Usually, both external environmental factors and internal psychological factors affect the self-efficacy of athletes returning to sports after an injury. Based upon COR theory, this study investigated mindfulness interventions’ effects on competitive state anxiety and burnout in injured athletes who are returning to sports. The study was conducted in South China from March to April 2022. The snowball and convenience sampling methods were used to select high-level sports teams’ injured athletes returning to sports, and a questionnaire survey was administered, from which 433 valid samples were obtained. Amos v. 26 was used to analyze the data. The results showed that mindfulness has a significant negative effect on competitive state anxiety and burnout, such that after strengthening the mindfulness intervention, athletes’ competitive state anxiety and burnout decreased and regulatory emotional self-efficacy increased. Further, this study indicated that athletes are prone to negative emotions after injury, and among athletes who returned to sports after injury, those with mindfulness interventions reported lower levels of competitive state anxiety and burnout. Hence, the study demonstrated that mindfulness can improve regulatory emotional self-efficacy in injured athletes who are returning to sports by reducing competitive state anxiety and burnout.

This study aims to understand the state of emotional exhaustion of Chinese doctors during the COVID-19 pandemic, and explore the role of sports involvement in enhancing doctors’ regulatory emotional self-efficacy, reducing stress perception, and alleviating emotional exhaustion. Finally, report the existing problems and make recommendations to the government and hospitals. The researchers constructed a cross-sectional questionnaire survey to collect data. From March to April 2022, using the snowball and convenience sampling methods, a total of 413 valid questionnaires were collected from 13 hospitals in Hunan Province. AMOS 23.0 was used to construct a structural equation model (SEM) with the bootstrapping approach to verify the proposed hypotheses. Doctors with more sports involvement exhibited higher levels of regulatory emotional self-efficacy and lesser perceived stress. Doctors who exhibited higher regulatory emotional self-efficacy had lesser perceived stress. The relationship between sports involvement and emotional exhaustion was mediated by perceived stress and/or regulatory emotional self-efficacy. Therefore, the government and hospitals should strengthen the depth and intensity of implementing the “National Fitness Program” at the hospital level, instead of just holding short-term activities with a small number of participants, but to cover all medical staff with fitness opportunities.
