The effect of the acute supplementation of creatine on the strength parameters and body composition of strength training athletes
Abstract
The strength training became a popular and an important component inside of the physical conditioning programs. Alongside the growth of the number of practitioners both for aesthetic purposes, competition or strength, there is a proportional increase of the use of food supplements, among them stands out the creatine, used by athletes that practice weight lifting and prioritize hypertrophy and explosion training. The objective of this work was to analyze the effects of the acute creatine supplementation (20g/dia for 5 days) on the body composition and its influence on bench press performance by strength training athletes. Ten males participated in a program of physical exercises and they were submitted to anthropometrical, strength and nutritional evaluation. There were not significant statistical increases in the variables weight and muscular mass, 2% and 2.4% respectively. In general, the results demonstrated increases in strength, approximately 8%, but the differences could not be considered statically. Some factors might have interfered directly in the results. The short period between the tests and the lack of a control group, for example, may have interfered on the study results. Therefore, we conclude that the acute supplementation of creatine (20g/days for 5 days) does not have significant effects on the body composition and in the execution of 1RM of bench press in strength athletes.
