新世纪以来的中国体育电影，不管是作为北京“双奥之城”的见证者，诞生出大量传递奥林匹克时代精神的优秀主旋律影片，还是作为中国电影类型片的突破者，努力在体育强国梦的宏观建构和个体生命体验的微观表达之间进行着积极探索，都展现出极大的研究价值和时代意义。同时，教练角色的叙事功能表现也呈现出多层次、多元化、多角度的特征。既有对结构主义叙事学传统理论的应用，也有结合体育题材专业叙事语境进行的突破与创新。

论文在绪论部分梳理了以往相关的研究成果，厘清了中国体育题材电影的叙事变迁，并进行教练角色和研究时期的界定。

第一章“教练角色在主题表达中的功能”，抽取教练作为职业人的具体表现进行划分，以“奉献式的地方队教练”“权威式的国家队教练”“颠覆式的私人职业教练”三个类型，归纳出教练角色在宏观性国家时代背景和微观性个体成长主题的叙事承载。

第二章“教练角色在人物关系构建中的功能”，结合普罗普人物原型理论进行划分，以“运动员精神追求的引领者”“运动员人格完善的激励者”“运动员自我超越的助推者”，分析出教练和运动员之间“师徒关系”“助手关系”“对手关系”的构建方式。

第三章“教练角色在推动情节发展中的功能”，以“驱动故事发展”“串联故事情节”“扩充故事维度”的角度进行阐释，并结合传统三幕式英雄之旅的故事模型和体育题材电影的专业语境，将其延伸为“擎动成长的赛道”“从突破躯体极限到领悟竞技真谛”“丰富成长的内涵”具体故事内容。

第四章“教练角色在矛盾冲突构建中的功能”，结合格雷马斯的行动元模式和符号矩阵理论，以图文和表格的形式，将教练角色在表层结构下如何以集体荣誉为目标构建团队冲突，在深层结构下如何以实现运动员价值为主旨完成意义表达，进行由表及里的深入剖析。

综上所述，本文以教练角色的叙事功能性为切入点，梳理出教练角色在横跨整个北京双奥运周期的时代背景下，完成的多层次叙事主题表达；总结出教练角色在以运动员为核心主角的叙事语境下，围绕构建人物关系、推动情节发展、构建矛盾冲突方面表现出的具体功能性作用。以期通过本文引起中国电影创作者和从业者对体育题材电影叙事内容的挖掘和角色塑造策略的思考。

Since the turn of the century, there has been a significant research focus on the narrative function of coach roles in Chinese sports-themed movies. These films, whether as witnesses of the "Double Olympics City" of Beijing, or as pioneers of Chinese film genres, have explored the macro and micro expressions of the dream of building a sports powerhouse in China with great research value and contemporary significance. Meanwhile, the narrative function of coach roles have exhibited multi-level, diverse, and multi-perspective. These functions involve both the combination and application of traditional theory in structuralist narrative studies and breakthroughs and innovations combined with professional sports themes.

In the introduction part, the article sorts out the relevant research results in the past, clarifies the narrative changes of Chinese sports-themed films, and defines the role of coaches and the research period.

Chapter One, "The Function of Coach Roles in Theme Expression," first distinguishes coaches' specific professional roles as "dedicated local team coaches," "authoritative national team coaches," and "subversive private coaches," and summarizes the narrative of the role of coach in the macro national era background and the micro individual growth theme.

Chapter Two, "The Function of Coach Roles in Character Relationship Construction," distinguishes coaches' roles based on the theoretical basis of the Propping character prototype as "the leader of athletes' spiritual pursuits," "the motivator of athletes' personality perfection," and "the promoter of athletes' self-transcendence." The article analyzes the process of building character relationships between coaches and athletes as "master-disciple relationship," "assistant relationship," and "opponent relationship."

Chapter Three, "The Function of Coach Roles in Plot Development," interprets three specific types of functions, "driving story development," "linking story plots," and "expanding story dimensions," and extends them to three specific story contents: "the race track that drives growth," "from breaking physical limits to understanding the essence of competition," and "enriching the connotation of growth."

Chapter Four, "The Function of Coach Roles in Conflict Construction," uses Greimas actantial model and symbolic matrix theory to conduct an in-depth analysis of how coach roles construct team conflicts with collective honor as the goal on the surface structure and complete the expression of the meaning of achieving athletes' values on the deep structure. This is done through tables and graphics that delve into the surface and depth of coach roles' functions in conflict construction.

To sum up, this article takes the coach as a functional narrative role as the starting point, and sorts out the diversified theme expression of the coach role that spans the entire Beijing Double Olympic Cycle in Chinese sports-themed films since the new century; in the narrative context with athletes as the core protagonists, the functional role of coach roles in constructing character relationships, advancing the plot, and creating conflict is summarized. In order to arouse the thinking of film creators and practitioners on the narrative content mining and role shaping strategies of Chinese sports-themed films.
