Abstract
  • Identifying valid field methods to measure body composition in overweight and obese individuals is essential for quantifying percent body fat (%BF), fat mass (FM) and fat free mass (FFM) and the associated concomitant health consequences. The purpose of this study was to compare the validity and reliability of an A-mode ultrasound (US) to the criterion three compartment model (3C) for the measurement of body composition in overweight and obese subjects. Body composition testing was performed on forty-seven overweight and obese subjects via the ultrasound, air displacement plethysmography and bioelectrical impedance spectroscopy, on two separate days. The US was not found to be a valid measurement of body composition in overweight or obese individuals; %BF and FM was significantly under-predicted, while FFM was over-predicted when compared to the criterion 3C model. The US was found to be reliable when compared to 3C for measuring %BF
