Time to completion, muscle activation, and power output during the 5 km cycling time trials performed under normoxic conditions (NORM) and with a hyperoxic inspirate (H). This strategy compensated for the impact of afferent blockade on convective O2 transport and permitted adequate locomotor muscle O2 delivery during the time trial performed with intact (HCTRL) and blocked (HFENT) group III/IV muscle afferents. Panel A, time to complete the 5 km time trials. Panel B, vastus lateralis EMG normalized to the EMG response recorded during pre-exercise maximal voluntary contraction. Panel C, power output during the time trials. * P < 0.05 vs NORM, † P < 0.05 vs HCTRL. (Reprinted from (57). Copyright © 2019 The American Physiological Society. Used with permission.)
