The Work Endurance Recovery Method for Quantifying Training Loads in Judo.

PURPOSE: To adapt the work endurance recovery (WER) method based on randori maximal time to exhaustion (RMTE) for combat situations in judo.

METHODS: Eleven international-standard judo athletes (7 men and 4 women; mean age 20.73 ± 2.49 y, height 1.72 ± 0.11 m, body mass 67.36 ± 10.67 kg) were recruited to take part in the study. All participants performed a maximal incremental test (MIT), a Wingate test (WIN), a Special Judo Fitness Test (SJFT), and 2 RMTE tests. They then took part in a session at an international training camp in Barcelona, Spain, in which 4 methods of load quantification were implemented: the WER method, the Stagno method, the Lucia method, and the session rating of perceived exertion (RPEsession).

RESULTS: RMTE demonstrated a very high test-retest reliability (intraclass correlation coefficient = .91), and correlations of the performance tests ranged from moderate to high: RMTE and MIT (r = .66), RMTE and WIN variables (r = .38-.53), RMTE and SJFT variables (r = .74-.77). The correlation between the WER method, which considers time to exhaustion, and the other systems for quantifying training load was high: WER and RPEsession (r = .87), WER and Stagno (r = .77), WER and Lucia (r = .73). A comparative repeated-measures analysis of variance of the normalized values of the quantification did not yield statistically significant differences.

CONCLUSIONS: The WER method using RMTE is highly adaptable to quantify randori judo sessions and enables one to plan a priori individualized training loads.
