The effects of a single bout of moderate-intensity aerobic exercise on visuomotor adaptation and its savings.

Performing exercise before or after motor skill learning is thought to have a positive impact on acquisition and retention of motor memories stored in our nervous system. It has been shown that performing 25 min of moderate-intensity aerobic exercise prior to visuomotor adaptation can enhance both visuomotor adaptation and its retention compared to 25 min of rest before the adaptation. To determine whether a single bout of aerobic exercise could actually facilitate the formation of a neural representation associated with a novel visuomotor condition, we examined aftereffects and savings associated with a visuomotor adaptation task following either an exercise or a rest condition.

The nature of savings associated with a visuomotor adaptation task that involves one arm or both arms.

The nature of savings in visuomotor adaptation is typically studied using a paradigm in which one arm experiences multiple conditions such as adaptation, washout and readaptation. It has seldom been studied, however, using a paradigm that involves both arms. Here, we examined the effect of (1) using different arms and (2) the availability of visual feedback during a washout session following visuomotor adaptation on savings.
