Background: Sport heritage is increasingly being recognized as a potent instigator of tourism. The convergence of heritage, sport and tourism involves many different and diverse fields, including sport tourism, heritage tourism, sport management. Aim: The purpose of this study was to identify the effective factors on the development of heritage sports tourism with an interpretive structural modeling approach (ISM). Materials and Methods: The present research is applied, qualitative and analytical in terms of nature and purpose, data retrieval, and data analysis method, respectively based on interpretive structural modeling. Data collection tools in this study were library studies, interview and questionnaire based on interpretive structural modeling. In order to identify the factors affecting the development of heritage sports tourism, with the collective agreement of experts and reviewing the research literature, 16 factors affecting the development of heritage sports tourism were identified. Results: According to the third step of the ISM method, the effective factors on the development of heritage sports tourism were classified into 7 levels and the political and governmental dimensions along with the rule of law were at the lowest level of the model (seventh level); these are prioritized in terms of implementation over other dimensions. As a result, officials and managers in the field of tourism and sports tourism should pay special attention to these dimensions in order to provide the ground for the emergence and realization of other dimensions at higher levels of the model. Finally, based on the analysis matrix of influence and dependence, it was determined that the political and governmental dimensions, rule of law, management and supportive factors are among the influence factors; economic dimensions, socio-cultural factors, infrastructure and welfare services, education and research, specialized human resources, technology, heritage sports tourism attractions, heritage, marketing and information and international relations are among the linking factors; and the dimensions of safety and security, complementary attractions and sporting events are among the dependent factors in this research. Conclusion: According to the results of the model, for the development of heritage sports tourism, there must be a serious determination. In this regard, the policies of a nation must be progressive, and in the first step, government with a decisive role must provide the infrastructure.

Background: Vaspin is an adipokine secreted from fatty tissues that has serious effects on adipose tissues, muscles, liver, and inflammation. Purpose: The study aimed at determining the effects of 8 weeks of combined training (resistance and endurance) on the serum vaspin level in obese girls. Method: The examinees consisted of 25 obese female students (BMI> 30) from Sistan-Baluchestan University in 2016-17 academic years who voluntarily participated in the research. Samples were divided randomly into two groups: Training (n = 13) and Control (n = 12). Combined training group had both resistance training (5 stations of foot press, Lat pulldown, biceps curl, knee flexion and knee extension for 75-70 minutes) and; endurance was running on the treadmill; in the 2 first weeks, with 60% HR<sub>max for 25 minutes, in the 3-6 th weeks with 75-65% HR<sub>max for 35 minutes, and in the 6-8 th weeks with 75 -85% HR<sub>max for 40 minutes, continuously, for 3sessions each week. Also 10 minutes at the beginning and at the end of the training were warm up and cool down for athletes. It should be noted that during this period the control group did not participate in any kind of sports activities. After receiving the consent forms, the examinees were given enough information regarding the research procedure and their blood samples were obtained in a standard position, collected in pipes containing EDTA, and centrifuged 24 and 48 hours before and after the first and last training sessions, respectively. The obtained plasmas were kept at -80 ° C and their serum vaspin concentrations were measured by ELISA method using the special Human Vaspin kit. To analyze the data, the paired and independent t-test and SPSS-21 Software were performed; the meaningfulness level p was considered to be less than 0.05 (p < 0.05). Results: Results showed that after 8 weeks of combined training, the vaspin levels, weight, BMI, WHR, and %BF decreased meaningfully in the training Group compared to the control Group (P <0.05). Conclusions: considering the meaningful vaspin reduction in this study, it seems that combined training (resistance and endurance) is beneficial to obese and overweighed people.
