The purpose of this study was to develop a framework for presenting a model for the development of doping-free sports in Iran with a combined design approach. The research method was a two-stage exploratory combination of instrument making. Qualitative research method, qualitative case study and potential participants included 17 faculty members. The research tool was a semi-structured interview. In the quantitative part, the research method was descriptive survey. The statistical population of this study included the president, vice president and secretary of sports federations, whose number was 153 according to the 51 active federations in the country. According to Morgan's table, 113 people were identified as the research sample based on the available sampling method. Ten faculty members of sports management were used to evaluate the face validity and the carcass model was used for the content validity of the questionnaire questions and the content validity was confirmed. Convergent validity, hybrid reliability and Cronbach's alpha were also confirmed. Descriptive statistics and structural equation modeling were used to analyze the data to evaluate the fit of the research model. The results showed that the amount of t in each factor has a significant effect and the whole framework of the doping-free sport development model in Iran was approved. Also, the results of the present study showed that the presentation of a model for the development of doping-free sports in Iran includes causal conditions, contextual conditions, intervention conditions, consequences, and strategies. Also, the results of the present study showed that the research model has a good fit.

The purpose of this study was to identify and model the most important factor of pure sport development model in Iran with interpretive structural modeling approach.

The purpose of this study was applied and in terms of data collection, it was a field research. With regard to the main purpose, the research method was qualitative (foundation data theory). The statistical population in this study includes experts in the field of sport management. Using purposive sampling and theoretical saturation technique, key informants (including 17 experts in the field of sport management with focus groups (to It was done and the components and factors of pure sport development model were identified in Iran and then interpretive structural modeling was used as one of the consensus methods.

The results showed that the factors of cultural factors, skills and motivation with power High influence, individual and organizational factors, moral consequence, and societal consequences with subordinate power The above and the managerial and structural factors have high influence and dependency, so the framework of Clean Sport Development Model in Iran provides a deeper understanding and broader perspective to the researchers and extends the scope of Clean Sport Development Model in Iran to a specialized field.

The present study suggests that the framework presented is based on a global philosophy and values, and it seems that the use of pure sport development in sport seems to give rise to some ethical principles and values during implementation. Emphasize and implement sports activities

Consumption of non-enzymatic antioxidants in the form of dietary supplements can have a positive effect on reducing oxidative stress by hunting free radicals. The aim of this study was to explain the effect of 6 weeks of increasing and complementary L-carnitine aerobic exercise on the apline of the cardiac tissue and the blood glucose levels of diabetic mice.

In this experimental study, 40 males of Wistar male rats were randomly divided into five groups: healthy control, diabetic control, diabetes-L-carnitine, diabetes + aerobic exercise and diabetes + exercise + L-carnitine. After diabetic rats, they were given 100 mg of L-carnitine orally daily. The aerobic exercise program started 5 days a week, for six weeks, with a slope of zero degrees, a speed of 10 meters and a time of 10 minutes in the first week, and in the last week the slope reached 5 degrees, a speed of 20 meters and a time of 40 minutes.

The results showed a significant increase in apline in diabetes groups + aerobic exercise and diabetes group + aerobic exercise + L-carnitine compared to the control group and placebo (p = 0.001). There was no significant difference between the two active research groups (p = 0.274). The results of the follow-up test showed a significant decrease in glucose in the active groups compared to the control and placebo groups (p = 0.001).

Aerobic exercise and L-carnitine consumption can increase the apline receptor of cardiac tissue and reduce glucose.

Adipokine apelin plays an important role in regulating energy homeostasis and improving insulin resistance. The purpose of this study was to investigate the interactive effect of aerobic exercise and L-carnitine supplementation on serum levels of cardiac tissue apelin and insulin resistance in diabetic rats.

In this experimental study, 40 male rats were randomly divided into five groups of healthy control, diabetic control (placebo), diabetes + L-carnitine, diabetes + aerobic exercise, and diabetes + L-carnitine + exercise. After induction of diabetes in rats, aerobic exercise and L-carnitine supplementation were performed for six weeks and five sessions per week. Aerobic training in the active groups consisted of 10 minutes of treadmill exercise with 60% of maximal oxygen uptake, which increased by 20 minutes from the third week, with no control group training.

There was a significant increase in apelin in the diabetes + aerobic training group and the diabetes + aerobic training + L-carnitine group compared to the control and placebo groups (P = 0.001). There was no significant difference between the two active groups (P = 0.227). There was a significant decrease in insulin and glucose levels in the active groups compared to the control and placebo groups, too (P = 0.001).

Aerobic training and consumption of L-carnitine can increase cardiac tissue apelin and decrease insulin resistance.
