Based on a large number of domestic and foreign literature, this paper sorts out the research perspectives and paradigms of specialized physical fitness training in football, and clarifies the research direction, changes in path, and development direction of the research. Research has shown that the current research on specialized physical fitness training in football mainly focuses on; The three different research perspectives and paradigms, starting from the understanding of physical fitness needs based on the characteristics of competition projects, analyzing exercise load based on physiological and biochemical indicators, and exploring energy supply modes based on energy consumption, reflect the evolutionary process of physical fitness research. Studying football physical fitness training from different perspectives requires a combination of interdisciplinary knowledge and targeted application in practical matches The comprehensive and scientific physical training work also provides reference for theoretical and practical research of football physical training.
