Table 1. Relative activity (EMG) of the diaphragm and IC and SCM muscles during 40%, 60%, and 80% IMT intensities.

Variable	0% Intensity	40% Intensity	60% Intensity	80% Intensity
	Mean (SD)
DI activity (%)	37.3 (15.5)	28.9 (16.9)	24.9 (17.3)a	21.0 (13.3)a	*
IC activity (%)	26.7 (8.4)	23.9 (13.7)	20.8 (10.9)	19.2 (11.4)	*
SCM activity (%)	35.8 (14.1)	47.1 (19.0)	54.2 (19.0)a	59.7 (18.3)a, b	*

EMG: electromyography; DI: diaphragm; IC: intercostal; SCM: sternocleidomastoid; MIP: maximal inspiratory pressure; IMT: inspiratory muscle training; 40% intensity IMT: participants who trained at 40% of sustained maximum inspiratory effort; 60% intensity IMT: participants who trained at 60% of sustained maximum inspiratory effort; 80% intensity IMT: participants who trained at 80% of sustained maximum inspiratory effort; *p < 0.05, ^a Significantly different from baseline, ^b significantly different from 40% intensity IMT
