Researchers Focused Heavily On The Stiffening Of Arteries During The Study
Before the participants started training, researchers examined them and paid close attention to their aorta, which is the body’s major artery. Once the participants completed the training program and the marathon, the researchers checked the major artery again.
The biggest problem with the aorta is it starts to stiffen during aging. This causes the heart to work harder, so blood can get through the body. In return, your heart starts to become tired and can become enlarged. By the end of the marathon, the stiffness of the aorta improved by 9%.
