The aim of this research was to verify the effect of the creatine supplementation on performance in the 10 and 30-second Wingate tests, besides its influence in the creatinine, urea and lactate concentration and body mass of physically active men. This research selected nine volunteers, who were then separated in two groups using the double-blind procedure: creatine group (n=4) and placebo group (n=5).The supplementation was orally administered during ten days. The creatine group ingested 20g of creatine (4 times a day) in the first five days, followed by an ingestion of 5 g/day until the tenth day. The placebo group received the same dosage, but of maltodextrine instead, as placebo. The test protocol performed before and after the supplementation period consisted of an adapted 10-second Wingate test, followed by an interval of 20 minutes for application of the 30-second Wingate test .Blood samples were collected before and after the supplementation period for analysis of creatinine and urea, lactate at rest, 90 seconds after the 10-second test and 180 seconds after the 30-second test. Creatine supplementation promoted significant raise (p<0.05) in maximal power output during the 30-second test, in the mean power output in the 10 second-test, besides the creatinine concentration. The results suggest that creatine supplementation can improve individual performance in high intensity activities and short duration made in cycle ergometer; however, creatine supplementation increases the creatinine concentration at rest.

“…No entanto, os estudos realizados por BERMON et al (1998), BALSOM et al (1995, COOKE e BARNERS (1997), COOKE et al (1995) e LEDFORD e BRANCH (1999) falharam em demonstrar esse efeito. FRANCAUX e POORTMANS (1999) observaram que tanto o grupo Cr quanto o grupo placebo apresentaram aumento de 6% de força após o período de suplementação (21 gramas de Cr ou placebo/dia, durante sete dias, seguidos de 3 gramas de Cr /dia, durante 58 dias), associado a um treinamento de força.…”

______________________________Ergogenic Nutrition, Fitness, performance and ergogenic supplementation. ______________________________ R E S U M O____________________________________________________________________________ O objetivo desta revisão é expor os potenciais dos suplementos ergogênicos nutricionais dentro da musculação, destacando os aspectos históricos, regulamentação, tipos, efeitos ergogênicos, efeitos adversos, principais fontes, suplementação, aspectos legais e éticos, e os possíveis mecanismos de ação e sua relação com o desempenho físico. A busca foi realizada em livros, artigos de revistas científicas, artigos extraídos via Internet, buscados nos bancos de dados da MEDLINE, LILACS, SCIENCE DIRECT, PERIÓDICOS CAPES, PUBMED e SCIELO. As discussões da presente revisão poderão servir como base de estudo e planejamento das ações estratégicas de treinadores e fisiologias do exercício no que refere ao uso de suplementação ergogênica nutricional na melhoria da performance dentro da musculação. A B S T R A C T ____________________________________________________________________________The purpose of this review is to demonstrate the potential ergogenic nutritional supplements in the bodybuilding, highlighting the historical aspects, regulations, types, ergogenic effects, adverse effects, major sources, supplements, legal and ethical aspects, and possible mechanisms of action and its relation with physical performance. The search was conducted in books, scientific journal articles, articles taken from the Internet, searched in the databases of MEDLINE, LILACS, SCIENCE DIRECT JOURNALS CAPES, PubMed and Scielo. The discussions of these in this review may serve as a basis for study and planning of strategic actions of coaches and exercise physiologists as regards the use of ergogenic nutritional supplementation in improving performance in the gym.. ____________________________________________________________________________ INTRODUÇÃOAo longo de toda a história da humanidade, o ser humano tem preservado o ato da alimentação como algo sagrado. Sabe-se muito sobre o que deve ser uma alimentação saudável e completa, tanto do ponto de vista cientí-fico como popular. Aliás, não há nenhum meio de comunicação que, em algum momento, não tenha abordado a importância de uma dieta, além de, obviamente, sempre ressaltar os modismos. Assim sendo, deve-se sem dúvida alguma valorizar esse aspecto tão fundamental na vida das pessoas (CORREIA, 1996).Atualmente a possível eficiência ergogênica de inú-meros recursos em aprimorar o desempenho físico em diferentes tipos de exercícios físicos tem sido amplamente estudada (THEIN et al, 1995). Nesse sentido, a utilização de alguns suplementos nutricionais com potencial ergogênico tem-se mostrado eficiente por protelar o aparecimento da fadiga e aumentar o poder contrátil do músculo esquelético e/ou cardíaco, otimizando, portanto, a capacidade de realizar trabalho físico, ou seja, o de sempenho físico (APPLEGATE, 1995; CLARKSON, 1996).A nutrição é a soma dos processos de ingestão ...
