Human neuromuscular adaptations that accompany changes in activity.

Neuromuscular adaptations probably occur at all levels of the motor pathway, following changes in muscular activity. Adaptations have been mostly investigated in muscle fibers after heavy-resistance and endurance training. In strength training the rapid improvement is due to poorly understood neural factors, with muscle fiber hypertrophy occurring rather later; fiber hyperplasia is probably unimportant. In contrast to other mammals, muscle …
