Short Bursts of Exercise: Big benefits for Heart Health
Table of Contents
New research reveals that even brief bouts of intense activity throughout the day can significantly reduce the risk of cardiovascular disease, especially for women. This groundbreaking study, published in the British Journal of Sports Medicine, challenges customary exercise guidelines and offers a more attainable approach to improving heart health.
The study, involving over 81,000 middle-aged participants from the UK Biobank, tracked activity levels using fitness trackers worn for seven consecutive days. Researchers focused on “Vigorous Intensity of Daily Living Physical Activity” (VILPA), encompassing short bursts of intense effort like running for the bus or carrying heavy groceries.
For women, the results were striking. Those averaging 3.4 minutes of VILPA daily saw a 45% reduction in major cardiovascular events, a 51% decrease in heart attacks, and a remarkable 67% reduction in heart failure risk.Even shorter durations showed benefits: 1.2 to 1.6 minutes of VILPA daily lowered the risk of major cardiovascular events by 30%, heart attacks by 33%, and heart failure by 40%.
While men also experienced benefits, the effects were less pronounced. Professor Scott Lear of Simon Fraser University, a key researcher on the study, explained, “With accelerometers, you can watch things like running to the bus or carrying groceries upstairs, thes short bursts of (physical) activity that we don’t register mentally, but do throughout the day and can increase our heart rate.”
The study highlights the importance of incorporating even small amounts of intense activity into daily routines. Professor Lear noted that the findings are particularly significant for women, who often have lower cardiorespiratory fitness than men. He added, “This again helps us understand the value of the little bursts of activity that we have but don’t recognize. We might potentially be doing them, but we don’t realize it.”
Current recommendations suggest 150 minutes of moderate-intensity activity weekly. However, Professor Lear points out that many people fall short of this goal. he emphasizes the value of even partial adherence to these guidelines: “we know that even those who respect half of these recommendations do better than the others. They are less sick and have a lower risk of premature death than those who do nothing.”
The study’s findings offer a more accessible and realistic approach to improving cardiovascular health. Professor Lear concludes, “A little is better than none, but a lot is better than a little,” and suggests that incorporating just one or two minutes of vigorous activity several times a day is a feasible goal for most people.
This research provides valuable insights for Americans seeking to improve their heart health. By incorporating short bursts of intense activity into their daily lives, individuals can take significant steps towards a healthier future, irrespective of their ability to commit to longer, structured workouts.
Key Takeaways:
- Short bursts of intense activity (VILPA) significantly reduce cardiovascular risk, especially for women.
- Even 1-4 minutes of VILPA daily can yield significant health benefits.
- This research offers a more attainable approach to heart health for those who struggle with traditional exercise guidelines.
- The study emphasizes that “a little is better than none” when it comes to physical activity.

A New Perspective on Physical Activity
Today we are joined by Dr. Emily Carter, Professor of Exercise Physiology at the University of California, San Diego, to discuss this fascinating new research.Dr.Carter, can you tell our readers about this study and its key findings?
Dr. Carter: This study, which involved over 81,000 middle-aged adults in the UK, used fitness trackers to monitor the physical activity of participants over a week. The researchers focused on “Vigorous Intensity of daily Living Physical Activity” or VILPA. This means short bursts of intense effort,like running for the bus,carrying heavy groceries,or climbing stairs quickly.
They found that even just a few minutes of VILPA per day could significantly reduce the risk of heart disease, heart attacks, and heart failure, especially in women. For example. women who averaged just over 3 minutes of VILPA daily had a remarkable 45% lower risk of major cardiovascular events.
Why Are These Findings So Vital?
That’s remarkable. So, why are these findings so meaningful, especially for women?
Dr.Carter: There are a few reasons. Firstly, many people struggle to meet the current recommendations for moderate-intensity exercise, which is 150 minutes per week. This study shows that even small amounts of vigorous activity can have a big impact.
Secondly, women frequently enough have lower cardiorespiratory fitness levels than men, putting them at higher risk for heart disease. This research provides a realistic and achievable way for women to improve their heart health, even if they can’t commit to long workouts.
VILPA: Finding It in Everyday Life
Can you give our readers some examples of how they can incorporate VILPA into their daily routines?
Dr. Carter: Absolutely! Think about the little bursts of effort you already do in a day – rushing to catch your train, playing actively with your kids, or power walking up a hill. These all count as VILPA.
Other examples might include taking the stairs instead of the elevator, doing some vigorous housework like vacuuming or yard work, or even dancing around your living room. The key is to make these bursts of activity more intense,get your heart rate up,and make them a regular part of your day.
Key Takeaways for Our Readers
Dr. Carter, what are the most important takeaways for our readers?
dr. Carter:** This research shows that every little bit counts when it comes to physical activity. Even if you can’t do a full workout, don’t underestimate the power of short bursts of intense effort spread throughout your day.It’s good news for everyone, but particularly for women, showing that even small changes can have a substantial impact on heart health.
Remember, ”a little is better than none,” and it’s never too late to start incorporating more VILPA into your life.
