Visual Analysis Of The Frontiers And Hot Spots In The Field Of Physical Activity Of Young People At Home And Abroad

Teenagers are the hope of a nation in the future.The results of domestic research on the physical health of teenagers show that the trend of continuous decline of physical health of teenagers has not been fundamentally contained.The obesity rate continues to rise,the age of myopia is declining at a younger age,and the problem of insufficient physical activity is prominent.Based on citation space software and related knowledge graph theory,the literatures in the field Of physical activity Of domestic and foreign adolescents from 2010 to 2020 included in the core collection Of Web Of Science and Chinese Social Science Index Database which are required to be included at a higher level were collected and processed by co-word analysis,cooperative network analysis and other methods.And with the help of software,draw the outline of domestic and foreign youth physical activity field visualization map.In the research frontier,Kleinberg algorithm is used to detect salient words,and the research frontier is determined and analyzed after analysis and extraction.Cite Space is used to conduct objective qualitative and quantitative research on the current field to determine the differences between domestic and foreign research hot spots in the field of adolescent physical activity.The findings are as follows :(1)Sedent behavior,accelerometer,epidemiology and basic motor skills are the main topics of physical activity among Chinese adolescents.The hot topics of physical activity among adolescents abroad are Overweight,Walking,Exercise,Environment,Sedentary Behavior,accelerometers,and so on.(2)The theme of the frontier of physical activity of teenagers in China focuses on three directions: wearable devices,national fitness and the United States;The frontiers of foreign teenagers’ Physical activities focus on Motivation,Physical Education,Play and other aspects,which are significantly different from each other.(3)A comparative analysis of domestic and foreign studies on physical activity of adolescents shows that the number of papers published on physical activity of adolescents at home and abroad is increasing,but the increase of foreign studies on physical activity is more obvious;(4)Consensus has been reached on multi-sectoral cooperation research,but cooperation abroad is closer;(5)There are differences in the hot topics of adolescent physical activity research at home and abroad,and the hot topics of foreign physical activity research are more than domestic hot topics.(6)The evolution stage of research topics on adolescent physical activity at home and abroad is roughly the same,but foreign research topics are more subtle.Finally,the following enlightenment can be obtained in the field of adolescent physical activity research in China :(1)pay attention to the cross integration of disciplinary research;(2)Pay attention to the local reference of foreign research frontiers and hot spots;(3)Actively explore the research paradigm of adolescent physical activity in China.This paper hope for adolescent physical activity related research in the field of power,help the relevant scientific research workers quickly grasp the development trend in this field,analyzes the hotspot and frontier in the field of mining,in order to solve the physical health of students in China to promote provide reference and the problems faced in the field of ideas,in order to provide subtle enlightenment for the future related research.
