Leitura para as férias

Comecei hoje, mas já gostei, pois é o primeiro livro em português que vejo desmitificar os samurais, os quais nem por isso deixam de ser menos interessantes do ponto de vista histórico e como referencial para os praticantes de artes marciais ou lutas.

Department of Physiology, Trinity College, Dublin 2, Ireland, jordanm1@tcd.ie.

Abstract
Limited research documents if new and existing interactive computer gaming "exergaming" increase energy expenditure and cardio-respiratory costs comparable to common exercise modalities. To address this, healthy male volunteers (n = 15) completed six by 12-min test elements: PlayStation2 (PS2(hand)), Nintendo Wii boxing, walk at 5.6 km h(-1), cycle at 120 W, playing an adapted lower limb controlled PS2 (PS2(limb)) and run at 9.6 km h(-1). In addition, they played PS2(limb) for 30 min and performed an incremental treadmill test to exhaustion. Data were analysed using repeated measures ANOVA with post hoc Tukey tests, P < 0.05 inferred significance. PS2(limb) increased energy expenditure (EE) and post-exercise blood lactate (BLa) significantly higher (P < 0.001) than PS2(hand), Wii gaming or walking at 5.6 km h(-1) (EE: 30.3 ± 4.9 vs. 4.7 ± 1.1, 22.0 ± 6.1 and 17.9 ± 1.9 kJ h(-1) kg(-1); BLa: 2.4 ± 1.5 vs. 1.0 ± 0.3, 1.8 ± 0.8 and 0.9 ± 0.2 mmol L(-1)), playing the PS2(limb) raised mean EE over six times greater than PS2(hand). Mean fat and carbohydrate oxidation rates during the 9- to 12-min period playing the PS2(limb) were five and ten times greater than PS2(hand) (0.25 ± 0.10 vs. 0.05 ± 0.10, 1.69 ± 0.52 vs. 0.15 ± 0.14 g min(-1), respectively). PS2(limb) met ACSM guidelines for cardiovascular fitness; however, current Wii technology failed. In conclusion, gaming interactive technology must be adapted or designed to include the lower limbs in order to provide a significant exercise stimulus.

Abstract
In this study, we determined the specificity of a low frequency taekwondo training programme on physical fitness levels in adolescent females who receive limited physical education instruction (i.e. 2 days per week). Major components of physical fitness assessed were: skeletal muscle fitness (hand grip strength, bent arm hang, standing long jump, and isokinetic strength), flexibility (sit-and-reach test), speed and agility (10 × 5-m shuttle run), and cardiovascular fitness (VO2max and 20-m shuttle run). Changes in body composition were also assessed (dual X-ray absorptiometry, DXA). Participants were divided into two groups, a taekwondo training group (n = 21), which trained 50 min a day, 2 days per week for 12 weeks, and a control group (n = 10). Taekwondo training improved isokinetic strength, standing long jump, and sit-and-reach performance. Body fat mass and percent body fat were reduced. No changes in grip strength, bent arm hang time, speed and agility, or cardiorespiratory fitness were observed. Results indicate that low frequency taekwondo training in adolescent females produces beneficial changes in skeletal muscle fitness, flexibility, and body composition in a relatively short period of time. Consequently, this specific type of training can be useful to female adolescents in structured school environments where physical education classes are limited and there is little free time for physical activity.

Department of Physical Education and Sport Science, Democritus University of Thrace, 69100, Komotini, Greece.

Abstract
The aim of this study was to determine the effects of a simulated one-day Greco-Roman wrestling tournament on selected performance and inflammatory status indices. Twelve competitive wrestlers (22.1 ± 1.3 years) completed five matches according to the official Olympic wrestling tournament regulations following a ~6% weight loss. Performance measurements, muscle damage assessment, and blood sampling were performed before and following each match. Performance and inflammatory markers were not affected by weight loss. Mean wrestling heart rate reached ~85% of maximal and lactate concentration exceeded 17 mM. Fatigue rating demonstrated a progressive rise (P < 0.05) throughout the tournament, peaking in match 4. Performance demonstrated a progressive deterioration (P < 0.05) throughout the tournament, especially in the last two matches (P < 0.05), with upper-body measures exhibiting a greater decline (P < 0.05) and remaining below baseline (P < 0.05) until the end of the tournament. Muscle damage markers increased during the course of the tournament with upper limbs affected more. Creatine kinase activity, CRP levels, IL-6 concentration, and leukocyte counts increased (P < 0.05) progressively throughout the tournament, peaking in the last two matches. Cortisol, epinephrine and norepinephrine increased (P < 0.05) after each match, but testosterone declined (P < 0.05) progressively, reaching a nadir before the last match. This inflammatory response was accompanied by a marked increase (p < 0.05) in lipid peroxidation, protein oxidation, and antioxidant status markers indicating the development of oxidative stress. These results suggest that a one-day wrestling tournament may induce significant physiological demands on wrestlers that may adversely affect their performance and inflammatory status especially during the later stages of the tournament.

