Dual x-ray absorbtiometry, bioelectrical impedance, and near infrared interactance in obese women

Article Abstract:

This article discusses whether low-cost, bedside, two-compartment techniques of testing obese people's body composition are as effect as dual x-ray absorbtiometry (DEXA), bioelectrical impedance (BIA) or near infrared interactance (NII). Results show that correlation coefficients were high, but major differences between fat and lean mass data occurred; the authors conclude that the methods are not interchangeable and question using BIA or NII as a single method when evaluating body composition.

Effect of strength training on resting metabolic rate and physical activity: age and gender comparison

Article Abstract:

This article examines the effect of strength training on resting metabolic rate(RMR), body composition and energy expenditure of physical activity on older and younger men and women. Conclusions reveal that changes in RMR due to strength training are influenced by gender but not by age, and that changes in body composition in response to strength training are not due to other forms of physical activity.
