The World Health Organization has identified nervous system diseases as one of the biggest public health problems, including autism spectrum disorder (ASD). Considering the extensive benefits of physical activity (PA), the literature on the PA research of ASD has increased each year, but there is a lack of bibliometric analyses in this field. To investigate the research achievements worldwide, this paper adopts bibliometrics to analyze the trend in the academic literature on the PA research of ASD published from 1980 to 2021. The documents were retrieved from the Web of Science database, and the search strategy was to combine the keywords related to “physical activity” and “autism spectrum disorder” by using the Boolean operator tools “OR” and “AND” in the title. A total of 359 English documents were retrieved. Microsoft Excel, Data Wrapper, VOSviewer, and Biblioshiny were used for the visual analysis. We found that the number of published documents increased the fastest from 2017 to 2021, which may be due to the promulgation of the Global Action Plan for Physical Activity 2018–2030 and the influence of COVID-19 on the world. The United States and the University of California systems are in the leading position in this field. Cooperation among countries with different levels of development will help to jointly promote the PA research progress on ASD. The focus themes include “individual effect”, “social support” and “activity dose”. The analysis of the frontier topic points out that researchers are paying increasing attention to how to improve the health and physical fitness of this group through PA. This research clearly puts forward a comprehensive overview, theme focus, and future trends in this field, which may be helpful to guide future research.

Fundamental motor skills (FMS) are the foundation of children's movement, requiring tailored training and guidance for development. As an emerging training method, functional training is optimistic in promoting the development of children's fundamental motor skills. However, current studies have not assessed the effect of functional training on fundamental motor skills. This review aims to address this gap by evaluating the effects of functional training on fundamental motor skills. A search was conducted in five databases: PubMed, Scopus, ProQuest, Web of Science, and SPORT Discus, from January 2000 to June 2023. This search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The results of the search identified a total of twenty-six articles. Improvements were primarily demonstrated in the three main areas of fundamental motor skills: locomotor skills (n = 17), balance skills (n = 10), and object control skills (n = 2). The results suggest that functional training programs can improve children's fundamental motor skills. Existing evidence also concludes that functional training significantly impacts locomotor and balance skills, whereas further research is required to confirm its positive effects on object control skills.

Alzheimer’s disease (AD) is the most common cause of dementia worldwide, posing a considerable economic burden to patients and society as a whole. Exercise has been confirmed as a non-drug intervention method in the related literature on AD. However, at present, there are still few bibliometric studies on AD exercise research. In order to fill the gap, this paper aims to intuitively analyze the growth in AD exercise literature published from 1998 to 2021 using bibliometrics, providing historical insights for scientific research circles. The main source of literature retrieval is the Web of Science database. Using the Boolean operator tools “OR” and “AND” combined with keywords related to “exercise” and “Alzheimer’s disease”, we conducted a title search and obtained 247 documents. Using Microsoft Excel, Datawrapper, and Biblioshiny, this study carried out a bibliometric analysis of countries, institutions, categories, journals, documents, authors, and keyword plus terms. The study found that the number of papers published from 2016 to 2021 had the greatest increase, which may have been influenced by the Global Dementia Report 2015 and COVID-19. Interdisciplinary cooperation and the research results published in high-scoring journals actively promoted research and development in the AD exercise field. The United States and the University of Minnesota system play a central role in this field. In future, it will be necessary to explore the effectiveness and feasibility of multi-mode interventions on an active lifestyle, including exercise, in different groups and environments worldwide. This study may provide a direction and path for future research by showing the global overview, theme evolution, and future trends of research results in the AD exercise field.

Sports facilities are a crucial physical safeguard and means of sustaining sporting activities. The steady and healthy development of sports facilities can promote the sustainable development of the social economy. In order to explore the coordination status and influencing factors between sports facilities construction and the social economy, this paper built a coupling coordination evaluation index system and dynamic factor index system for the sports facilities construction and social economy development by using the entropy method, coupling coordination model and random effect model. This paper assessed the comprehensive level, coupling coordination relationship, and influencing factors of the sports facilities and social economy development of nine cities in the Fujian Province across China from 2016 to 2020. The results show the overall level of sports facilities construction in Fujian is better than the social economy development, and the two systems are interacting with each other. The level of coupling and coordination gradually changes from good coordination to quality sustainable coordination. The coupling coordinated relationship between the two systems is developing in a positive way. In addition, industrial development, the level of urban development, and environmental development as influencing factors have a clear positive effect on the degree of coupling coordination. This study provides several recommendations for cities to achieve sustainable coordinated development. This paper also may provide a direction and path for future research.

The study aims to explore the relationship between physical activity (PA) levels and externalizing problem behaviors among Chinese adolescents, to inform personalized intervention strategies based on scientific evidence. This cross-sectional study was conducted from November 10 to December 15, 2024, among middle and high school students in Sichuan, Guangdong, Shandong, Henan, and Jiangxi provinces in China. A total of 1,718 valid questionnaires were collected (mean age = 14.32 years, SD = 1.45). The sample included 761 middle school students and 957 high school students, PA levels were assessed using the International Physical Activity Questionnaire-Short Form (IPAQ), and externalizing problem behaviors were measured using the Youth Self-Report (YSR) scale. Latent profile analysis (LPA) was employed to classify PA levels and externalizing problem behaviors, and multivariate logistic regression was used to examine the association between demographic variables and externalizing problem behaviors. The study indicated that: (1) Adolescents in suburban areas exhibited the highest scores in externalizing problem behaviors and PA levels (p < 0.05), and externalizing problem behaviors significantly increased with age (p < 0.001); (2) Externalizing problem behaviors were categorized into three latent classes: low-problem group (75.1%), moderate-problem group (13.1%), and high-problem group (11.8%); (3) The high-problem group scored the highest across all indicators, especially in aggressive behaviors, whereas the low-problem group had the lowest levels of externalizing behaviors; (4) Multivariate logistic regression revealed that higher PA levels significantly reduced the likelihood of moderate-problem (OR = 0.71, p < 0.001) and high-problem behaviors (OR = 0.44, p < 0.001). Higher levels of physical activity are associated with reduced externalizing problem behaviors in adolescents. Based on these findings, it is recommended to incorporate regular physical activity into behavioral intervention programs and develop personalized support strategies tailored to adolescents’ specific characteristics.

Traditional assessment methods in physical education often emphasize final grades, lacking real-time monitoring and feedback during the learning process. To address this limitation and enhance the formative evaluation of student performance, this study proposes a real-time assessment system for Baduanjin instruction in physical education, utilizing a commercially available inertial measurement unit-based motion capture device. The system was developed in four stages. First, a dataset was created by recruiting 20 university students and one expert physical education instructor. Participants were asked to perform standardized Baduanjin routines while wearing wireless inertial measurement unit sensors on key body joints. The collected kinematic data, sampled at 100 Hz, included joint angles and movement trajectories. Second, preprocessing and feature extraction techniques were applied to the raw data to construct a labeled dataset for training. Third, supervised machine learning algorithms were used to build models for motion type recognition and motion accuracy evaluation. Model performance was assessed using cross-validation and compared with expert evaluations. Finally, a user-facing formative assessment system was developed and tested in a controlled classroom environment. The system demonstrated a high motion recognition accuracy of 99.77%, and the correlation coefficient between system-assessed motion accuracy and expert ratings exceeded 0.80, indicating strong validity. The results demonstrate that the formative assessment system built on inertial measurement unit is appropriate for the Baduanjin physical education.
