The number of steps taken and walking speed are two key factors influencing the effectiveness of the most basic form of physical activity: walking. The health benefits of movement, in general, are well-established. Current research focuses on details and variations on this theme, providing increasingly precise guidance. The European Society of Cardiology (ESC) has recently offered parameters based on research and data analysis.
Taking more steps, even below the often-cited goal of 10,000, and walking at a faster pace can significantly reduce the risk of heart problems and cardiovascular diseases in individuals with high blood pressure. This conclusion stems from an analysis of data from over 36,000 people with hypertension, as published in the European Journal of Preventive Cardiology.
The study involved individuals diagnosed with hypertension, with an average age of 64, who were followed for nearly eight years. During this period, 1,935 cases of cardiac issues or stroke were recorded.
Professor Emmanuel Stamatakis, Director of the Mackenzie Wearables Research Hub at the University of Sydney, Australia, supervised the study. “This is one of the first studies to demonstrate a dose-response relationship between daily step count and major problems of the heart and blood vessels,” Professor Stamatakis stated. “we found that if you have high blood pressure, the more you walk, and the greater the intensity, the lower your risk of future serious cardiovascular events.”
The Study
The research establishes a baseline of 2,300 daily steps and observes that an additional 1,000 steps has a noticeable effect. Specifically, with each daily increase up to 10,000 steps, the overall risk is reduced by 17%. Each additional 1,000 steps were linked to a 22% reduction in the risk of heart failure, a 9% reduction in the risk of heart attack, and a 24% reduction in the risk of stroke. The risk associated with stroke continued to decrease even beyond the 10,000-step threshold. Notably, walking for 30 minutes at a pace of approximately 80 steps per minute was associated with a 30% reduction in cardiovascular problems overall.
The Results
Researchers obtained similar results when examining data from 37,350 individuals with normal blood pressure. Each increase of 1,000 steps in daily step count led to an average risk reduction of cardiovascular problems, heart failure, myocardial infarction, and stroke of 20.2%, 23.2%, 17.9%, and 24.6%, respectively.
These findings are particularly relevant considering that approximately 1.28 billion people worldwide suffer from hypertension, which increases the risk of heart disease (49%), stroke (62%), and heart failure (a 77-89% increase). The study establishes parameters relating to the amount of physical activity needed to observe a reduction in the risk of these conditions. “The results support the assertion that any level of physical activity provides benefits, even below the target of 10,000 steps,” Professor Stamatakis added.
Separate research, published in in Lancet Public Health, found that individuals who walked 7,000 steps per day had a 25% lower risk of cardiovascular disease and a 47% lower risk of death from all causes compared to those who walked only 2,000 steps per day. While increasing steps to 10,000 led to even better outcomes, the additional gains were relatively modest.
The American Heart Association emphasizes the broad benefits of walking, noting its positive impact on heart and brain health, and its potential to reduce the risk of heart disease, improve sleep, and boost mood. They recommend a brisk pace for at least 150 minutes per week to maximize these benefits.
While observational evidence doesn’t definitively prove that walking *causes* these health benefits, the growing body of research strongly suggests a significant link. For many, walking is a safe, accessible, and low-cost way to improve overall health and reduce cardiovascular risk. It’s a reminder that even small increases in daily activity can have a substantial positive impact, particularly for those managing conditions like high blood pressure.
