Previous studies have implied that physical activity profoundly influences interpersonal adaptation. However, this effect and its mechanisms have not been directly verified, especially for adolescents. This study examines the association between physical activity and interpersonal adaptation in adolescents through self-esteem and psychological resilience after the coronavirus disease 2019 (COVID-19) pandemic. Participants included 542 Chinese adolescents (aged 13–18 years; 242 boys and 300 girls). Adolescents in China anonymously completed a series of questionnaires, including the PARS-3 Scale of PE Activity Grade (PARS-3), the Self-esteem Scale (SES), the Resilience Scale for Adolescents (RSCA), and the Interpersonal Adaptation Scale. The results showed that physical activity positively correlated with self-esteem, psychological resilience, and interpersonal adaptation. Additionally, self-esteem and psychological resilience serially mediated the impact of physical activity on interpersonal adaptation. The findings highlight the positive impact of physical activity on adolescent interpersonal adaptation by strengthening positive psychological resources in the post-pandemic era.

Mindfulness has long been concerned and emphasized by scholars in the field of psychology, but there is still a lack of research on mindfulness in management in China. In this study, a questionnaire survey was conducted among 483 employees in the new media industry in Beijing, Shanghai, Guangzhou, Shenzhen, and Hangzhou, China. After modeling and analysis, it was found that employee mindfulness has a positive influence on innovative behavior. Employee mindfulness and innovative behavior are mediated by positive emotions. Employee mindfulness and innovative behavior are mediated by work engagement. Employee mindfulness and innovative behavior are mediated by a chain of positive emotions and work engagement. Enterprise managers should improve the level of mindfulness of employees in the new media industry through mindfulness training and courses for mindfulness training, create an organizational environment that can arouse positive emotions and improve the positive emotions of employees, pay attention to arousing the enthusiasm of the staff, and promote the innovative behavior of staff while enhancing work engagement.
