On two occasions, seven days apart, female soccer players (N = 12) performed 5 x 11-minute exercise testing blocks, with inter-trial rests of one minute. Each block comprised 11 all-out 20-m sprints, two agility runs, and one precision ball-kicking drill, separated by 20-m walks, jogs, and runs. Ss in a creatine group ingested 5 gm of creatine four times per day, while the placebo group received the same dosage of a glucose polymer.

The creatine group increased in body mass and achieved faster sprint times and agility runs. Shooting accuracy was not affected.

Implication. Creatine supplementation improved physical performance in female soccer players despite an increase in body mass.
