Exploratory study of the relationship of fat-free mass to speed of brain processing in preterm infants

13 November 2013
A new study by the University of Minnesota shows a link in preterm infants between fat free mass (FFM) and neural development, with higher FFM resulting in better neural development. The objective of this study was to assess the relationship between postnatal body composition and brain development as indexed by latency to the P100 peak of the V...

Is body fat percentage a better measure of undernutrition in newborns than birth weight percentiles?

06 November 2013
A new study published on the prestigious Pediatric Research Journal shows that infant morbidity can be predicted more accurately from %fat vs. birth weight. The objective of this study (carried out by Royal Prince Alfred Hospital in Australia) was to describe neonatal morbidity associated with low body fat percentage (BF%) and measure the numbe...

Longitudinal morphological and performance profiles for American NCAA Division I football players

30 October 2013
A new study published on the Journal of Strength and Conditioning provides reference data for collegiate football players %fat over a 4 year college career emphasizing what improvements could be expected given proper training.
