Millions of people worldwide have Alzheimer's disease, and with the disproportionate growth of the elderly population, the disease, which is the most common form of dementia among the elderly, is becoming a public health crisis. This study aimed to investigate the effect of endurance training before and after Alzheimer's induction on some neuroplasticity-related factors in the hippocampus of male Wistar rats. Before inducing Alzheimer's disease, 32 8-week-old male rats weighing an average of 250 g were randomly allocated into two groups: rest (16 heads) and exercise (16 heads). Each group was divided into two subgroups after four weeks (the first and second weeks at a speed of 10 meters per minute in two 15-minute shifts, the third week at a speed of 15 meters per minute in three 15-minute shifts, and the fourth week at a speed of 15 meters per minute in four 15-minute shifts with 5-minute intervals).1. amyloid beta injection and 2. without injection. After 72 hours, the animals were killed and their hippocampus was removed for examination. Real Time PCR measured BDNF, PKG, and cGMP gene expression.Data were analyzed by one-way analysis of variance and Tukey post hoc test at the significant level of p <0.05. The results showed that the levels of BDNF, PKG and cGMP in the exercise group were significantly higher than the rest group in the stage after Alzheimer's induction (p = 0.001). According to the results, it seems that aerobic exercise can help improve neuroplasticity in the hippocampus of Alzheimer's mice.
