FIGURE 1.
Example of IPTL protocol. Experimental data from a male participant performing IPTL while breathing on the IPTL device with no resistance (i.e., baseline) (a), during the first minute of IPTL (b), and at task failure (c). Data from top to bottom are raw PMO, raw PDI along with a dotted lines representing the target PDI range, filtered EMGDI, EMGSCA, and EMGSCM. EMGDI, diaphragm electromyography; EMGSCA, scalene electromyography; EMGSCM, sternocleidomastoid electromyography; PDI, transdiaphragmatic pressure; PMO, mouth pressure
