| Purpose: HIIT(high intensity interval training),also known as highintensity interval training,refers to the high-intensity training carried out in a short time and many times.The interval period is formed by active rest or noload rest between training intensity every two times.Some studies have shown that HIIT has a positive role in improving cardiopulmonary fitness,regulating glycolipid metabolism and reducing blood pressure.Therefore,researchers not only apply it to improve the exercise ability and physical quality of healthy people,but also try to use it as one of the exercise prescriptions for obese people,diabetic patients and many chronic diseases.Through the research of all aspects of HIIT,it is helpful to explore new ways of people's exercise,and provide practical guidance for the prevention,rehabilitation and treatment of patients with chronic diseases.Firstly,this paper analyzes the trend of domestic and international research on HIIT,and then analyzes the cooperation between authors and institutions,and the co citation of literature by using Cite Space visual tools.Then,it discusses the cooperation,research hotspot and evolution of foreign research by using the atlas,and then combs the relevant domestic literature Finally,combined with domestic and foreign research,it summarizes the trend of HIIT in recent years,the distribution of disciplines,the evolution and hot spots of foreign research,domestic research trends and hot spots.Through the understanding and grasp of the trend of publication,the distribution of disciplines and the research hotspot at home and abroad,it is conducive to the in-depth study of domestic HIIT theory and the application of practical results.Methods: literature,mathematical statistics and visual analysis.Results: 1)in recent years,the trend of domestic and foreign publications is increasing year by year.The rising node in foreign countries is 2014,while the domestic node is 2015.2)There are many interdisciplinary researches,among which sports science is the main subject,and other disciplines include physiology,medicine and molecular biology.According to the number of posts,foreign countries are ranked as: the United States,Australia,the United Kingdom,Canada,Brazil,etc.The domestic literature source journals are mainly sports,medicine and rehabilitation medicine.3)Through the analysis of knowledge map,it is found that the overseas research of HIIT is mainly divided into 7 clusters,#0 cluster is the summary and Application Research of HIIT research effect,#1 and #3 cluster is the physiological mechanism discussion of HIIT,#2 and #5 cluster is the research of HIIT and anti exercise fatigue,#4 cluster is the Research of HIIT application effect for chronic disease patients,and #6 cluster is the research of psychological adaptability of HIIT participants.4)The domestic research mainly includes four aspects: the application research of HIIT in the field of competitive sports special training,the application research in the field of exercise and rehabilitation,the comprehensive application research and the adaptive mechanism research.Conclusions: 1)the number of domestic and foreign research papers has increased significantly at the same time,indicating that the current research of HIIT has attracted the attention of scholars at home and abroad,guiding scholars to discuss the application effect of HIIT in different populations,so as to promote the development of HIIT in the field of public health.2)The research in interdisciplinary field and the cooperation and exploration of institutions promote the research to be deeper and broader,help to explore the application of HIIT in more chronic patient groups,and get the consensus of researchers,so as to promote public health.3)The evolution of foreign research,from the anti fatigue of HIIT to the physiological mechanism,because different researchers think that the application effect of HIIT for different groups of people can not reach an agreement,and then to the current research hotspot,mainly for the summary and application of HIIT and the psychological adaptation of HIIT.4)Future research trends: the number and achievements of related research continue to increase;the evaluation of sports effect gradually becomes multidimensional;the research depth is refined.Research hotspot: molecular mechanism of HIIT and psychological adaptation of HIIT. |
