Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Inspiratory muscle fatigue group
The EG (experimental group) will perform the diaphragmatic 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 MIP (Maximum Inspiratory Pressure) 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.
Inspiratory muscle fatigue group
The subjects will perform deep inspirations against a threshold device with varying resistances
Inspiratory muscle warm-up group
The inspiratory muscle warm-up group will perform the protocol of 2 sets of 30 repetitions at 40% of their MIP, one-on-one, and in a single session, breathing against submaximal inspiratory loads using a threshold valve device. The participants will follow a free pattern of breathing until complete the protocol.

The subjects will perform deep inspirations against a threshold device with varying resistances
