The aim of this study was to evaluate the effect of HMB-FA supplementation on inflammatory parameters during a two-race microcycle in Soccer players.

A total of 24 Soccer players (mean age: 23±30 years) were randomly divided into two groups supplement (n = 12) and placebo (n = 12). Subjects in the supplement group and the placebo group participated in a weekly microcycle with two races per week. Subjects in the supplement-training group consumed three grams of HMB-FA daily during a weekly soccer cycle. Serum levels of inflammatory markers of interleukin-1 beta, interleukin-6 and reactive protein-C in seven stages (before supplementation, before the first race, after the first race, 24 hours after the first race, before the second race, after from the second race, 24 hours after the second race) were evaluated. For data analysis, repeated measures test and paired t-test and SPSS software version 25 were used. Significance level was considered α = 0.05.

The results of the present study showed that training and two Soccer matches increased all inflammatory indices (for all, P≤0.05).

Consumption of HMB-FA supplement reduces inflammatory factors during a two-match Soccer microcycle, which shows the ability of this supplement to control the inflammatory status of Soccer players in inflammatory conditions caused by two matches per week.

It seems that the use of nutritional supplements can affect the secretion of anabolic and catabolic hormones during exercise-recovery process. The purpose of the present study was to determine the effect of beta-hydroxy beta methyl butyrate supplement in free acid form (HMB-FA) on hormonal responses and recovery in the wrestling-specific protocol (WSP) in wrestlers for one night and one day.

Twenty male wrestlers were selected and randomly divided into two groups: supplement-exercise (n=10) and placebo-exercise (n=10) groups. Each of the groups received a supplement or placebo at 3 g/day. The subjects repeated the WSP five times, each consisting of four sections. To measure serum insulin-like growth factor-1 (IGF-1), and cortisol (Cort), IGF-1/Cort ratio blood samples were taken before and after taking the supplement, immediately after the first repetition of the WSP, immediately after the third repetition of the WSP and immediately after the fifth repetition of the WSP. The perceived recovery status (PRS) was assessed immediately before the first, second, third, fourth, and fifth repetitions of the WSP. Results were extracted using analysis of covariance and analysis of variance with repeated measures at a significance level of p<0.05.

The results showed that serum levels of IGF-1 after supplementation (p=0.001) and after the first (p=0.004), third (p=0.004) and fifth (p=0.01) of the WSP were significantly higher in HMB-FA group than placebo group. Moreover, serum levels of IGF-1/Cort after supplementation (p=0.001) and after the first (p=0.001), third (p=0.003) and fifth (p=0.001) of the WSP were significantly increased in the HMB-FA group as compare to the placebo group. However, cortisol indicated a higher increase in the placebo group than HMB-FA group after supplementation (p=0.006) and also after first (p=0.002), third (p=0.008) and fifth (p=0.002) of WSP. On the other hand, PRS in the placebo group showed a greater decrease than the HMB-FA group before the first, second, third, fourth, and fifth of WSP (p<0.05).

It seems that HMB-FA supplementation improves hormonal responses during the simulated wrestling protocol.
