Daily Short Bursts of Activity to Prolong Life
Newswise: One-minute bursts of activity during daily tasks could prolong your life, finds study. In good news for those who don’t like playing sport or going to the gym, new research finds just three to four one-minute bursts of huffing and puffing during daily tasks is associated with large reductions in the risk of premature death, particularly from cardiovascular disease.
Published in Nature Medicine today, the study is led by the University of Sydney’s Charles Perkins Centre in Australia. It is the first to accurately measure the health benefits of what researchers have termed ‘vigorous intermittent lifestyle physical activity’ 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.
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.
“Our 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,” said lead author Emmanuel Stamatakis, Professor of Physical Activity, Lifestyle and Population Health at the University of Sydney’s Charles Perkins Centre.
“A few very short bouts totaling 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.”
The majority of adults aged 40 and over do not take part in regular exercise or sport, but Professor Stamatakis said the study reveals how incidental physical activity can overcome many barriers.
“Upping 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,” he said.
What they discovered with participants as part of daily life
- 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.
- 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.
- 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.
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.
How was the study conducted?
Researchers used wrist-worn tracker data from UK Biobank, a large-scale biomedical database, to measure the activity of over 25,000 ‘non-exercisers’, participants who self-reported that they do not do any sports or exercise during leisure time. 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 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.
