FARAMARZI, M.; NURI, R.; BANITALEBI, E. The effect of short –term combination of HMB (beta-hydroxybeta-
methylbutyrate) and creatine supplementation on anaerobic performance and muscle injury markers in
soccer players. Brazilian Journal of Biomotricity, v. 3, n. 4, p 366-375, 2009. The purpose of this study was to
examine the effects of consumption of HMB (beta- hydroxy-beta-methylbutyrate) and creatine
supplementation on anaerobic performance and muscle injury markers of soccer players. Twenty-four soccer
players from the Iranian soccer first league, at mean age: 20.72 ± 0.70 years, height: 173.33± 4.50 cm, and
weight: 58.60± 5.41kg were selected and randomly divided to three groups: HMB supplementation (n=8),
combination of HMB and creatine (HMBCr) (n=8), and placebo (n=8). Anaerobic performance was assessed
by running anaerobic speed test (RAST), and muscle injury markers measured by serum CK and LDH in the
pre and post tests. Supplementation period was six days. The HMB group received 3gr of HMB supplement
per day, the HMBCr group received 3gr of HMB and 3gr of creatine, and the placebo group received 6gr of
carbohydrate. To investigate the mean differences between pre and post-test variables was used dependent
student t-test. Furthermore, a one –way ANOVA was done among the three groups, to compare the mean
differences of pre and post tests. As there was any significant difference, used the TUKEYs post hock test.
The results showed that peak power increased in both groups of creatine and HMBCr supplementation.
However, there was significant increase only in HMBCr group (p=0.02). Furthermore, after comparing the groups, there was a significant difference between HMB and HMBCr supplementation group (p=0.036).
Mean power increased in, HMB and HMBCr groups. But, this was significant in HMBCr group (p=0.014),
only. Although, fatigue index showed the small changes in the three groups, there was no significant
difference. Also, the mean of serum LDH and CK was decreased. This however, was no significant in any of
the groups. In conclusion, the results of this study showed that due to the relative increase in anaerobic
performance of soccer players, HMBCr supplementation can lead to increase of anaerobic performance.
