After a heart attack, patients must create new heart muscle cells to heal. A new study shows that mice make more new heart muscle cells when they exercise compared to when they do not. This was true for both healthy mice and those that had experienced a heart attack. Findings demonstrate that one reason exercise is beneficial to health is that it increases the heart's capacity to regenerate.
