UF:  Study shows why exercise magnifies exhaustion for chronic fatigue syndrome patients

The mechanism that causes high-performance athletes to “feel the burn” turns out to be the culprit in what makes people with chronic fatigue syndrome feel exhausted by the most common daily activities, new University of Florida Health research shows.

Published in the February issue of the journal Pain, the study shows that the neural pathways that transmit feelings of fatigue to the brain might be to blame. In those with chronic fatigue syndrome, the pathways do their job too well.

The findings also provide evidence for the first time that peripheral tissues such as muscles contribute to feelings of fatigue. Determining the origins of fatigue could help researchers develop therapies or identify targets for those therapies.
