The effect of exercise training in control of diabetes has been proved, but comparison of the effect of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on the protective mechanisms of heart tissue is still not well known. So, the aim of this study was to compare the effect of HIIT and MICT on the Sirtuin-3 (SIRT3) and Heat shock protein-70 (HSP70) gene expression in heart tissue of high-fat diet and diabetic rats.

eighteen male Sprague Dawley rats were fed with high-fat diet for three months. After that, diabetes was induced by injecting 30 mg/kg streptozotocin intra peritoneally. Then the rats were divided into 3 groups of 6 rats including, HIIT, MICT, and control. Also, 6 rats were considered to investigate the effect of high-fat diet and diabetes on research variables in the healthy control group. During 8 weeks training protocol, the HIIT group performed 6 training sessions in the first week to 12 training sessions in the last week training sessions with intensity of 80-85% of the maximum speed. MICT group was run 50 to 55% of the maximum running speed which lasted from 25 minutes in the first week to 50 minutes in the final week. Finally, SIRT3 and HSP70 gene expression values ​​were measured in heart tissue by qRT-PCR method. One-way analysis of variance (ANOVA) test was used to analyze the data (P<0.05).

SIRT3 gene expression levels in the HIIT and MICT groups were significantly higher than the control group (P=0.001) and HSP70 gene expression levels in the HIIT group were lower than the control group (P=0.01). In addition, no significant difference was observed in SIRT3 and HSP70 values ​​in HIIT and MICT training (P≤0.05).

It seems that HIIT and MICT play a role in improving mitochondrial function by increasing SIRT3 expression; However, considering the decrease in HSP70 levels following HIIT, it seems that more studies with the approach of cell damage following high-intensity training are needed.

The aim of this study was to investigate the effect of combined exercise on resting levels of pentraxin3 (PTX3) and serum amyloid A (SAA) in the plasma of men with type-2 diabetes.

Twenty oen-athlete men with type-2 diabetes were randomly divided into control and training groups. Combined training was performed for six weeks. Training including 25-35 minutes of aerobic exercise with an intensity of 55-75% of maximum heart rate and five resistance movements involving large muscles in the upper and lower body Includes five movements: chest press, army press, squat, dead lift, dumbbell rowing with an intensity of 55-75% of a maximum repetition with a frequency of three times a week with the periorizing of resistance training on aerobic training . The intensity of aerobic exercise was measured with heart rate monitor and the intensity of resistance training was measured every two weeks with a maximum repetition test. For data analysis, dependent and independent t-test was used at the significant level of P ≤ 0.05.

Examining the results of the study, it was found that the training contract reduced the SAA index (16.7%) and significantly changed it in the training group compared to the control group (P = 0.047 . However, there was no effect on resting SAA in the control group and a 2.2% increase in PTX3 in the training group was not significant (P = 0.474).

According to the results of the study and a significant decrease in inflammatory factor SAA and increase in PTX3, it can be concluded that six weeks of combined training affects the levels of these factors in men with type-2 diabetes and can probably reduce inflammation in these patients.

The metabolic benefits from each individual exercise session (in land vs. water condition) designated for trained diabetic patients remain to be evaluated. The aim of this study was to invesigate blood glucose, FFA, insulin, ANP and epinepherin levels during land vs. water cycling session and also following early post exercise recovery period.

This was a case-crossover study with time series method. Twelve postmenopausal diabetic women (age 66.76 ± 2.3 years), participated in three distinct test sessions with glucose tolerance test at the begining, at control, water and land exercise conditions, following participating in an interval training protocol (six weeks). Both aquatic and land exercise sessions were consisted of three sets of ten min cycling intervals at 40% of Vo2max. Blood sampling were done in five occasions each session including: pre exercise, immediately post exercise and also at 60th, 90th and 120 th min of post exercise period. The data were analyzed by factorial (3×5; three five phase series) ANOVA for repeated measurements using SPSS 21.

