It may take only a handful of change to make a lifetime of positive changes in the lives of many when it comes to sustaining physical activity, according to a Western-led study.

"We know there is a strong relationship between and health. Yet, the average adult accumulates only about half the recommended 10,000 daily steps," explained Kinesiology professor Marc Mitchell, lead researcher on the study. "Our pandemic carries a massive financial burden, too. It is imperative we find new ways to motivate movement—even if that means paying some people to be active."

The use of to promote physical has grown in popularity due to that make it easier to track and reward physical activity, such as smartphone applications and wearable activity trackers.

The team's analysis showed that modest incentives—averaging $1.40 per day to as small as 10 cents per day—increased physical activity for short and long durations by about 10-15 per cent, and up to 75 per cent with better incentive designs. Furthermore, after the incentives were removed, physical activity remained elevated. This suggests that a short-term incentive 'dose' may promote sustained physical activity.

"This evidence contradicts the prevailing sentiment that extrinsic rewards undermine to get more active and damage the potential for sustained improvements," Mitchell said. "In fact, these rewards may be just what people need, if even for a short period, to stimulate a more active, healthy lifestyle."

The study, "Financial incentives for physical activity in adults: and meta-analysis," was recently published in the British Journal of Sports Medicine.

Mitchell points to behavioural economics principles to explain these results such as the 'present bias' which states people tend to respond more to the immediate costs and benefits of their actions at the expense of their long-term well-being. "By providing immediate incentives we harness the inherent human 'present bias," essentially tipping daily decisional scales towards more physical activity," he continued.

"Our new ability to track and reward physical activity with the latest in smartphone technology lends itself to population-level interventions where walking is focus," Mitchell said. "It also has the potential to cut the cost of programs by more than 500 per cent making them much easier to implement on a large scale."

Mitchell's team analysed data from 23 studies published from 2012-18 to examine the impact of incentives on physical activity. These studies included 6,074 participants with an average age of 41 years, 64 per cent of whom were female.
