The influence of national health level in the stability and sustainable development of national society is increasingly prominent. The purpose of this study is to examine whether, when, and how national fitness policies exert influence on national health. Panel data from 2008 to 2017 of 30 Chinese provinces (cities) (except the Tibet autonomous region) were used to systematically reveal the direct impact of national fitness policies on national health and its characteristics in different regions, as well as the interaction mechanisms of human capital and finance health expenditures in public sports. This study found that first, national fitness policies had a positive effect on adult health. Second, sports human capital weakens the health effect of national fitness policies, while public finance health expenditures strengthen this effect. Lastly, the health effect of national fitness policies varies significantly across regions due to uneven regional economic development, and the differences in the effects on different age groups (adults and children) are equally pronounced. This study suggests that national fitness public service system and diverse national fitness plans improving national health level are important for a new dynamic balance and high quality coordinated development in both Chinese economic growth and social welfare.

The purposes were to evaluate kinetics in lower limbs using single leg countermovement jump (SLCMJ) and to identify the differences in SLCMJ kinetics between sprinting fast players and sprinting slow players in elite university female soccer players. Seventeen participants at the national tournament level completed the survey. SLCMJ and 30 m sprinting tests were performed. A force-plate was used to collect the data of the SLCMJ test. Significant differences of concentric maximum rate of force development (RFD), concentric RFD, concentric RFD/body weight (BW), peak net takeoff force/BW, peak power, and peak power/BW existed between both legs during the SLCMJ among all the participants. For further analysis, the participants were divided into fast group and slow group based on sprinting performance. Significant differences existed between the two groups in concentric peak velocity (nondominant, p = 0.028) and vertical velocity at takeoff (nondominant, p = 0.021). Concentric maximum RFD (p = 0.036) was significantly different between both legs in the slow group. Among elite university female soccer players, the players who presented more increased asymmetry of kinetic characteristics of jumping, also showed weak sprinting performance. Moreover, the players presented the best performance in velocity of the jumping variables and also had the best sprinting performance. Coaches and players should focus on keeping inter-limb balance and developing jumping velocity to improve sports performance. In future, the cause-and-effect relationship between jumping and sprinting should be identified.

The impact and working mechanism of the national Healthy Cities pilot policy on the upgrading of the industrial structure remain foggy. This study takes China’s first batch of Healthy Cities under the pilot policy in 2016 as a natural experiment and builds a DID model based on the panel data of 280 prefecture-level cities from 2012 to 2019 to explore the impact of the Healthy Cities pilot policy on the industrial structure, wherein the impact tests and regional heterogeneity analysis are carried out accordingly. It is found through the study that the Healthy Cities pilot policy significantly contributes to industrial structure upgrading, especially for cities in the eastern and central regions. Further research on the impact mechanism shows that the Healthy Cities pilot policy facilitates industrial structure upgrading through technological innovation and green total factor productivity. Supported by the research results, this study argues that it bears great significance on the sustainable development of China’s economy as well as the health and well-being of the people to continually carry out the Healthy Cities pilot work and fully explore the mediating mechanism of the multi-faceted pilot policy on the optimization and upgrading of industrial structure, so as to promote the transformation of the health industry in different regions according to respective local conditions.

Background: Physical Activity Participation is closely associated with functional health among older women, but this participation is often constrained by multiple perceived barriers. The aim of this study was to examine the association between Perceived Exercise Barriers (PEB) and Basic Activities of Daily Living (BADL) among older women in China, investigate the indirect association of Physical Activity Participation (PAP) in this relationship, and examine the moderating role of Community Sports Facility Accessibility (CSFA) in the association between PEB and PAP. Methods: Using data from the 2023 China Longitudinal Aging Social Survey (CLASS), this cross-sectional study included 5027 women aged 60 years and above. Perceived Exercise Barriers were operationalized as the sum of 18 dichotomous barrier indicators. Basic Activities of Daily Living were measured by summing 11 items assessing daily living functions. Physical Activity Participation was calculated by summing scores across three dimensions: exercise frequency, duration per session, and exercise intensity. Community Sports Facility Accessibility was measured according to the number of available types of community sports resources. A conditional indirect association model was estimated using the SPSS PROCESS macro, and confidence intervals were obtained through the bootstrap method (5000 resamples). Results: Perceived Exercise Barriers were significantly and negatively associated with Basic Activities of Daily Living (B = −0.103, p < 0.001) and Physical Activity Participation (B = −0.471, p < 0.001) among older women. Physical Activity Participation showed a significant but relatively small indirect association between Perceived Exercise Barriers and Basic Activities of Daily Living (indirect effect = −0.034, 95% CI −0.044 to −0.024). Furthermore, Community Sports Facility Accessibility significantly moderated the association between Perceived Exercise Barriers and Physical Activity Participation (interaction term B = 0.094, p < 0.001). Higher levels of facility accessibility were associated with a weaker negative association between Perceived Exercise Barriers and Physical Activity Participation, accompanied by a reduced absolute value of the conditional indirect association. Conclusions: This study identified a potential behavioral pathway linking Perceived Exercise Barriers, Physical Activity Participation, and Basic Activities of Daily Living among older women, and demonstrated the conditional role of Community Sports Facility Accessibility in this association. The findings suggest that improving functional health among older women may require attention to individual perceived barriers, behavioral participation, and supportive community environments.