acute cycling in both water and land conditions decreased blood glucose (-37% and -39%), insulin (-20% and -17%) and FFAs (-61% and -55%), while serum ANP (169% and 52%) and epinephrine (43% and 82%) were up regulated (P < 0.05). Serum Insulin, FFAs and ANP levels were elevated also followingthe exercise cessation, with a synergic suppression of blood glucose and epinephrine levels (P < 0.05). All measured variables levesl were lower in water exercise session compared to land exercise (P < 0.05).

more beneficial metabolic effects could be provided with an individual training session performed by regularly exercising diabetic patients in water condioton, compared to land exercise and this trend was continued through two hours of recovery period. However; more investigations remain to be done because of the lack of similar evidence and study limitations.

Improper regulation of mitochondrial dynamics is associated with dysregulation of metabolism and can lead to metabolic diseases. This study aimed to investigate the effect of aerobic training on gene expression of Drp1 and Cyp1a1 and protein expression of CYP1A1 in soleus muscle of male diabetic rats. In this experimental study, 24 male Wistar rats were randomly divided into 3 groups: diabetes (D), control (Ct), and exercise + diabetes (ED) group. The diabetic model was induced in rats by STZ injection. The ED group performed an aerobic training protocol five times a week for eight weeks. After the end of the protocol, rat soleus muscle was extracted, and gene expression of Drp1 and Cyp1a1 RT-PCR and protein expression of CYP1A1 were measured using ELIZA. RNA was calculated using the formula 2^(-ΔΔCT)and then the data were analyzed using ANOVA. The results showed a significant difference between groups in the gene expression of Drp1 (P0.001) and Cyp1a1 (P=0.017), protein expression of CYP1A1 (P=0.028), and glucose (P0.001). Diabetes increases the gene expression of Drp1 and Cyp1a1 and the protein expression of CYP1A1 in skeletal muscle. However, exercise could only reduce gene expression of Drp1 (P=0.013). Diabetes leads to increased glucose, gene expression of Drp1 and Cyp1a1, and protein expression of CYP1A1 in skeletal muscle. But the exercise could prevent only increase of gene expression of Drp1.However, exercise could only reduce Drp1 expression (P=0.013). Diabetes leads to increased glucose, gene expression of Drp1 and Cyp1a1, and protein expression of CYP1A1 in skeletal muscle.

Aerobic training and berberine chloride both have antioxidant characteristics, therefore the present study aimed to evaluate the changes in lung tissue antioxidant enzymes after endurance training with the use of berberine chloride in diabetic vestibular rats. For this purpose, 40 adult male Wistar rats weighing approximately 200-250 g were randomly divided into 5 groups including healthy control ,diabetic control group (with STZ injection), diabetic experimental group+physical Exercise, diabetic experimental group + berberine Intake (50 mg/kg), diabetic experimental group+physical exercise+berberine Intake. 24 hours after the last exercise session, the animals were anesthetized with an intraperitoneal injection of Ketamine and lung tissue was harvested to measure the antioxidant enzyme activity of superoxide dismutase, catalase, and glutathione peroxidase. Paired t-test and ANOVA were used to analyze the data using SPSS software (version 22) with significant level α=0.05. The results showed that compare to control group, the level of CAT, SOD and GPX activity was significantly higher in all of the experimental groups (P=0.001). In comparison to the diabetic + training group and the diabetic + berbine group, the effects of intervention was significantly higher in the diabetic+training+berberine group. The final conclusion indicated that endurance training with berberin chloride consumption can cause a significant increase in the anti-oxidant enzyme activity in the lung tissue of diabetic rats.

Exercises and nutrition regimen have a major portion in the reduction of diabetes induced complications such as obesity, hypertension, hyperlipidemia and hyper- insulinemia. The Aim of the present study was to investigate the effect of swimming training with consuming Coriandrum Sativum extract on glycemic indices of diabetic rats.

