In the Internet + era, the dissemination of traditional sports culture of ethnic minorities is facing unprecedented challenges while ushering in great opportunities. This paper adopts PLS-based structural equation modeling method to construct a model of influencing elements of traditional sports culture dissemination of ethnic minorities, and builds an innovative path of traditional sports culture dissemination methods of ethnic minorities under the Internet+ era through the analysis of influencing factors. The process of minority traditional sports culture dissemination is divided into seven variable factors: individual audience, content ontology, dissemination subject, environment object, cognition, comprehension, and participation. In a series of research hypotheses, except for the research hypothesis of H2b (individual audience → comprehension) which was not valid (P=0.893>0.05), the rest of the research hypotheses were valid. All four factors - individual audience, environmental object, communication subject, and content ontology - positively influence comprehension and contribute positively. The three factors of environment, object, communication, and content ontology all have a positive influence on comprehension and play a positive contributing role. Finally, based on the conclusions, targeted and innovative communication paths are proposed to promote and optimize the communication effect of traditional minority sports culture.
