With new year's eve just around the corner, many people will start thinking about exercising more. And while it's beneficial to exercise more to lose weight and improve health, recent research from the University of Sydney claims you can significantly reduce the risk of cancer and cardiovascular disease mortality by doing only 1-minute bursts of exercise a few times a day.
Researchers observed over 25,000 'non-exercisers' (mean age 61.8 years, 14,178 women/11,063 men) for an average of 6.9 years to find that brief bursts of vigorous intermittent lifestyle physical activity (VILPA) were associated with 38%-40% reduction in all-cause and cancer mortality risk and a 48%-49% reduction in CVD mortality risk.
"Moreover, the sample median VILPA duration of 4.4 min per day was associated with a 26%-30% reduction in all-cause and cancer mortality risk and a 32%-34% reduction in CVD mortality risk", the study adds, meaning that only four sessions of one minute-long exercise sessions are enough to help you potentially live longer And we thought HIIT was the most time efficient workout mode to improve cardiovascular fitness.
VILPA can be any activity that elevates the heart rate, such as running up the stairs or brisk walking to catch the train. "Upping the intensity of daily activities requires no time commitment, no preparation, no club memberships, no special skills", Emmanuel Stamatakis, lead author of the paper and Professor of Physical Activity, Lifestyle and Population Health at the University of Sydney's Charles Perkins Centre, told ScienceDaily (opens in new tab), "It simply involves stepping up the pace while walking or doing the housework with a bit more energy."
Interestingly, researchers used wearable data to "capture unexplored movement patterns", the paper says. The best Fitbits and many of the best fitness trackers are famous for monitoring and recording said movement patterns, even if users don't log them as workouts; Fitbit's Active Zone Minutes feature is built around this concept.
We'd recommend exercising for longer if you want to lose weight or build muscle; however, four minutes a day might be enough to prolong your life, and we hope that even lazy people agree that doesn't sound like too much effort for a lot of gains.
