Summary

This study aims to investigate the effects of respiratory muscle training on tongue muscle function in healthy subjects. We hypothesize that respiratory muscle training can improve strength and endurance of the tongue muscles.

  • Healthy

Interventions

DEVICE

Sham

A pressure threshold loading device will be used: the POWERbreathe Ex1 EMT Medic or MR, but with the resistance mechanism inside removed and replaced by a plastic ball. The same instructions will be given as for the EMT group, except that there will be no or minimal resistance (less than 6 cmH2O). There will be no change in resistance over the weeks.

DEVICE

IMT

Description: A pressure threshold loading device will be used: the POWERbreathe Medic (load range 10-90 cmH2O). Participants will be instructed to exhale passively during normal tidal breathing through the training device (until functional residual capacity) and to perform deep inspirations against the external load. The first week, the resistance will be fixed at 30% of the baseline measured maximal inspiratory pressure (MIP). Participants will be instructed to increase the resistance by 10% of the baseline set resistance each week.

DEVICE

EMT

A pressure threshold loading device will be used: the POWERbreathe Ex1 EMT Medic (load range 10-90 cmH2O) or POWERbreathe Ex1 EMT MR (load range 35-175 cmH2O) depending on their baseline MEP measurement. Participants will be instructed to inhale quietly during normal tidal breathing through the training device and to perform rapid and deep exhalation against the external load. The first week, the resistance will be fixed at 30% of the baseline measured MEP. Participants will be instructed to increase the resistance by 10% of the baseline set resistance each week.
