BACKGROUND: A correlation between adiposity and post-exercise autonomic regulation has been established in overweight and obese children. However, little information exists about this link in non-obese youth. The main purpose of this cross-sectional study was to describe the relationship between body fat percentage (BFP) and heart rate recovery after exercise [post-exercise heart rate (PEHR)], a marker of autonomic regulation, in normal-weight children and adolescents. METHODS: We evaluated the body composition of 183 children and adolescents (age 15...

BACKGROUND: We aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM). METHODS: Air-displacement plethysmography (PEA POD) was used to estimate FM, FFM and body fat percentage (BF%). Associations between FFM, FM and BF% and weight/length, BMI and PI were evaluated in 1,019 newborns using multivariate regression analysis. Charts for FM, FFM and BF% were generated using a prescriptive sub-sample (n=247)...

Dual-energy X-ray absorptiometry (DXA) provides a noninvasive way to determine lean tissue mass (LTM), fat mass (FM), bone mineral content (BMC), and bone mineral density (BMD) in humans and small mammals. Live channel catfish (n=74, 78g - 1200 g) were anesthetized and scanned in both a lateral position and a dorsa-ventral position. Six individual fish (300g - 600g) were scanned five times each to determine precision by the coefficient of variation. Precision was good for LTM (0.75-1.06%) and for BMC and BMD (2-2...
