Effect of HMB-FA Supplementation on Muscle damage indices in a Simulated Wrestling Protocols in elite wrestlers

The purpose of the current study was to investigate the effect of HMB-FA supplementation on muscle damage indices in elite wrestlers. A total of twenty wrestlers selected in two supplement- exercise (n=10) and placebo- exercise (n=10) groups to participate in a simulated wrestling protocol. Subjects were randomly assigned to receive either 3g/d of HMB-FA or a placebo. Blood samples to measure serum creatine kinase (CK) and lactate dehydrogenase (LDH) were taken before taking the supplement, after taking the supplement, immediately after the first repetition of the simulated wrestling protocol, immediately after the third repetition of the simulated wrestling protocol, immediately after the fifth repetition of the simulated wrestling protocol. The perceived recovery status (PRS) was assessed immediately before the first, second, third, fourth, and fifth repetitions of the simulated wrestling protocol. The results were analyzed using ANCOVA analysis of covariance and analysis of variance with repeated measures. The results of this study showed that the values of muscle damage indices, including CK, LDH decreased significantly more than the placebo group in the HMB-FA group (p<0.05). There was also a significant change for PRS, which significantly decreased in the placebo group compared to HMB-FA (p<0.05).Therefor, it can be concluded that HMB-FA supplementation appears to improve muscle damage indices in wrestlers' simulated wrestling protocol.
