- Abstract
Purpose: The aim of this study was to investigate the time-motion of the matches and patterns of salivary biomarkers during different championship judo phases. For this, eight male judo athletes from all weight divisions (16 ± 6 years of practice) were studied during an official championship. Methods: The combats were recorded and a time-motion analysis was made, assessing total time by combat and time per block of action (approach time, gripping time, time of attack/defense, groundwork combat time, and pause time). Saliva samples were collected for the measurement of cortisol, total protein, and osmolality levels. Results: There were differences between championship phases with post-match 3 (11.4 ± 4 ng/mL) and post-match 2 (10.3 ± 6 ng/mL) presenting higher cortisol values than pre-match 1 (5.5 ± 1.8 ng/mL) ( p < 0.05 for both comparisons). In addition, post-match 3 (11.4 ± 4 ng/mL) was higher than post-match 1 (6.5 ± 3 ng/mL) ( p < 0.05). In the time-motion analysis, there were no differences ( p > 0.05) between different championship phases. The only difference observed was a higher number of ippon between the matches, with higher values for the first compared to the second match ( p < 0.05). Conclusion: It is suggested that judo matches present a pattern that does not change in the distinct phases of the competition. Cortisol may be considered as a marker of intensity of effort during judo matches.
