A new study suggests that walking at a brisk pace may significantly reduce the risk of developing heart rhythm problems, such as atrial fibrillation. The research, led by Dr. Jill Pell of the University of Glasgow, highlights walking as an easy, cost-free way to support heart health.
"Walking doesn’t require a gym membership or special equipment—just step outside and go,” Dr. Pell told CNN. "While treatments for heart rhythm issues are available, prevention is always better.”
### **Key Findings**
Researchers analyzed data from the UK Biobank study, which began in the early 2000s. Participants self-reported their walking pace as **slow, average, or brisk**. The results showed:
- **6.5%** walked slowly
- **53%** at an average pace
- **41%** at a brisk pace
Compared to slow walkers, those with an **average pace** had a **35% lower risk** of heart rhythm disorders, while **brisk walkers** saw a **43% reduction** in risk.
### **Even Short Walks Make a Difference**
In a smaller group of **82,000 participants** who wore activity trackers, researchers found that just **5–15 minutes of moderate-paced walking (3–4 mph) per day** was enough to significantly lower the likelihood of heart rhythm issues.
### **Stronger Benefits for Women and Younger Adults**
The protective effects were most pronounced in **adults under 60** and particularly in **women**. Dr. Pell noted that while women are generally less prone to atrial fibrillation than men, they face higher risks of complications like stroke if it develops.
### **Study Limitations and Next Steps**
The research had some limitations—for example, people with undiagnosed health conditions might naturally walk slower. To account for this, the study excluded participants with known cardiovascular issues at the outset.
Dr. Pell emphasized the need for further research, including **intervention studies** where slower walkers are encouraged to increase their pace to confirm the findings.
**The Bottom Line:** Walking at a brisk pace—even for just a few minutes a day—could be a simple, effective way to protect your heart.
