Total body mass, fat mass, fat-free mass
, and skeletal muscle in older people: cross-sectional differences in 60-year-old persons.
In addition to these, exercise helps maintain fat-free mass
, which in turn helps to maintain higher RMR.
Nine of the 10 species in our study for which fat-free mass
data were available (mean, sample size, min-max, and SD) were significantly heavier than fat-free mass
index in users and nonusers of anabolic-androgenic steroids.
In the absence of clinically relevant DXA cutoffs, the values for fat-free mass
, total body fat and percentage body fat were split according to whether individuals fell above or below the gender-specific median.
Assessment of fat-free mass
using bioelectrical impedance measurements of the human body.
This approach assumes that the fat-free mass
(FFM) in the lower body is proportionally constant relative to the FFM of the whole body and that the measured impedance in the lower body is similar to that of the whole body (1).
She performs a body composition analysis on every patient, every visit, to monitor body fat percentage, fat-free mass
, hydration levels, weight and metabolic rate.
Since he was 44, Forbes has measured his own fat-free mass
on at least 150 separate occasions spanning 37 years.
Some of their increase in fat-free mass
was due to fluid retention.
According to the preliminary findings of the study, those subjects consuming a single serving of Celsius lost significantly more fat mass and gained significantly more fat-free mass
(muscle mass) than those subjects consuming the placebo - a 93.
When compared with other measures including waist circumference (WC), waist-to-height ratio (WtH), percent body fat (%BF), fat mass index (FMI) or fat-free mass
index (FFMI), the researchers found BMI to be as good an indicator of clinical risks as the other measures of body size or composition.
OBJECTIVE: To determine (1) lean and fat body compartments, reflected by fat-free mass
(FFM), appendicular skeletal muscle mass (ASMM), body cell mass (BCM), total body potassium (TBK), fat mass and percentage fat mass, and their differences between age groups in healthy, physically active subjects from 18 to 94 y of age; and (2) if the rate of decrease in any one of the parameters by age might be accelerated compared to others.
The authors adjusted the data for baseline Modified Mini-Mental State Examination (MMMSE) scores, demographics, fat-free mass
, sleep duration, self-reported health and diabetes mellitus.
Cunliffe, The role of diet and exercise for the maintenance of fat-free mass
and resting metabolic rate during weight loss.
