Scientists uncovered a previously unknown repair mechanism of muscles that kicks in within 5 hours after the exercise. The control centers of muscle cells — called nuclei — scoot toward these tiny injuries to help patch them up.

In this study scientists studied muscle fibers (thin elongated tubular cells of skeletal muscles) of mice and people.

In the future, medical treatments could potentially be devised to target the molecular pathways that allow the nuclei to migrate and start this repair process.
