The aim of this study was to determine the effect of creatine supplementation on sprint and skill performance in young soccer players. Seventeen young soccer players (mean age: 17.18 ± 1.37 y, mean high: 169.6 ± 6.17 cm and mean weight: 61.67 ± 1.37 kg) participated in this study. Subjects were assigned to either a creatine (5 g of Cr, 4 times per day for 7 days) or a placebo group (same dosage of a glucose polymer) using a double-blind research design. Subjects performed a repeated sprint test, a dribble and an accuracy of shooting to a target zone tests, before and after supplementation. Results showed that the weight and lean body mass increased significantly in the creatine group (P<0.05), but, means difference between two groups were not significant. On the other hand, results showed that the time of sprint running test and dribbling decreased significantly in the creatine group (P<0.05), that mean differences between two groups, also, were significant (P<0.05). For accuracy of shooting, no significant difference was observed (P >0.05). In conclusion, creatine supplementation improved performance of repeated sprint and dribble in young soccer players.کلیدواژه ها:
