Synchronous reinforcement using participant-selected music can produce stepwise increases in walking speed, supporting its potential as a socially significant and low-cost strategy to promote aerobic physical activity.
Key Findings
Results
The majority of participants demonstrated schedule control by maintaining walking speed above criterion during synchronous music reinforcement components.
23 of 30 participants (76.7%) demonstrated schedule control
Schedule control was defined as maintaining walking speed above criterion for the majority of synchronous components
Participants were 30 undergraduate students
The study used a laboratory-based nonmotorized treadmill preparation
Methods
The experimental session consisted of five components across 15 minutes, with individualized speed criteria derived from each participant's baseline walking speed.
Session duration was 15 minutes total
Components included an initial continuous music component (CM 1), three synchronous reinforcement components, and a final continuous music component
During CM 1, participants received continuous access to self-selected music, and their mean speed was used to set individualized criteria
The three synchronous components required speeds of 0.1, 0.2, and 0.3 m/s above CM 1, respectively
Music was delivered contingent on maintaining the required speed during synchronous components
Results
Heart rate increased across components in accordance with the stepwise speed requirements.
Heart rate increases corresponded with the progressively higher speed criteria across synchronous components
Ratings of perceived exertion indicated moderate physical effort
The physiological measures were consistent with the behavioral changes in walking speed
Results
Several participants who did not demonstrate schedule control during synchronous components showed increased walking speed during the final continuous music component.
7 of 30 participants (23.3%) did not demonstrate schedule control during the synchronous reinforcement components
Among these non-responders, some showed increased walking speed during the final continuous music (CM) component
This finding was noted as distinct from the primary pattern of synchronous schedule control
Conclusions
Synchronous music reinforcement using participant-selected music was evaluated as a potential low-cost strategy for promoting aerobic physical activity.
Music was self-selected by participants, which was identified as a relevant feature of the intervention
The authors characterized synchronous music reinforcement as 'socially significant and low-cost'
The preparation was laboratory-based using a nonmotorized treadmill
The study framed the intervention in the context of promoting aerobic physical activity
