United States: A recent study has revealed that walking at a brisk pace significantly lowers the chances of developing heart rhythm abnormalities. Individuals walking faster than 4 miles per hour reduced their risk by 43% compared to those walking under 3 mph, according to Heart journal.
Researchers also noted that duration of walking combined with a moderate or fast pace helped reduce heart rhythm issues by 27%, as reported by HealthDay.
Why Speed and Time Matter
“These findings reinforce the importance of encouraging a faster walking pace in physical activity guidelines,” said Dr. Jill Pell, chair of public health at the University of Glasgow.
She added that brisk walking may help prevent cardiac arrhythmias, a common and sometimes serious heart rhythm disorder.
Large-Scale Data Backs It Up
The findings come from the UK Biobank, a major health study involving over 421,000 participants, including 82,000 who wore accelerometers to track walking pace.
- Brisk walkers (41%) saw the greatest benefits
- Moderate-paced walkers (53%) also saw improvements
- Slow walkers (<6%) faced higher risks
Results showed a 43% reduction in heart rhythm issues among brisk walkers, and a 35% drop among moderate walkers.
Reduced Risk of Atrial Fibrillation
The study also highlighted a drop in atrial fibrillation (AFib)—a heart condition linked to stroke:
- Brisk walkers had a 46% lower risk of AFib
- Average-paced walkers saw a 38% reduction
These benefits are believed to be driven largely by inflammation and metabolic improvements, which accounted for 36% of the lowered risk.
The Science Behind It
Prior studies have long suggested brisk walking helps prevent obesity, regulate blood sugar, and reduce blood pressure. This new research adds to that evidence, showing how these factors may directly impact heart rhythm stability, as reported by HealthDay.
“Walking faster decreased the risk of obesity and inflammation, which, in turn, reduced the risk of arrhythmia,” the researchers wrote.
