It is well established that a functional reorganization takes place in the central nervous system as a consequence of physical activity or inactivity. Moreover, such reorganization is context-dependent and thus very sensitive to a variety of factors such as the type of physical activity and the environment surrounding the activity. In this article, we will review the current literature as well as introduce recent results that we have obtained utilizing behavioral and electrophysiological methodologies. Our results describe the specificity and nature of activity related neuronal reorganization and have important implications for construction of training regimens designed to improve physical performance.
