Physical fitness predicts technical-tactical and time-motion profile in simulated Judo and Brazilian Jiu-Jitsu matches

Abstract

BackgroundAmong combat sports, Judo and Brazilian Jiu-Jitsu (BJJ) present elevated physical fitness demands from the high-intensity intermittent efforts. However, information regarding how metabolic and neuromuscular physical fitness is associated with technical-tactical performance in Judo and BJJ fights is not available. This study aimed to relate indicators of physical fitness with combat performance variables in Judo and BJJ.MethodsThe sample consisted of Judo (n = 16) and BJJ (n = 24) male athletes. At the first meeting, the physical tests were applied and, in the second, simulated fights were performed for later notational analysis.ResultsThe main findings indicate: (i) high reproducibility of the proposed instrument and protocol used for notational analysis in a mobile device; (ii) differences in the technical-tactical and time-motion patterns between modalities; (iii) performance-related variables are different in Judo and BJJ; and (iv) regression models based on metabolic fitness variables may account for up to 53% of the variances in technical-tactical and/or time-motion variables in Judo and up to 31% in BJJ, whereas neuromuscular fitness models can reach values up to 44 and 73% of prediction in Judo and BJJ, respectively. When all components are combined, they can explain up to 90% of high intensity actions in Judo.DiscussionIn conclusion, performance prediction models in simulated combat indicate that anaerobic, aerobic and neuromuscular fitness variables contribute to explain time-motion variables associated with high intensity and technical-tactical variables in Judo and BJJ fights.

Technical-Tactical Behaviors Analysis of Male and Female Judo Cadets’ Combats

“…A potential limitation of behavior analysis is the consistency of the data achievement procedure, or the researcher's capability to reproduce the detected behavior once measurement is repeated (Coswig et al, 2018). Large variations in the combat moment, frequency and mean duration of actions measured during reliability analyses can affect inter-observer consistency (Coswig et al, 2018).…”

“…The observational-descriptive approach implemented in the current investigation may limit extrapolation of the results. Furthermore, cadet athletes likely produce dissimilar physical and physiological effects for a particular combat behavior than senior judo athletes (Coswig et al, 2018). During the present behavior analysis, weight divisions of female and male cadets demonstrated great temporal similarities, except for female half-heavyweight and heavyweight categories, in which tachi-waza (i.e., approach/gripping phases) was longer than half-lightweight division; however, without significant effects in the behavior frequencies, score or penalties for male and female younger judo athletes.…”

“…The performance in judo is associated with the ability of a male or female athlete to execute specific actions at the correct moment during each combat moment while quickly adapting to the constantly fluctuating combat environment to the next action (Brito et al, 2017). Technical-tactical behavior analysis have been well-described in judo, verifying match demands (Coswig et al, 2018), techniques and muscle group specific torque production (Lech et al, 2015). Specifically, during female and male judo adult's competition, technical-tactical actions of different technical-tactical behaviors and pause strategies are highly varied and the associations between these variables together describe a judo's system of attack or fighting style (López Díaz- de-Durana et al, 2018).…”

“…Particular behavior patterns that could determine different male and female cadet performance, considering maturational state and age effects (Fukuda, 2015), such as in senior, the approach trying to grip, gripping behaviors (kumi-kata), and scored attacks with different combinations (Coswig et al, 2018). Pinelopi Stavrinou et al (2017) indicated a high influence that several judo bouts have in perceived exertion and cardiovascular system, highlighting the anaerobic pathway as the main metabolic involvement during four simulated judo combats, with about 11 attacks on standing combat (tachi-waza) and one attack on groundwork combat (ne-waza) per combat.…”

Correlação de características antropométricas e qualidades físicas com desempenho técnico-tático em competição de judô: um estudo observacional

“…Neste sentido, é frequente a descrição de características morfofuncionais e metabólicas em relação a resultados competitivos (10,11) que, por vezes, se apresentam relacionados a temporalidade da luta (12)(13)(14) ou a análises técnico-táticas da luta (15)(16)(17). Neste contexto, destacam-se as análises dos elementos temporais e funcionais da luta, que permitem comparar a distribuição de frequência de ações na unidade de tempo de acordo com diferentes variáveis, dentre elas, o número de técnicas aplicadas, número de ações em relação a temporalidade da luta, qualidade dos ataques de pontuação (18).…”
