Abstract:
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.

Subjects performed a repeated sprint test, a dribble and an accuracy of shooting to a target zone tests, before and after supplementation.
In addition there is a shortage of scientific data concerning the possible effects of oral creatine-monohydrate supplementation on specific performance in sport such as soccer (Ostojic.
Performance improve of speed and skill in different fields of sports such as wrestling, sprinting and volleyball and after complementary use of creatine have been experimented (Volek et al.
Methods Subjects In this experiment 17 young soccer players from the squad of first batch were selected and they were organized (in terms of endurance and speed performance, body mass index and playing position) in two groups of creatine (n=8) and placebo (n=9).
Results from this study can concluded that short-term consumption of creatine supplementation is effective in improvement of performance, speed and skill of young soccer player.
