Abstract

Biathlon is a unique winter sport that combines precision rifle marksmanship with the endurance demands of cross-country skiing. We develop a Bayesian hierarchical model to predict and understand shooting performance using data from the 2021/22 Women’s World Cup season. The model captures athlete-specific, position-specific, race-type, and stage-dependent effects, providing a comprehensive view of shooting accuracy variability. By incorporating dynamic components, we reveal how performance evolves over the season, with model validation showing strong predictive ability at both overall and individual levels. Our findings highlight substantial athlete-specific differences and underscore the value of personalised performance analysis for optimising coaching strategies. This work demonstrates the potential of advanced Bayesian modelling in sports analytics, paving the way for future research in biathlon and similar sports requiring the integration of technical and endurance skills.
