Influence of increased motor activity on learning and memory in albino rats.

The experiment has been carried out with 20 male Wistar rats with initial age 30 +/- 5 days, equally divided in two groups: controls and motor-loaded rats. The experimental animals ran five days a week on a treadmill covering 60,540 m for 133 training sessions. Afterwards using a multi-chamber semi-automated labyrinth it was found that systematic and dosed motor loading leads to significant improvement of both learning and retention. The results obtained are examined as a consequence of the biochemical and morphofunctional changes developing in the central nervous system under the effect of prolonged motor activity.
