A Comparative Study on the Effect of Endurance and Resistance Training on Angiogenesis Factors in Elderly Diabetic Patients

Background & Aims: The main long-term problems of chronic diabetes are cardiovascular complications classified as micro/macro-vascular complications. The consequences for patients include cardiovascular diseases, nephropathy, retinopathy, and so on. Due to the effect of exercise on tissue blood flow distribution and the different nature of the two types of resistance and aerobic exercises, this study aimed to compare the effect of aerobic and resistance trainings on angiostatinlevel of men with type ۲ diabetes. Methods: A total of ۲۶ men with type ۲ diabetes (mean age: ۶۴.۵۶±۱۱.۳ years, mean weight: ۶۸.۵۰±۵.۴۲ kg, mean height: ۱۵۰±۴۳.۱۶۲ cm and ۱۰- year history of diabetes) referred to Kerman Diabetes Center were purposefully selected and randomly divided into two groups of aerobic and resistance trainings. After being familiarized with the research protocol, subjects did resistance exercises based on a percentage of the maximal strength (۱ RM) and the endurance exercise with the intensity of percentage of maximum consumed oxygen three sessions in week (۴۰-۶۰ minutes each session) and for ۱۲ weeks. Blood samples before and ۲۴ hours after the last training session were collected. For comparison within the groups, independent t- test and for comparison between groups, repeated measure two-way ANOVA were used. Results: Serum anigiostatin level and VEGFR showed no significant difference between the two groups (P=۰.۱۱۶, P=۰.۲۱۸ respectively), but groups showed significant increase in serum angiostatinlevel and VEGFR after the intervention (P<۰.۰۵). Conclusion: The results showed that twelve weeks of resistance and aerobic exercises can improve of men with type ۲ diabetes and increases their anigiostatin level but non significantly.
