Believe It or Not !!!

This should make your heart beat faster. you would not have heard this before. Beleive it or not! Rowers have hearts that are among the biggest ever seen in healthy people. Recently i came across this article from US researchers who have a wide opinion about this. Rowers hearts are enormous, elongated, torpedo-shaped heartsw, twice the mass of a normal heart, that drew blood in likee a suction pump and push it out like a piston. The reason is that rowers use all the big muscles of their body, respectivelt contracting and relaxing them which puts a huge demand on the heart to supply those muscles with blood. In fact, rowing puts such strains on the heart that astronauts use rowing machines during space flights to try to maintain therir cardiovascular fitness. Interestingly, a study found that the heart growth increased as the intensity of the training increased.