Eder Jofre ganha Troféu Adhemar Ferreira da Silva (Fonte: COB)

São Paulo - Em 2010, o esporte brasileiro comemorou os 50 anos da conquista do maior pugilista da história nacional: Éder Jofre. Em 1960, aos 24 anos, ele conquistou o título mundial dos galos, ao nocautear o mexicano Eloy Sánchez, nos Estados Unidos, por nocaute, no 6º rounde. Em homenagem ao boxeador, revelado na antiga academia do São Paulo FC e que conservou o cinturão da Associação Mundial de Boxe (AMB) por cinco anos, o Comitê Olímpico Brasileiro concedeu o Troféu Adhemar Ferreira da Silva, instituído em 2001 e entregue, tradicionalmente, na cerimônia do Prêmio Brasil Olímpico. Este ano o evento está marcado para o próximo dia 20, no Rio de Janeiro, no Teatro do MAM.
O Troféu Adhemar Ferreira da Silva premia atletas que aliam eficiência técnica, esportividade, companheirismo, sentido de coletividade e respeito ao próximo. "Agradeço o reconhecimento que o COB, fico emocionado por ter minhas conquistas lembradas até hoje", declarou Eder, hoje com 74 anos. "O boxe representa tudo para mim e a ele devo tudo que ganhei na vida. Espero que minha conduta e minhas conquistas continuem servindo como exemplos para a juventude, a quem eu sempre aconselho que se dedique integralmente ao esporte", afirmou.
Em 1973, Eder conquistou seu segundo título mundial, agora na categoria pena, e manteve a posição por três anos, até aposentar-se, aos 40. Possui um cartel invejável de 72 vitórias na carreira, sendo 50 por nocautes, com quatro empates e apenas duas derrotas. No início da década de 1990, o Eder Jofre foi incluído na seleta lista de estrelas do Hall da Fama do boxe.
O Troféu
O Troféu Adhemar Ferreira da Silva foi criado pelo COB em 2001, como forma de homenagear atletas e ex-atletas que representem os valores éticos, esportivos e morais que marcaram a trajetória de Adhemar, um exemplo de eficiência técnica, esportividade, companheirismo, sentido de coletividade e respeito ao próximo, entre outros.
Adhemar, paulistano da Casa Verde, morto em 2001 aos 73 anos, foi bicampeão olímpico do salto triplo, em Helsinque 1952 e Melbourne 1956. Ainda nos anos 1950, estabeleceu cinco vezes o recorde mundial da prova e conquistou o tricampeonato pan-americano.

Abstract
Fry, AC, Schilling, BK, and Kraemer, WJ. Relationships between competitive wrestling success and neuroendocrine responses J Strength Cond Res 24(X): 000-000, 2010-Previous research on wrestling suggests winning wrestlers will have a greater increase in testosterone (Tes) than losing wrestlers, although the physiological mechanism is unknown. To determine the role of the sympathetic nervous system in this phenomenon, 12 male wrestlers from an National Collegiate Athletic Association Division I program wrestled 5 matches over a 2-day period. Serum samples were collected pre (Pre) and immediately postmatch (Post) for the determination of Tes, cortisol (Cort), Tes/Cort, and epinephrine (Epi). The subjects had a combined record of 34 wins, 31 losses, and 4 ties. Testosterone increased (p < 0.05) for both winners and losers, but the increase was greater for winners (X ± SE; nmol·L; winners, pre = 16.4 ± 1.2, post = 23.2 ± 1.5; losers, pre = 14.8 ± 1.0, post = 19.4 ± 1.2). Cortisol and Epi increased similarly for both winners and losers, whereas the Tes/Cort ratio was unaltered at any time. Relative changes in the Epi response (%Δ) for losers were correlated to %ΔTes (r = 0.91), whereas winners did not exhibit similar relationships (r = 0.09). These data suggest that winning wrestlers may use a different regulatory mechanism for their acute Tes responses than losers who appear to depend on sympathetic regulation. Additionally, these data from humans support the biosocial theory of status and the challenge hypothesis developed for competing males in other species.

