The current study aimed to investigate the relationships between leader-member exchange (LMX) quality, empowerment, and job performance of fitness center instructors. Data were mainly analyzed using a structural equation modeling technique with the AMOS program. The results, based on a paper-and-pencil survey with 263 respondents from 15 fitness centers, reported that LMX quality positively influences the level of empowerment perceived by subordinates while employee empowerment has a positive effect on job performance. However, LMX quality does not statistically influence self-rated job performance. Employee empowerment mediates the relationship between LMX quality and job performance.
The purpose of this study was to investigate the research trends on school sports clubs using the Content Analysis and Network Text Analysis. Data included 137 journal articles published from 2007 to 2016 and were analysed using SPSS 20.0, KrKwic software and the NetDraw of UCINET 6 program.The results were as follows. First, the number of research articles on school sports clubs were increased since 2012. Second, research studies using mixed subjects were most popular in comparison to more narrow target population. Third, the mixed methods approach was less utilised in comparison to quantitative and qualitative research methods. Fourth, correlational studies were more frequently used while multivariate analyses were less common in terms of statistical methods. Fifth, satisfaction, policy, and leader were the most frequently used keywords among the keywords provided by journal articles. Lastly, the results of Network Text Analysis indicated that school sports clubs and user satisfaction showed the highest degree centrality, closeness centrality, and betweenness centrality.
