The relationship between body fat mass and fat-free mass.

Journal of the American College of Nutrition, 1991
It has been suggested that there is a curvilinear relationship between lean body or fat-free mass and body fat mass. In order to confirm this relationship, body composition was measured by determining body density and total body water using deuterium-labeled water in subjects varying widely in body fat mass. There were 29 males and 75 females with body

Prediction of resting energy expenditure from fat-free mass and fat mass

The American Journal of Clinical Nutrition, 1992
On the basis of literature values, the relationship between fat-free mass (FFM), fat mass (FM), and resting energy expenditure [REE (kJ/24 h)] was determined for 213 adults (86 males, 127 females). The objectives were to develop a mathematical model to predict REE based on body composition and to evaluate the contribution of FFM and FM to REE.

Left ventricular mass correlates with fat-free mass but not fat mass in adults

Journal of Hypertension, 1999
Left ventricular mass is associated with body size, obesity and blood pressure. Echocardiography is routinely used to estimate this parameter, which is usually indexed to body surface area to allow comparisons to be made between individuals and groups of different body size.

Prediction of Fat-Free Mass in Children

Clinical Pharmacokinetics, 2015
Fat-free mass (FFM) is an important covariate for predicting drug clearance. Models for predicting FFM have been developed in adults but there is currently a paucity of mechanism-based models developed to predict FFM in children.The aim of this study was to develop and evaluate a model to predict FFM in children.A large dataset (496 females and 515 ...

Fat-Free Mass as a Function of Fat Mass and Habitual Activity Level

International Journal of Sports Medicine, 1992
The best predictor of energy expenditure in man is the fat-free mass of the body. Fat-free mass explains most of the variation in resting metabolic rate and even in total metabolic rate under sedentary conditions. We studied possible determinants of fat-free mass as routes to influence energy metabolism.

Fat-free mass and fat mass in active boys during adolescence

American Journal of Human Biology, 1997
Longitudinal body composition data were examined in 24 active and 10 control boys between the ages of 12.3 and 15.3 years. The main objectives were (1) to contrast the distance and velocity curves of fat-free mass (FFM) and fat mass (FM) in active and control groups using chronological and maturity bases, and (2) to compare the timing and magnitude of ...

Magnetic resonance imaging-measured skeletal muscle mass to fat-free mass ratio increases with increasing levels of fat-free mass

The Journal of Sports Medicine and Physical Fitness, 2019
To investigate the skeletal muscle mass to fat-free mass (SM-FFM) ratio in female and male athletes, as well as to examine the relationship between ultrasound predicted SM and magnetic resonance imaging (MRI)-measured SM.Seven female track and field athletes (female), 8 male collegiate swimmers (male-G1) and 8 male collegiate Olympic weightlifters ...

Differential impacts between fat mass index and fat-free mass index on patients with COPD

Respiratory Medicine, 2023
Differences in the clinical impacts of fat mass index (FMI) and fat-free mass index (FFMI) remain unclear in patients with chronic obstructive pulmonary disease (COPD). We hypothesized that FMI and FFMI have different impacts on 1) emphysema and 2) pulmonary function and health-related quality of life of COPD patients.Patients with COPD (n = 228 ...
