The use of the two components of BMI (BFMI and FFMI) makes it possible to assess whether BMI differences between age categories are linked to the variations of fat mass or fat-free mass [18] and to calculate the proportion of players classified as normal-weight, overweight, and obese by BMI having an excess adiposity by BFMI above the 75th percentile [22].
Body weight and BMI measures may not capture variations of fat mass and lean mass among women.
Differences exist among sampling localities in terms of food availability, causes of variations of fat content, and hence varying accumulation potential in fish.
Our results could be helpful in further understanding the genetic interaction between candidate genes contributing to phenotypic variation of abdominal fat content in broilers.
A large proportion of variation of intramuscular fat content of the M. longissimus at the myostatin locus could be explained by sex (23%) and direction-of-cross effects (26%).
Examples of these situations include the DGAT1 gene and the SCD gene on bovine chromosomes 14 and 26 which contribute a large proportion of the genetic variation of milk fat content [ 23, 24] and the IGF2 gene on porcine chromosome 2, which contributes a large proportion of the genetic variation of muscle mass in pigs [ 25].
MRS scans were performed at the time of screening, on average 51 days before the tracer studies, but the intrasubject coefficient of variation of liver fat measurements has previously been estimated to be low (8.5%) (39) and there was no change in body weight between study visits.
Differences in lifestyle factors, limbs, trunk, and stature proportionality, and in ethnic variations of body fat distribution in relation to BMI have been debated [ 11].
The intra-observer coefficient of variation for the percentage of fat mass estimates is 0.3%.
We analyzed the variation of the amount of fat mass and non-fat mass (lean mass) before and after the 6-day treatment of CL316243 and OEA using a nuclear magnetic resonance imaging (Whole Body Composition Analyzer, EchoMRI, Houston, TX) (Imbernon et al., 2013).
