Background: The aim of this study was to investigate the effect of 12 weeks of high intensity training on IL-
6, GLP-1 and lipid profiles in type 2 diabetic patients

Methods: 80 participants (40-50 years old) volunteered to participate in the study and divided into eight groups (four groups of severe periodic exercises and four uncontrolled control groups). Blood samples were collected and analyzed for measuring IL-6, GLP-1, lipid profile and glycemic index before and after weeks 4, 8 and after the training program.
Results: After 12 weeks of training, the effect of time and interaction between time × group on GLP-1 and IL-6 variables was statistically significant. Also, there was a significant difference between groups based on 12 weeks of training in these indices. Lipid profile was significantly improved in type 2 diabetic and glycemic control in obese and non-diabetic groups that had 12 weeks of high intensity interval training.

Conclusion: Overall, high intensity interval training, through changes in various mechanisms, lead to improvement in lipid and glycemic disorders, inflammation and appetite in obese people with type 2 diabetes. Hence, according to the findings of the study, researchers suggest that performing high intensity interval training can lead to significant improvements in obese subjects (with and without type 2 diabetes).

Background: Inflammation is one of the main causes of obesity and type 2 diabetes due to obesity and can increase metabolic disorders. Because exercise and diet are effective in reducing inflammation, Hence, Present Study Examined the Effects Of 24 Weeks Interventions On IL-6 Index Changes in Obesity Type 2 Diabetic Men: Influenced by HIIT And Diet Regimes
Methods: In this study, 70 men (Obese Type 2 Diabetic Patients) were randomly assigned into 7 groups (4 groups in different diet plus HIIT intervention and 3 groups only in different diet) that involved adherence to a 1,200 kcal/day for 1 week until 1,900 kcal/d diet for 24 weeks while participating in a supervised HIIT (12 week) followed with 4 weeks primarily diet regimes. Diet regimes consist of standard diet (50% CHO, 32% fat), low carbohydrate diet (25% CHO, 57% fat; 70% of 57% fat was unsaturated fat), low fat diet (67% CHO, 15% fat) and high fat (25% CHO, 57% fat; 50% of 57% fat was saturates fat), while protein was 18% for all groups. Anthropometrics and physiologies parameters, Body composition and fasting blood samples were obtained at 0, 4, 8, 14, 20 and 24 weeks. Data were analyzed by repeated measures analysis, one-way ANOVA test. Data are presented as mean±SD changes from baseline.
Results: results indicated that between differences times wasn’t show significant different (F (5,315) =3.66; P=0.002; η2=0.055).  also results demonstrated that within groups changes interactions don’t show significant different (F (5,315) =1.61; P=0.025; η2=0.133). This results also revelated that maximum increase and decrease of IL-6 was in high fat diet (28.09±19.80) and low CHO+HIIT (-28.89±25.13) after 24 weeks interventions. maximum increase and decrease of IL-6 was in high fat diet (26.74±25.33) and low fat +HIIT (-32.11±29.17) After 12 weeks HIIT + diet interventions.
Conclusion: Results support contentions that different diet regimes and exercise were selectively affects Pro Inflammatory markers and that changes in low CHO and low fat plus HIIT and low CHO meals plus with HIIE may be benefit for obese type 2 diabetic patients

Results: After 12 weeks of combined, aerobic, high intensity and resistance training, anti-inflammatory indices (adiponectin and SFRP5) showed a significant increase compared to the baseline (before starting the training program) (P < 0.05). Regarding pro-inflammatory and anti-inflammatory indicators (IL-6, TNF-α, resistin and leptin), a significant decrease was observed in all groups after 12 weeks of training program (P < 0.05). In this study, a significant improvement in weight loss and blood glucose was observed after 12 weeks of exercise program in all 4 exercise groups (P < 0.05). In the second part of the findings (non-training or durability of training effect), it was resistance training that showed a lower percentage decrease (P < 0.05) in anti-inflammatory indices and an increase in pro-inflammatory and inflammatory indices after 12 weeks of non-training, which showed the durability It shows more recovery in obese type 2 diabetic patients (P < 0.05).
Conclusion: The findings of the research showed that high-intensity interval training after 12 weeks can cause a greater effect on inflammatory, pro-inflammatory and anti-inflammatory indicators compared to aerobic, combined and resistance training. But this is the resistance exercise that caused the reduction in inflammatory, pro-inflammatory indicators and increase in anti-inflammatory indicators in obese type 2 diabetic patients to be more permanent.
