Running a marathon can affect your heart— published: 10-26-2010
Businessweek.com is reporting on a new study that suggests that running a marathon can damage your heart, with more than half of the segments in the heart's main pumping chamber typically functioning a little under par during the race. The good news is that other parts of the heart pick up the slack and the changes reverse within three months or fewer after the run, the researchers found.
The end result is that the study shows that the more fit and trained a runner is, the less effect the strain of a marathon was found to have on the heart.
