Creatina: efeitos fisiológicos e riscos do uso

Abstract

Since the creatine supplement was discovered by the French scientist Michel Eugêneo Chevreu, while analyzing animal tissues, studies have continued, reaching the conclusion that creatine is a source of energy for the human body and that it could be used to improve the physical performance of athletes. Considering this fact, this article aimed to investigate the pharmacological properties, benefits and risks associated with the use of creatine supplementation in humans. In order to obtain the final results of the study, a literature review was carried out in national and foreign articles, in the Google Scholar and Scientific Electronic Library Online (SciELO) databases, between the period of 2012 to 2023. In the search, the following were used: descriptors: creatine, health and physical exercise. The results indicate that when resistance training is associated with the use of creatine supplementation, lean mass gain is scientifically proven (always following certain protocols). It was observed that the group of people who were tested following these protocols using this supplementation, had a significant body mass gain, while the other group that did not use the supplementation, with the same type of strength training, they did not gain lean body mass and lost fat. It was considered a positive point in cancer treatment, when using creatine supplementation suppressing tumor forms, another factor that can be mentioned in the CNS (Central Nervous System), was the improvement of brain conditions, reaching the point of softening conditions of depression, and finally, we can talk about the benefit for the elderly who also use the supplement mentioned here, directly in gaining strength. At the end of the study, it was possible to verify that the result of using creatine supplementation brings more positives than negatives, so we can say that it is effective in gaining muscle strength, among other benefits for the body. We chose this topic because we often asked friends/acquaintances and even professionals in the field what the effects of creatine are on the body and the answers were always very vague.
