Muscle Fatigue

Nasa Funded Research on Muscle Fatigue

Micheal Reid of the University of Kentucky has been researching N-acetycystiene (NAC) and its effect on limiting free radicals. NAC is used for the liver during a drug overdose because it eliminates free radicals. Free radicals are also made during strenuous muscle activity. Astronaut's huge suits make 6-8 hours of activity seem like a marathon. If NAC can help eliminate the free radicals made, the astronauts could have longer periods of muscle activity without the fatigue. This is very important for astronauts who are involved in deep-space exploration, like a trip to Mars.
