Abstract des Autors
We examined relationships bewteen skinfold (SKF) and optimal density (delta OD) measurements across age and levels of body fatness (BF) for 151 women, 20 to 72 years. There were significant (p<.05) relationships between delta ODs and SKFs at all sites, except the thigh. The interaction (SKF x Age) was significant (p<.05) for pectoral and biceps delta ODs. Slope comparions indicated the relationships for younger (29 years) and older (50 years) women differed significantly from zero and each other (p<.05). Analysis of SKF x BF interactions revealed that relationships between SKFs and delta ODs at the pectoral and biceps sites for leaner (22 BF) women differed significantly from zero (p<.05) and were larger than those for obese (39 BF) women (p</-.05). Thus, the relationship between SKFs and delta ODs is stronger for younger and leaner women compared to older and fatter women. These findings may reflect differences in fat layering due to age or body fatness and provide insight as to why the manufacturers near-infrared (NIR) equation significantly underestimates the BF of obese women.