32 Sprague- Dawley rats were randomly selected in this experimental research, and one week after the induction of diabetes, they were divided into four groups of 8 rats. These groups include: 1) swimming training, 2) Coriandrum Sativum, 3) swimming training with Coriandrum Sativum, and 4) control group. Groups 2 and 3 received 100 mg/kg Coriandrum Sativum peritoneally. Also, groups 1 and 3 swam for 4 weeks, five sessions per-week. -Each session lasted 30 minutes. In this study, Kolmogorov- Smirnov test, one way ANOVA and Tukey’s post- hoc tests were used for the statistical analysis of data (p≤0.05).

Swimming training, consumption of Coriandrum Sativum, and swimming training with Coriandrum Sativum had a significant effect on the reduction of fasting glucose and glycosylated hemoglobin (p≤0.05). In addition, Coriandrum Sativum and swimming training with Coriandrum Sativum had a significant effect on the reduction of insulin resistance (p≤0.05) . Furthermore, Coriandrum Sativum had more favorable effects on the reduction of fasting glucose compared with the swimming training (p≤0.05) and swimming training, Coriandrum Sativum, and swimming training with Coriandrum Sativum had no significant effect on the reduction of insulin (p≥0.05).

It seems that it is possible to use 4 weeks swimming training with Coriandrum Sativum in order to improve glycemic indices in diabetic rats.

Diabetes is a metabolic disease that causes cognitive disorders in addition to physical injuries. The role of physical activity and medical plants in improving memory and physical function has been reported, but the interactive effect of training at different temperatures with Cinnamon consumption has not been known yet. Therefore, the present study aimed to investigate the effect of swimming (S) training in water at 5 ° C (S5C) and 35 ° C (S35C) with cinnamon (Cin) consumption on avoidance memory, spatial memory and aerobic power of diabetic rats.

In this experimental study, 48 diabetic rats (55 mg/kg streptozotocin) were divided into 1) diabetic control (CD), 2) S5C, 3) S5C+Cin, 4) S35C, 5) S35C+Cin and 6) Cin groups. Eight rats were placed in the healthy control (HC) group to investigate the effects of diabetes induction on the research variables. Swimming trainings were performed at 2±5 ° C and 36±2 ° C for eight weeks, 3 days per week and 2-4 minutes in each session. The aqueous extract of cinnamon was 200 mg/kg/day dissolved in drinking water. 48 hours after the last training session, the research variables were measured.

S5C and S35C significantly caused the increase in step through latency (STL), percentage of alteration (PA) and aerobic power as well as decreased time spent in dark compartment (TDC) and repeat dark entrances (RDE) (P≤0.05). Cin caused a significant increase in PA and aerobic power as well as significant decrease in TDC (P≥0.05). Also, S5C+Cin and S35C+Cin significantly increased STL and PA and decreased TDC in diabetic rats (P≥0.05).

It seems that swimming training at different temperatures and consuming cinnamon have beneficial effects on the memory and learning of diabetic rats, but since Cin moderated the effects of training, further studies at the molecular- cellular level are recommended.

Diabetes is among the commonest chronic diseases, as well as the greatest health problem in all nations. The present research was designed and conducted to investigate the effectiveness of schema therapy on temperament and character dimensions, food craving among obese women with type 2 diabetes.

The present research was a semi-experimental, including pre-test and post-test with a control group. The current research’s statistical population included all the obese married women with type 2 diabetes registered as members of the diabetes association of Gonbad-e-Kavoos town in 2018 who had active cases in the association. The study sample included 40 patients who, based on inclusion-exclusion criteria, were selected by the available sampling method and were assigned into two experiment and control groups (20 subjects per group). Sessions Schema Therapy was held for ten 120-minute sessions for the participants of the experiment group. The research tool was the Temperament and Character dimensions and the Food Craving questionnaire. The research data were analyzed by multivariate analysis of covariance analysis in SPSS-22.

The findings indicated that schema therapy significantly increased the Temperament and Character dimensions and decrease food craving for the experimental group in the post-test phase (P<0.01).

According to the results of this study, it can be concluded that due to the significant effect of schema therapy on temperament and character dimensions and food cravings in obese women with type 2 diabetes, this treatment can be a good intervention option for the treatment of such individuals.
