Overdoing your training for an endurance sport can leave you mentally fatigued.  A French investigation, just published in the journal Current Biology, studied 37 thirty something male athletes during a 9 week training program.

 

Over-training led to feelings of mental exhaustion but also increased impulsivity with a preference for immediate rather than gratification.  Brain imaging tests confirmed that the altered decision-making was due to diminished prefrontal cortical activation.

 

This study once again emphasizes that our bodies work best when we moderate our activities.  If you are forced to overindulge, know that you shouldn’t be making any momentous decisions afterwards.
