A new study, carried out by researchers from Hôpital de la Pitié-Salpêtrière in Paris, France, finds that too much exercising may affect the brain, in particular, reduce the capacity to make decisions.
For the study, the scientists recruited 37 competitive male endurance athletes whose average age was 35 years. For the study purposes, one group of participants continued their regular regimen, and another group increased their training by 40% per session over a period of 3 weeks.
After 3 weeks, the researchers tested the economic choices of all athletes found that overloaded athletes were more likely to make their choices more impulsively.
The corresponding author Mathias Pessiglione comments: “This brain region, therefore, appeared as the weak spot of the brain network responsible for cognitive control. You need to control the automatic process that makes you stop when muscles or joint hurts.”
