Scientists have identified the cell mechanism behind the response of muscles to exercise, an advance they say could lead to new strategies for boosting muscle function during aging.
The research, published recently in the journal PNAS, also points to an anti-aging intervention that could delay muscle declines that occur with aging.
“Our data identify an essential mediator of exercise responsiveness and an entry point for interventions to maintain muscle function during aging,” study co-author Keith Blackwell said in a statement.
In the study, researchers found a mechanism behind the fragmentation and repair of the mitochondria – the specialized structures, or organelles, inside every cell responsible for producing energy.
Previous studies have shown that the function of the mitochondria is critical to health.
Research has shown that the disruption of the cycle of repairing dysfunctional mitochondria and restoring the connectivity among the organelles is linked to the development and progression of age-related...
