the physical activity not just associated with one lower risk of cardiovascular diseaseBut there is no threshold for this association, with the lowest risk of cardiovascular disease observed for those who are more active, according to a new study published this week in ‘PLOS Medicine’ by Terence Dwyer, of the University of ‘Oxford, UK, and colleagues.
Research has shown that there is one inverse association between self-reported physical activity and the onset of cardiovascular disease. However, there is uncertainty about the range of this association, especially at higher levels of physical activity.
In the new study, researchers used data from 90,211 UK Biobank participants without prior cardiovascular disease who accepted use an accelerometer to measure your physical activity for a period of 7 days between 2013 and 2015.
Participants in the lower category of physical activity smoked more, Had a higher body mass index and C-reactive protein, and were more often diagnosed with hypertension. Overall, 3,617 cases of cardiovascular disease were diagnosed in participants during an average of 5.2 years of follow-up.
People in each growing quartile of physical activity, for moderate-intensity activity, vigorous-intensity activity, and total physical activity, had less likely to have cardiovascular disease.
For example, compared with those in the lower quartile, those in the second quartile of moderate-intensity exercise had a 71% chance of being diagnosed with cardiovascular disease, those in the third quartile had a 59% chance of and those in the highest quartile had a 46% probability.
Associate Professor Aiden Doherty, of the Nuffield Department of Public Health, Oxford University, and one of the lead authors of the study, points out that “this is the largest study ever conducted on physical activity and cardiovascular disease exquisite measurements with devices. It shows that physical activity is probably even more important for the prevention of cardiovascular disease than we thought before. “
“Our findings give more weight to the new WHO guidelines on physical activity that recommend at least 150 to 300 minutes of moderate to vigorous aerobic activity per week for all adults,” he says.
Professor Terry Dwyer, of the Nuffield Department of Reproductive Health and Women’s University at Oxford and lead author of the study, adds that “the results of this study improve confidence that the activity is likely to physics be one important way to prevent disease cardiovascular. The estimated potential risk reduction in those who perform relatively high levels of activity is substantial and justifies a greater emphasis on measures to increase levels of physical activity in the community. “
For her part, Dr Rema Ramakrishnan, of the Nuffield Department of Reproductive and Women’s Health, Oxford University, and first author of this study, notes: “We are confident in the findings of the study because the ‘Physical activity was assessed objectively using a more valid tool that can capture the frequency, intensity, and duration of physical activity rather than self-reported by participants.’
