In this randomized, double-blind, placebo-controlled study, 20 elite paddlers were supplemented with HMB or placebo during a strength training period. Researchers evaluated body composition, athletic performance, and markers related to muscle stress. The HMB group showed increases in lean body mass, reductions in CK and LDH, and improved official race time. The study suggests HMB may help support training adaptations and reduce markers of muscle damage in high-performance athletes.
