The present research aims to investigate the effect of massage on fatigue and mood in female rowers. Pre-test and post-test of quasi-experimental design with a control group was used for the experiment. Participants in the study were 30 female rowers from Tehran province who participated voluntarily. The volunteer sample was randomly assigned into two experimental and control groups (15 people in each group). Pre-test was carried out for both groups. The subjects in the experimental group then participated in 12 massage sessions under the supervision of a massage expert. Meanwhile, both groups also continued their normal rowing exercises. At the end of the intervention, post-test was carried out for both groups. Rating of perceived exertion and fatigue scale (Borg, 1982), mood questionnaire (Vaez Mousavi, 2007), and a researcher-made questionnaire were used to measure variables. Statistical analysis of variance with repeated measurements was used to test the hypotheses. The results suggested that perceived intensity and fatigue were significantly reduced in the massage group compared to the control group (P <0.05). Also, anger (P=0.002), confusion (P=0.02), depression (P=0.028), mood fatigue (P=0.015), and stress (P=0.039) significantly decreased in the massage group compared to the control group. Force increased significantly in the massage group compared to the control group (P=0.008). In general, the results showed that 12 massage sessions could be used to decrease fatigue and improve mood in female rowers.

The purpose of this study was to investigate the factors affecting the sudden buying of sportswear in sports stores in Mazandaran, Iran. This applied research has been done by descriptive-survey method. The statistical population of the study was the customers of a reputable sports store in Mazandaran province. 385 customers were selected through  available sampling method. A valid and reliable researcher-developed questionnaire was used for data collection, and structural equation modeling (SEM) was conducted for data analysis and hypotheses test. The results showed that the store environment (light, color, music, fragrance) has a positive effect on the sudden buying behavior of store customers. Moreover, the findings demonstrated that layout and physical appearance (Product availability, booth guide, product layout, building appearance, and staff coverage), as well as facilities available in the store and ancillary services (cafes and restaurants, amusement parks, child care centers), affect the psychological characteristics of customers' sudden buying behavior. By focusing on the research findings, the managers of sports stores can have a positive impact on customers’ sudden buying and improving the selling approaches.

Given the critical role of sport managers’ behaviors in developing efficient processes in sport settings, the aim of the current study was to provide a model of sports managers’ strategic behavior. The research participants were selected theoretically through a snowball sampling approach. Semi-structured interviews were conducted with professional sport managers to collect the research data. Grounded Theory (GT) with a Systematic Approach was applied for data analysis. The results of qualitative data analysis from the interview were presented as a paradigm model of strategic behavior of sports managers in the form of six dimensions of the paradigm model, including causal condition, the main phenomenon (strategic behavior of managers), contextual condition, intervening condition, action /interaction strategy, consequences. The categorization based on the relationships between the concepts around the behavior of managers presents the paradigm model of the strategic behavior of sports managers. According to the findings, managers can eliminate many of the strategic barriers in sports organizations by institutionalizing strategic thinking and making decisions based on strategic behavior. 

The purpose of this study was to investigate the relationship between coaches’ leadership styles and sport emotions of athletes participating in the Bahrain 2021 Para-Asian Youth Championships. The statistical population of the study consisted of all athletes participating in the Bahrain 2021 Para-Asian Youth Championships including 750 athletes from 30 Asian countries. Using Morgan table, the sample size was determined to be 256 athletes. The research instruments included the Modified Sport Emotion Questionnaire (SEQ) and the Sport Leadership Scale (LLS). Kolmogorov-Smirnov test, Pearson correlation coefficient, independent t-test and Friedman test in SPSS 23 software were used to analyze the data. The results showed that the leadership style of social support of sport coaches had a negative and significant relationship with the components of anxiety, dejection, excitement and anger of athletes’ sport emotions as well as a positive and significant relationship with the component of happiness. The authoritarian style of sport coaches had a positive and significant relationship with the components of anxiety, dejection and anger of athletes as well as a negative and significant relationship with the components of excitement and happiness (p≤0.01). Generally, by recognizing the psychological consequences associated with coaches’ leadership style, it is possible to help improve positive emotional states and control negative emotional states in athletes.
