Judo technical-tactical dynamics: analysis of attack system effectiveness in high-level athletes

This study aimed to determine which attack systems resulted in higher effectiveness in judo combats. We examined 5847 attacks from 152 high-level international male medallist athletes. Both successful (score) and unsuccessful attacks (no-score) were comprehensively analysed including six variables per action: attacker/defender approach, grip, stance, final displacement and direction of attack. Logistic regression, decision tree analyses and odds ratio (OR) were calculated to determine the probability of success for a given attack system. The main results indicated that i) gripping the dorsal region was decisive for an effective attack, ii) Right-Dorsal & Left-Dorsal grip configuration was the most efficient (P
