Tibetan chess, a traditional Chinese ethnic sport, is a treasure of Tibetan culture. It takes various forms, adopts different playing methods, and involves a simple suite of equipment to interest people and impart wisdom. In order to study the positive impact that Tibetan chess exerts on students’ sports accomplishment, cognition, interest, intelligence, inheritance, and changes in their awareness of the protection of traditional sports in western Tibetan areas, this study uses correlation and single factor analysis to compare relevant indicators and dimensions. At the same time, it constructs regression models and path models for teaching experiments, investigations, and analyses. Research shows that the learning of Tibetan chess has obvious and significant influence on promoting students’ sports accomplishment in western Tibetan areas. Further research finds that the traditional sports of ethnic minorities, combined with the development of Tibetan chess and students’ sports accomplishment, establish the cognition of traditional sports culture, cultivate lifelong sports awareness, and allow students to enjoy the physical and mental education brought by ethnic cultures.
