Physical education in middle school is very important for teenagers, so it is also crucial to understand the differences between PET (Physical Education Teaching) systems in middle schools at home and abroad. The frontier and hotspot of PET research in middle schools at home and abroad are examined in this paper using citation analysis, information visualization, and cluster analysis, as well as CiteSpace software. The findings show that PET method research in China is qualitative, whereas PET method research in middle schools around the world is quantitative evaluation and empirical research. Domestic research hotspots focus on classroom instructional design, whereas foreign countries focus on load identification theory's application in instructional design. Frontier research in the United States is dispersed and covers a wide range of topics, whereas research in other countries focuses on cognitive load theory. The classification time of this improved algorithm is reduced by 190.97 seconds when compared to the traditional KNN algorithm, and the total time is increased by more than 50%. According to the findings, nonsports or nonsports influencing factors should be given more consideration in the study of adolescent physical fitness decline in China.
中学体育教育对青少年非常重要，因此了解国内外中学体育教育（Physical Education Teaching，PET）系统的差异也至关重要。本文运用引文分析、信息可视化和聚类分析以及 CiteSpace 软件，探讨了国内外中学体育教育研究的前沿和热点。研究结果表明，中国的体育教学方法研究是定性的，而世界范围内中学的体育教学方法研究是定量评价和实证研究。国内研究热点集中在课堂教学设计上，而国外则侧重于负荷识别理论在教学设计中的应用。美国的前沿研究较为分散，涵盖了广泛的主题，而其他国家的研究则侧重于认知负荷理论。与传统的 KNN 算法相比，改进后的算法的分类时间减少了 190.97 秒，总时间增加了 50%以上。根据研究结果，中国在研究青少年体质下降时，应更多地考虑非体育或非体育影响因素。
