Walking at a brisk pace may reduce the risk of heart rhythm problems. A recent study published in BMJ Heart analyzed data from over 420,000 UK participants who reported their walking speeds. The researchers found that those who walked faster had lower risks of atrial fibrillation and ventricular arrhythmias.
The study defined slow, average, and brisk paces as less than 3mph, 3-4mph, and more than 4mph, respectively. Tracking the participants for 13 years showed that those with a brisk pace were 43% less likely to develop heart rhythm abnormalities compared to those with a slow pace.
The study also found that walking at an average or brisk pace was associated with lower risks of atrial fibrillation and ventricular arrhythmias. However, the association between walking speed and heart rhythm problems was partially influenced by metabolic and inflammatory factors.
Demographic and lifestyle factors accounted for in the study included age, sex, socioeconomic status, and health habits. The researchers noted that the study’s limitations included its observational design and lack of diversity among participants.
Despite these limitations, the study suggests that brisk walking may play a role in reducing heart rhythm problems. Lead researcher Prof Jill Pell said that faster walking can decrease the risk of obesity and inflammation, which in turn reduces the risk of arrhythmias.
