Adaptations in biceps brachii motor unit activity after repeated bouts of eccentric exercise in elbow flexor muscles.

abstract：:Adaptation of movement may be driven by the difference between planned and actual motor performance, or the difference between expected and actual sensory consequences of movement. To identify how the nervous system differentially uses these signals, we asked: does motor adaptation occur when movement errors are irrel...
