According to new research, muscle fatigue may originate in your head.
You know how some workouts are better than others? How one day you feel great at the gym and the next day you're totally pooped? The answer may lie in the brain. According to new research, muscle fatigue may originate in your head.
In what is the first study to look at the interaction between the brain and muscle fatigue, researchers from the University of Zurich discovered a mechanism in the brain that triggers your muscles to reduce their performance. Published in the European Journal of Neuroscience, researchers believe that the brain helps to make sure that one's own physiological limits are not exceeded, according to ScienceDaily.
By looking at nerve impulses from the muscle, functional magnetic resonance imaging of the brain and in tests using a bicycle, researchers found that the brain plays a role in brain fatigue. Based on the new information, scientists hope to develop strategies to optimize muscle performance and help people who feel fatigued or tired, such as those with chronic fatigue.
So the next time you're having a tough time with a workout, just remember that it's just your brain trying to keep you safe and healthy!
