Abstract

This study explored if there was a difference in peak ground reaction force (GRF) of walking depending on the phase of respiration (inspiration or expiration) at initial contact. Twenty-five individuals were tested and grouped as inhalers or exhalers. Data was collected for peak GRF using an Advanced Mechanical Technology force platform and phase of respiration using a CapnoTrainer® capnography unit at initial contact for 5 walking trials at a controlled velocity. An Independent Samples t-Test was used to examine the data with an alpha level p<.05. The results suggested that there was no difference in peak GRF for those that inspired/expired at initial contact. Future research will explore the effects of breathing on walking/running at different speeds/inclinations where breathing retraining has been proposed in treating some overuse injuries.
