serotonin: an accelerator but also a brake

“the neurotransmitter serotonin is released when you exercise, and indeed, it helps us to keep going”

“the substance plays a role in relation to the fact that we also feel so exhausted we have to stop”

“a surplus of serotonin triggers a braking mechanism in the brain”

“serotonin functions as an accelerator but also as a brake when the strain becomes excessive”

“Central fatigue is a sort of tiredness which, instead of affecting the muscles, hits the brain and nervous system”

“the brain sends insufficient signals to the muscles to keep going, which in turn means that we are unable to keep performing”

“The brain communicates with our muscles using so-called motoneurons”
