Effect of Swimming Training on Spatial Memory of Maternal Deprived Infants: Inducing Stress by Six Hours Separation per Day

Abstract

and in to The results of the analysis of variance test showed that the blood glucose in the group of rats that were separated from their was significantly higher, compared to the control group (P=0.045), indicating that stress was successfully induced in these rats. Moreover, the results of the multivariate analysis of the variance test showed that although stress had no significant impact on spatial learning, the results of the exploration test showed a significant decrease in the percentage of entering the target quadrant (P=0.05) and the time spent in the target quadrant in the group separated from mother (P=0.029), compared to the control group. Therefore, spatial memory was degraded due to stress in the group of rats that were separated from their mother, compared to the other groups. However, swimming training in the group of rats that was separated from the mother could neutralize the destructive effects of stress on spatial memory and the percentage of entering the target quadrant (P=0.02) as well as the time spent in the target quadrant (P=0.05). Discussion & Conclusion: The results showed that although stress did not have a negative impact on spatial learning, it had a destructive impact on memory. On the other hand, swimming training as a treatment method could largely neutralize the negative effects of stress and improve memory.
