From HIIT to HIIPA

Bringing the science of high intensity interval training (HIIT) into everyday life could be the key to helping unfit, overweight people get more of the exercise they need to improve their health, according to an international research team.

From washing the car to climbing stairs or carrying groceries, each of these activities is an opportunity for short sharp bursts of ‘High Intensity Incidental Physical Activity’, HIIPA for short.

In an editorial, published today in the British Journal of Sports Medicine, Emmanuel Stamatakis and colleagues argue that when considering differences in physical capabilities by age, sex and weight, many daily tasks can be classified as ‘high intensity’ physical activity. That is, the kind of activity that gets you out of breath enough to boost your fitness.

They say incorporating these kinds of activities into routines a few times a day will see significant health benefits for the majority of adults.

For the typical middle-aged woman, 60 percent of whom are overweight and/or unfit activities like running and playing with children at children’s pace, walking uphill or riding home from work all expend well over six times as much energy per minute than when at rest, which is the standard measure for high intensity activity.

The authors suggest over the course of the day these activities could be used in the same way that the popular high intensity interval training (HIIT) works by repeating short sessions of high intensity exercise with rests in between.

There is a lot of research telling us that any type of HIIT, irrespective of the duration and number of repetitions is one of the most effective ways to rapidly improve fitness and cardiovascular health and HIIPA works on the same idea.

The authors propose that significant health benefits could be gained by doing three to five brief HIIPA sessions totalling as little as five to 10 minutes a day, most days of the week.

We know from several large studies of middle aged and older adults that doing vigorous exercise has great long-term health benefits, but many people find it very difficult to start and stick to an exercise program.

The beauty of HIIPA and the idea of using activities we are already doing as part of everyday life is that it is much more realistic and achievable for most people.

Other practical advantages are nil costs, no need for equipment and no concerns about a lack of skill or fitness.

It’s just about making good decisions like parking the car at the edge of the carpark and carrying shopping for 50 or 100 metres.”

The editorial, co-authored by academics from the University of Sydney, Loughborough University, University College London, Norwegian University of Science and Technology, and the National Research Centre for the Working Environment (Denmark), was prompted by recent changes to the 2018 US Physical Activity Guidelines, the most comprehensive review of physical activity and health.
