Introduction: Various serum factors in response to aerobic exercise improve cognitive function in healthy individuals, but the effect of aerobic exercise on their levels has not been studied. Therefore, the aim of the present study was to investigate the relative role of factors affecting memory and learning in response to aerobic exercise in triathlon male adolescents in Tuyserkan.
Materials and Methods: In this quasi-experimental study, 22 triathlon male adolescents (age: 17.60 ± 0.52 years, weight: 60.74 ± 4.96 kg, height: 175.60 ± 5.52 cm) voluntarily participated. Subjects performed 60 minutes of running with an intensity of 12-13 on the Borg scale (moderate intensity). Blood samples were taken from the subjects five minutes before and after training. Serum levels of BDNF, DCX and DBHB were measured by ELISA. To analyze the data, paired samples t-test was used and the level of significance was considered as p <0.05. Also, the percentage of changes were compared to pre-test.
Results: First, the results showed that serum levels of DCX (p = 0.0005), BDNF (p = 0.0005) and DBHB (p = 0.001) increased significantly compared to the pretest. Then, serum levels of BDNF (21.30%), DBHB (12.95%) and DCX (12.01%) had the highest increase compared to the pretest, respectively.
Conclusion: Neurotrophin/growth factor BDNF appears to be more responsive to aerobic exercise and may play a greater role in neuroprotection, improving memory, learning and cognitive function.
