This study aimed to determine the reliability of percent body fat (%BF) estimates using A-mode ultrasound (US) in a heterogeneous sample of 144 healthy adults. Six consecutive measurements were taken at eight anatomical sites by two testers using a BodyMetrix™ instrument. Four formulas from BodyView™ software were used to compute %BF. The 7-sites Jackson and Pollock formula showed the highest reliability (ICC = 0.979-0.985, TEM = 0.89-1.07% BF, MDC = 2.47-2.95% BF). Intertester bias was -0.5% BF, with an ICC of 0.972. A-mode US is highly reliable for %BF assessment, but more precise for men than women. Examiner performance impacts precision.
