Exercise such as jogging casually ran very good for the heart and blood vessels. But not so with more severe exercise, like marathon.
According to experts from Greece, the blood vessels of the marathon runners are even more potential to be rigid so that blood flow becomes smooth. Known heavy exercise is bad for the heart because it causes hardening of the arteries, increasing blood pressure, heart attacks, even death.
"If you do not exercise, your risk of cardiovascular disease would be high, just as when you exercise too much," said lead researcher Dr.Despina Kardara of Athens Medical School. He added that the cardiovascular system is like a sports car engine. When not in use, for long would be damaged. But if the car was too "digeber", can be the engine burn.
In this study Kardara and his team studied the health of 49 male marathon runners and 46 people who were not athletes as the control group. It turned out that the marathon runners have significantly systolic blood pressure (the pressure above) is higher than non-athletes marathon.
The researchers concluded that vigorous exercise increases the risk of blood vessel kekakukan. "Stiff arteries will cause high blood pressure and can damage the heart function. In general, aortic stiffness is an indicator of cardiovascular disease and hardening of the arteries," said Kardara.
There are many reasons for the occurrence of arterial stiffness in marathon athletes. One of them is too extreme sport that will cause excessive stress on artery walls, causing arteries to work too hard. Dr.Charalombos according Vlachopoulos, one of the researchers.
"The endurance athlete should be noted the number and volume of their training programs. Let them accompanied by a doctor, especially before intense exercise such as running a marathon," said Kardara.
