The purpose of this study is to investigate the effect of brand, design and price on the perceived quality and re-intention of consumers to buy sport brand shoes. This is an applied research conducted as a descriptive correlational study in field form. The statistical population of this study included all physical education students across different educational levels in Iran. In this research, 720 questionnaires were collected by random cluster sampling. Structural Equation Modelling (SEM) with PLS software was used to analyse the data of this research. The results of this study show that design with a coefficient of 0.36, price with 0.27, and brand with 0.26 have a significant effect on quality perceived by customers. The results of this research also show that perceived quality with an effect coefficient of 0.49 has a significant effect on customers’ purchase intention. Generally speaking, it can be concluded that the components of design, price, and brand of sport shoes for Iranian physical education students are very important. Famous brands in the world need to pay particular attention to these components to tap into this lucrative market in Iran and increase their re-purchasing intention by influencing consumers’ perceived quality.

Purpose: Creatine is the most important and commonly used supplement in athletes. The purpose of this study was to investigate the simultaneous effect of moderate altitude and short-term Creatine supplementation on musculoskeletal damage indicators in male climbers. Method: 16 male hikers with at least 2 years of hiking experience selected. Subjects (age 30.6±6.3 yrs.), (height 178.3±6/4 cm), (weight 77.6±11.25kg) were randomly divided into experimental (Creatine supplement) and control groups (placebo). The experimental group consumed 20 gr/day of the supplement for 5 days, while the control group received a placebo. The first blood samples were taken before the hiking session at the location of program. Hiking program consisted of ascending to Tochal peak at an altitude of 3961m. The second blood samples were taken after returning from the peak at an altitude of 3750 meters. The results were analyzed by SPSS software using independent t-test and K-S test with a significant coefficient of 0.05. Results: The results showed that there was a significant difference between LDH and AST enzyme levels in post-test compared to pre-test in both AST (P = 0.13) and ALT (P = 0.001) levels Control group. Also, climbing to 4000 m altitude with Creatine supplementation had no significant effect on LDH (P = 0.78) and AST (P = 0.86) levels between groups. Conclusions: The results showed that changes in muscle damage enzymes are independent of Creatine supplementation.

The purpose of the present study was to investigate the relationship between environmental knowledge and sport event organizers' support for sustainable management in sport. The present study is a descriptive-survey and field study. In order to collect data, a researcher-made questionnaire with 40 questions was used. The face and content validity of the questionnaire was confirmed by a survey of professors related to the research topic. The construct validity was confirmed by confirmatory factor analysis of more than 0.3 and its reliability was confirmed byCronbach's alpha of 0.83. The statistical population of the study consisted of managers and organizers of sport events in ten provinces of the country with approximately 1000 peope. The sample size was 278 according to Morgan table, Due to the size, number and difficulty of access, the available sampling method was used to collect the samples and finally 254 questionnaires were returned. Data analysis was performed using SPSS-19 software. The results showed that the level of environmental awareness in the sample was in the range of 0 to 8 and the mean of the total sample was 3.55 with a standard deviation of 1.61. These results indicate a low level of awareness of environmental issues in the sample under study. In the present study, it seems that there is little awareness of environmental issues that may be effective in shaping people's attitudes toward the intention to support environmental issues in sporting events. Since human attitudes are driven by consciousness, it is therefore necessary to change attitudes by providing a context for raising awareness and enabling appropriate behavior. Therefore, determining the level of knowledge and attitude of individuals is the first step in determining and delivering educational programs.
