Elite youth athletes' mental health and its relationship with the talent development environment: A variable- and person-centred approach.

The present research sought to examine the prevalence of elite youth athletes' mental health and its relationship with talent development environments (TDEs). A sample of 248 Chinese elite youth athletes completed a self-report survey measuring demographic variables, TDE factors, and mental health outcomes including generalised anxiety disorder (GAD), depression, and athlete burnout. The results revealed moderate levels of burnout, with 19% of the participants meeting the diagnostic cut-off of GAD, and similar numbers for depression. The multiple regression analysis revealed alignment of expectations was the only TDE factor to significantly predict GAD and depression. Holistic quality preparation was the only significant TDE predictor of burnout. The results of cluster analysis suggested a three-cluster solution: cluster 1-"slightly below average TDE", cluster 2-"high TDE", and cluster 3-"very low TDE". Among the three clusters, cluster 2 had the lowest levels of GAD, depression, and burnout. Cluster 3 reported a higher burnout level than cluster 1, and the two clusters showed no differences in other two mental health outcomes. These findings suggest a need to manage mental health symptoms of elite youth athletes, and the roles of TDE could be considered in the management of mental health.

Compulsory volunteers' nostalgia and its relationships with positive memories, age, past experiences, and volunteer intention.

While nostalgia has been explored in various contexts, no research has so far investigated how individuals' nostalgia can be generated by volunteer experiences in compulsory settings and how nostalgic feelings extend their future behavior. To fill this research gap, this study explored how nostalgia regarding compulsory volunteering is related to positive memories, age, and past experiences and how such nostalgia translates to volunteer intention. A total of 605 responses were collected from university students who had completed compulsory volunteering at sporting events and analyzed using structural equation modeling. Results showed that positive memories contributed to all five factors of volunteer nostalgia, while past experiences only predicted volunteer environment, volunteer socialization, and volunteer personal identity. Age was not a significant antecedent to any of the volunteer nostalgia factors. Nostalgia regarding volunteer experience and volunteer personal identity mediated the relationship between positive memories and volunteer intention. This study confirmed previous claims concerning the relationships among nostalgia, positive memories, age, and past experiences in the context of compulsory volunteering. Specifically, individuals can develop nostalgia for coerced experiences if they have fond memories of them. Also, past experiences are more essential to nostalgia than age but not as much as positive memories, and nostalgia can turn compulsory volunteers into continued volunteers.

Cancer family caregivers' quality of life and the meaning of leisure.

In this study, the authors examined cancer family caregivers' life experience and the meaning of leisure, focusing on their difficulties and the role of leisure. We found four main themes related to cancer family caregivers' life and leisure experiences: stressors, adapting, the need of leisure, and leisure experiences. Our results showed that the caregivers experienced high levels of psychological and physical stress and conflicts while caring for cancer patients, resulting in a poor quality of life. They believed that leisure activity is necessary and can improve their quality of life; however, they felt a sense of guilt while engaging in personal activities.

How Do Two Types of Exercise Habits Predict Physical Activity with Intention?

This manuscript investigates how conscious intention and unconscious exercise habits influence physical activity behavior. While prior research has predominantly focused on conscious decision-making, this study applied a dual-process model to explore the impact of intention and habit on physical activity engagement. Out of the 300 questionnaires distributed to students from one university, 282 questionnaires were utilized for data analysis after excluding insincere responses. Intention was measured using a 7-point scale, while exercise habits were assessed using the Self-Report Behavioral Automaticity Index. In addition, physical activity was measured using the Weekly Leisure-Time Exercise Questionnaire. The validity and reliability of measurement tools were confirmed. Data were analyzed using SPSS and AMOS, including correlation analysis, multiple regression, and moderation analysis. Intention, exercise preparation habit, and exercise performance habit were all found to influence physical activity levels significantly. Intention demonstrated the strongest impact, followed by exercise preparation habit and exercise performance habit. This suggests that the research efforts regarding intention conducted before the emergence of the dual process model, which proposes the importance of unconscious thinking patterns, were not in vain. The analysis revealed a statistically significant moderating effect of exercise preparation habit, but not exercise performance habit, in the relationship between intention and physical activity. Exercise preparation habit was identified as a significant moderator, enhancing the relationship between intention and physical activity. This study underscores the importance of considering both conscious intention and unconscious exercise habits in promoting physical activity. The findings challenge the prevailing emphasis on conscious decision-making and highlight the need for a more comprehensive understanding of unconscious behavior in health behavior interventions. This study is expected to arouse academic interest in the often-neglected area of unconscious behavior.

