Introduction The life expectancy of Chinese population is increasing continuously, and whether the proportion of healthy life is increasing simultaneously has become the focus of attention. Healthy life expectancy is an important index to measure life in old age. We aim to estimate the impact of physical exercise on healthy life expectancyof the elderly in China. Methods Based on the data from Chinese Longitudinal Healthy Longevity in the 2002-2018, We first calculate the healthy life expectancy of the elderly in China, and then use channels to test the influence of physical exercise on healthy life expectancy of the elderly. We first estimate the regression coefficient of physical exercise on healthy life expectancy, then add channel variables affecting healthy life expectancy and further calculate the contribution of channel variables to healthy life expectancy. Finally, the difference in healthy life expectancy between the elderly with or without exercise habits matched by propensity score. Results The influence of physical exercise on the healthy life expectancy of the elderly is always significant. The healthy life expectancy of the elderly with physical exercise habits is 3.45 years longer than that of the elderly without physical exercise habits, and the proportion of healthy life expectancy is also 9.5% higher. The contribution of smoking, drinking, physical exercise, social interaction and medical service accessibility to healthy life expectancy is 1.05%, 1.05%, 3.16%, 2.11% and 1.05%, respectively, and the total contribution is 5.26%. Discussion The relationship between physical exercise habits and healthy life expectancy/proportion of the elderly is stable. The healthy life expectancy of the elderly with exercise habits is longer than that of the elderly without exercise habits, and the proportion of healthy life expectancy is significantly higher than that of the elderly without exercise habits. Subdividing the years of exercise habits and further considering the health level in the previous period, the healthy life expectancy of the elderly who do not exercise (especially in the state of not exercising in both periods) is the shortest. The healthy life expectancy of the elderly with short exercise habits and no medical insurance and chronic diseases is at a disadvantage. Health behavior (smoking and drinking), social participation (participation in various activities) and access to timely medical services are channel variables of physical exercise affecting healthy life expectancy. Social participation behaviors such as physical exercise and other activities have a relatively large contribution to healthy life expectancy and its proportion of the elderly. Personal health behavior and medical services have a relatively small impact on it. The healthy life expectancy of rural female elderly and urban male elderly is the shortest among the elderly with exercise habits. This paper further confirms the positive effect of physical exercise

Introduction Table tennis originated in the West, but developed into the "national ball" in China, becoming the most important sport in China. But in recent years, with the development of the information age and Chinas greater emphasis on sports, students now have access to more sports. Therefore, the purpose of this study is to investigate the identity status and identity elements of table tennis in Chinese students. Methods PPS sampling of students from junior high school to doctoral student group was conducted by using questionnaire survey. A total of 2375 students from 52 schools were investigated, including 1142 students from 25 middle schools, 913 students from 20 high schools, and 320 students from 7 universities. Male students accounted for 56%. 2186 valid questionnaires and 189 invalid questionnaires were collected. SPSS 26.0 was used for descriptive statistical analysis. Results 1) The degree of cultural recognition of table tennis and the number of international gold MEDALS won by Chinese students (r=0.57, p＜0.01), national policy orientation (r=0.32, p＜0.01), understanding degree of Chinese table tennis history (r=0.25, p＜0.01), participation degree of table tennis (r=0.18, p＜0.01) Significant positive correlation; 2) 81.2% of the students believe that table tennis is the most important sport in China, and 78.5% of the students know about Chinas table tennis diplomacy; 3) In terms of sports other than table tennis, 52.3% of students prefer China to win the world championship in football, followed by 16.8% in basketball and 10.3% in volleyball; 4) 73.0% of the students believe that even if China is unique in their desired sports, the special status of table tennis in China cannot be shaken. Discussion First of all, it needs to be clearly pointed out that since China has 293 million students at all levels of education, it is impossible to conduct a large-scale survey of the whole country. In addition, primary school students are not included in the survey due to their limited knowledge range and language comprehension. As can be seen from the survey data, table tennis is undoubtedly the most important sport recognized by the Chinese people. Moreover, as the Chinese government attaches great importance to table tennis, students can contact table tennis through various channels and media, and 72% of students have public table tennis facilities near their residence. Chinese ping-pong diplomacy has also become an interesting topic for teachers and students in Chinese history textbooks. Finally, Chinese students have a high degree of cultural confidence in table tennis. Even though football is the "worlds first sport", more students still believe that table tennis is irreplaceable.

Introduction Les Mills International (LMI) is a global franchise fitness community that strives to create life changing fitness experiences. LMI produce ready-to-teach choreographies to some 140.000 worldwide instructors who teach approximately six million exercisers weekly with class formats such as BodypumpTM and BodybalanceTM. LMI target laypeople to turn their hobbies into professions by becoming instructors for the brand, which creates a diverse global community of enthusiasts. Despite LMI being a consequential distributor of pre-choreographed classes, little is known about the motivations for being a LMI instructor. Therefore, this study aims to contribute new knowledge about what aspects of LMI instructorhood seem to be most important for the participating instructors and how this is related to age, classes-per-week-load, gender, and instructor status (junior versus senior). Methods We use a quantitative elicit approach with a Likert scale questionnaire (N = 332) that was distributed to the global LMI community in 2020 (January to March) through LMI social media groups and LMI official newsletters. The questionnaire elicits LMI instructors’ reactions toward LMI’s philosophy, characteristics of LMI instructors, and perceived commitment to the profession. Scales were extracted using factor analysis, and based on these scales, t-tests and ANOVA were used to explore differences across age, number of classes held per week, gender, and LMI instructor level. Subsequently, a structural equation modeling analysis was used to analyze the interrelationship between the scales. Results The analysis allows the authors to distillate three valid and reliable scales: community, physical perfection, and serious leisure. Respondents report the highest value on the variable serious leisure (M = 5,09, SD = .83), thereafter, physical perfection (M = 4,72, SD = .98), and lastly the variable community (M = 4.24, SD = 1.17). The results also show that there were significant differences for community, physical perfection, and serious leisure across classes held per week, professional seniority, and age. Lastly, the structural equation modeling analysis showed a good model fit in predicting serious leisure through community and physical perfection. Discussion The scale community shows that instructors value sociable aspects (e.g., meeting colleagues, following LMI colleagues on LMI social media), while the scale physical perfection shows the high value that body work has (e.g., working on a lean physique through the teaching of classes). Lastly, serious leisure says something about the commitment that instructors show toward LMI (e.g., I cannot imagine a life without LMI), and perceived benefits (having fun and challenging physical limits). In sum, instructors find meaningfulness through working on their own and others physiques, which extends to research by presenting a merging of altruism and individualism as motivational factors.
