Ventilatory demand is already increased during quiet breathing in patients with COPD, and whether threshold load imposed by IMT would active more accessory muscle remained to be determined. The purpose of this study was to examine diaphragm and sternocleidomastoid (SCM) activation during IMT with intensities of 30% and 50% maximal inspiratory pressure (PImax).enChronic obstructive pulmonary disease; Diaphragm; Group-based trajectory modeling; Inspiratory muscle training; Sternocleidomastoid; Surface electromyography[SDGs]SDG3aged; breathing exercise; chronic obstructive lung disease; diaphragm; electromyography; female; human; inhalation; male; neck muscle; pathophysiology; physiology; Aged; Breathing Exercises; Diaphragm; Electromyography; Female; Humans; Inhalation; Male; Njournal article10.1016/j.rmed.2021.106676347737342-s2.0-85118892589https://api.elsevier.com/content/abstract/scopus_id/85118892589
