Abstract

Against the backdrop of increasingly fierce global Olympic competition, coaches, especially “great coaches” with outstanding achievements and transnational coaching experience, are considered to be key factors in improving project breakthroughs and medal output. This paper uses Lang Ping and Bella Karolyi as representative cases to construct the “great coach effect” hypothesis and evaluate its causal impact on the number of Olympic medals based on the propensity score matching (PSM) method. The study first quantifies the performance differences before and after the coaching through Olympic medal data, and then constructs a treatment group and a control group to eliminate interference variables, and empirically verifies the significant positive effect of “great coaches” on medal growth. The study not only fills the quantitative gap of individual coach factors in sports policy evaluation, but also provides replicable methodological support for future countries in coach introduction and strategic layout.
