Fatigue-related Feedback from Calf Muscles Impairs Knee Extensor Voluntary Activation

Conclusions Maintained group III/IV afferent feedback from the fatigued plantarflexor muscles reduced maximal force and voluntary activation of the unfatigued knee extensors, suggesting that afferents from the calf act centrally to inhibit the ability to drive the motoneurones of the knee extensors.
