Acute Effects of Different Creatine Supplementation Methods on Anaerobic Performance

Abstract

The aim of this study is to compare the acute effects of different creatine loading methods on anaerobic performance in soccer players. Totally 21 healthy male soccer players participated in this study. The study was conducted in a randomized and double-blind study design. Athletes were loaded with creatine on 3 different days. The different creatine supplementation methods were as follows; athletes took creatine supplement 4 times a day for 15 days, 4x5 grams for the first 5 days and 5 g for the following 10 days. In other creatin loading is took 0.3 grams of creatine per kg for 15 days. In other creatin loading is (placebo loading) received the same amount (Maltodextrine) for 15 days. Vertical jump, 10-30 m sprint test and agility test were performed on all subjects. The Shapiro-Wilk test was used for normality distribution of the data. Since parametric test assumptions were met, t-test for dependent groups and one-way analysis of variance test (ANOVA) for repeated measurements were used to compare dependent group differences. Significant differences were found for 10-30 m sprint, vertical jumping, zig zag test (p
