BACKGROUND: This study critically appraises the measurement properties of tools to
measure muscle mass, strength, and physical performance in community-dwelling older …

Direct visualization of metabolic dynamics in living animals with high spatial and temporal
resolution is essential to understanding many biological processes. Here we introduce a …

Heavy water is an ideal contrast agent for metabolic activity and can be adapted to a wide
range of biological systems owing to its non-invasiveness, universal applicability, and cost …

Objective To design and validate a predictive BIA equation to estimate ASM in a sample of
non-Caucasian older people and to explore the accuracy of two previous single-frequency …

Métodos: se relacionaron los datos del Mini Nutritional Assessment (MNA), la impedancia
bioeléctrica (BIA), las medidas antropométricas y los indicadores de actividad física con los …

Background The body mass index (BMI)≥ 30 kg/m 2 is the universally accepted cut-off point
for defining obesity; however, its accuracy in classifying obesity in older adults is poorly …

Background The study of body composition in specific populations by techniques such as
bio-impedance analysis (BIA) requires validation based on standard reference methods …

Bioelectrical impedance analysis (BIA) models must be validated against a reference
method in a representative population sample before they can be accepted as accurate and …

Objective Several limitations of published bioelectrical impedance analysis (BIA) equations
have been reported. The aims were to develop in a multiethnic, elderly population a new …

Objective: The objective of this study was to assess total energy expenditure (TEE), resting
metabolic rate (RMR) and physical activity level (PAL), and to estimate energy requirements …
