The impact of subject positioning on body composition assessments by air displacement plethysmography evaluated in a heterogeneous sample.

Introduction: This study sought to evaluate the impact of subject positioning on body composition assessments by air displacement plethysmography using the BOD POD®.

Methods: Eighty-two adults (42 men and 40 women), aged 26.1 ± 8.

Reliability of body composition assessment using A-mode ultrasound in a heterogeneous sample.

Background/objectives: Several studies have addressed the validity of ultrasound (US) for body composition assessment, but few have evaluated its reliability. This study aimed to determine the reliability of percent body fat (%BF) estimates using A-mode US in a heterogeneous sample.

Subjects/methods: A group of 144 healthy adults (81 men and 63 women), 30.
