Analysis on the Latest Hotspot and Evolution about Abroad Soccer Fitness and Conditioning Training——Based on Visualization Research of Scientific Knowledge Map

Selecting the literature about soccer fitness and conditioning training from SCIE,SSCI and A&HCI as the research object,the author used the software Cite Space II to make visual analysis for 698 soccer fitness and conditioning training literature and their references published since 1985,in order to find out the hotspot and evolution about it.The results showed that the research of soccer fitness and conditioning training on abroad is primarily in developed countries such as America?and Europe;which is formed a complex discipline group dominated by the sports science and the evolution of research goes through these stages:exploration;expansion,deepness and integration etc.Research front is mainly concentrated in the overall training load;information gathering and evaluation methods;soccer injuries and physical rehabilitation;match performance and fitness demand;training design and training method.Many knowledge clusters and high-impact research become the driving force of the evolution for soccer fitness training theory and practice.
