In recent years,under the comprehensive influence of various factors,such as the guidance of national sports policies,the support of local governments,the enhancement of public fitness awareness,and the increase of sports consumption expenditure,domestic marathon events have witnessed a blowout growth trend,and the scale of runners has expanded rapidly.As an effective way for national fitness and a platform for displaying the charm of mass sports,marathon is developing vigorously,but there are also many problems such as low level of organization and management,inadequate security,homogenization of event products,incomplete cognition of runners,etc.,which have an adverse impact on the high-quality development of domestic marathon events.Based on this,from the perspective of marathon amateur runners,this study understands the relevant research results of marathon runners’ race participation,analyzes the influencing factors of marathon amateur runners’ race participation,builds a theoretical model of "the influence of marathon amateur runners’ race participation",identifies the negative causes of amateur runners’ race participation,and proposes the optimization countermeasures of marathon race system.Provide reference for the high quality development of domestic marathon.In this study,the runners’ motivation,experience,satisfaction and practical application of grounded theory were firstly reviewed to lay a theoretical foundation for the research.Secondly,the source of data was determined,and the online comments of marathon amateur runners were taken as the original data of the research.Word frequency statistics and high-frequency feature word analysis were carried out after screening and sorting of the original data,and then the three-level coding and theoretical saturation test were carried out according to the principles and methods of grounded theory,so as to build the theoretical model of "influencing factors of marathon amateur runners’ participation".Then,based on this theoretical model,the relationship between each main category and its subordinate initial category is deeply analyzed,the influencing mechanism of each factor is explored,the influencing causes of amateur runners’ race participation are summarized,and the targeted race optimization strategies are proposed according to the causes.Based on the research process and result analysis,the conclusions of this study are as follows:(1)Marathon amateur runners refer to those who participate in marathon at their own expense without formal systematic training due to their love for marathon,spiritual pursuit and the need of a certain purpose in their spare time.(2)The factors influencing the participation of amateur marathon runners include nine main categories: pre-race preparation,in-race organization,post-race guarantee,runners’ function,psychological level,competition achievement,geographical environment,infrastructure and cultural environment,which can be summarized into three aspects: competition organization,race environment and runners.(3)Among the influencing factors for the participation of amateur marathon runners,the race organization occupies a core position and is the main influencing factor.The runners themselves are endogenous factors,while the running environment is external influencing factor.(4)The main negative causes of marathon participation of amateur runners include "poor organizational process","inadequate security","unbalanced race cognition","frequent injuries of runners","great pressure on basic services" and "unmet demand for race tourism".(5)Aiming at the causes of the influence of marathon amateur runners’ participation in the event,it proposes the event system optimization strategy of "optimizing the organization system,building efficient management","strengthening the event supervision,implementing the security guarantee","focusing on information publicity,carrying out scientific training","improving the infrastructure,shaping the cultural environment","developing characteristic resources,and developing the event tourism". |
