A recent study led by Emmanuel Stamatakis reveals that incorporating more physical activity into daily life can significantly enhance cardiovascular fitness. Published in the journal Circulation, the study emphasizes that even short bursts of activity, lasting from 30 seconds to five minutes, can be accumulated throughout the day to foster better heart health.
Recent research shows that as little as one minute of vigorous-intensity incidental physical activity can make a meaningful difference in reducing heart disease and mortality risk. This brief jolt is equivalent to three to 3.5 minutes of moderate-intensity exercise. Plus, research suggests that as little as 35 to 48 minutes of light incidental physical activity can help lower the risk of heart disease and death. This positive effect is similar to only a minute of vigorous exercise.
Stamatakis’s findings point to a big health breakthrough. Put simply, just three minutes of moderate incidental physical activity a day is enough to dramatically reduce your chances of cardiovascular diseases and premature death. This new knowledge could not have come at a more important time. Yet shockingly, only 15-20% of middle-aged and older adults get the exercise they need on a regular basis, despite the fact that physical inactivity leads to an estimated six million deaths annually around the world.
Stamatakis emphasized incidental physical activity—activity achieved unintentionally through daily tasks—is built into our lives. This allows you to squeeze in workouts without having to carve out dedicated time for fitness. He underscored the powerful impact that daily life, such as gardening, can have on heart health. He further remarked that taking the stairs rather than the elevator can go a long way.
“Incidental physical activity, things we do as part of our daily routines, offers many, largely untapped, opportunities,” – Emmanuel Stamatakis
The study did take advantage of the novel UK Biobank accelerometry substudy. Participants wore accelerometers on their wrists for increasing their actual physical activity levels. The results indicate that moderate incidental physical activity averages around 24 minutes per day can lead to a substantial reduction in all-cause mortality—up to 47%.
At the heart of the study was an analysis of connection between levels of physical activity and health outcomes. Only 4.5 minutes of vigorous incidental activity per day and 23.8 minutes moderate incidental activity are needed to reduce the risk of cardiovascular events and mortality.
“Start from any amount that feels comfortable and build to at least around four to five minutes of vigorous or 15–25 minutes of moderate intensity activity a day, or equivalent combinations of moderate and vigorous,” – Emmanuel Stamatakis
As for their own work, Stamatakis admitted that promoting incidental activity is surprisingly difficult. We’ve got to change the paradigm. He shared some of his frustrations with existing research. It largely emphasizes formal exercise and lengthy workouts while ignoring the benefits of brief, incidental activities.
“However, we do not understand very well what is the best way to promote incidental activity, and how to support people [integrating] it into their day-to-day routines,” – Emmanuel Stamatakis
Hoang Nguyen, a cardiologist, motivates his patients to be physically active and to increase their cardiovascular fitness level. Rather than signing them up for formalized exercise programs, he recommends they take part in routine movements. He suggested practical ways individuals can increase their physical activity levels:
“These include using the stairs rather than the elevator when going to work or running errands. They can walk to their local restaurants rather than drive there if feasible,” – Hoang Nguyen
Nguyen pointed out that finding innovative methods to promote healthy living with minimal effort can significantly impact longevity and decrease healthcare system strain.
“Finding new ways to promote healthy living with minimal effort and resources have a significant impact on one’s longevity, morbidities, and strain on the healthcare system,” – Hoang Nguyen
The research provides a fresh perspective on the potential benefits of shorter bouts of vigorous exercise in improving cardiovascular health. Grant Simons noted the importance of these findings:
“This finding is exciting due to its analysis of short bursts of activity, which is new and noteworthy,” – Grant Simons
