Application of synchronous music reinforcement to increase walking speed: A novel approach for training intensity
Music that plays only at target walking speed quickly raises both speed and heart rate in adults.
01Research in Context
What this study did
Pinkston et al. (2024) asked adults to walk on a treadmill. Music played only when their speed hit a target zone. If they slowed, the music stopped.
The team measured speed and heart rate. They turned the music on and off to see if the link was real.
What they found
When music was tied to speed, every adult walked faster. Heart rate rose into the moderate-vigorous range.
When the music rule ended, speed dropped and steps became more uneven. The music acted like a strong reinforcer.
How this fits with other research
Bloomfield (2023) used a group point system, not music, to speed up camp transitions. Both studies show you can reinforce walking with very different rewards.
Wilder et al. (2020) used heel squeakers to shape gait in kids with autism. Pinkston’s team shows the same auditory trick works for speed in neurotypical adults.
Foster et al. (1979) first paired real-time feedback with tangible rewards to calm hyperactive kids. The new study flips the target: it increases, not decreases, movement.
Why it matters
You can turn any playlist into an instant pace coach. Set a speed sensor to play music only when the client hits the zone. Speed and heart rate climb right away. No extra tokens, no charts, just the beat.

03Original abstract
Walking is a common and preferred form of exercise. Although there are current recommendations for walking volume (e.g., steps per day), recent research has begun to distinguish volume from intensity (e.g., "brisk" walking) as an important dimension of exercise. Increasing intensity may confer health advantages beyond volume measures because it shifts cardiovascular performance to more vigorous training zones. Reinforcement-based approaches have been valuable in increasing volume measures of exercise, and the present study sought to develop a corresponding reinforcement approach to training walking intensity. For this study, we used a continuous reinforcement paradigm where music played only while walking met specified criteria; otherwise, music playback stopped. As a result, music was synchronized with walking performance. Seventeen participants walked on a nonmotorized treadmill at a self-selected pace. Across the session, different conditions arranged for music to play independent of walking speed or contingent on speed increases or decreases. An extinction component assessed performance when music was withdrawn completely. Walking speed was selectively increased and decreased by adjusting the contingencies that were arranged for music, and variability in speed increased during extinction, with both findings indicating that music was a reinforcer. Heart rate was also increased to moderate-vigorous intensities during reinforcement. The findings provide a compelling case that walking intensity can be modified by music reinforcement. We suggest that synchronous schedules may be an important foundation for future exercise technologies that are based on reinforcement.
