Question: In adults in the general population, how effective are financial incentives, compared to no incentives or any other intervention, in improving and/or increasing adherence to physical activity?

Answer:

Evidence from one systematic review (SR) suggests that financial incentives increase adherence to physical activity in the short-term (four-weeks to six-months) amongst healthy, white, educated, middle to high-income, USA-residing adults. It is unclear whether financial incentives increase physical activity-adherence in the longer-term and amongst different populations (e.g. non-white populations with lower health and socioeconomic status).
