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.

Purpose: The aim of this study was to compare the effects of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition male students with overweight. Methods: Forty five overweight male who were resident of Shahed university dormitory were purposefully selected and randomly assigned into following groups: endurance, resistance and concurrent training. Each Group performed their own protocol for 8 weeks, 3 times per week with specified intensity and duration. Before starting the protocol and 24 hours after the last training session, body composition parameters and aerobic fitness were measured at same condition. Data were analyzed using analysis of covariance. Results: The findings showed that three methods of endurance, resistance and concurrent training protocol had a significant effects on aerobic fitness and body composition parameters. In comparing the difference between groups of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition parameters were significantly different and the variables of aerobic fitness and body composition parameters of concurrent training was more effective than two other exercises. Innovation this research is identical the work out of training (time) in the 3 protocol that to compare intergroup among the most effective way to same time identification. Conclusion: It seems that eight weeks of endurance, strength and concurrent exercise training have effects on aerobic fitness and body composition parameters male students with overweight but all three types of exercise separately with diet modification could be improved aerobic fitness and body composition indices.

This paper proposes a categorization of sport that is based on the system of rules that a sport must adhere to. We focus on these systems of rules to examine how a winner is produced in different sports. The rules of a sport dictate the gameplay and the direction it takes. We propose to break down the gameplay into Events. At this junction, we observe two kinds of events – ones that follow sequential logic and ones that do not. Our focus is pertained to sports that comprise sequential events. To examine these events further, to understand how a winner emerges, we take the help of Finite State Automaton from theory of computation (Automata theory). We showcase how sequential sports are eligible to be represented as Finite State Machines. We depict these Finite State Machines as State Diagrams. We examine these State Diagrams to observe how a team/player reaches the final states of the sport, with special focus on one final state – the final state which determines the winner. This exercise has been carried out for the following sports: Hurdles, Track, Shot Put, Long Jump, Bowling, Badminton, Pacman, Weightlifting (Snatch). Based on our observations of how this final State of winning is achieved, we propose a categorization of sports.

A Review of Infertility, Lifestyle, and Physical Activity

Infertility is a health problem that affects about 10-15% of couples worldwide. Infertility is defined as the inability of couples to successfully conceive a child after one year of unprotected sex. The causes of infertility are often not easily identified. However, this disorder appears to be due to genetic or environmental factors, some of which may be modifiable and may be considered as a treatment option. The use of emerging infertility treatment technologies has been somewhat effective. However, these methods are very expensive and, in some cases, their success rate is relatively low. A sedentary lifestyle can lead to several disorders such as cardiovascular diseases, diabetes, cancer and conditions such as obesity. Obesity can have a negative effect on the fertility of couples. Overall, it seems that changing the sedentary lifestyle and increasing physical activity by performing regular exercise training can enhance the chances of fertility. However, it should be noted that strenuous exercise training has a negative effect on fertility.

Purpose: The purpose of this study is to summarize the results of existing studies that addressed the relationship between some effective variables in sporting events (with emphasis on quality component features). Method: The methodological design followed three steps data collection, data coding, and statistical analysis. The study examined two databases (ISI WoS and Scopus) and analyzed 71 relationships. The metafor software from the R package used for analysis. Also, the coefficient of correlation r as a metric to measure the effect size of the studied scope variables. Findings: These findings provide empirical support for several previous studies. In other words, the relatively large effect size on the relationship between each of the variables considered in this study obtained. In such a way that event quality with satisfaction, perceived value with behavioral intention, perceived value with satisfaction, event quality with behavioral intention, satisfaction with loyalty, and finally satisfaction with behavioral intention obtained effect sizes (0.52), (0.56), (0.59), (0.64), (0.61), (0.62), respectively. Conclusion: Considering the meta-analytic approach in this study, it can be noted that managers and officials of sports events in their future decisions can have a more comprehensive and deeper understanding of the relationship between the variables studied in this study; and implement their strategies accordingly.
