Abstract: Considering the needs of athletes to further improve some of the factors of physical preparation that are more applicable in their sports field and also the lack of use of some training methods in special conditions, such as injury and overweight, knowing the effects of different training methods on the factors of physical preparation Effective in the prevention of sports injuries, where balance is at the top, is one of the prerequisites for designing training programs, among which plyometric exercises can be mentioned. The purpose of doing this type of exercise is to increase the physical fitness and performance of the athletes. The general purpose of this study was to investigate the effect of six weeks of specific volleyball training and plyometric exercises on the physical performance of female volleyball players. Therefore, for this purpose, 24 female volleyball players participated in this research as subjects, and after homogenization, they were randomly divided into two experimental and control groups. In the next step, their height and weight were measured and then the records of the specified variables were evaluated through the prescribed tests. Then, the training program in the experimental group for 6 weeks, 3 sessions per week, carried out the selected program of specific volleyball exercises and plyometric exercises, and the control group was not affected by the training interventions and performed their routine volleyball exercises. Data analysis using independent and correlated t-tests showed that 6 weeks of specific volleyball training and plyometric exercises have significant positive effects on research variables, including explosive power, speed, agility and volleyball performance test. The results of this research showed that performing combined volleyball and plyometric exercises has a significant increase in explosive power, agility, speed, balance and coordination (volleyball specific test) and improves the physical performance of volleyball girls.

Abstract: This research explores the factors that influence word-of-mouth among sports consumers, specifically focusing on the mediating role of homophily (interpersonal factors). The current research is a descriptive-correlational study with an applied purpose conducted in the field. The statistical population consisted of all members (both staff and patients) of the Specific Patients and Transplant Sports Federation (IR. SPTF) in Tehran, Iran. A sample of 360 members was selected from the Federation of Special Patients and Organ Transplantation who had watched a documentary film about organ transplantation and special patients on television at least once based on recommendations from others. A targeted sampling method was employed, selecting 360 federation members who completed a word-of-mouth questionnaire. To ensure a test power of 80%, the sample size was determined using SPSS 24 software. Cronbach's alpha test was utilized to assess the internal consistency, resulting in a reliability value of 0.70. Data analysis was conducted using Smart PLS 3 software and the statistical structural equation modeling technique. The findings revealed a significant relationship between word-of-mouth advertising and factors such as experience, expertise, trust, and commitment. Additionally, homophily played a moderating role in this relationship. In conclusion, the characteristics of word-of-mouth advertising and the influence of homophily were found to impact the behavior of sports consumers, motivating them to engage in word-of-mouth promotion.
