When males and females are combined, individuals with FSHD had lower appendicular lean mass (ALM), arm lean mass and leg lean mass but greater body and leg fat mass. When separated by sex, only males with FSHD exhibited a significant difference in these measures. kg: kilogram; data are presented in mean ± SD.