Volunteers' growth mindset and continuance intention: what are the roles of nostalgia and positive emotions?

This study examined the cognitive and affective aspects of volunteering experiences by focusing on the relationships between volunteers' growth mindset, nostalgia, positive emotions, and their intention to continue volunteering. A total of 364 responses were collected from volunteers who had volunteered within the past 5 years. Results showed that the growth mindset had a positive effect on nostalgia, which in turn positively affected valenced emotions toward volunteering. Nostalgia and volunteers' positive emotions positively influenced their intention to continue volunteering. All indirect effects via nostalgia were significant. This study lays the groundwork to identify the role of nostalgia in volunteerism and contributes to extending the literature on growth mindset and mindset theory.

New Times, New Ways: Exploring the Self-Regulation of Sport during the COVID-19 Pandemic and Its Relationship with Nostalgia and Well-Being.

Coronavirus disease (COVID-19) has negatively affected individuals' participation in sport activities, while sport participation is an important regulator of well-being. The current study investigated the effects of the nostalgia for sport activities and self-regulation of sport activities on subjective well-being. A total of 302 responses were collected from participants who had engaged in sport activities before the lockdown period. The data were analyzed using partial least squares structural equation modeling (PLS-SEM). The findings showed that nostalgia positively affected the self-regulation of sport and subjective well-being. In addition, self-regulation of sport was positively associated with subjective well-being. Based on the findings of this study, policymakers can implement interventions that promote an individual's feelings of nostalgia, as it might lead them to engage in sport or promote self-regulation.

Increasing exercise participation during the COVID-19 pandemic: the buffering role of nostalgia.

Introduction: Due to the coronavirus disease 2019 (COVID-19) pandemic, people faced difficulties engaging in exercise activities as usual. As a result, there has been an increase in the demand for home exercises and online sales. However, there is little research on individuals' buying and exercise behaviors during the pandemic. Thus, this study investigated how the perceived threat of COVID-19 influences exercise participants' compensatory consumption and exercise intention through emotional responses, such as feelings of solastalgia and nostalgia. Methods: A total of 488 responses were collected from Generation Y, as individuals belonging to Generation Y are more prone to impulsive buying compared to other generations and, importantly, consider exercise a crucial component of their general well-being. Data were examined using a three-step method that involved the use of SPSS 26.0 and EQS 6.4 software. Results: Results showed that perception of COVID-19 positively influenced solastalgia and negatively affected nostalgia. Also, solastalgia had positive effects on nostalgia and online browsing, and nostalgia positively affected online browsing. Finally, this study found that online browsing positively influenced impulse buying and exercise intention, while impulse buying did not significantly affect exercise intention. Conclusion: This study contributes to identifying the crucial influence of emotions in decision-making and increasing the understanding of the connection between nostalgia and cognitive and emotional responses amid the COVID-19 pandemic.

Understanding sport coaches' turnover intention and well-being: an environmental psychology approach.

OBJECTIVE: The purpose of this study was to examine the role of environmental and personal factors in sport coaches' well-being and behavioral intention. To be precise, this study measured how workplace social support, work involvement, and work satisfaction are associated with sport coaches' well-being and turnover intention, adopting the framework of the environmental psychological model. DESIGN: A total of 519 responses were collected from sport coaches in Singapore. In this study, confirmatory factor analysis and structural equation modeling analysis were conducted using EQS 6.3 software. RESULTS: Results of structural equation modeling supported all hypothesized relationships, except the paths from work involvement to turnover intention and well-being. Additionally, this study found the indirect effects of workplace social support and work involvement on turnover intention and well-being. CONCLUSION: This study provided an understanding of external and internal antecedents of sport coaches' future behavior and well-being, ultimately benefiting sport organizations.

Exercise Participation during the COVID-19 Pandemic: Anxiety, Stress, and Precautionary Behavior.

