Performance measurement in Judo: main KPIs, cluster categorization and causal relationships

Performance measurement in Judo usually focuses on some KPIs whose values indicate the final performance of the athlete. This paper deals with firstly identifying which these main Key Performance Indicators (KPIs) in Judo are. Once this is done, the KPIs are classified into four different clusters: Physical training, Specific training, Psychology and Lifestyle. Then, it moves into analyzing possible quantitative techniques to identify cause-effect relationships between KPIs in order to link not only the impact of the Judo KPIs with the achievement of the judoka’s strategic objectives but also to identify both the relative and the global importance of each of these KPIs. Finally, it points out the Analytic Network Technique as the one that could be ideally applied in this context and offers future research actions.
