Resumo
A fadiga mental (FM) é causada por uma atividade de alta demanda cognitiva realizada por longos períodos, e tem potencial para prejudicar a performance humana. Postula-se que uma das causas da FM é o baixo status energético neuronal que aumentaria a percepção subjetiva de esforço, sensação de fadiga e desengajamento do exercício. O objetivo do estudo é verificar se a suplementação com lactato de cálcio é capaz de diminuir a FM, e consequentemente manter a performance dos atletas de futsal. Diante disso, a amostra consistiu em 6 jogadores de futsal, que executaram um protocolo específico para indicar o desempenho do passe nas condições: 1) controle (sem FM); 2) FM; 3) FM e placebo; 4) FM e lactato, de forma randomizada, duplo-cega e contrabalanceada. A hipótese era a de que a administração de lactato de cálcio fosse capaz de reverter ou atenuar a FM, mantendo o desempenho do passe quando comparados ao controle.
Mental fatigue (MF) is caused by a high cognitive demand activity performed for long periods, and has the potential to impair human performance. It is postulated that one of the causes of MF is the low neuronal energy status, which would increase the subjective perception of exertion, the feeling of fatigue and the disengagement from the exercise. The aim of the study is to verify whether calcium lactate supplementation is able to decrease MF, and consequently to maintain the performance of futsal athletes. Therefore, the sample cosisted in 6 futsal players, who performed a specific protocol to indicate the performance of the pass under the conditions: 1) control (without MF); 2) MF; 3) MF and placebo; 4) MF and lactate, in a randomized, double-blind and counterbalanced way. The hypothesis was that the administration of calcium lactate was able to reverse or attenuate MF, thus maintaining the accuracy of the pass when compared to it’s control.
