A One Session Gait Retraining Protocol with Metronome Augmentation Increases Cadence in Novice and Recreational Runners.
Angie Huber, Dave Verhoff
PMID 38179589WHAT IT FOUND
One metronome session and two weeks of self-practice raised runners' cadence by 7 steps per minute.
This change did not alter pain, effort, heart rate, or other movement patterns. The increase was smaller than the 5-10% threshold often cited for injury risk reduction.
Key findings
01The intervention group increased their average cadence over the entire run compared to the control group.
02There were no significant differences between groups in heart rate, perceived exertion, or distance run.
03No significant differences were found in biomechanical variables such as stance duration, vertical excursion, knee flexion, or lumbar flexion.

What it does not show
The study included only novice and recreational runners, so results may not apply to experienced runners or those with different running volumes. The intervention required participants to complete at least four independent sessions over two weeks, but compliance with this requirement is not detailed in the text provided. The observed cadence increase (4.14%) was smaller than the 5-10% target set in the protocol, which may have limited the detection of biomechanical changes. Inertial measurement units were used for data collection, which have a known margin of error compared to optical motion capture systems. The study was not blinded during the intervention phase due to the nature of the treatment, although researchers were blinded to allocation until the intervention began.
Declared interests
The authors declared no competing or conflicts of interest, and no funding was received for the project.
The easy way to misread this
Do not assume this protocol reduces injury risk. While cadence increased, the change was less than 5%, and no other biomechanical factors linked to injury were altered. The study did not measure injury incidence.
