In the last two decades, the use of supplements to improve sports performance has become widespread among young athletes. Considering the existing contradictions in the field of these supplements, the present study investigated the effect of short-term consumption of creatine and creatine-carbohydrate supplements on anaerobic power and muscular endurance of semi-professional male martial artists. In this regard, 15 martial artists were selected purposefully. In the first week of the study, loading of creatine supplement (0.3 grams per kilogram of body weight per day) was done for 5 days along with 3 sessions of resistance training. After one month, in the second week of the study, creatine-carbohydrate supplement loading (0.3 grams of creatine + 1.5 grams of carbohydrates per kilogram of body weight per day) was performed for 5 days along with 3 sessions of resistance training. To measure anaerobic power and muscular endurance, Sargent's jump test and sitting test was performed respectively, before and after loading the supplements on each of the subjects. The results were analyzed using descriptive statistics and inferential statistics (correlated t and independent t) with the help of Spss software version 16. The results showed that the short-term consumption of both the creatine and creatine-carbohydrate supplements improved and increased the anaerobic capacity of the subjects (P < 0.05); however, the short-term consumption of neither creatine nor creatine-carbohydrate supplements had no effect on muscular endurance (P < 0.05). In addition, compared to creatine-carbohydrate mixture, short-term consumption of creatine supplement had no significant difference on anaerobic power and muscle endurance.
