Background: The neuroprotective effects of aerobic exercise and the enriched environment have been demonstrated, but the acute effects of aerobic exercise in the enriched environment have not been studied. Therefore, the purpose of this study was to investigate the effect of aerobic exercise in the enriched environment on serum levels of brain-derived neurotrophic factor (BDNF), triglyceride, and glucose in active elderly men.
Materials and methods: Ten active elderly men (age: 60.30±3.83 years) voluntarily participated in this semi-experimental study. The subjects ran one-hour with intensity of 12-15 in Borg scale, one session in an ordinary environment and one session in an enriched environment, two weeks apart in a randomized cross-over design. Five minutes before and after the training, the blood sample was taken for measurement of the changes in serum levels of BDNF, triglyceride, and glucose.
Results: The results of paired samples t-test showed that in both environments, the serum levels of BDNF increased significantly (p=0.001). However, in the enriched environment, serum levels of triglyceride also decreased significantly (p=0.011). Also, the results of the covariance test showed no significant difference between the levels of all variables in the two environments. On the other hand, the percentage of changes in all variables was higher in the enriched environment.
Conclusion: One hour of running with moderate intensity significantly increased serum levels of BDNF in active elderly men. But, only aerobic exercises in the enriched environment significantly reduce levels of triglyceride. Overall, running in the enriched environment may have a greater impact on BDNF, triglycerides, and glucose. |
