Introduction: Energy Consumption (EC) and Body Mass Index (BMI) are the major complications associated with Spinal Cord Injury (SCI), which can be improved by exercise rehabilitation. Thus, the present study aimed to evaluate the efficiency of using rebound therapy (exercise on a trampoline) on EC and BMI in individuals with SCI. Materials and Methods: Sixteen individuals with SCI (ASIA classification: A=6, B=6, C=2, D=2) were selected and randomly divided into two groups of experimental (rebound exercise) and control. The experimental group performed the exercise program by a modified trampoline for 12 weeks (10-30 minutes; 3 sessions a week). EC was measured by the Physiological Cost Index (PCI) and BMI was calculated by standard formula before and after the exercise intervention. Finally, the obtained data were analyzed by Repeated-Measures Analysis of Variance (RM-ANOVA) in SPSS. Results: The results of RM-ANOVA revealed significant interaction in both criteria (P<0.01). In other words, the experimental group changes were substantial, compared to that of the control group. Conclusion: The collected results indicated that rebound therapy could, in effect, improve the SCI individuals’ EC and BMI. Furthermore, it was suggested that rebound exercise can be a useful sports rehabilitation method for patients with SCI.

Sport, and especially public sports, is very important because it increases life expectancy by promoting community health. The purpose of this study was to investigate the role of privatization in the development of participation in public sports in Alborz, Iran. This study was a mixed research (qualitative and quantitative). In the qualitative phase, the participants included 12 university faculty members and public sports administrators. In the quantitative section, 384 people were selected as a statistical sample based on Morgan table. Amiri et al.'s Privatization Questionnaire (2013) and a researcher-developed questionnaire were used to measure the research variables. Confirmatory factor analysis and structural equation modeling were used to test the research hypotheses. The results showed that privatization has a critical role in the development of participation in public sports in Alborz province. Therefore, expansion of the role and position of the private sector is one of the actions that can be taken in this field. It is suggested that sports, health and well-being officials seriously consider privatization in order to facilitate and increase the participation in public sports. 

Purpose: This research aims to investigate the quadruplet role of modern media (education, informing, making social participation, and culturing) on the development of Zurkhaneh sport. Method: This research is applicable in terms of objectives and is descriptive research in terms of data gathering methods. The statistical society of this research includes the athletes, experts, and activists of sports media in the context of the Zurkhaneh sport. Because the exact number of this society was not clear, the number of 384 persons were selected by random sampling. Its measuring tool was the researcher-made questionnaire that 12 professors and experts approved its content validity and its reliability was calculated using the compound reliability (Dillon – Goldstein) and was about 0.82. In addition, the SPSS software was used to analyze the data and PLS software was used to preset the model. Results: The results show that the “informing” factor had the maximum role in developing the Zurkhaneh sport with the factor loading of about 0.93. The other factor that had many roles in developing the Zurkhaneh sport was the “social participation” with the factor loading of about 0.91. The “education” factor with the factor loading of about 0.90 was in third place and the last factor was the “culturing” with the factor loading of about 0.90. Conclusions: According to the results of this research, it could be stated that modern media have obtained such power in the communication era that could affect public opinion. Therefore, the potentials of the modern media and their infinite capacity can be used by proper and correct operational planning to make great movements in developing various aspects of Zurkhaneh sport inside and outside of the country.
