مقایسه تأثیر 8 هفته تمرین هوازی و تمرین مقاومتی بر سطح عامل نوروتروفیک مشتق از مغز سرم مردان سالمند

Objectives: The goal of this study was to compare the effect of 8 weeks aerobic exercise with resistance&nbsp;training on Brain-derived neurotrophic factor level of old men. Methods & Materials: In this semi-experimental study, a total of 30 elderly men were selected from&nbsp;worldly-wise club of Broujen City, Iran and randomly divided into 3 groups of aerobic training, resistance&nbsp;training, and control (each 10 people). All participants filled the health questionnaire and testimonial.&nbsp;Then, the balance tests and fasting blood was taken. The aerobic and resistance training group trained&nbsp;for 8 weeks, 3 sessions per week, 1 to 1.5 hours in each session. The aerobic training was with 40% to&nbsp;70% of maximum heart rate and the resistance training was with 45% to 65% of one RM. During of this&nbsp;time, the control group did no training. After 8 weeks, the balance test was administered and blood&nbsp;samples were taken. Results: Findings were analyzed with test variance analyzing at 0.05. The results showed there was a significant&nbsp;difference between aerobic and resistance training regarding brain-derived neurotrophic factor&nbsp;level (P<0.05). Also, comparison of the 2 kinds of training did not show significant difference in static and&nbsp;dynamic balance (P>0.05). Conclusion: The results show that both aerobic exercise and resistance increase serum brain-derived neurotrophic&nbsp;factor levels.
