Intervention: Respiratory exercise protocol with the modified Pachon's incentive
Description: With the participant sitting on a chair, with their back against the backrest, they will hold the device with the hand that is most comfortable for them and place the mouthpiece in their mouth, ensuring a correct seal with their lips.~You will be asked to take a slow, deep breath, fully stretching the condom, and hold your breath for at least 5 seconds. Expiration will be performed passively through the device without removing it from the mouth and without performing any forced maneuver.~There will be 3 series of 10 breaths with a 1-minute rest between series. The total number of breaths for the entire session will be 30; the maneuver will end once the series and repetitions are finished. You will be asked to remove the mouthpiece from your mouth and breathe for 3 minutes at a gentle intensity through your nose without extra effort.~All these instructions will be explained through a video.
