How long does it take a young person to lose muscle strength if they go from being moderately active to being a couch potato?
It only takes two weeks, a new study finds.
Researchers from the University of Copenhagen examined what happens to the muscles in younger and older men after a period of high inactivity, by way of immobilization with a leg pad.
“Our experiments reveal that inactivity affects the muscular strength in young and older men equally. Having had one leg immobilized for two weeks, young people lose up to a third of their muscular strength, while older people lose approximately one fourth.
