Leucine Metabolites Do Not Enhance Training-induced Performance or Muscle Thickness

ABSTRACTLeucine metabolites, α-hydroxyisocaproic acid (α-HICA) and β-hydroxy-β-methylbutyrate (calcium, HMB-Ca and free acid, HMB-FA), have been proposed to augment resistance training-induced changes in body composition and performance.PurposeWe aimed to conduct a double-blind randomized controlled
