Effects of aerobic exercise training on peripheral brain-derived neurotrophic factor and eotaxin-1 levels in obese young men

Abstract

[Purpose] The aim of the present study was to investigate the effects of aerobic exercise training on the levels of peripheral brain-derived neurotrophic factor and eotaxin-1 in obese young men. [Subjects and Methods] The subjects included sixteen obese young men with a body mass index greater than 25 kg/m2. They were randomly divided between control and exercise groups (n = 8 in each group). The exercise group performed treadmill exercise for 40 min, 3 times a week for 8 weeks at the intensity of 70% heart rate reserve. Blood collection was performed to examine the levels of serum glucose, plasma malonaldehyde, serum brain-derived neurotrophic factor, and plasma eotaxin-1 before and after the intervention (aerobic exercise training). [Results] Following the intervention, serum BDNF levels were significantly higher, while serum glucose, plasma MDA, and plasma eotaxin-1 levels were significantly lower than those prior to the intervention in the exercise group. [Conclusion] Aerobic exercise training can induce neurogenesis in obese individuals by increasing the levels of brain-derived neurotrophic factor and reducing the levels of eotaxin-1. Alleviation of oxidative stress is possibly responsible for such changes.
