This study examined the effects of HMB free acid (HMB-FA) supplementation and cold water immersion (CWI) on recovery in 40 resistance-training men post high-intensity lower body training. HMB-FA and HMB-FA combined with CWI resulted in significantly lower C-reactive protein levels during recovery. More importantly HMB free acid combined with CWI resulted in a significant improvement in power per repetition. The authors concluded that HMB-FA combined with CWI improved performance recovery after the acute bout of exercise.
