Academic interest in athletic performance is ongoing. To examine the correlation between athletic performance and athletes’ personality types, data extraction in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was completed in October 2021, and a meta-analysis was performed using 180 data from 18 selected papers using the “meta” package version 4.8-4 of R Studio 3.3.3. As a result, these selected studies proved to have reliable quality in proceeding with this study via quality assessment. The overall effect of personality on athletic performance (AP) was ESr = 0.124, p < 0.01. Furthermore, only conscientiousness (ESr = 0.178, p < 0.001) and extroversion (ESr = 0.145, p < 0.01), among the five personality types, showed statistically significant results, and these two personality types had a positive correlation with performance. In the publication bias test, this study found that (a) agreeableness had a publication bias; but, with an additional test using trim-and-fill, (b) the effect was not significant enough to be considered. In addition, the analysis of the moderating effects was conducted in four aspects, and all moderating effect analyses showed statistically significant differences between the groups, demonstrating the heterogeneity of this study. Therefore, this study found a significant relationship between personality and athletic performance and showed the importance of conscientiousness and extroversion.

Previous studies have shown that burnout negatively affects athletes’ mental health. To further explore this subject, we conducted a systematic review and meta-analysis by combining data from previous studies. This study followed the PRISMA guidelines for systematic and reliable research and completed data extraction using 10 databases and 8 keywords in December 2021. There were 93 cases of initially extracted data from the selected articles (n = 14) and the meta-analysis was conducted using the “meta” package, version 4.8-4 of R Studio 3.3.3, with data (k = 77) excluding other-oriented perfectionism data (k = 16). The results showed that self-oriented perfectionism had a negative effect on sports devaluation (SD) (ESr = −0.246, p < 0.001), and socially prescribed perfectionism had a positive effect on emotional/physical exhaustion (ESr = 0.150, p < 0.05) and SD (ESr = 0.138, p < 0.05). Furthermore, the test for publication bias showed that no groups had asymmetrical data, and four moderator analyses were conducted to prove the heterogeneity (I²) of the total effect size; however, there was no difference among groups (Q_B), thereby resulting in unexplained variance. Consequently, this study presents variable data that determine the effects of perfectionism and burnout on elite athletes.

This study examined strokes, marital intimacy, marital satisfaction, and divorce intentions among participants who are members of a couple, based on their leisure sports participation. We conducted a questionnaire survey with 321 participants. The validity and reliability were checked, and a multivariate analysis of variance was conducted to test for differences between groups. The results revealed that among couples engaging in the same leisure sports activity, positive stroke was high, and negative and no strokes were low. Couples not engaging in the same activity exhibited a partial positive effect when both or one of the individuals engaged in leisure sports activities. Among couples in which both individuals did not engage in leisure sports activities, negative results were found for all factors. Furthermore, couples engaging in the same activity showed high marital intimacy and satisfaction. Moreover, couples engaging in the same activity showed the lowest intention to divorce, whereas couples who did not engage in leisure sports activities showed the highest intention to divorce. These findings suggest that leisure sports activities positively affect relationships, and this effect increases when couples participate in the same sport. Future research should investigate methods for couples to engage in leisure activities and how they can be activated.

The purpose of this study is to analyze and clarify the relationship between the MZ generation’s participation motivation in screen golf, self-esteem, and psychological happiness. To reach the goals of this study, 300 MZ generation screen golf participants were selected for this study. Accordingly, a questionnaire was distributed and 275 questionnaires were used for this study, excluding the answers that were omitted or unfaithful. SPSS Version 29.0 was used to show the frequency analysis, exploratory factor analysis, correlation analysis, and multiple regression analysis of the research. The results of this study are as follows. First, it was found that the participation motivation of MZ generation screen golf participants had significant effects on positive self-esteem. Second, it was found that the participation motivation of MZ generation screen golf participants had significant effects on negative self-esteem. Third, it was found that the participation motivation of MZ generation screen golf participants had significant effects on psychological happiness. Fourth, it was found that the self-esteem of MZ generation screen golf participants had significant effects on psychological happiness. This study shows how to screen golf as part of a healthy leisure culture for the MZ generation and can enhance its psychological factors.
