Fig. 1 Comparison of average total path (ATP), time (ATT) and swimming speed (ASS) within 7 days of trial in controls and runners. Rats were trained over 7 days to find the hidden platform in the Morris Water Maze. Different alphabet above the columns indicated significant difference between combinations at 5% probability level. Data expressed as mean±S.E.M. C6: Six months old control group; T6: 6 months old test group; C9: 9 months old control group; T9: 9 months old test group; C12: 12 months old control group; T12: 12 months old test group.

Fig. 2 Water maze learning in control and runners trained with four trials per day. Different alphabet above the points indicates significant difference between combinations at 5% probability level in ATT, ATP and 1% probability level in ASS. Data expressed as mean±S.E.M.
