MONTREAL – The people in health who train and complete a first marathon subtract the equivalent of four years of age-vascular, according to a new british study published by the Journal of the American College of Cardiology.

The researchers from University College London have linked this practice to a reduction of the blood pressure and the stiffness of the aorta. The benefits of the most marked have been noted in male runners older and slower, the blood pressure was highest at the start.

The hardening of the arteries is a normal consequence of aging, but it also increases the risk of a cardiovascular event in individuals otherwise healthy.

The researchers recruited 138 healthy persons who have participated in a first marathon in London in 2016 and 2017. These participants were examined six months before and within three weeks of the race, in order to determine if their training had reduced the stiffness of their arteries.

The subjects did not face more than two hours per week at the start of the study. They had on average 37 years old and 49 percent of them were men. Many have adopted the training suggested by the organizers of the marathon to those who are in a first experiment, which is about three races per week, which increase in intensity over a period of 17 weeks.

Training lowered systolic and diastolic blood pressure of participants of 4 and 3 mmHg, respectively. The stiffness-general of the arteries was decreased, but the beneficial impact the most important has been measured on the aorta distal, in which the elasticity has increased by 9 percent. This corresponds to a reduction of approximately four years of age the arteries.

The authors of the study believe that their work demonstrates that it is possible, with only six months of training, to reverse the consequences of aging on the blood vessels.

Even if researchers have not recruited as participants in health, they believe that people with high blood pressure or whose arteries are more rigid and could further improve their cardiovascular health training.
