Published in聽聽today, the study is led by the University of Sydney鈥檚聽Charles Perkins Centre聽in Australia. It is the first to accurately measure the health benefits of what researchers have termed 鈥榲igorous intermittent lifestyle physical activity鈥� or VILPA.

VILPA is the very short bouts of vigorous activity (up to one to two minutes) we do with gusto each day, like running for the bus, bursts of power walking while doing errands or playing high-energy games with the kids.聽聽

The researchers found that just three to four one-minute bouts of VILPA every day is associated with up to 40 percent reduction in all-cause and cancer-related mortality, and up to a 49 percent reduction in death related to cardiovascular disease.聽 聽

鈥淥ur study shows similar benefits to high-intensity interval training (HIIT) can be achieved through increasing the intensity of incidental activities done as part of daily living, and the more the better,鈥� said lead author Emmanuel Stamatakis,聽Professor of Physical Activity, Lifestyle and Population Health at the聽University of Sydney's Charles Perkins Centre.

聽鈥淎 few very short bouts totalling three to four minutes a day could go a long way, and there are many daily activities that can be tweaked to raise your heart rate for a minute or so.鈥�

The do not take part in regular exercise or sport, but Professor Stamatakis said the study reveals how incidental physical activity can overcome many barriers.

鈥淯pping the intensity of daily activities requires no time commitment, no preparation, no club memberships, no special skills. It simply involves stepping up the pace while walking or doing the housework with a bit more energy,鈥� he said.

• 聽About 89 percent of all participants did some VILPA.
• Among those who did VILPA:
• 93 percent of all VILPA bouts last up to 1 minute
• On average each day participants did eight VILPA bouts of up to 1 minute each, totalling 6 minutes a day.
• On average each VILPA bout lasted around 45 seconds.聽
• The steepest gains were seen when comparing those with around four to five bouts per day to those with no VILPA.
• However, larger benefits were found with larger VILPA amounts, suggesting the more the better.聽聽
• The maximum of 11 bouts per day was associated with a 65 percent reduction in cardiovascular death risk and 49 percent reduction in cancer-related death risk, compared to no VILPA.聽

Interestingly, a comparative analysis of the vigorous activity of 62,000 people who regularly engaged in exercise found comparable results. This implies that whether the vigorous activity is done as part of structured exercise or housework do not compromise the health benefits.

Researchers used wrist-worn tracker data from聽, a large-scale biomedical database, to measure the activity of over 25,000 鈥榥on-exercisers鈥�, participants who self-reported that they do not do any sports or exercise during leisure time.聽 聽

By this method, the researchers could conclude that any activity recorded by this group was incidental physical activity done as part of everyday living.

The team then accessed health data that allowed them to follow participants over seven years.

The studies are observational, meaning they cannot directly establish cause and effect. However, the researchers took rigorous statistical measures to minimise the possibility that results are explained by differences in health status between participants.

"These findings demonstrate just how valuable detailed and objective measures of physical activity can be when collected on聽a聽large-scale population.聽We are incredibly grateful to all of the聽100,000聽UK Biobank聽participants聽who聽wore an activity monitor for 7 days to generate these valuable聽data," said Professor Naomi Allen, Chief Scientist of UK Biobank.

The international team from the University of Sydney, the University of Oxford鈥檚 Big Data Institute (UK), University College London (UK), University of Glasgow (UK), University of Southern Denmark and McMaster University (Canada) are calling for physical activity guidelines and clinical advice to be updated to keep pace with this evolving area.

Current global guidelines imply that the health benefits of vigorous-intensity physical activity are gained through structured physical activity such as sport or running during leisure time.

It was only in 2020 that the聽WHO global Guidelines on Physical Activity and Sedentary Behaviour,聽co-chaired by Professor Stamatakis, acknowledged that 鈥榓ll activity counts鈥� and the stipulation that activity should be accumulated in 10-minute bouts was removed.

鈥淥ur previous knowledge about the health benefits of vigorous physical activity comes from questionnaire-based studies, but questionnaires cannot measure short bouts of any intensity,鈥� said Professor Stamatakis.

鈥淭he ability of wearable technology to reveal 鈥渕icropatterns鈥� of physical activity, such as VILPA, holds huge potential for understanding the most feasible and time-efficient ways people can benefit from physical activity, no matter whether it is done for recreation or as part of daily living.鈥�
