Maintained Physical Activity Induced Changes in Delay Discounting.

Area of Science:

• Behavioral Economics
• Psychology
• Exercise Science

Background:

• Lower rates of delay discounting are associated with increased physical activity.
• Limited research exists on whether physical activity interventions can alter delay discounting rates.

Purpose of the Study:

• To evaluate the treatment and maintenance effects of a novel, effort-paced physical activity intervention on delay discounting.
• To investigate the relationship between physical activity improvements and changes in delay discounting.

Main Methods:

• A two-experiment series utilizing multiple baseline designs.
• Participants engaged in an effort-paced physical activity intervention, tracking perceived effort.
• A lap-based method was used for exercise monitoring.

Main Results:

• Treatment-induced changes in delay discounting were maintained at follow-up for 13 of 16 participants.
• Statistically significant group-level improvements in physical activity and delay discounting were observed from baseline to treatment and maintenance phases.
• Percentage change in delay discounting correlated significantly with session attendance and relative pace improvement.

Conclusions:

• A novel, effort-paced physical activity intervention can effectively reduce delay discounting.
• The observed reductions in delay discounting are sustainable.
• Physical activity interventions show promise for enhancing self-control and future-oriented decision-making.
