The aim of this study was to compare the effect of endurance exercise on the level of focus of attention and brain derived neurotrophic factor(BDNF) in non-athlete male and female students and to investigate the relationship between variations in these factors. 30 non-athlete students (mean age 24.1+1.6 years) were assigned to 4 groups: males, females, male control and female control based on the Stroop pretest. After blood samples were collected, they continued their endurance exercises for 5 weeks, 3 sessions per week, 40 min. each session with the intensity of 70-85% maximum heart rate based on the endurance exercise protocol. Results showed that endurance exercise significantly increased BDNF in both male and females) P<0.05), but the time of response to Stroop test significantly decreased only in male group) P<0.05). In addition, the results showed no significant differences between male and female groups in the effectiveness of endurance exercise on the time of response to Stroop test (P>0.05), but level of BDNF was significantly more in female group than the male group (P<0.05). The correlation between variations of response time to Stroop test and level of BDNF was not statistically significant in both male and female groups (P>0.05). Finally, according to these findings, it seems that endurance exercise can increase BDNF level and improve focus, but there are possible differences between males and females that need further research.
