简要总结
The purpose of this project is to provide further insights into the neurophysiology behind the MF-induced impairment in endurance performance. The aim is to perform a randomized controlled trial in which we partly replicate studies of Marcora et al. (2009) and Bigliassi et al. (2017), while extensively monitoring brain activity during the entire protocol (i.e. both cognitive and physical tasks) by using EEG.

研究组 & 干预措施
Mental Fatigue (Stroop) - Chair task
Participants will be performing the Chair Task (150 submaximal dynamic knee extensions at 50% of their maximal voluntary contraction (MVC)) when mentally fatigued. A 60 minute variant of the Stroop task will be used to induce the mental fatigue. During the whole trial EEG will be measured.
干预措施: Mental Fatigue (Stroop task) (Other)
Control Task (Documentary) - Chair Task
In the control task subjects will have to watch a documentary on the same computer screen as that used for the experimental trial. These documentaries are chosen based on their emotionally neutral, yet engaging content. This will be followed by the Chair Task, During the whole trial EEG will be measured.
干预措施: Control (Documentary) (Other)
Mental Fatigue (Stroop) - Bike Task
Participants will be performing the Bike Task (a 9 min cycling task performed at 45 rpm with intensity being constant and will be 10% below VT) when mentally fatigued. A 60 minute variant of the Stroop task will be used to induce the mental fatigue. During the whole trial EEG will be measured.
