A: accumulated mechanical work of breathing (WOB) after 50, 75, and 100% time-to-exhaustion (TTE) trials. Individual values are linked through gray lines along trials. Group means ± SD are also presented for each trial. B: cumulative WOB throughout exercise trials. Values are means ± SD. C: relationship between WOB and minute ventilation (V̇e) during 50, 75, and 100% TTE trials (mean values of WOB and V̇e were calculated in 10% increments throughout exercise). *P < 0.05 vs. 50% TTE trial; †P < 0.05 vs. 75% TTE trial.