Abstract
The purpose of this study was to identify the characteristics of Olympic medal winners (gold, silver, bronze) who competed in the 2008 Beijing Olympic Games and compare these characteristics to those who competed but did not earn medals. We have also descriptively analysed the 2008 data in comparison to the 2004 data (Kazemi et al., 2009), and 2000 data (Kazemi et al., 2006) and summarized changes that were identified. This study as well as the last two studies did not find any statistically significant differences between winners and non-winners with regards to average age, weight, height and BMI. There are, however, some trends that were observed. Female winners were slightly younger, shorter, with greater BMI's versus non-winners. There was a significant decrease in frequency of warnings from 2004 to 2008. Unlike 2004, the 2008 Olympic Taekwondo competitors used more defensive kicks to score. These suggest a shift from aggressive tactics to score to a more conservative one.

Unité de Formation en Sciences et Techniques des Activités Physiques et Sportives, Orleans, France.

Abstract
The aim of this investigation was to assess the effects of 6 wk of eicosapentanoic acid (EPA) and docosahexanoic acid (DHA) supplementation on resting and exercise-induced lipid peroxidation and antioxidant status in judoists. Subjects were randomly assigned to receive a placebo or a capsule of polyunsaturated fatty acids (PUFAs; 600 mg EPA and 400 mg DHA). Blood samples were collected in preexercise and postexercise conditions (judo-training session), both before and after the supplementation period. The following parameters were analyzed: α-tocopherol, retinol, lag phase , maximum rate of oxidation (Rmax) during the propagating chain reaction, maximum amount of conjugated dienes (CDmax) accumulated after the propagation phase, nitric oxide (NO) and malondyaldehide (MDA) concentrations, salivary glutathione peroxidase activity, and the lipid profile. Dietary data were collected using a 7-day dietary record. A significant interaction effect between supplementation and time (p < .01) on triglycerides was noted, with values significantly lower in the n-3 long-chain-PUFA (LCPUFA) group after supplementation than in the placebo group. Significant interaction effects between supplementation and time on resting MDA concentrations and Rmax were found (p = .03 and p = .04, respectively), with elevated values in the n-3 LCPUFA group after supplementation and no change in the placebo group's levels. The authors observed a significantly greater NO and oxidative-stress increase with exercise (MDA, Rmax, CDmax, and NO) in the n-3 LCPUFA group than with placebo. No main or interaction effects were found for retinol and α-tocopherol. These results indicate that supplementation with n-3 LCPUFAs significantly increased oxidative stress at rest and after a judo-training session.

The social-psychological outcomes of martial arts practise among youth: A review
Jikkemien Vertonghen 􀀍 and Marc Theeboom
Vrije Universiteit Brussel, Belgium
Abstract

Martial arts involvement among the youth has been described in controversial terms. Studies regarding the effects of martial arts practise on youth show contrasting images. While some refer to enhanced personal and social opportunities for those that participate, others warn against increased levels of aggressiveness and antisocial behavior among its participants. The aim of the present review is to provide, firstly, an overview of the major findings of studies concerning the social-psychological outcomes of martial arts practise. Secondly, the limitations of those studies are discussed. From more than 350 papers, collected during a two-year lasting literature study, 27 papers met all criteria to be included in this study. This review revealed that even though a considerable amount of research on socialpsychological outcomes of martial arts practise has been conducted over the years, to date, it has not brought clarity in the existing duality regarding the possible effects of martial arts involvement. It is proposed that a better understanding can be provided if specific influential factors are taken into account in future research (i.e., participants’ characteristics, type of guidance, social context and structural qualities of the sport).

