Venice, Italy – May 3, 2019: According to a study presented today at the EuroCMR 2019, a scientific congress of the European Society of Cardiology (ESC), the training and the completion of. a marathon "reverse" the aging of the main blood vessels.1 The study found that older and slower riders benefit the most.
The author of the study, Dr. Anish Bhuva, a Fellow of the British Heart Foundation at University College London, said: "Novice riders trained for six months and having completed their first marathon have experienced a four-year reduction in arterial age and a decrease of 4 mmHg in systolic blood.This is comparable to the effect of drugs and, if maintained, results in a reduction of about 10 % of the risk of stroke during life. "
A hallmark of normal aging is the rigidity of the blood vessels, which increases the risk of stroke and heart disease even in healthy people. Compared to their peers, lifelong athletes have biologically younger blood vessels. This study examined whether training for a marathon could alter aortic stiffness even in novice runners.
The study included 139 healthy beginner runners, aged 21 to 69, who had been invited to a training program for the first time and were running approximately 10 to 20 km per week for six months before completing the training. London Marathon 2016 or 2017.2.3
Before starting training and two weeks after the end of the marathon, participants were required to undergo magnetic resonance imaging (MRI) and heart and blood vessel ultrasound, a fitness test, and blood pressure and blood pressure measurements. heartbeat. The biological age of the aorta was calculated at both times.
Once the marathon ended, the aortic stiffness had decreased and the aorta was four years younger than before training. Older participants and those with longer marathon arrival times had a greater reduction in aortic stiffness after training. The reductions in aortic stiffness were independent of changes in blood pressure.
Dr. Bhuva said, "It's not necessary to be an elite athlete to enjoy the benefits of the marathon race.In fact, the benefits have become more important to those who were Older and Slower By completing the training and reaching the finish line, rejuvenate the cardiovascular system of the first marathon runners. "
Fitness improved and heart rate dropped after training, both weakly. "The minimal impact on these conventional markers of health suggests that study participants were trained in their personal boundaries," said Dr. Bhuva. "Aortic stiffness and blood pressure have changed more than fitness and heart rate."
Dr. Bhuva noted that participants had been running less than two hours per week prior to marathon training and that their arrival times were slower than the average, which was expected as it was their first race. "The study shows that the health benefits of lifelong exercise begin to appear after a relatively short training program," he said. "Training for a marathon can be a good motivator to stay active, and many people take advantage of it and keep running, which should increase the chances of sustaining profits."
Professor Sanjay Sharma, medical director of the London Marathon and author of the study, said: "The benefits of exercise on the heart and circulation are well established and are badociated with a decline in cardiovascular disease and mortality Recent studies have shown that exercise can delay the aging of the cardiovascular system.Our study shows that a marathon for the first time makes the cardiovascular system "younger", allowing participants to benefit from these benefits while running for the good cause.
