Four-minute workout cuts diabetes risk 36%

Monash University said on April 29 that a study led by researchers including former University of Sydney investigator Kar Hau Chong found that less than four minutes a day of short bursts of moderate to intense movement was associated with a lower risk of developing type 2 diabetes. The findings were published in *Diabetes Care* and drew on data from 22,706 adults in the United Kingdom who did not do leisure-time exercise, according to Monash and the paper’s preprint record. GB News reported the findings on Aug. 6 and said the exercises highlighted included brisk stair climbing and quick walking. The study adds to a line of research on “vigorous intermittent lifestyle physical activity,” or short bouts of harder movement woven into daily routines rather than planned workouts. ### How short was the activity researchers studied? Monash University said the activity could last as little as 30 seconds at a time and was grouped into what researchers called “physical activity micropatterns.” The university said the study identified two categories: vigorous intermittent lifestyle physical activity, or VILPA, and a moderate-to-vigorous equivalent. (monash.edu) The Monash release said an average of 10 daily VILPA bursts of up to a minute at a time was associated with a 36% lower risk of type 2 diabetes. It said an average of 39 bursts of moderate-to-vigorous activity lasting up to three minutes at a time was associated with a 41% lower risk. ### What did participants actually do? (monash.edu) Professor Emmanuel Stamatakis said the study did not involve gyms, running or planned exercise that required memberships, travel or sports clothing. He said the activities could be as simple as taking stairs at a brisk pace instead of a lift or carrying groceries to a car instead of using a trolley. (monash.edu) GB News reported the same practical examples in its Aug. 6 story, describing brisk stair climbing and a quick walk as examples of the kind of movement examined. The outlet said the benefit compared favorably with longer exercise sessions. ### Who ran the research and where did it appear? (monash.edu) The preprint record names Kar Hau Chong, Matthew N. Ahmadi and Emmanuel Stamatakis among the authors and lists the University of Sydney’s Charles Perkins Centre and School of Health Sciences among the affiliations. The same record says the paper was first posted as a preprint on medRxiv and was later published in *Diabetes Care* with DOI 10.2337/dc25-3018. (msn.com) Monash University said Chong conducted the research while at the University of Sydney’s Charles Perkins Centre and identified him as lead author from the University of Wollongong at the time of the release. That release described the work as the first study to show a link between short bursts of physical activity and lower risk of developing type 2 diabetes. (medrxiv.org) ### What did the study actually show — and what didn’t it prove? The Monash release said the study followed 22,706 non-exercising UK adults for nearly eight years and found they were 36% less likely to develop type 2 diabetes if they did up to four minutes a day of micropatterns-based activity at intervals through the day. The wording in the release and preprint describes an association, not a randomized trial proving cause and effect. (monash.edu) The paper’s preprint abstract said that among adults who do not engage in leisure-time exercise, brief intermittent bouts of moderate-to-vigorous activity during daily routines “may be a promising strategy” for prevention of type 2 diabetes. That is the formulation researchers used, and it stops short of claiming that four minutes alone will prevent the disease in every population. ### Where can readers look next? (monash.edu) *Diabetes Care* lists the journal as the publication venue for the study, and the preprint record identifies the final article DOI as 10.2337/dc25-3018. Monash University’s April 29 release names Chong and Stamatakis as researchers to watch on the next round of reporting on short-burst daily activity and diabetes risk.