Understanding emotion is critical, as it influences behavioral responses. In particular, anxiety is one of the most significant factors affecting individuals' behavior during a pandemic situation. However, the effect of coronavirus anxiety on exercise behaviors has not been extensively explored in the extant literature. Therefore, this study examined the relationships among coronavirus anxiety, stress, precautionary behavior, and exercise participation. A total of 307 responses were collected from individuals who experienced the full length of the circuit breaker in Singapore. Data were analyzed using partial least squares structural equation modeling (PLS-SEM). Results showed that coronavirus anxiety had positive effects on stress and precautionary behavior. In addition, precautionary behavior played a mediating role in the relationships among coronavirus anxiety, stress, and exercise participation. The findings of this study identify how COVID-19 affected exercise participation during that period and suggest strategies to promote exercise participation, which would benefit individuals and governments.

The Effectiveness of Physical Activity Interventions on Depression in Korea: A Systematic Review and Meta-Analysis.

Since the onset of the COVID-19 pandemic, Korea has ranked first in the OECD, with a prevalence of 36.8% of depression. Thus, this study aimed to estimate the effect size of physical activity as an alternative tool for depression symptoms using meta-analysis. A meta-analysis on depressive symptoms was performed on 18 studies published in Korean domestic journals. The moderating variables hypothesized in this study included age groups of participants; depressive symptoms; and frequency, intensity, time, type, and duration of the intervention. The overall effect size of physical activity on depression was moderate (0.56 [95% CI: 0.39 to 0.91]). Specifically, physical activity was slightly more effective in reducing depression in participants with an 18-64 age group compared to older people over 65 years old, while it was most effective for participants without depressive symptoms compared to participants with mild and severe symptoms. Further, the subgroup analysis revealed that performing two times a week for 30 to 60 min with progressive intensity for 1-8 weeks may be the most effective for Koreans. The results of this study can provide guidelines for the most effective physical activity program for Koreans.

Impact of COVID-19 on consumers' impulse buying behavior of fitness products: A moderated mediation model.

During the COVID-19 pandemic, consumers are found to be more impulsive to purchase fitness products online. Accordingly, the purpose of this study was to investigate a moderated mediation model of consumers' perception of COVID-19 and impulse buying behavior through fear moderated by income. A total of 608 responses were collected from consumers in the United States, and this study employed partial least squares structural equation modeling (PLS-SEM) to examine the hypothesized relationships in the research model. The results showed that the perception of COVID-19 had a positive influence on fear, which in turn led to impulse buying behavior of fitness products. Moreover, consumers' income levels negatively moderated the positive relationship between fear and impulse buying behavior. The findings contribute to a better understanding of consumers' behavior and offer practical implications that enable marketers and retailers to predict consumers' behavior during the COVID-19 pandemic.

Signaling-transduction pathways required for ex vivo expansion of human limbal explants on intact amniotic membrane.

PURPOSE: Ex vivo expansion of limbal epithelial progenitor cells on amniotic membrane (AM) without 3T3 fibroblasts is a new surgical approach to treat limbal stem cell deficiency. Such expansion requires NGF-TrkA-mediated signaling, and this study was conducted to delineate the downstream signaling pathways. METHODS: The human corneolimbal ring was cut into explants and cultured on intact human AM. At day 0 or 10, low-molecular-weight inhibitors were added, whereas the control group received dimethyl sulfoxide (DMSO). The epithelial outgrowth rate was monitored for 17 days, and the epithelial cells were collected for Western blot analysis. RESULTS: In the control, most expansion of human limbal epithelial cells started from the limbus from days 5 to 7 and reached approximately 80% confluence at day 17. Compared with the control, the outgrowth was completely inhibited by 50 microM LY294002 or 50 microM SR13668 and was significantly suppressed by 10 microM U0126, but was not affected by 10 microM of either SB203580 or JNK inhibitor 1. The inhibition of outgrowth by LY294002, SR13668, and U0126 was reversible. Western blot analysis showed that phosphorylation of Akt and FKHRL1was abolished by LY294002 and SR13668, but downregulated by U0126, which also abolished phosphorylation of p44/42 mitogen-activated protein kinase (MAPK). The phosphorylation of p38 and JNK MAPK were downregulated or abolished during ex vivo expansion. CONCLUSIONS: Ex vivo expansion of human limbal epithelial progenitor cells on intact AM is mediated by the survival signaling pathway mediated by PI3K-Akt-FKHRL1 and by the mitogenic MAPK pathway mediated by p44/42 at the expense of p38 and JNK MAPK.
