Resumo: | The purpose of this work is to review the literature regarding creatine ingestion by athletes and physical activity enthusiasts, discussing its necessity and, if possible, predicting some consequences. In order to achieve this purpose it was necessary to study the relationship between the muscles energetic system and their regulation. It was also proved necessary to investigate the creatine cycle, its endogenous origin, its metabolizing and conversion into creatine-phosphate. A bibliography was used to collect information about the subject. The research lead to the following conclusions: diet supplementation with creatine leads to increased phosphocreatine levels in human muscles. However, new in vivo experiments are most desirable, because it is already known that creatine interferes with the regulation of some metabolic pathways. |

Para alcançar este objetivo, foi necessário estudar as relações entre os sistemas energéticos musculares bem como a sua regulação. Foi preciso, também, avaliar o ciclo da creatina, sua origem endógena, sua metabolização e sua conversão em creatina fosfato. Usamos a metodologia bibliográfica para coletar informações sobre o assunto em questão, utilizando livros e artigos de revistas especializadas. Esta pesquisa nos levou às seguintes conclusões: a suplementação de creatina na dieta leva ao aumento dos níveis de fosfocreatina muscular em humanos, entretanto novos experimentos terão que ser realizados, uma vez que a suplementação com creatina interfere na regulação de vias metabólicas.Department of Physical Education - State University of Maringá (UEM), Maringá-PR, Brazil2008-06-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3762Journal of Physical Education; Vol 12 No 1 (2001); 27-33Journal of Physical Education; Vol. 12 Núm. 1 (2001); 27-33Journal of Physical Education; v. 12 n. 1 (2001); 27-332448-2455reponame:Journal of Physical Education (Maringá)instname:Universidade Estadual de Maringá (UEM)instacron:UEMporhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3762/2592Silva, Emerson Gimenes Bernardo daBracht, Ana Maria Kelmerinfo:eu-repo/semantics/openAccess2023-01-10T15:37:21Zoai:periodicos.uem.br/ojs:article/3762Revistahttp://periodicos.uem.br/ojs/index.php/RevEducFis/indexPUBhttps://old.scielo.br/oai/scielo-oai.php||revdef@uem.br2448-24552448-2455opendoar:2023-01-10T15:37:21Journal of Physical Education (Maringá) - Universidade Estadual de Maringá (UEM)false |