Sport, University of São Paulo, Brazil

Abstract
In judo, the two contestants get close to each other, perform their grasps, move on the mat and attack. The approaches and kumi-kata (grip technique) give way to specific behaviors between the two contestants. The briefness and the capacity of simultaneous actions, the multiple interactions and the result at stake result in a complex system that is most of the time clarified by the coach to the contestant. A computerized observation may help to highlight some actions associated to success from that complex system. The winners of 35 contests were analyzed (9 beginners, 16 intermediate levels, and 10 experts) through their behaviors (approaches and kumi-kata) and positions. The results enable experts to assume lengths (15.8±9.5s) and amount (9±6) of the combat phases (lapse of time between beginning and stop, announced by the referee) similar to the other two groups. Beginners approach each other with much care and precision, mainly holding their opponents with both hands for the projection. The percentage of total time spent by beginners and experts grabbing the opponent’s judogi with both hands, attack and throw was 86% and 24%, respectively, indicating a much lower time spent between grip contact and technique application in experts compared to beginners.

Boxing Training for Patients With Parkinson Disease: A Case Series.
Combs SA, Diehl MD, Staples WH, Conn L, Davis K, Lewis N, Schaneman K.
Krannert School of Physical Therapy, University of Indianapolis, 1400 E Hanna Ave, Indianapolis, IN 46227 (USA).
Abstract
BACKGROUND AND PURPOSE: A nontraditional form of exercise recently applied for patients with Parkinson disease (PD) is boxing training. The primary purpose of this case series is to describe the effects of disease severity and duration of boxing training (short term and long term) on changes in balance, mobility, and quality of life for patients with mild or moderate to severe PD. The feasibility and safety of the boxing training program also were assessed.
CASE DESCRIPTION: Six patients with idiopathic PD attended 24 to 36 boxing training sessions for 12 weeks, with the option of continuing the training for an additional 24 weeks (a seventh patient attended sessions for only 4 weeks). The 90-minute sessions included boxing drills and traditional stretching, strengthening, and endurance exercises.
OUTCOMES: were tested at the baseline and after 12, 24, and 36 weeks of boxing sessions (12-, 24-, and 36-week tests). The outcome measures were the Functional Reach Test, Berg Balance Scale, Activities-specific Balance Confidence Scale, Timed "Up & Go" Test, Six-Minute Walk Test, gait speed, cadence, stride length, step width, activities of daily living and motor examination subscales of the Unified Parkinson Disease Rating Scale, and Parkinson Disease Quality of Life Scale. Outcomes Six patients completed all phases of the case series, showed improvements on at least 5 of the 12 outcome measures over the baseline at the 12-week test, and showed continued improvements at the 24- and 36-week tests. Patients with mild PD typically showed improvements earlier than those with moderate to severe PD.
DISCUSSION: Despite the progressive nature of PD, the patients in this case series showed short-term and long-term improvements in balance, gait, activities of daily living, and quality of life after the boxing training program. A longer duration of training was necessary for patients with moderate to severe PD to show maximal training outcomes. The boxing training program was feasible and safe for these patients with PD.

Mortalidade entre boxeadores

Mortality Resulting From Head Injury in Professional Boxing

Baird LC (Baird, Lissa C.)1, Newman CB (Newman, C. Benjamin)1, Volk H (Volk, Hunter)1, Svinth JR (Svinth, Joseph R.)2, Conklin J (Conklin, Jordan)2, Levy ML (Levy, Michael L.)1
NEUROSURGERY Volume: 67 Issue: 5 Pages: 1444-1450 Published: NOV 2010
Abstract:
BACKGROUND: The majority of boxing-related fatalities result from traumatic brain injury. Biomechanical forces in boxing result in rotational acceleration with resultant subdural hematoma and diffuse axonal injury.
OBJECTIVE: Given the inherent risk and the ongoing criticism boxing has received, we evaluated mortalities associated with professional boxing.
METHODS: We used the Velaquez Fatality Collection of boxing injuries and supplementary sources to analyze mortality from 1950 to 2007. Variables evaluated included age at time of death, association with knockout or other outcome of match, rounds fought, weight class, location of fight, and location of pretermial event.
RESULTS: There were 339 mortalities between 1950 and 2007 (mean age, 24 +/- 3.8 years); 64% were associated with knockout and 15% with technical knockout. A higher percentage occured in the lower weight classes. The preterminal event occured in the ring (61%), in the locker room (17%), and outside the arena (22%), We evaluated for significant changes after 1983 when championship bouts were reduced from 15 to 12 rounds.
CONCLUSION: There was a significant decline in mortality after 1983. We found no significant variables to support that this decline is related to a reduction in rounds. Rather, we hypothesize the decline to be the result of a reduction in exposure to repetitive head trauma (shorter careers and fewer fights), along with increased medical oversight and stricter safety regulations. Increased efforts should be made to improve medical supervisions of boxers. Mandatory central nervous system imaging after a knockout could lead to a significant reduction in associated mortality.

