History
The athlete's heart was first described in 1899 by S. Henschen. He compared the heart size of cross-country skiers to those who lived sedentary lives. He noticed that those who participated in competitive sports displayed symptoms of athlete’s heart syndrome. Henschen believed the symptoms were a normal adjustment to exercise, and felt there was no need for concern. Henschen believed that the entire heart became enlarged, when in fact it is only the left side that becomes hypertrophic. He also believed athletes with AHS lived shorter lives than those who did not acquire the syndrome. Because his research occurred throughout the 19th century, technology was limited, and it became difficult to come up with appropriate ways to measure the hearts of athletes. Few believed in Henschen’s theory about athletes having larger hearts than those who did not participate in sports. Today, Henschen’s original theory has proved to be correct.

Famous quotes containing the word history:
“In nature, all is useful, all is beautiful. It is therefore beautiful, because it is alive, moving, reproductive; it is therefore useful, because it is symmetrical and fair. Beauty will not come at the call of a legislature, nor will it repeat in England or America its history in Greece. It will come, as always, unannounced, and spring up between the feet of brave and earnest men.”
—Ralph Waldo Emerson (1803–1882)
“In front of these sinister facts, the first lesson of history is the good of evil. Good is a good doctor, but Bad is sometimes a better.”
—Ralph Waldo Emerson (1803–1882)
“We don’t know when our name came into being or how some distant ancestor acquired it. We don’t understand our name at all, we don’t know its history and yet we bear it with exalted fidelity, we merge with it, we like it, we are ridiculously proud of it as if we had thought it up ourselves in a moment of brilliant inspiration.”
—Milan Kundera (b. 1929)
