Abstract

Physical exercise during adolescence affects brain functions for a long time, extending into adulthood. This study was aimed to examine the effect of curcumin supplementation on Brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) levels in the brain in adolescent rats subjected to weight-loaded forced swimming exercise. Female Sprague-Dawley rats at 6 weeks of age were randomly assigned to four groups: control, swimming exercised (SE), curcumin (CCM) and swimming exercised+curcumin (SE+CCM). After 1 week of adaptation training, SE and SE+CCM groups were given weight-loaded swimming exercise 5 days a week for 4 weeks. Curcumin was administered to rats in CCM SE+CCM groups via intragastric gavage at a dose of 50 mg/kg/d for 5 weeks. Prefrontal cortex and hippocampus BDNF and VEGF levels, and immunoreactivities were evaluated. BDNF levels of the SE group were significantly lower than the control and SE+CCM groups in the prefrontal cortex. VEGF levels of the SE group were significantly lower than the CCM and SE+CCM groups in the prefrontal cortex. VEGF values of the control group was increased compared to the SE and SE+CCM groups in the hippocampus. BDNF and VEGF immunoreactivities of the SE group were significantly lower than the control, CCM and SE+CCM groups. Our study show that curcumin supplementation reduces the inhibitory effect of exhaustive swimming exercise on the neurotrophic factors in the brain. The underlining mechanism of the effect of curcumin is related to BDNF and VEGF levels.
