New research suggests that just one hour of moderate exercise per week can help reduce the risk of developing atrial fibrillation (AFib). The study, which utilized data from thousands of individuals wearing fitness trackers, found that even a modest amount of physical activity can have a protective effect against AFib. However, those who engaged in more exercise experienced even greater benefits.
The study, which is the largest of its kind, used data from the All of Us Research Program led by the National Institute of Health. The program includes health, genetic, and lifestyle data from a diverse group of individuals in the United States, including historically underrepresented populations. More than 6,000 individuals were included in the study, with participants predominantly being white and female.
Researchers found that each hour of physical activity per week reduced the risk of AFib by 11%. The protective benefits of exercise increased with higher levels of physical activity, with those who exercised more experiencing a greater reduction in risk. The study also found that exercise levels were inversely associated with AFib risk, with individuals who engaged in more physical activity experiencing a lower risk of developing the condition.
While some studies have suggested that excessive exercise may be a risk factor for AFib, doctors emphasize that the health risks of a sedentary lifestyle far outweigh any potential risks of excessive physical activity. Overall, the research supports current guidelines that recommend moderate levels of exercise as an important component of cardiovascular disease prevention, including AFib.
In conclusion, the study provides valuable insights into the relationship between exercise and AFib risk. By incorporating more physical activity into their daily lives, individuals can not only reduce their risk of developing AFib but also lower their risk of other cardiovascular diseases as well.
