Consumption of Ginkgo biloba Extract and Swimming Training on NMDA and BDNF Plasma in Untrained Girls

Ginko biloba stimulate blood circulation to the brain. As a result of insufficiency to improve blood flow to the brain. The aim of this study was to investigate the effect of eight weeks endurance training swimming on BDNF and NMDA levels with Ginkgo biloba extract young girls untrained. 40 healthy females aged 27-22 girls as subjects of this study were selected and randomly divided into four groups of 10 people (1-swim training with Ginkgo biloba extract (SG), 2- swimming training(S), 3- Ginkgo biloba extract (G) and 4- control group (C)).

The experimental group consisted of eight-week training program three times a week, with an intensity of 60-75% of maximum heart rate were performed. Blood samples from subjects 24 hours before and after the test, was used for measure the levels of NMDA and BDNF. Results with the t-test and one-way analysis of variance were analyzed and significant levels of p ≤0.05 determined. The results showed that levels of NMDA in SG and G group had significant increase. However, The significant increase in the levels of BDNF in SG, G and S were observed. The present study endurance training and Ginkgo biloba consumption was effective in decrease anxiety and improve memory that related to flavonoid and antioxidant activity of this plant.
