In today's health matters, losing muscle strength as we age may eventually be a thing of the past, thanks to researchers at Columbia University.
Scientists there believe they've discovered why we lose muscle strength as we age and also identified a drug that may help reverse it.
Our muscles start to weaken at around 40 years old and it accelerates after we turn 75. Exercise can help counter these effects. However there are no established treatments.
The team studied mice and found muscle weakness occurs when calcium leaks from a group of proteins in the muscle cells. Study authors say there is a drug going through trials now for heart failure that might help stop those leaks from happening in humans, and ultimately preserve muscle strength.
Findings appear in the journal 'cell metabolism.'
