The Role of the Brain in Mental and Physical Fatigue

The goal of this clinical trial is to determine the role of brain neurotransmission in the onset of fatigue, identify the brain areas involved, and determine how brain activity and neuromuscular efficiency changes during onset of fatigue. Three different experimental studies (physical fatigue, mental fatigue and combined) will be performed with a randomized, single-blinded, placebo controlled, counter-balanced, cross-over design. The objectives of the projects are as follows: * To experimentally assess the role of a dopamine, and a noradrenalin reuptake inhibitor in the onset of exercise-induced fatigue * To identify changes in brain activation associated with altered PF and fatigue perception * To experimentally assess the effect of a NA or DA reuptake inhibitor on MF, brain activation and the sources of changes in brain activation * To experimentally assess the role of brain neurotransmitters (DA, NA) in the interaction between mental and PF from a neurophysiological perspective. Participants will be healthy young adults. In each study, they will start with a familiarization trial followed by two experimental trials and one control trial with a randomized treatment order. At each visit, different drugs will be administered to elicit different neurotransmitter response. The trials will be performed at the MFYS exercise lab (BLITS, VUB campus Etterbeek, Boulevard General Jaques 271, 1050 Elsene (Brussels)). Depending on the type of study they are participating in, partici…
