Adipokines dysregulation plays important role in the type 2 diabetes (T2D) pathogenesis. However, exercise training can be effective in improving the glycemic control in T2D patients by modulating the adipokines levels. In the present research, the effects of 12 weeks of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on the serum levels of progranulin and MCP-1 in type2 diabetic women have been investigated.

36 qualified and volunteer women with T2D were randomly assigned in the three groups including control, MICT and HIIT groups. Both HIIT (90 percent of maximum heart rate) and MICT (60 to 70 percent of maximum heart rate) protocols were conducted on treadmill for 12 weeks. Blood samples were collected in pre and post-test stages. Between groups difference were determined by analysis of covariance test and significant level was P<0.05.

The present study findings indicated that both HIIT (p<0.001) and MICT (p=0.014) protocols cause significant decrease in the MCP-1 levels. However, the progranulin reduction compared to the control group was significant only in the HIIT group (p<0.001) and MICT does not have significant effect on the progranulin levels (p=0.077). Decrease in body fat percentage and insulin resistance was also significant for both HIIT and MICT protocols compared to the control group (p<0.001).

Both HIIT and MICT exercise trainings are effective for modulating the adipokines levels in the T2D patients. However, the effectiveness of HIIT was greater for reduction of progranulin levels compared to the MICT group, which indicates the importance of paying more attention to HIIT in the management of T2D.

Progranulin (PGRN) has been recently introduced as a new indicator of chronic inflammatory response in type 2 diabetes. The present study aimed to investigate the effect of combined training on serum levels of progranulin, glycosylated hemoglobin (HbA1c), and insulin resistance in overweight and obese women with type 2 diabetes.

A total of 36 women were divided into three groups: control, combined exercise 1 (combined aerobic-resistance training), and combined exercise 2 (combined resistance-aerobic exercise training, including aerobic exercises with an intensity of 80% to 95% of maximum heart rate and resistance training with an intensity of 60% to 85% of one-repetition maximum). Anthropometric indices, muscle strength, aerobic capacity, variations of PGRN, HbA1c, and insulin resistance were also measured before and after training. To analyze the data, repeated measures analysis of variance (ANOVA) was used, and the level of statistical significance was set at <0.05.

The main and interaction effects of training on PGRN, HbA1c, insulin resistance, muscle strength, and aerobic capacity were significant over time (P=0.001). Despite improvements in PGRN, HbA1c, insulin resistance, lower-body muscle strength, and aerobic capacity in the training groups, no significant difference was observed between the combined training groups and the control group (P<0.05). However, the upper-body muscle strength significantly increased in both combined training groups, compared to the control group (P=0.001).

The use of combined exercise training in different orders for 12 weeks did not have any significant effects on the PGRN, HbAc1, insulin resistance, and functional factors.

Poly Cystic Ovary Syndrome (PCOS) is the most commonly encountered endocrine gland disease affecting 5-10 present of women at their reproductive age. This syndrome is associated with type 2 diabetes، dyslipidemia، and obesity. Progranulin and relaxin are adipokins that are related with carbohydrate and lipid metabolism. Due to limited data about progranulin and relaxin plasma levels´ in women with PCOS and normal BMI، this study was conducted. This study is a cross-sectional. During the study 39 women with PCOS and BMI< 25 on the basis of Rotterdam criteria were chosen as the patient group and 38 healthy women were selected as the control group. The concentration of progranulin and relaxin were measured by ELISA technique. The difference in Plasma concentration of progranulin and relaxin، and also some of the biochemical parameters in the patient group versus to the control group was not significant، but there was significant difference in the concentrations of VLDL، triglyceride (p=0. 046)، insulin (p=0. 016)، HOMA-IR (p=0. 015)، testosterone (p=0. 01)، and DHEAS (p=0. 034) in the patients group compared to the control group. In this study، the difference in Plasma concentration of progranulin and relaxin in the patient group compared to the control group was not significant. It could be inferred that lack of change in plasma level of progranulin and relaxin in women with PCOS is related to BMI<25 and FBS<110. Moreoverestosterones، insulin، DHEAS and HOMA-IR changes could be better predictors of PCOS and its associated diabetes.
