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.

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 ...

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.

Body fat mass in hemodialysis patients

American Journal of Kidney Diseases, 2003
Changes in body fat mass in a large number of hemodialysis patients is unknown.Body fat mass and lean body mass were measured by dual x-ray absorptiometry (DXA) in 561 patients with hemodialysis duration less than 180 months (62.3 +/- 11.5 years old; mean +/- SD).Fat mass tended to increase during the first 3 years of hemodialysis, and it tended to ...

Body Fat Mass, Leptin and Puberty

Journal of Pediatric Endocrinology and Metabolism, 2000
Leptin, the ob gene product, provides a molecular basis for the lipostatic theory of the regulation of energy balance. Leptin circulates as a monomeric 16 kDa protein in rodent and human plasma and is also bound to leptin binding proteins that may form large high molecular weight complexes.

Changes in fat mass and fat-free mass during the adiposity rebound: FLAME study

International Journal of Pediatric Obesity, 2011
To determine the changes in body composition from 3 to 7 years of age in children undergoing adiposity rebound (AR) at different ages.Body composition was measured bi-annually by bioelectrical impedance in 229 children from a birth cohort. Age at AR was calculated from changes in weight and height velocity over time. Early AR was defined as < 6.1 years

Factors that alter body fat, body mass, and fat-free mass in pediatric obesity

Medicine & Science in Sports & Exercise, 2002
The purpose of this study was to quantify the effects of exercise treatment programs on changes in body mass, fat-free mass, and body fat in obese children and adolescents.By using the meta-analytic approach, studies that met the following criteria were included in our analyses: 1) at least six subjects per group; 2) subject groups consisting of ...

Relationship of fat mass and fat distribution to blood pressure

Diabetes Research and Clinical Practice, 1990
The relationship of fat mass, lean body mass (LBM), and fat distribution to blood pressure was examined in Japanese adult men and women. Percent body fat was estimated using two skinfold thicknesses, and fat mass and LBM were then calculated. Correlation coefficients showed that fat mass, fat distribution, and age were weakly associated with blood ...

[Fat mass and fat free mass on ventilatory function in adults].

Sheng li xue bao : [Acta physiologica Sinica], 2013
This study is designed to probe for the effects of fat mass (FM) and fat free mass (FFM) on ventilatory function in adults. 1 307 healthy adults (372 males and 935 females) were selected from some localities of Heilongjiang province through random sampling by means of questionnaire and physical examination and measured for height, weight, waist to hip ...
