The purpose of this study is to determine the effects of creatine loading on
performance of amateur soccer players who were given 20 gr of creatine on a daily basis in
period of 5 days.
In this study, 21 volunteer male soccer players of A.I.B.U. (Abant Izzet Baysal
University) who were 22.71±1.90 average years old participated. While the anaerobic power
values of the subjects were determined by using the Margaria Anaerobic Power Test, agility
performance is measured by Illinois Agility Test. After initial measurements, subjects were
randomly assigned into three groups; (1) creatine, (2) placebo and (3) control. Both the
creatine group and the placebo group were received the same amount (4 x 5= 20gr.) of
creatine and sugar powder supplement respectively. On the hand, the control group did not
received anything.
The statistical analyses of the study included descriptive statistics, Wilcoxson, Krukal-
Wallis and Mann-Whitney U tests. The results of the study indicated that total body weights
of creatine group increased significantly from pre-test ( x =74.62 kg) to post-test ( x =75.15kg)
