Key result
Step-adaptive locomotor-respiratory coupling sound guidance significantly increased frequency coupling in novice female runners outdoors from 26.3% to 69.9% compared to step-only feedback.
Why the study?
Many runners struggle to find a rhythm and experience unexplained breathlessness at exercise onset, which locomotor-respiratory coupling may address through metabolic or perceptual benefits.

Harbour et al. (2023) studied Healthy novice runners (n=16). Step-adaptive locomotor-respiratory coupling (LRC) sound guidance vs. Step-only sound feedback was evaluated on Frequency coupling (percentage of run time 'attached' to the instructed LRC ratio) outdoors (p=0.001). Step-adaptive locomotor-respiratory coupling sound guidance significantly increased frequency coupling in novice female runners outdoors from 26.3% to 69.9% compared to step-only feedback.
