Abstract

Purpose: The present study aims at investigating the physiological response and technical-tactical parameters in Brazilian jiu-jitsu competition.

Methods: The study included 35 male Brazilian jiu-jitsu athletes (adult category, body mass: 80.2 13.0 kg), graded from white to brown belt, during combats fought at regional level. Twenty-two fights were analyzed in terms of technique and time structure. Blood glucose, lactate and maximal isometric grip strength were determined before and after the fights. The rate of perceived exertion was also assessed after the fight, using the 6-20 Borg rating. The fights were recorded and the following variables were determined: the exertion/pause ratio and subjective intensity of actions, categorized between low and high intensity.

Results: The results indicated that during Brazilian jiu-jitsu fights, the glycolytic pathway is only moderately activated (lactate before: 4.4 (4.0 4.6) mmol/L, after: 10.1 (8.0 11.3) mmol/L; glucose before: 112.4 22.3 mg/dL, after: 130.5 31.0 mg/dL). The exertion during the fight resulted in significant reductions in handgrip strength (right hand grip before: 45.9 10.3 kgf, after: 40.1 9.5 kgf; left hand grip before: 44.2 11.1 kgf, after: 37.0 10.2 kgf). The athletes rated the fight as hard: 15 (13 15). Effort/pause ratio was 6:1, while high-intensity actions lasted approximately 4 s, resulting in a low/high intensity? ratio of 8:1.

Conclusion: It is recommended that coaches direct the training loads to simulate the energy demand imposed by the competitive matches, activating moderately the glycolytic pathway. Moreover, the time structure of combats can be used to prescribe both physical and technical-tactical training.
