رابطه اوقات‌فراغت جدی و رضایت از فراغت با میانجی‌گری مشارکت تفریحی در ورزشکاران آماتور والیبال

Leisure under the effect of socio-economic developments and global values is one of the concerns of individuals. Leisure activities can affect people's physical health and lead to a better life and successful aging in adults. On the other hand, the growth and development of machine life, reduction of working hours and activities, most importantly cultural changes, have made it impossible to ignore your leisure time. The statistics obtained in this field showed that the average lisure time in Iran is 90 days and in the world 80 days per year. The average amount of leisure time in Iran is 3 hours and 29 minutes per day, while the world average is 5 hours. This means that despite the fact that Iranians have more leisure time than the world per capita, the amount of time allocated to it is less and Iranians prefer to spend their budget on other things. Therefore, the vacuum created in this field is questionable as to what factors prevent people from doing leisure activities in their free time, and also the factors that increase leisure activities, to what extent can be increased and strengthened. Due to the tendency of sports and physical education managers and sports media towards championship sports, so far less attention has been paid to leisure sports activities. The subject to be investigated in this context is how much leisure time can affect the satisfaction of the activity and whether the factors affecting the increase of leisure time also increase the satisfaction or not. The purpose of the present study was to investigate the effect of serious leisure on satisfaction from lelisure activities with the mediation of recreational involvement in amateur volleyball athletes. The research method was applied in terms of purpose and correlation interms of data collection, which was done in the field. Data collection tools were questionnaires of Gould et al (2008), Kyle et al (2005) and Ramkisson et al (2012). The target population of the study was non-professional athletes of Tehran Volleyball House who had at least 6 months of membership in this collection. PASS Software was used to determine the sample size and the sampling method was available. Finally, 274 questionnaires were used for statistical analysis. The face and content validity of the data collection tool was reviewed by 9 experts in this field. Cronbach's alpha was 0.95. In order to analyze the data, descriptive and inferential statistical methods were used using SPSS software version 26 and PLS version 3. The Findings showed that if a participant has serious leisure traits, more likely than others to understand the importance of the activity and enjoy its appeal. On the other hand, people should have characteristics such as individual efforts, perseverance and commitment in the activity to pursue recreational activities. one of the most important factors to increase people's satisfaction with leisure activities is recreational participation (Path coefficient 0.519). Among the dimensions of recreational participation, attraction has the greatest impact (Path coefficient = 0.449 and AVE = 0.747), so it can be said that the more irritable people are to an activity, the greater their satisfaction. Entertainment participation predicts 49% and serious leisure 42% of changes in leisure satisfaction, and 66% recreational involvement of changes depend on the serious leisure of volleyball players. taking into account the mediating role of recreational participation in the relationship between serious leisure and leisure satisfaction, the results showed that despite dimensions such as attraction, self-expression, centrality of lifestyle, the relationship between the two variables of serious leisure and leisure satisfaction becomes stronger. Recreational participation with its mediating role can create a positive experience in people and their satisfaction with recreational activities. According to the output of the software used in this research, 51% of the changes in satisfaction with leisure activities are related to recreational participation and serious leisure of non-professional volleyball players of Tehran Volleyball House. Therefore, considering a factor such as recreational involvement can be a great help to the officials in the field of leisure to attract and satisfy more customers of Tehran Volleyball House. In the present study, the relationship between perseverance and customs on leisure satisfaction was not significant. This issue can be interpreted as that the researches were conducted on old people and adults, but according to the descriptive findings of the research, 45.6% of the statistical sample of the current research were under 20 years of age, so they endure problems and hardships and barriers to leisure. Seriously, it's probably difficult for them, and they don't have a proper understanding of customs and subcultures. But the identity of volleyball players is very important in their leisure time. People who follow volleyball as a serious leisure identify themselves with volleyball, and their family and friends also know how important it is for a volleyball player to do volleyball activities. With the improvement of athletes' performance in this area and their efforts, their satisfaction with volleyball will also increase. Educators should know that by knowing the goals of their students, they can help them achieve their goals. The design of exercises that are accompanied by pleasure and happiness by volleyball coaches can attract athletes more to this discipline, so that they prefer volleyball to other sports. The participants in the volleyball field who are satisfied with their leisure activity in the volleyball house know that their life is connected to volleyball, so they plan in life in such a way that the position of volleyball is always reserved. The managers of the complexes can increase the attractiveness for the volleyball players or create suitable conditions for the participants who can show a good image of themselves to others, causing them to be satisfied with the activities they do, which ultimately leads to the loyalty of the volleyball players. For example, having up to date sports equipment, designing exercises with joy and pleasure, and giving athletes the opportunity to discuss volleyball can be very important in the field of loyalty of volleyball players. The participants in the volleyball field who are satisfied with their leisure activity in the volleyball house know that their life is connected to volleyball, so they plan in life in such a way that the position of volleyball is always reserved.
