Studies have been done that show even just a single workout is healthy for the heart. A fascinating new study on mice shows that just 30 minutes on the treadmill affects activity within the cardiac cells greatly. People who exercise regularly are much less likely to develop cardiac disease or to die from cardiac related issue.

Researchers have found that telomeres are tiny caps on the end of chromosomes, which prevent fraying, or damage to our DNA. As people get older, these cells get shorter and shorter. Aerobic exercise affects telomeres, and people who exercise regularly have longer telomeres.

A study form Maryland used mice running on treadmills for 30 minutes a day at moderate intensity. The scientists looked for subtle changes in the Mice’s cardiac cells, and it turned out that after each 30 minute run, the cells were noticeably different than the mice that weren’t running.

A single moderate workout can be beneficial to someone’s heart. This emphasizes the important of exercising regularly to keep a healthy heart.
