet the duties and responsibilities of the Armed Forces. APPROACHES Because of the large numbers of military personnel that require body composition assessment, any approach must acknowledge and balance the factors of practicality, reliability and accuracy of measurements, time requirements, and skill required by the test administrator.

or the combination of skinfold thicknesses and body circumference measurements (Clark, 1976~. Each of these anthropometric approaches relies on regression equations to predict percent body fat (BF)

It is unclear from the available literature whether the military body composition program intends to establish norms and standards for the individual or for the armed forces as a whole. With the current system of weight-for-height tables, body circumference measurements, and an allowable increase of 2 percent BF standards per decade of age, it appears that population assessment methods are used for screening, and individual standards are used for evaluation.

Realistic consideration of attainable changes in body weight and body composition during recruit training should be included in deriving weight estimates for recruitment and retention of military personnel. Evidence from the military application of anthropometric approaches to predict densitometrically determined body composition variables indicates that models for predicting percent BE by using either skinfolds and body circumferences (Clark, 1976)

The potential impact of the problem of ethnic or racial differences in body composition is magnified by the use of inadequate reference and candidate measurements of body composition. Currently, underwater weighing or hydrodensitometry is the reference method used in body composition surveys of military personnel to develop anthropometric models.

In addition, most prediction equations based on skinfold thicknesses are population specific (Edwards, 1951; Jackson, 1984; Lukaski, 1987~. These factors limit the use of skinfold thickness measurements for precisely and accurately estimating body composition in the heterogeneous military population.

The variability of the distribution of the relationship between measured and predicted percent BF values from the military trials using neck and abdominal circumference measurements and height is summarized in Table 1 1-4. It is clear that the standard errors of the estimate of percent BF are quite large and exceed the theoretical precision of the densitometric method (Lohman, 1981~.

· Use a multicompartmental model of body composition, and include measurements of bone mineral density (regional and total body) to correct apparent whole body density obtained by underwater weighing.
