Abstract

Judo has as main characteristic the intermittence due to the sequences of effort and pause that have varied durations according to the actions conducted by the athletes. The way the athlete distributes the effort over time is called pacing. It is recognized that this phenomenon has great impact on competitive performance. Although several actions performed by the athletes during a fight have already been analyzed, pacing has not been investigated in this modality. In this way, the objective of this study is to analyze pacing in judo, comparing the temporal structure and the technical and tactical actions along the different moments of the match, in competitions of the international ranking system with different degrees of importance. For this, approximately 2,260 fights of the seven competition levels of the international ranking system will be part of the research. The fights will be analyzed using a video analysis program, through which the performance indicators will be determined. The frequency of each movement time indicator will be collected for each fight and expressed per second of combat and later expressed by each minute of combat to obtain pacing indicators. The different competitions will be compared in relation to these aspects, focusing on the frequency of the indicators per minute, using analysis of variance or non-parametric test for comparisons of multiple conditions.
