Swimming actually improves heart function during exertion, while running stresses it. A study comparing swimmers and runners after a race found runners' hearts showed signs of strain, but swimmers' hearts worked better. That's a fascinating twist. https://s.fitbodyscience.com/e8fTn5
Correlational — new studies may shift this
Links are real but observational — association, not proof of cause.
Swimming may be better for your heart than running, new research suggests.
Other research comparing swimmers and runners found that after a race, runners' hearts showed more signs of stress, while swimmers' hearts actually functioned better. This suggests swimming could offer unique cardiovascular benefits. However, the study mentioned in the post was done on animals, so it's not clear if the same effects apply directly to humans. The human study supports the idea that swimming is heart-friendly, but more research is needed to confirm it's truly superior.
So if you're looking for a heart-healthy workout, swimming seems like a solid choice—maybe even a bit better than running.
