A recent study published in the British Journal of Sports Medicine has found that short bursts of intense physical activity can significantly decrease the risk of cardiovascular events for those who typically do not engage in regular exercise. The research draws on data from over 22,000 participants, with an average age of 62, who wore an accelerometer on their wrist for a week. This device enabled researchers to meticulously track daily movements in 10-second increments, providing an unprecedented level of detail in understanding daily activity patterns.
The study revealed that women who incorporated small amounts of vigorous intermittent lifestyle physical activity (VILPA) into their daily routines experienced a reduction in major cardiovascular issues such as heart attack, heart failure, and stroke. The benefits were particularly pronounced for women who committed to these short bursts of activity almost daily, averaging about nine to 10 bursts per day. These women were found to be 51% less likely to experience a heart attack and 67% less likely to develop heart failure compared to their peers who did not engage in VILPA.
However, the study's findings are tempered by its observational nature and the relatively short time frame over which data was collected. Emmanuel Stamatakis, the study's lead author, notes the potential limitations but emphasizes the value of incorporating VILPA into daily life.
“However, we took several statistical measures to narrow down interpretation to causation,” – Stamatakis
Despite the limitations, Stamatakis and his colleagues believe that integrating these short, vigorous activities into daily routines can be beneficial for heart health. This aligns with updated guidelines from the World Health Organization (WHO), which acknowledge that even shorter bouts of activity can contribute positively to overall health. These recommendations suggest that people aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous activity per week.
“These are short bursts of vigorous incidental activity, typically lasting 10 seconds to one minute, that are part of people’s daily living,” – Stamatakis
Ankit Shah, MD, MPH, supports the notion that individuals who find it challenging to commit to structured exercise programs can still improve their cardiovascular health by seeking opportunities for short bursts of movement throughout the day.
“All of that can go a long way,” – Shah
Alan Rozanski, MD, also highlights the importance of spreading awareness about VILPA among both healthcare professionals and the general public.
“Most doctors don’t necessarily know about it,” – Alan Rozanski, MD
“That’s a message that we have to get out to the public,” – Alan Rozanski, MD
“Patients are more likely to sign on. And they’re more likely to feel good about themselves that they did that,” – Alan Rozanski, MD
Despite the encouraging findings, Stamatakis cautions against viewing VILPA as a panacea for the complex issue of physical inactivity.
“We should not be fooled into thinking that small amounts of VILPA are a quick fix of a complex problem like physical inactivity,” – Stamatakis
Nonetheless, this form of activity may prove more feasible for many individuals as it does not require preparation, significant time commitment, or travel to exercise facilities.
“This kind of activity may be more feasible than structured exercise for many people as it does not require preparations, time commitment, or traveling to a facility to be active,” – Emmanuel Stamatakis, PhD
