ClinConnect Summary

This is a randomized control trial. The fatigue group (EG) will perform the inspiratory muscle fatigue protocol using a specific inspiratory endurance test, in which volunteers, one-on-one, and in a single session, will breathe against submaximal inspiratory loads equivalent to 60% of their Maximum Inspiratory Pressure (MIP) through a threshold valve device. The participants will follow a free pattern of breathing until they are unable to establish flow during at least 3 maximum inspiratory efforts.

The activation group (AG) will perform the protocol of 2 sets of 30 repetitions at 15% of t...
