Astronaut muscles waste away on long space flights reducing their capacity for physical work by more than 40%, according to research published online in the Journal of Physiology.
This is the equivalent of a 30- to 50-year-old crew member's muscles deteriorating to that of an 80-year-old. The destructive effects of extended weightlessness to skeletal muscle -- despite in-flight exercise -- pose a significant safety risk for future human missions to Mars and elsewhere in the Universe.
