Resumen

Introdução: A creatina tem sido considerada agente ergogênico para indivíduos onívoros e vegetarianos, porém, nota-se lacuna importante sobre o efeito dessa suplementação sobre a performance de veganos, grupo que apresenta maiores restrições nutricionais dentre os vegetarianos. Objetivo: Analisar o efeito da suplementação de creatina sobre performance em teste de força e composição corporal de veganas. Métodos: Quatorze veganas não-atletas foram randomicamente distribuídas em grupo creatina (n = 7) e placebo (n = 7). Antes e depois da suplementação (0,3 g kg-1 d-1 por 7 dias) foram realizados testes de performance em leg press (3 séries de repetições máximas até falha, a 80% de uma repetição máxima, 60 segundos de intervalo), e antropometria. Resultados: Após suplementação, houve diferenças significativa no número de repetições na primeira série e no somatório das três séries para ambos grupos, porém, com o o tamanho do efeito (effect size) e delta percentual superiores para grupo creatina. Na segunda série, não houve diferenças significativas entre grupos e momentos, porém, effect size e delta percentual também foram superiores para grupo creatina. Não foi observada alteração significativa na composição corporal. Conclusão: A suplementação de creatina apresentou maior efeito sobre performance em teste de força para membros inferiores, quando comparadas ao placebo, sem alterar composição corporal.
