Figure 2. Genioglossus muscle activity during the adaptation and experimental resistive load sessions during the preload, 10 cmH₂O load, and 20 cmH₂O load.

Peak genioglossus muscle activity (peak EMG_GG) and tonic genioglossus muscle activity (tonic EMG_GG) during preload, 10 cmH₂O loads, and 20 cmH₂O loads for the control, deprivation, and fragmentation groups. The blue line indicates the adaptation session and the red line indicates the experimental session. Asterisk (*) indicates a significant (P < .05) load effect. Hash (#) indicates a significant group effect. Error bars are standard error.
