ObjectiveThis study aimed to analyze the influence of cheerleading on female college students’ physical self-esteem and mental health.Materials and MethodsIn total, 63 female college students from the University of Electronic Science and Technology of China were trained in cheerleading for 16 weeks. The scores of each sub-field of physical self-esteem and psychological symptoms were analyzed by using Physical Self-Perception Profile (PSPP) and Symptom Checklist 90 (SCL-90), respectively, at 0 and 16 weeks of the experiment.ResultsAfter 16 weeks of cheerleading exercise, female college students had significant differences in physical attractiveness (T = 4.18), physical quality (T = 4.39), and physical self-worth (T = 3.35) before and after the experiment (P < 0.01). There were significant differences in physical condition (T = 3.87) and athletic ability (t = 2.88) before and after the experiment (P < 0.05). Somatization (T = 6.485), obsessive-compulsive symptoms (T = 11.716), interpersonal sensitivity (T = 10.077), depression (T = 8.403), anxiety (T = 10.767), hostility (T = 10.866), terror (T = 9.260), paranoia (T = 10.414), psychosis (T = 9.610), sleep and eating disorders (T = 9.323), total symptom index (T = 13.245), and mean score of positive symptoms (T = 12.237) were significantly different (P < 0.01).ConclusionCheerleading can significantly improve the level of female college students’ physical self-esteem, especially the self-esteem level of physical attractiveness, physical quality, and physical self-worth. They also experienced significant improvement in their psychological disorders, especially somatization, depression, and sleep and eating disorders, which effectively improved their overall mental health.

With the development of information technology, the application of a new generation of information technologies, such as big data, Internet Plus, and artificial intelligence, in the sports field is an emerging, novel trend. This paper examined the relevant research results and literature on physical education, computer science, pedagogy, management, and other disciplines, then used a self-made questionnaire to investigate the physical health status of Chinese college students. The big data were subsequently analyzed, which provided a scientific basis for the construction of an intelligent governance system for college students' physical health. Intelligent devices may be used to obtain big data resources, master the physical sports development and psychological status of college students, and push personalized sports prescriptions to solve the problems existing in college students' physical health. Research shows that there are four reasons for the continuous decline in Chinese college students' physical health levels. These are students' lack of positive exercise consciousness and healthy sports values (85.43%), a weak family sports concept and lack of physical exercise habits (62.76%), poor implementation of school sports policies (55.35%), and people's distorted sports value orientation (42.27%). Through the connecting effect of data, we can bring together the positive role of the government, school, society, family, and students so as to create an interlinked impact to promote students' physical health. The problems of insufficient platform utilization, lack of teaching resources, lagging research, and insufficient combination with big data in the intelligent governance of physical health of Chinese college students can be solved by building an intelligent governance system of physical health. Such a system would be composed of school infrastructure, data resources and technology processing, and intelligent service applications. Among these, school infrastructure refers to the material foundation and technical support. The material foundation includes perceptions, storage, computing, networks, and other equipment, and the technical support includes cloud computing, mobile Internet, the Internet of Things, artificial intelligence, and deep learning. Data resources refer to smart data, such as stadium data, physical health management data, and students' sports behavior data, which are mined from data resources such as students' physical development, physical health, and sports through big data technology and intelligent wearable devices. Intelligent managers provide efficient, intelligent, accurate, and personalized intelligent sports services for college students through data resource value mining, venue space-time optimization, health knowledge discovery, sports prescription pushes, etc. Finally, we put forward the development strategy for further deepening and improving the big data-driven intelligent governance system for college students' physical health. The intelligent governance system of physical health driven by big data and its development strategy can not only accurately guide and improve the physical health level of college students but also realize integrated teaching inside and outside physical education classes.

Based on the analysis of the status quo of the development of sports industry, this paper studies the development opportunities and structural changes of sports industry under the background of new information technology. Objective to explore the development opportunities and structural transformation of sports industry under the background of new information technology, broaden the research field of sports industry, and provide references for the development planning or policy formulation of sports industry. According to this study, the current development status of sports industry is not optimistic, which is mainly reflected in the weak willingness of sports consumption, the shortage of sports venues and facilities, the lack of talents in sports industry, and the lack of in-depth integration with new information technology. Under the background of new information technology, the development opportunities of sports industry are mainly reflected in three aspects, that is, new information technology promotes sports industry to seize opportunities and expand markets, innovate the operation mode and operation mode of sports industry, and change the service platform and service system of sports industry. The structural transformation of the development of sports industry is reflected in the new competition system, new technology system, new consumption structure and new business trend. In the context of new information technology, it is necessary to analyze the opportunities and challenges faced by the sports industry more deeply, put forward more specific operational development countermeasures, and build a new sports industry development ecosystem and business model, in order to promote its sound development.

The construction of college physical education network teaching resources is based on teaching needs, guided by curriculum innovation, aimed at integrated teaching, and follows relevant national policies to realize the development and sharing of resources. By using the methods of literature, questionnaire, data analysis and action research, this paper studies the related problems, expounds the concept, value, significance and basic structure of the network teaching resource database of physical education in colleges and universities, and studies its construction and application status. On the basis of learning from the good practices of other schools and other disciplines, and taking our school as an example, we have established a physical education network teaching resources database with strong pertinence and practicability, namely AI sports. It basically covers the main courses of physical education and can meet the teaching needs of teachers and students. It not only enriches the means of physical education teaching, but also realizes the integration of physical education teaching and plays an active role in physical education teaching.

China is actively promoting the "Internet +" action plan, which will have a profound impact on all walks of life. On the basis of analyzing the development status of China's leisure sports industry, it analyzes the opportunities and challenges brought by "Internet +" to China's leisure sports industry from the perspective of opportunities and innovations, and proposes "Internet +" to promote the transformation of China's leisure sports industry development mode. The path and the construction of a new ecosystem of China's leisure sports industry in the era of "Internet +" will provide a reference for China's leisure sports industry to actively grasp the opportunity of the "Internet +" action plan and seek its own development.
