Physical literacy is a new concept proposed in response to the global health crisis caused by the sedentary lifestyle in today's society,which emphasizes the people-oriented concept,pays attention to the emotional experience of individuals participating in physical activities,and integrates physical activities into the life of human beings in the whole life cycle,and it has attracted the attention of sports and other research fields. With the introduction of the new concept,10 related concepts such as sports literacy,sports core literacy,sports discipline literacy and fitness literacy have appeared in China,causing the phenomenon of conceptual confusion and controversy,and affecting the understanding and use of concepts by researchers and practical operators. By sorting out the background and connotation of each concept,it is found that the connotation of physical literacy is different from that of relevant concepts in China,some concepts are included in physical literacy,and conceptual integration can be carried out to reduce the phenomenon of mixing application in academia circles and practical application fields. The analysis of the connotations of physical literacy and other related concepts will help to carry out relevant research on physical literacy to play its important role in sports reform,the building of a leading sporting nation and the building of a healthy China in China,and also help other concepts to play their respective roles in the sports discipline,curriculum reform and national fitness in China.
