Timing of activation of different inspiratory muscles during incremental inspiratory loading in healthy adults

This study examined whether the onset and duration of electromyography activity of different inspiratory muscles varied during incremental inspiratory threshold loading in 12 healthy adults. As part of the study, participants underwent lung function testing (FEV1, FVC, FEV1/FVC ratio), which was conducted using the Vitalograph COPD-6 device.
