Figure 1. Effect of attenuating group III/IV afferent feedback on power output and quadriceps EMG during 5 km cycling time trial .

Each data point represents the average over the preceding 100 m section. Vastus lateralis (VL) and rectus femoris (RF) RMS EMGs were normalized to the RMS recorded during pre‐exercise MVC. Subjects were required to reach an individual target power output (260 ± 15 W) before the race was launched. Although the overall VL and RF EMGs were significantly higher during FENT (○) compared to CTRL (●), the average power output was similar between the two trials. W _peak: peak power output measured during the maximal incremental exercise test (296 ± 37 W). Data are presented as group mean ± SEM. ^* P < 0.05 vs control.
