The cardiovascular benefits of exercise are unlimited
There is no limit to the cardiovascular benefits of exercise, according to a new study published by PLOS. The researchers found that people who are the most active have the lowest risk of cardiovascular disease.
While the link between exercise and reduced cardiovascular risk was previously established, the extent of these benefits remained unclear.
A team led by Terence Dwyer of University of Oxford set out to investigate by analyzing data from 90,211 UK Biobank participants who did not have cardiovascular disease. The individuals had worn activity trackers over a 7-day period from 2013 through 2015.
During five years of follow-up, 3,617 of the participants were diagnosed with cardiovascular disease. The more physically active the individuals were, the less likely they were to develop cardiovascular issues. For example, those who exercised the least were about 54 percent more likely to be diagnosed with cardiovascular disease compared to the most active people.
Participants in the lowest category of physical activity, who also smoked more and had higher body mass index, were most often diagnosed with hypertension.
“This is the largest ever study of exquisite device-measured physical activity and cardiovascular disease. It shows that physical activity is probably even more important for the prevention of cardiovascular disease than we previously thought,” said Professor Aiden Doherty.
“Our findings lend further weight to the new WHO guidelines on physical activity which recommend at least 150 to 300 minutes of moderate to vigorous aerobic activity per week for all adults.”
According to Professor Dwyer, the results of the study reaffirms that physical activity is an important way of preventing cardiovascular disease.
“The potential risk reduction estimated in those engaging in relatively high levels of activity is substantial and justifies a greater emphasis on measures to increase levels of physical activity in the community.”
The study is published in the journal PLOS Medicine.
