The effectiveness of reinforcing exercise behavior with material incentives is unclear.
This study aims to conduct a systematic review of existing research on material incentives for exercise, organized by incentive strategy.
Ten studies conducted between January 1965 and June 2013 assessed the impact of incentivizing exercise compared to a non-incentivized control.
There was significant heterogeneity between studies regarding reinforcement procedures and outcomes. Incentives tended to improve behavior during the intervention while findings were mixed regarding sustained behavior after incentives were removed.
The most effective incentive procedure is unclear given the limitations of existing research. The effectiveness of various incentive procedures in promoting initial behavior change and habit formation, as well as the use of sustainable incentive procedures should be explored in future research.
