Sport is a type of comprehensive activity that the human body consciously engages in to improve physical fitness. Proteomics is a comprehensive technology dedicated to the study of all protein profiles expressed by a species, individual organ, tissue, or cell under specific conditions and specific times. Proteomics is a science that studies the protein composition of cells, tissues, or organisms and their changing laws with proteomics as the research object. Related technologies are now widely used in sports and other fields. The purpose of this article is to study myocardial proteomic technology and its application in sports. During the research process, the main methods used in this study are literature survey and controlled experiment. The results achieved and the problems in this field, followed by selecting 30 SD rats into 3 groups for control experiments. The results of the study showed that among the three groups of rats, the left ventricular ejection fraction of the sham operation group was the highest, which was 7.7% and 4.6% higher than that of the operation group and the model group, respectively. The operation group had the highest left ventricular short axis shortening rate, and the left ventricle diastolic inner diameter is the longest. It can be seen that myocardial proteomics can accurately reflect the heart condition of rats. In addition, the length, diastolic velocity, and diastolic time of cardiomyocytes of the three groups of rats were different. Among them, the cardiomyocytes of the operation group had the longest time and the longest diastolic time, which were 37.1% and 8.5% higher than those of the sham operation group and the model group.
Judging from the current online teaching practice of higher physical education basic theory courses, there are many problems such as lagging theory, unclear models, confusing mechanisms, outdated methods, and lack of resources, resulting in the low interest of students. Basic theory courses are studied. The phenomenon of skipping class and being late is common, which seriously affects the improvement of the comprehensive quality of physical education students. Therefore, it has become an urgent problem for the majority of higher sports workers to develop learning resources for basic physical education courses and realize the innovation and application of the teaching mode of higher sports online courses. Compared with the traditional teaching method, the students’ physical education teaching performance is improved by about 30%, and their personality is fully developed. Linking teacher performance to changes in student performance parameters can effectively improve teacher motivation. This shows that under the background of intelligent sensor network, the physical education network course can effectively improve the teaching efficiency.
In order to solve the problem of the application of mobile information system in the transformation of ethnic physical education in colleges and universities in the 5G era, an analysis method based on the application of mobile information system in the transformation of ethnic physical education in colleges and universities in the 5G era is proposed. This method discusses the path of the transformation of ethnic physical education in colleges and universities through the analysis of the technological advantages in the 5G era. The experimental results show that: at present, under the influence of 5G technology, an important development path of ethnic physical education in colleges and universities is the modernization of education informatization. Through the construction and application of mobile information system, it can meet the increasing diversified sports needs of college students and promote the reform of college physical education. The mean value of competition video of film and television works related to classroom teaching content played before class is 4.576 standard deviation 0.673. Conclusion. On the basis of full use of 5G technology, teaching elements should be optimized, teaching resources should be enriched, and teaching mode should be reconstructed to promote the transformation of PHYSICAL education to digital information teaching.
