HMB Supplementation Effects on High-Resolution Skeletal Muscle Diffusion Tensor Imaging and Intramyocellular Fat Changes during High Intensity Military Training Academic Article uri icon


  • The purpose of this study was to examine the effect of β-hydroxy-β-methylbutyrate Free Acid (HMB) supplementation on muscle morphological and muscle lipid changes during highly intense military training. Thirteen soldiers from an elite combat unit were randomly assigned to either a HMB (n= 6) or placebo (PL; n= 7) group. Soldiers were provided with 3 g· day− 1 of either HMB or PL for 23 days. During the final week of supplementation (days 18–23) soldiers participated in extreme physical training, which included night navigation of 6–8 hours across difficult terrain with approximately 35 kg of equipment on their back. During daylight hours, soldiers remained in camouflaged positions with minimal recovery. Due to a severe environmental stress (37 C and a sand storm) navigational training was performed on only the first two evenings of the week. Still, soldiers continued to be subjected to …
