Adults to clock 150-300 minutes of moderate-intensity activity a week under new national guidelines

SINGAPORE – A revised set of the Singapore Physical Activity Guidelines that focuses on encouraging people to do a variety of activities and be less sedentary was launched by Sport Singapore and the Health Promotion Board (HPB) on Sunday (June 12).

Developed by experts from medical and health fields, the guidelines aim to encourage Singaporeans to strengthen their aerobic fitness, muscular strength, bone strength, flexibility and balance by doing different activities.

But improving all these aspects may not necessarily mean a trip to the gym or park. The activities can also be incorporated into their daily lives – for example, taking a walk to buy food instead of getting it delivered. 

These guidelines were launched in 2011 and the revised version, which are also based on the World Health Organisation’s 2020 recommendations, also includes guidelines for different age groups, pregnant and postpartum women as well as people with disabilities.

A notable change is in the recommended duration of activities for adults. The previous guidelines had called for adults to accumulate 150 minutes of moderate-intensity activity a week with a minimum of 10 minutes each time. But this has been changed to a target range of 150 to 300 minutes a week with no minimum timing for each bout, as activities of any duration are found to be associated with benefits.

Dr Benedict Tan, lead adviser in the guidelines’ advisory committee, said these recommendations are more holistic and comprehensive.

“With more awareness now, we can be more accurate. (Besides cardiovascular or aerobic fitness), there are other aspects of health or fitness that are equally important. Cardio is a good start but it’s not the be all and end all,” said Dr Tan, head of the SingHealth Duke-NUS Sport & Exercise Medicine Centre.

He also noted that while more people are exercising, the number of people with chronic conditions such as diabetes has also gone up slightly.

Studies have shown that doing sufficient physical activity reduces the risks of developing these conditions, cardiovascular disease and various cancers.

Having this approach will hence be in line with the nation’s shift towards preventive care.

“We’ve been tracking physical activity levels and they’ve been going up… but not enough,” he added. “The other issue is the people who really need to be active. That segment tends to be quite stubborn and the numbers are not going up as much as we would like.

“What’s happening is those who are already active are getting more active but the sedentary have remained sedentary. For this version, we needed a refreshed approach to target them.”

The National Population Health Survey 2020 showed that 76.4 per cent of Singapore residents aged 18 to 74 had sufficient (high and moderate) total physical activity (work-related, transport-related and leisure time) down from 80.1 per cent in 2019 and 80.9 per cent in 2017.

The survey also found that 33.4 per cent exercised regularly – an increase from 29.4 per cent in 2017 – while 42.9 per cent did not exercise at all.

About one in 10 (9.5 per cent) had diabetes mellitus during the 2019-2020 period compared with 8.8 per cent in 2017.
