Student athletes

Justice as a basic necessity of social life, plays a critical role in administration of sport teams and sport organization. The aim of the present study was to investigate the relationship between Perceived Organizational Justice in Collegiate Sport Teams and Sport Achievement Motivation. In this descriptive –correlative study, 102 student athletes (56 males, 46 females) who were selected as statistical sample from Northern Khorasan and Razavi Khorasan provinces responded to Organizational Justice Questionnaire developed by Niehoff & Moorman (1993) and sport achievement motivation Questionnaire developed by Gill et al. (1983). Conducting correlation coefficient for data analysis revealed that perceived organization justice and its subscales significantly correlated to sport achievement motivation in collegiate sport teams. Moreover, the results of the stepwise regression revealed that, among perceived organization justice subscales, interactional justice was the strongest predictor of sport achievement motivation.

Objective: This study aimed to examine the impact of rumination on both cognitive and sports performance, with sleep quality serving as a mediating factor.Methods: The research was practical in purpose and employed a structural equation correlation design, conducted in a field setting. The statistical population consisted of all student athletes who participated in the table tennis tournaments in Khorasan in 2022, totaling 97 individuals. Sampling was performed using a census method, with 80 participants consenting to engage in the study. Data were collected using the rumination questionnaires developed by Nolen-Hoeksema and Morrow (1991), a sports performance scale by Charbonneau et al. (2001), a cognitive performance assessment by Folstein et al. (1975), and the Pittsburgh Sleep Quality Index (1989). For data analysis, Pearson's correlation coefficient and path analysis modeling were utilized. Results: The findings indicated that rumination has a direct influence on both cognitive and sports performance (P=0.01). Furthermore, rumination significantly affects these performances indirectly through the mediation of sleep quality (P=0.01) among student athletes. Conclusion: Based on the results of this study, rumination is correlated with cognitive and sports performance both directly and indirectly via sleep quality. It is recommended to engage a sports psychologist to conduct educational workshops on rumination management and to monitor and regulate the sleep patterns of student athletes.
