Research Published in European Heart Journal Shows Short Bursts of Intense Exercise Can Deliver Significant Health Benefits

(IN BRIEF) New research published in the European Heart Journal reveals that even short periods of vigorous physical activity can significantly reduce the risk of major diseases, including heart disease, diabetes, inflammatory conditions, and dementia. The study, based on data from over 96,000 UK Biobank participants, found that individuals who engaged in higher-intensity activity—even for just a few minutes daily—experienced substantial health benefits, including reduced mortality risk. The findings suggest that exercise intensity may be as important, or in some cases more important, than total activity time, particularly for inflammatory diseases. Researchers emphasize that simple daily actions such as brisk walking or climbing stairs can make a meaningful difference, though exercise should always be tailored to individual health conditions.

(PRESS RELEASE) SOPHIA ANTIPOLIS, 30-Mar-2026 — /EuropaWire/ — European Society of Cardiology has highlighted new research published in the European Heart Journal showing that even small amounts of vigorous physical activity each day can significantly reduce the risk of several major diseases. The findings suggest that the intensity of exercise may, in some cases, play a more critical role than the total duration of activity.

The study, conducted by an international team of researchers including Minxue Shen from Central South University in China, analysed data from approximately 96,000 participants enrolled in the UK Biobank. Each individual wore a wrist-based accelerometer for a week, allowing researchers to capture precise measurements of both overall activity and short bursts of vigorous movement that are often overlooked.

Researchers then tracked participants over a seven-year period to assess the development of eight major health conditions, including cardiovascular disease, irregular heart rhythm, type 2 diabetes, inflammatory diseases such as arthritis, chronic respiratory and kidney diseases, liver disease, and dementia, as well as overall mortality.

The results showed that individuals who incorporated a higher proportion of vigorous activity into their routines experienced significantly lower risks across all studied conditions. Compared with those who did not engage in vigorous activity, participants with the highest levels saw a 63% reduction in dementia risk, a 60% reduction in type 2 diabetes risk, and a 46% lower risk of death.

Importantly, these benefits were observed even when the total amount of vigorous activity was relatively low. Short, intense bursts of movement—such as running to catch transport, climbing stairs quickly, or brisk walking—were enough to deliver measurable health improvements.

The research also revealed that the importance of exercise intensity varies depending on the condition. For inflammatory diseases like arthritis and psoriasis, intensity appeared to be the primary factor influencing risk reduction. In contrast, for conditions such as diabetes and chronic liver disease, both the duration and intensity of activity contributed to improved outcomes.

Professor Shen explained that vigorous activity triggers physiological responses that are less pronounced during moderate exercise. These include improved cardiovascular efficiency, increased flexibility of blood vessels, enhanced oxygen utilisation, and reduced inflammation. Additionally, vigorous movement may stimulate brain-supporting chemicals that help protect against cognitive decline.

The findings suggest that incorporating even a few minutes of higher-intensity activity into daily routines can provide meaningful health benefits. As little as 15 to 20 minutes per week of such activity was associated with improved outcomes, highlighting the accessibility of this approach.

The researchers noted that current physical activity guidelines tend to focus on total time spent exercising, but their results indicate that the composition and intensity of that activity should also be considered. This could pave the way for more tailored recommendations based on individual health risks.

However, the researchers also cautioned that vigorous activity may not be suitable for everyone, particularly older adults or individuals with certain health conditions. In such cases, any increase in physical movement remains beneficial, and exercise should be adapted to individual capabilities.
