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.
