Here's some good news for those who don't like spending hours in the gym.
Researchers from the University of Sydney have reported that just three to four one-minute bursts of "huffing and puffing" during daily tasks have been linked with large reductions in the risk of early death, particularly from heart 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.
"A 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."
For the study, the team analysed wrist-worn tracker data from UK Biobank. They measured the activity of over 25,000 "non-exercisers", that is, participants who self-reported that they do not do any sports or exercise during leisure time.
Accordingly, they found just three to four one-minute bouts of 'vigorous intermittent lifestyle physical activity', or VILPA, each day is associated with an 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.
In light of the findings, Professor Stamatakis noted that adults can up their fitness levels by undertaking simple activities like running for the bus, bursts of power-walking while doing errands, or playing high-energy games with kids.
"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 added.
The full results of the study were published in the journal Nature Medicine.
