Effect of Creatine Supplementation on Sprint and Skill Performance in Young Soccer Players مقاله



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.
