Introduction: Diabetes is one of the most important health problems in the world. The aim of this study was to evaluate the response of a session of resistance exercise with blood flow restriction (REBFR) to hemodynamic and hematological changes in type 2 diabetic patients.Materials and Methods: Fifteen patients with type 2 diabetes performed knee flexion and extension of the resistance exercise with and without BFR in two sessions with intensity of 20% and 80% 1RM, respectively. Hemodynamic and hematological changes were measured at before, immediately and 30 minutes after exercise. Repeated analysis of variance was used to evaluate the effect of the intervention on quantitative factors.Results: The mean values of systolic and diastolic blood pressure and heart rate values in both training sessions were not significantly different (P <0.05). The results showed that there was no significant difference between WBC, RBC, HCT, Hb, MCH, MCHC, MCV and PV indices between resistance exercise sessions with and without BFR (P <0.05). According to the findings, the amount of RBC and Hb increased significantly immediately after REBFR (P <0.05), which returned to resting levels after 30 minutes of recovery.Conclusion: Low-intensity REBFR due to no significant change in hemodynamic, hematological and platelet parameters can be an effective and low-cost mechanism in preventing cardiovascular disease in patients with type 2 diabetes and as a Non-pharmacological treatment system and alternative to high-intensity resistance exercise to prevent muscle atrophy, especially in clinical populations, especially diabetics.

Background and Purpose: Mechanical tension induced by resistance exercise can stimulate tension-sensitive cytoskeletal proteins. Also, resistance exercise can induce inflammatory factors. Therefore, the aim of this study was to investigate the changes of inflammatory and hypertrophic markers and their association with a single bout of resistance exercise in male rats.
Materials and Methods: Twelve male Wistar rats, three months of age, were randomly assigned into control and experimental groups. Resistance exercise protocol (to climb up a one-meter ladder, 3 sets, 10 repetitions in each set, at 50%, 75% and 100% of their own body weight) was performed. The control group did not perform any exercise activity. Twelve hours after the last session of exercise, rats (both control and experimental) were anesthetized with a mixture of ketamine/xylazine. Blood samples were taken directly from the heart; their Soleus muscles were extracted. Vinculin levels in muscle tissue after homogenation and IL-17 levels in sera were measured using ELISA method. Creatine kinase levels were measured by enzymatic colorimetric methods. Independent t-test and Pearson correlation coefficient were used. A significance level of α= 0.05 was considered.
Results: There was no significant diferences between control and experimental groups in vinculin, IL-17 and creatine kinase levels (p>0.05). Nevertheless, there was a significant negative corrolation between vinculin and IL-17 (r=-0.93, p=0.01).
Conclusion: A single bout of resistance training can lead to a change in vinculin, IL-17 and creatine kinase levels. Interaction between inflammatory and hypertrophic markers (especially vinculin and IL-17) probably has a role in adaptations induced by resistance training.

Background and purpose: Every type of exercises could lead to different immune responses in human body. The purpose of this study was to compare the acute effects of endurance exercises (EE), resistance exercises (RE) and concurrent exercises (CE) on serum interleukin-17 (IL-17) concentrations and number of lymphocytes, monocytes, and neutrophils in active men.
Materials and Methods: Twenty healthy young and active men (Age: 21.69±2.66; BMI: 21.92±1.89; Fat%: 14.49±3.05) voluntarily participated in this study and randomly were assigned into three groups: EE (n=7), RE (n=6) and CE (n=7). Subjects performed special exercise protocol for each group consisted of 45 minute. IL-17 serum concentrations were measured by ELISA method and so numbers of some classes of leukocytes were computed (Pre, immediate and 1 hour post-exercises). Data were analyzed using Repeated-Measures analysis of variance, One-Way ANOVA and Tukey post-hoc and Paird T-test at the significance level of α=0.05
Results: Changes in the serum levels of interleukin-17 was significantly different between groups immediately after exercise and 1 h post-exercise. Also, lymphocytes and neutrophils numbers 1 h post-exercise and monocytes and neutrophils numbers, 1 h post-exercise compared to basal levels were significantly different between three exercise groups, respectively (p

Background: The risk of developing diabetes and cardiovascular disease in the elderly, obese and sedentary population is high. Exercise can improve metabolic disorders associated with these diseases. The aim of this study was to investigate the effect of eight weeks resistance exercises on C-reactive protein (CRP), Interleukin-6 (IL-6) and lipid biomarkers in sedentary middle-aged men.
Materials and Methods: This quasi-experimental study was conducted in 2012 in the city of Sari. In this study, 24 subjects were randomly divided into two groups; experimental and control group (each group 12). The resistance exercise program was performed for eight weeks, 3 times a week, 90 minutes per session, with intensity of 60-70 one repetition maximum. Blood samples were collected before and after the exercise intervention. Data were analyzed using SPSS version 15 and P
