Measurement of the Diaphragm Loading During the Training With an Inspiratory Muscle Trainer Device

What this Trial Is About

Researchers are investigating the muscles involved during training with an Inspiratory Muscle Trainer (IMT) device in healthy adults. The study aims to measure diaphragm loading while using the IMT device at various resistive loads, as there is uncertainty about which muscles contribute most during this type of training. This observational study involves healthy volunteers and uses advanced pressure monitoring to gather detailed muscle activity data. Participants will use the Threshold IMT device by Philips, which applies resistive loads based on each person's maximal inspiratory pressure. The training involves random loads increasing by tens of percentages from 10% up to 100%, with each load maintained for five breaths. During this, esophageal and gastric pressures, as well as transdiaphragmatic pressure, are recorded to analyze diaphragm involvement. Throughout the study, each participant will be monitored using esophageal and gastric manometry while performing breathing efforts with the device. Data collected includes esophageal pressure, gastric pressure, and transdiaphragmatic pressure to calculate diaphragm collaboration at each load. The primary outcome focuses on diaphragm intervention during different resistive loads over one year, with safety and muscle function closely observed during the process.
