Abstract

The purpose of the current study was to validate the use of B-mode ultrasound as a method to estimate body composition in Division I football players. Body composition was estimated using ultrasound, 7-site skinfold and a 4 compartmental model (4C) using Bioimpedance spectroscopy (BIS) to estimate total body water (TBW) and air-displacement plethysmography (BODPOD®) to determine body density (Db) and dual x-ray absorptiometry (DEXA) for bone mineral content. Pearson’s product-moment correlation analyses were run to determine if there was a correlation between ΣSkinfold and ΣUltrasound and between ΣUltrasound and criterion 4C model. Strong positive correlations were observed between ΣSkinfold and ΣUltrasound (r= .926; p.05). SEE and validity coefficient (r) were 1.81% and 0.91, respectively, with a total error (TE) value of 2.32%. Conclusion: This study supports the use of B-mode ultrasound as a method to predict body composition in Division I football players.
