The effect of regular Taekwondo exercise on Brain-derived neurotrophic factor and Stroop test in undergraduate student.

PURPOSE: The purpose of this study was to investigate the effect of Taekwondo exercise on Brain-derived neurotrophic factor and the Stroop test in undergraduate students. METHODS: Fourteen male subjects participated in this study. They were separated into a Control group (N = 7) and an Exercise group (N = 7). Subjects participated in Taekwondo exercise training for 8 weeks. They underwent to Taekwondo exercise training for 85 minutes per day, 5 times a week at RPE of 11~15. The taekwondo exercise training comprised an aerobic exercise (20min) mode and a dynamic exercise (65min) mode. All data were analyzed by repeated measures two-way ANOVA. RESULTS: There were no significant differences in the physical characteristics of the subjects. Although weight and BMI showed a tendency to decreased in the exercise group (EG). Also, neurotrophic factors (BDNF, NGF, IGF-1) were not significantly different after 8 weeks in the two groups. However, BDNF and IGF-1 showed a tendency to increase in the exercise group (EG). Finally, the Stroop test (word, color) results were significantly different(p < .05) in the exercise group (EG). CONCLUSION: These finding suggest that 8 weeks of regular Taekwondo exercise training may increase cognitive functions (Stroop test). However the training did not statistically affect neurotrophic factors (BDNF, NGF, IGF-1) in undergraduate students.
