Resumo: Several researches on creatine have been done due to its potential effects on the physical performance of athletes involved in high intensity, short duration and intermittent exercises with short periods of recovery. Phosphorylated creatine is an energy reserve in the muscle cells. During an intense exercise, its breakdown liberates energy used to regenerate adenosine triphosphate. Approximately 95% of the creatine pool is found in the skeletal muscle, and the regenerating process after exercise is oxygen dependent. Studies show that supplementation with this compound may procedure an increase of 10% to 20% in the organic pool, and this percentage is higher in vegetarian athletes (up to 60%). There is still controversy regarding the benefits and risks of supplementation with this substance. This paper reviews some aspects related to the creatine metabolism and its use as an ergogenic substance in sports practice.

A creatina fosforilada é uma reserva de energia nas células musculares. Durante um exercício intenso, a sua quebra libera energia é usada para regenerar o trifosfato de adenosina. Aproximadamente 95% do pool de creatina encontra-se na musculatura esquelética e sua regeneração após o exercício é um processo dependente de oxigênio. Estudos mostram que a suplementação com este composto pode aumentar o pool orgânico em 10 a 20%, e este percentual é maior em atletas vegetarianos (até 60%). Ainda existe controvérsia com relação aos benefícios e riscos da suplementação com esta substância. Este estudo revisa alguns dos aspectos relacionados com o metabolismo da creatina e seu uso como substância ergogênica na prática desportiva.Núcleo de Editoração – PUC-Campinas2002-04-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9065Brazilian Journal of Nutrition; Vol. 15 No. 1 (2002): Revista de NutriçãoRevista de Nutrição; Vol. 15 Núm. 1 (2002): Revista de NutriçãoRevista de Nutrição; v. 15 n. 1 (2002): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPporhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9065/6459Copyright (c) 2023 José PERALTA, Olga Maria Silverio AMANCIOhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPERALTA, José Silverio AMANCIO, Olga Maria 2024-04-08T13:38:01Zoai:ojs.periodicos.puc-campinas.edu.br:article/9065Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2024-04-08T13:38:01Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false
