- ItemSomente MetadadadosCafeína reduz a percepção de esforço e melhora o desempenho físico(Universidade Federal de São Paulo (UNIFESP), 2014-03-26) Motoyama, Yuri Lopes [UNIFESP]; Azevedo, Paulo Henrique Silva Marques de [UNIFESP]; http://lattes.cnpq.br/6559911217770194; Universidade Federal de São Paulo (UNIFESP)In this study, we showed that supplementation of caffeine increases exercise time associated with a reduction in perceived exertion scale (PES) and increased activation of the motor drive. Nine cyclists performed two tests of constant workload using caffeine and placebo on different days. In both conditions was not identified the fatigue from the motor drive activity, concluding that fatigue is controlled by central mechanisms.
