Figure 5.
Effect of accessory respiratory muscle stretching on the total respiratory muscle activity divided by the CW volume (EMG/CW) during exercise.
Notes: Lower EMG/L reflects less respirator muscle activity per liter of breathed air.32 Data are presented as mean ± standard deviation. The exercise was performed with 25% of the maximal predicted load according to Jones et al.24 *P<0.05 CG vs TG (ANCOVA test).
Abbreviations: ANCOVA, analysis of covariance; CG, control group; CW, chest wall; EMG, respiratory muscles electromyography; TG, treatment group.
