AAGAARD, P. Training-induced changes in neural functions. Exerc. Sport Sci. Rev., Vol. 31, No. 2, pp. 61–67, 2003. Adaptive changes can occur in the nervous system in response to training. Electromyography studies have indicated adaptation mechanisms that may contribute to an increased efferent neuronal outflow with training, including increases in maximal firing frequency, increased excitability and decreased presynaptic inhibition of spinal motor neurons, and downregulation of inhibitory pathways.
