(1) Background: Aging is a global phenomenon, and China’s aging is extensive and rapid and already at the middle to upper level worldwide. Promoting social interaction and increasing positive psychological qualities in individuals are key components in helping people adapt to the physical and mental changes of the aging process. Among them, how middle-aged and older adults improve their physical and mental health through physical activity is of great concern. (2) Methods: This study measured the physical activity of 2721 middle-aged and elderly square dance participants across China, and structural equation modeling was applied to explore the relationship between square dance exercise and group cohesion as well as the role of perceived social support and psychological capital. (3) Results: The results showed that (a) square dance exercise positively predicts group cohesion among middle-aged and older adults. (b) Perceived social support and psychological capital mediate the relationship between square dance exercise and group cohesion, and the mediating role consists of three pathways: perceived social support alone, psychological capital alone, and perceived social support-psychological capital chain mediation. (c) The mediating effect of psychological capital alone is greater than the mediating effect of perceived social support alone and the mediating effect of the perceived social support-psychological capital chain. (4) Conclusions: This study provides support for the theory and practice of square dance exercise and intervention guidance for increasing positive psychological qualities and group dynamic levels in middle-aged and older adults.

As the most popular sport among middle-aged and elderly women in China, square dancing has both physical and psychological benefits for menopausal women. Previous studies have shown that square dance exercises can promote the physical health of older women, but there is a lack of research on the influence of middle-aged and elderly women on mental health and mediating variables. Therefore, this study starts with one of the important indicators of mental health—positive affects, aiming to explore the impact of square dance on the positive emotions of elderly women and further explore the mediating mechanisms involved. We send out The Physical Activity Rating Scale, the Positive and Negative Affect Scale, the Connor-Davidson Resilience Scale, and the Satisfaction With Life Scale to a total of 2311 middle-aged and elderly women. SPSS 23 software and PROCESS were used to perform regression analysis and establish mediation models. Modeling results show square dance exercises could positively predict positive affect through the chain mediating effect of psychological resilience and life satisfaction. The results of this study are of great significance for promoting the extensive participation of middle-aged and elderly women in sports and protecting their mental health.

Background: COVID-19 has brought people many negative emotions, such as fear and anxiety about the epidemic. However, when peo-ple in different countries face the COVID-19 epidemic, the impact is also different due to different cultural and sports hab-its. Therefore, this study compares China and Poland’s sports motivations in the face of COVID-19 anxiety to find out the cultural differences behind them.Participants and procedure: In the study were N = 674 participants (female n = 407, male n = 260, other n = 4). Their average age was M = 29.86, SD = 11.03. There were n = 381 participants in the Chinese sample, and n = 293 in Polish. The scales used for the purpose of the study were the Inventory of Physical Activity Objectives (IPAO) and the Coronavirus Anxiety Scale (CAS).Results: The study results showed that the increased level of COVID-19 anxiety changed selected motives for physical activity, and different changes of motives characterized women and men as well as people of different ages. As predicted in the study model, culture was the moderator of the shifts of the selected motives.Conclusions: The understanding of what motivates individuals to participate in sport seems to have significant value, especially for health practitioners and researchers to design appropriate interventions and programs to increase activity.

Objective: Mindfulness can help athletes better regulate their emotions, and analyzing personality traits may help identify those who would benefit more from psychological intervention activities to optimize subsequent training effects. This study sought to examine the effects of mindfulness training on athletes’ competition anxiety and to consider the role of personality traits. Methods: Fifty athletes (mean age = 21.87 years, SD = 1.62; 23 females and 27 males) were randomly assigned to a mindfulness group (n = 23), which received 8 weeks of mindfulness training, and a control group (n = 27) receiving no intervention. The athletes’ personality traits, mindfulness level, and competition anxiety were measured according to the study plan before and after mindfulness training, and at an 8-week follow up. Results: Compared with the control group, mindfulness training had a positive effect on the level of mindfulness and self-confidence in the mindfulness group, as well as a greater improvement in cognitive/somatic state anxiety. Improvements remained stable from the end of training to follow up. Additionally, athletes with high activity and high extraversion had more improvement in mindfulness levels and cognitive/somatic state anxiety, respectively, while athletes with low neuroticism demonstrated greater improvement in self-confidence. Conclusions: Mindfulness training helps to reduce athletes’ competition anxieties, and personality traits might affect the improvement effect to a certain extent, which provided a reference for optimizing mindfulness training and developing more personalized psychological training for athletes who display certain personality traits.

Background: Chinese square dance has become well known worldwide in recent years, and most participants are women who dance with a group in their communities. In particular, middle-aged women may have physical and mental health problems, and participating in square dance may increase women’s positive subjective well-being and decrease their negative emotions, which may improve their health over the long term. In addition, participating in square dance can promote group cohesion. Our study aimed to examine the relationship between the subjective exercise experience of participating in square dance and group cohesion and whether some variables (e.g., age, education, duration, income level, and work) play a role as mediators in the association with subjective exercise experience and group cohesion.Methods: In total, 1,468 Chinese women from 31 provinces and 82 cities participated in this study by completing an online questionnaire. The questionnaire consisted of a subjective exercise experience questionnaire and a group environment questionnaire. We analyzed the collected data and built a statistical model.Results: (a) Square dance satisfied women’s physical and psychological needs partly; (b) positive well-being (PWB) was positively correlated with group cohesion, and fatigue was negatively correlated with group cohesion; and (c) the income level was a partial mediator of the relationship between group cohesion and subjective exercise experience.Conclusion: Chinese women have different motivations for participating in square dance. Because this activity can help meet women’s physical and psychological needs, an increasing number of individuals worldwide participate in square dance. As women’s subjective well-being increases, group cohesion increases, and vice versa. Moreover, the subjective exercise experience remains a significant predictor of group cohesion after including income level as a mediator, suggesting that the model indicates partial mediation.

A strong sociocultural context could affect an individual’s aesthetic standards. In order to achieve a socially recognized ideal appearance, obligatory exercisers might increase dieting behavior when exercise actions are disturbed, thereby placing the individual at risk of eating disorders. The current study mainly examined the relationship between obligatory exercise and eating attitudes during the COVID-19 pandemic, and considered the mediating role of externalized sociocultural attitudes towards appearance between the two. A total of 342 participants (175 females, 167 males) from various regions of China were invited to fill out the questionnaires including the Obligatory Exercise Questionnaire, the Sociocultural Attitudes Toward Appearance Questionnaire-3, and the Eating Attitudes Test. In total, 51.5% of the participants presented symptoms of an obligatory exercise behavior. Among them, males, young adults, and the participants with lower BMI had higher OEQ scores, whereas females and young adults had higher EAT-26 scores. Meanwhile, 9.4% of the participants might have had an eating disorder. The OEQ score was positively correlated with the EAT-26 total score as well as SATAQ-3 ‘Pressures’ and ‘Information’ subscales. In addition, the EAT-26 total score was positively correlated with the SATAQ-3 ‘Pressures’ and ‘Information’ subscales. Externalized sociocultural attitudes towards appearance served as a mediator between obligatory exercise behavior and eating attitudes, and the mediation effect accounted for 56.82% of the total effect. Obligatory exercise behavior may have an indirect effect on eating attitudes through sociocultural attitudes towards appearance. Given the sociocultural information and pressures, in order to maintain or pursue an ideal appearance, many people tend to keep a pathological diet. Thus, forming a positive and healthy social aesthetic orientation is beneficial in helping obligatory exercisers to develop reasonable eating habits.
