In a new study, researchers found that the quicker someone completes the long-distance cross-country ski race Vasaloppet, the lower the risk of them developing high blood pressure.
The research was conducted by a team at Uppsala University.
High blood pressure counts among the greatest risk factors for heart disease and premature death.
Previously, the researchers had compared the health of 206,889 Vasaloppet competitors with that of 505,542 individuals from the general population over several years.
They focused on parameters such as the risk of heart attack, stroke, and depression.
They found that, in each of these, the cross-country skiers enjoy better health than the population at large.
In this new study, researchers tested whether the risk of high blood pressure is affected by competing in long-distance races such as Vasaloppet.
They found that the skiers had a 41% lower overall risk of developing high blood pressure than the general population.
This implies that endurance training has beneficial effects for those seeking to reduce the risk of high blood pressure and may partly explain what has previously been seen: Vasaloppet skiers run a reduced risk of heart attack and premature death.
There is a very strong link between the time in which a competitor completes Vasaloppet and their risk of high blood pressure.
The fastest 20% of skiers had a 61% lower risk of developing high blood pressure compared to the general population. The slowest 20% of skiers had a 26% lower risk, which is still a major reduction.
It appears that the more highly intensive the training people do, the better it is for their arteries.
The study also showed that the number of races competed in was less important to the risk of high blood pressure, something that can be interpreted as meaning that high-intensity training itself has a beneficial effect on blood vessels.
The study proposes that a high level of training leads to a much lower risk of high blood pressure.
The lead author of the study is Kasper Andersen, a researcher at Uppsala University’s Department of Medical Sciences and cardiologist at Uppsala University Hospital.
The study is published in the online scientific journal Circulation.
