The present article briefly reviews the weight loss processes in combat sports. We aimed to discuss most relevant aspects of rapid (RWL) sports.This review was performed databases MedLine, Lilacs, PubMed and SciELO, organized into sub-topics: (1) prevalence, magnitude procedures, (2) psychological, physiological performance effects, (3) possible strategies avoid decreased (4) organizational such practices.There a high prevalence (50%) RWL, regardless specific discipline. Methods used are...
To identify the prevalence, magnitude, and methods of rapid weight loss among judo competitors.Athletes (607 males 215 females; age = 19.3 T 5.3 yr, 70 7.5 kg, height 170.6 9.8 cm) completed a previously validated questionnaire developed to evaluate in athletes, which provides score. The higher score obtained, more aggressive behaviors. Data were analyzed using descriptive statistics frequency analyses. Mean scores obtained used compare specific groups athletes using, when appropriate,...
The aim of this study was to investigate the methods adopted reduce body mass (BM) in competitive athletes from grappling (judo, jujitsu) and striking (karate tae kwon do) combat sports state Minas Gerais, Brazil. An exploratory methodology employed through descriptive research, using a standardized questionnaire with objective questions self-administered 580 (25.0 ± 3.7 yr, 74.5 9.7 kg, 16.4% 5.1% fat). Regardless sport, 60% reported method rapid weight loss (RWL) increased energy...
The understanding of time-motion and physiological responses to judo combat is important training organization. This review was based on search results using the following terms: “judo competition”, physiology”, randori”, analysis”, combat”, match” biochemestry”. effort-pause ratio during combats between 2:1 3:1, with 20s 30s effort periods 10s pauses. Thus, rely all three metabolisms, anaerobic alactic sytem being reponsible by short duration powerful actions technique applications, lactic...
Abstract Objective Our objective was to explore the training-related knowledge, beliefs, and practices of athletes influence lockdowns in response coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome 2 (SARS-CoV-2). Methods Athletes ( n = 12,526, comprising 13% world class, 21% international, 36% national, 24% state, 6% recreational) completed an online survey that available from 17 May 5 July 2020 explored their training behaviors (training...
The aim of the present study was to determine time structure and physiological responses during Songahm Taekwondo (TKD) competition compare these variables between winner non-winner athletes. Fourteen men subjects were analyzed. Blood lactate concentration (LA) heart rate (HR) determined before after match. match filmed for determination number techniques used, duration effort rest periods (RPs), interval high-intensity movements (HM). Post-match LA 7.5 +/- 3.8 mmol x L(-1), HR 183 9 b.x...
The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. following groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 353); Junior (19 349) and Senior (>20 587). included: Total Combat Time, Standing Displacement Without Contact, Gripping Groundwork Time Pause Time. Analysis variance (ANOVA) one-way the Tukey test, as well Kruskal-Wallis test Mann-Whitney (for non-parametric data), conducted,...
In this study, we investigated the effects of rapid weight loss followed by a 4-h recovery on judo-related performance. Seven weight-cycler athletes were assigned to group (5% body reduction self-selected regime) and seven non-weight-cyclers control (no reduction). Body composition, performance, glucose, lactate assessed before after (5-7 days apart; kept stable). The had 4 h re-feed rehydrate weigh-in. Food intake was recorded during period Performance evaluated through specific judo...
The purpose of this study was to determine the relationship between attack time (AT) and skipping (ST) during 2007 Taekwondo World Championship 2008 Beijing Olympic Games. A total 22 matches (65 rounds, 13 semifinals, 8 finals) from 23 (63 rounds with 16 athletes each 1 quarterfinal round) Games, both in male category, were assessed using time-motion analysis. AT considered as which athlete attacked or tried attack, whereas ST without attempting attack. ratio ∼ 1:7 based on data pooled 2...
This study investigated the relationship between punching impact and selected strength power variables in 15 amateur boxers from Brazilian National Team (9 men 6 women). Punching was assessed following conditions: 3 jabs starting standardized position, crosses a self-selected position. For tests, force platform (1.02 × 0.76 m) covered by body shield mounted on wall at height of 1 m, perpendicular to floor. The were vertical jump (in squat countermovement jump), mean propulsive squat, bench...
To estimate the contribution of 3 energy systems to simulated judo matches.Twelve athletes (18 ± 1 y, 175.1 5.3 cm, 74.3 10.5 kg, 11.7% 1.5% body fat, 8 2 y practice) performed 5 combats with different durations (1, 2, 3, 4, and min), against same opponent, on days blinded duration. The estimated contributions for oxidative, glycolytic, ATP-PCr were calculated based oxygen uptake (V̇O2) during activity, Delta lactate, fast phase excess V ̇ O2, respectively. Analysis mixed models repeated...
The present study aims at investigating the physiological response and technical-tactical parameters in Brazilian jiu-jitsu competition.The included 35 male athletes (adult category, body mass: 80.2 ± 13.0 kg), graded from white to brown belt, during combats fought regional level. Twenty-two fights were analyzed terms of technique time structure. Blood glucose, lactate maximal isometric grip strength determined before after fights. rate perceived exertion was also assessed fight, using 6-20...
