Background: The purpose of this study is to the comparison of the effect of 12 weeks of sprint training and concurrent aerobic and strength training on high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) and insulin resistance in women with diabetes mellitus (T2DM)

Methods: 52 overweight female type 2 diabetic patients (age; 45-60 years old and fasting blood glucose ≥ 126 mg/dl (7.0 mmol/l)) were assessed for eligibility. Participants were assigned to intense interval training group (N=17), concurrent resistance- endurance training group (N=17) and control group (N=18). The combined strength-endurance group did 12 weeks, three sessions per week endurance training with 60 % of maximal heart rate and two session resistance training with 70 % 1-RM. Intense interval training group did three session/week of 4-10 repetition of all out 30s Wingate on ergometer were included 10 weeks of concurrent resistance- endurance training and intense interval training.

Results: The results showed that following sprint training, there were significant changes in hs-CRP (p<0.001), but it wasn’t significant following concurrent training (p=0.062). According to results, TNF-α change were not significant in intense sprint (p=0.11) and concurrent training (p=0.23). Differences were not significant for the fasting blood glucose in the intense interval training groups (p=0.000). Serum insulin levels showed significant increases in the SIT (p<0.000) and concurrent training (p=0.000) significantly. The data showed significant differences in insulin resistance index (HOMA-IR) in intense interval training (p=0.000) and concurrent resistance- endurance training (p=0.008). ANCOVA test showed no significant difference in fasting blood glucose concentrations (P=0.171).

Conclusion: Intense sprint training compare to concurrent strength-endurance training can have better inflammatory status for patients with type 2diabete.

visfatin secreted by various factors, including cytokines such as TNF-α and IL-6 is affected. The purpose of this study was to evaluate the effect of eight weeks of combined training (resistance circular - aerobic) visfatin concentration, IL-6 and TNF-α in obese men with type II diabetes.
Methods: The population of the research was all men with diabetes type II in District 2 of Ahwaz. Twenty four patients with diabetes type II, aged 40-55 years and fasting blood glucose lower than 200 mg /dl were selected by purposive sampling. First, the anthropometric variables and body composition were measured, then subjects were randomly divided into two groups (experimental, n=12 and control, n=12). Combined exercise training was done for 8 weeks (5 days/week, 30 to 50 minutes) for experimental group. To analyze the changes in the covariance analysis and dependent t test measured variables at a significance level of p≤05.
Result: After eight-week combined exercise training, fasting blood glucose and plasma visfatin significantly decreased p≤05. But no significant changes were observed in the levels of IL-6 and TNF-α p≥05. Also, the inverse relationship between plasma visfatin with IL-6 and TNF-α was observed (P≤ 0.05).
Conclusion: Eight weeks of combined training despite a positive effect on plasma visfatin, due to no significant changes in plasma IL-6 and TNF-α in patients with type 2 diabetes, it seems this type of exercise in reducing obesity and visceral fat and thereby reducing plasma visfatin is appropriate, but the potential change in IL-6 and TNF-α does.

Background: Inflammation plays an important role in the incidence and development of metabolic disorders and exercises along with dietary restrictions for weight loss. It has beneficial effects on reducing inflammatory markers, especially in type 2 diabetes. The purpose of this study was to evaluate the effect of combined exercise (resistance-aerobic) with and without diet restriction on weight loss on some inflammatory markers (CRP, TNF-α and ICAM-1) in elderly men with type 2 diabetes.
Methods: 42 elderly men with type 2 diabetes (age: 67.6 ± 2.2, weight: 85.2 ± 7.4, BMI: 28.2 ± 0.2) after homogenization based on serum levels Glucose and mass index were randomly assigned to one of 3 groups: Combined exercise (15), combined exercise with weight loss diet (14), and weight loss diet alone (n = 13). The combined exercise program included aerobic training with 50-70 percent of reserved heartrate and resistance training included chest press, cable pull-down, machine leg extention and machine lying leg curl on 3 sessions per week for 12 weeks.

Results: After 12 weeks of intervention, there was a significant decrease in serum inflammatory markers levels (CRP, ICAM-1 and TNF-α) in the post-test compared to the pre-test in all three groups (P<0.001). However, bonferroni post-hoc analysis showed that combined exercise with diet compared to combined exercise and dietary restriction alone had more effects on reducing CRP, ICAM-1 and TNF-α (P<0.001). In addition, reduction of ICAM-1 (P<0.001) and TNF-α (P<0.001) after combined exercise compared to dietary restriction and CRP reduction after dietary restriction than combined exercise was significantly higher (P<0.001).

Conclusion: It suggested that in elderly type 2 diabetic patients, caloric restriction-induced weight loss with combine exercise is more appropriate for modulating of endothelial biomarkers and Inflammation dysfunctional levels than resisted exercise training or aerobic training alone.
