Note:
AKA, athletes with unilateral lower limb amputation above the knee; BKA, athletes with unilateral lower limb amputation below (or through) the knee; SD, standard deviation; g, Hedges’g; %FM, percentage fat mass; FM/LM, fat-to-lean mass ratio; BMD, bone mineral density. Statistically significant differences are in bold.
