The effect of short-term consumption of HMB supplementation on CK, LDH after eccentric resistance exercise in young male athletes

Introduction and The aim of the study was to examine the effect of short-term consumption of HMB supplementation on CK and LDH after eccentric resistance exercise in young male athletes. Twenty-four young male futsalplayer were selected and randomly divided into two groups of 12 of supplementation and placebo. Subjects consumed HMB or placebo for 6 days before a session of eccentric resistance exercise. Blood samples were taken to measuring CK and LDH in 4 times. The results showed that the effect of HMB supplementation on two markers of muscle damage (CK and LDH) is not significant but HMB supplementationcaused a significant reduction in both markers of muscle damage (CK and LDH) after eccentric resistance training on supplementation groupDiscussion and HMB supplementation can decrease markers of muscle damage، but the results cannot be used as functional supplements to reduce muscle damage markers caused by intense physical activity
