Abstract
Background: It has been shown that C1q TNF-related protein 5 (CTRP5) is a novel adipokine and important molecule related to metabolism regulation. This study aims to assess the effectiveness of different training protocols on improving serum levels of CTRP5, fasting blood glucose, insulin, Insulin resistance in patients with T2DM.
Methods: Sixty men with T2DM (mean age [X̅±SD]=51.45±4.26 years) were randomly assigned to combined exercise group (CEx: n = 15), aerobic exercise group (AEx: n = 15), resistance exercise group (REx: n = 15), or the control group (CON: n= 15). Exercise programs consisted of aerobic exercises at either AEx (50% - 75% of HRR) or REx (70% - 85% of 1-RM), of equal volume, 3 times per week, 45 to 60 minutes per session for 12 weeks. Serum levels of CTRP5, fasting blood glucose (FBG), insulin, Insulin resistance (IR) and body mass index (BMI) were measured at baseline and at the end of the study. The data were analyzed using repeated-measures analysis of variance.
Results: After 12 weeks intervention, FBG, insulin, HOMA-IR and BMI levels decreased significantly, whereas the serum CTRP5 levels increased in the CEx, AEx and Rex groups compared to control (P < .05).
Conclusion: It appears that the increased levels of CTRP5 following exercise interventions contribute to the decreased risk of T2DM.

Abstract
Background: Diabetes is the most common glandular disease in the world. The aim of this study was to compare the effect of three types of endurance, resistance and combination training on inflammation and insulin resistance in visceral adipose tissue of type 2 diabetic rats.
Methods: For this purpose, among eight-week-old male Wistar rats, 48 rats were selected and randomly divided into 6 groups (diabetic endurance training, diabetic resistance training, diabetic combination training, healthy combined training, healthy control and diabetic control). The rats became diabetic by injecting 95 mg of nicotinamide and after 15 minutes of STZ injection at the rate of 55 mg/kg body weight. 4 days after injection, rats with serum glucose above 300 mg/dL were considered diabetic. Then, the endurance training group trained for 6 weeks, 3 sessions per week with moderate intensity (50-60% of maximum oxygen consumption). The initial load to start resistance training was 50% of the rat's body weight. Each session added 15% of body weight to the weights. The combined exercise group also performed resistance and endurance exercises in a row. 48 hours after the last session, the rats were anesthetized and visceral adipose tissue was removed to examine the variables.
Results: The results showed that there was a significant difference between the effect of six weeks of endurance, resistance and combined exercise on inflammation and insulin resistance in the visceral adipose tissue of male diabetic mice.
Conclusion: The results confirm the effect of three training methods on the mechanisms involved in diabetes.

Abstract
Background: Obesity has been recognized as one of the top 10 health problems by the World Health Organization. The purpose of the present study was to the effect of aerobic training on atrogin, eotaxin and IL-10 indices in obese women.
Method: The present applied research was a quasi-experimental study in which 30 obese women aged 30-45 years were selected by available method from South Tehran Azad University (2016-2017) and randomly divided into two groups of aerobic exercise and control. 24 hours before the start of training, the individual characteristics of the subjects and the research variables (atrogen, eutoxin and IL-10) were measured in blood tissue, then the subjects of the experimental group had their training program for 8 weeks, 3 They performed one session per week and each session lasted 45-60 minutes under the supervision of a researcher. Dependent and independent t-test was used to analyze the data.
Results: Due to the lack of differences in pre-test scores, it was found that the groups were identical. It was also found that 8 weeks of aerobic exercise had a significant effect on the levels of eutoxin, atrogen and interleukin-10 in obese women (p = 0.001)
Conclusion: According to the research results, it is recommended that obese women exercise aerobically. Use to reduce the negative effects of obesity.

Abstract
Background: Diabetic myopathy is one of the major problems in people with type2 diabetes that knowing its mechanisms can be helpful in controlling and preventing this disease. PAX7 and PGC-1α are two proteins involved in the renewal and metabolism of carbohydrates in skeletal muscle. The aim of this study was to evaluate the effect of 8weeks of resistance training under hypoxia on the content of PAX7 and PGC-1α proteins in the horseshoe muscle of type 2 diabetic rats.
Methods: In this study, 40 male Wistar rats, 10weeks after induction of type2 diabetes, were divided into five groups: healthy control (HC), diabetic control (DC), resistance training (RT), and resistance training in hypoxia (RT-HPX) and hypoxia group (HPX) were divided. Resistance exercises were performed for 8 weeks, 5 sessions per week, in the groups of resistance training and resistance training in hypoxia. The intensity of the exercises started from 30% of the weight of the rats initial and reached 100% of their weight until the end of the training. Resistance training in hypoxia. Hypoxia tent with14.4%oxygen was used to create hypoxia. 48hours after training, tissue samples were taken from horseshoe muscle and evaluated to measure the concentration of PAX7 and PGC-1α proteins.
Results: The results showed that there is a significant difference (P=0.0001) between the research groups in both PAX7 and PGC-1α proteins. Induction of diabetes led to a significant decrease in PAX7, but the hypoxia resistance training group was not significantly different from the healthy control group (P=0.451). PGC1-α protein levels were also significantly decreased in the diabetes induction group compared to the control group (P=0.01), but training in hypoxia increased its levels to more than the healthy control group (P=0.0001).
Conclusion: Hypoxia, resistance training and combination of resistance training in hypoxia increased the amounts of PAX7 and PGC-1α proteins. Therefore, resistance training and temporary and inactive hypoxia exposure can be considered as a suggested solution to improve the indicators related to type2 diabetes in humans.
