Figure 1. The path lengths in Morris water maze testing. The treadmill running caused a significant enhancement learning and memory in rats of Group A compared with the controls (C). Panel (a) mean (± SEM) path length to reach the hidden platform in total 8 days have been calculated in the four rat groups, A and B groups showed significant decreases compared to the control (C) group (* p < 0.05, **p < 0.001). Panel (b) shows that the path length decreased in each group especially during the first days of the Morris water maze testing. When compared with the controls (C) difference in the A group was clear already immediately i.e. it was significant in days 1, 2, 7, 8 (* p < 0.05) i.e. the chronic and continuing treadmill exercise promoted significantly this kind of learning.
