The purpose of the present study was to examine the effect of eight weeks moderate-intensity endurance training on hypocampic brain-derived neurotrophic factor (BDNF) and tyrosine kinase B (TrkB) receptor gene expression in the rats with hippocampal degeneration model. In this experiment, twenty four mature Sprague-dawley male rats were subjected to Alzheimer’s disease through intraperitoneally injection of 8 mg/kg Trimethytin (TMT) and then were divided into (1) Alzheimer-infected control group, (2) endurance training, and (3) sham to study the impact of the disease on the variables. Sixteen healthy rats were assigned to the control group that eight rats sacrifice at first week and eight rats sacrifice at last week. The rats in the endurance training group ran on a rat treadmill with the speed of 15 to 20 meters per minute for 15 to 30 minutes in each session, 3 times a week for 8 weeks. To analyze the results of the tests, one-way ANOVA and Tukey post hoc test were run using SPSS The results revealed that induction of Alzheimer’s disease by TMT decreases the BDNF and TrkB receptor gene expression in rats. The results, also indicated that there were no significant differences in hypocampic BDNF and TrkB receptor gene expression between endurance training group and sham group. According to the study results, it seems that endurance training with specific intensity and duration utilized in this study had not significant effect on changes of hypocampic BDNF and TrkB receptor gene expression in the rats with hippocampal degeneration model.
