Respiratory Muscle Fatigue Alters Cycling Performance and Locomotor Muscle Fatigue

imagePurpose This study aimed to determine if preexisting respiratory muscle fatigue (RMF) alters motoneuronal output, locomotor muscle fatigue, and cycling performance. Methods Eight trained male cyclists performed 5-km cycling time trials after a resistive breathing task that induced RMF and under control conditions (CON). Motoneuronal output was estimated using vastus lateralis surface electromyography, and locomotor muscle fatigue was quantified as the change in potentiated quadriceps twitch force from preexercise to postexercise. Results Time to complete the time trial was 1.9% ± 0.9% longer in RMF compared with CON (P
