Weekend exercise may be as good as daily workouts

People who exercise mainly on the weekends may reap significant health and survival benefits, on par with people who work out more regularly, researchers said on Monday.


Currently, experts recommend 150 minutes of moderate physical activity per week, or 75 minutes of vigorous exercise.


But no consensus has been reached on just how often a person needs to exercise, and whether activities should be done daily or condensed into shorter periods.


The findings in the Journal of the American Medical Association (JAMA) Internal Medicine showed that people who pack all of their exercise into one or two days of the week — often referred to as “weekend warriors” — appear to lower their risk of dying about as much as people who exercise three times a week or more. The study looked at survey responses from nearly 64,000 people, and grouped them in four categories: inactive, insufficiently active, weekend warrior and regularly active. All three groups of people who got exercise fared better than people who were inactive. Comparing weekend warriors to inactive adults, researchers found that those who exercised just one or two days a week saw about a 30 per cent lower risk of dying.


The risk of cardiovascular death for weekend warriors was 40 per cent lower and the risk of cancer death was 18 per cent lower than among inactive adults.


Similar effects were seen among insufficiently active people who got less than the recommended amount, and regularly active people who exercised three or more days per week. Compared with the inactive participants, the risk of dying of any cause among insufficiently active participants was 31 per cent lower, and 35 per cent lower in regularly active participants.


The risks of dying from heart disease or cancer among insufficient exercisers and regular exercisers were also quite similar — each within a few percentage points — to the weekend warriors’ reduced risk.


“It is very encouraging news that being physically active on just one or two occasions per week is associated with a lower risk of death, even among people who do some activity but don’t quite meet recommended exercise levels,” said senior author Emmanuel Stamatakis, associate professor at the University of Sydney.


“However, for optimal health benefits from physical activity it is always advisable to meet and exceed the physical activity recommendations.”


Based on survey data


The study stopped short of proving cause and effect, because it was based on people who filled out health surveys in Britain, and relied on their self-reported exercise intensity and duration. Researchers also cautioned that since 90 per cent of the respondents were white, the benefits of weekend exercise might not be generalisable to the entire population.


On average, weekend warriors tended to be men and averaged 300 minutes of weekly exercise in one or two days, said the study. The types of exercise people did included gardening, walking, cycling, running and organised sports.


By far, most of the survey respondents were inactive — nearly 63 per cent. Another 22 per cent were insufficiently active. Just 3.7 per cent were weekend warriors, and 11 per cent were regular exercisers. — AFP