Trauma cultural, injustiça e prática de wrestling

Mexican Wrestling: Its Compensatory Function in Relation to Cultural Trauma

Lopez VM (Lopez G, Victor Manuel)1
JUNG JOURNAL-CULTURE & PSYCHE Volume: 4 Issue: 4 Pages: 33-45 Published: FAL 2010
Abstract: The invocation of pre-Hispanic mythological deities contributes the necessary element for wrestlers to endow themselves with magical, supernatural powers with which they seek to mend injustice and defeat evil. The theory of cultural complexes described by Kimbles (Singer and Kimbles 2004) suggests a way of understanding how cultural traumas still reverberate in the cultural unconscious of Mexicans. Mexican wrestling fulfills one very special function going beyond sports; its theatrical performances symbolically compensate for decades of deep-rooted injustices.

Abstract: The aim of this study was to test for differences in control of balance during the execution of the circular kick (mawashi geri) executed in two different ways. Twenty-two elite athletes in two karate specialties (kumite - sparring; kata - form) were asked to execute the preparatory phase of delivering the circular kick starting from the guard position and to maintain this position with eyes closed and the supporting leg (left and right) either stretched or slightly bent. Posturographic analysis confirmed greater efficiency/efficacy of the movement with the supporting leg slightly bent in all subjects and brought to light numerous other considerations.

Department of Physical Education and Sports Science, University of Athens. Greece. tsolakis@phed.uoa.gr
Abstract
This study investigated selected structural correlates of fencing performance. 33 elite fencers were tested on (a) selected anthropometric, flexibility, and strength-power related parameters, and (b) specific lower extremity functional fencing tests. Multiple regression showed that drop jump and thigh cross-sectional area were best predictors of lunge time and distance of squat jump on the shuttle test. When the two performance variables were expressed per Lean Body Mass, lunge time was significantly predicted only by the performance on the arm-driven counter-movement jump, while time on the shuttle test was best predicted by three noncollinear significant predictors: squat jump performance, thigh circumference, and percent body fat. Lunge time and time on the shuttle test were predicted by explosive power, while none of the nontrainable anthropometric measures or years of training seemed to be important in performance of fencing-related skills.

Abstract
The aim of this article is to elaborate a general framework for modeling dual opposition activities, or more generally, dual interaction. The main hypothesis is that opposition behavior can be measured directly from a global variable and that the relative distance between the two subjects can be this parameter. Moreover, this parameter should be considered as multidimensional parameter depending not only on the dynamics of the subjects but also on the "internal" parameters of the subjects, such as sociological and/or emotional states. Standard and simple mechanical formalization will be used to model this multifactorial distance. To illustrate such a general modeling methodology, this model was compared with actual data from an opposition activity like Japanese fencing (kendo). This model captures not only coupled coordination, but more generally interaction in two-subject activities.

Abstract: Judogi is a functional apparel. After researching into Judo history, culture, and the rules of Judogi made by IJF(International Judo Federation), in terms of safety and requirements for competition, many problems and the engineering design including body measurements, body allowance requirements, special functional patterns design, special processing technology have been studied in depth. In this study, the conversion between anthropometric data obtained from a device and actual ones has been discussed based on manual measurements, and a range of data for Judogi has been obtained by device and function equation, so the device could be better used in Judogi production. Accordingly, the engineering design project of Judogi has been made, which met the requirements of international competition standard. The key to the study was the discussion about relationship among the style, comfort and special technical requirements.

Abstract
AIM: This study was designed to assess the prevalence, distribution, and patterns of injury among athletes engaged in combat sports and compare the prevalence, pattern, and types of oral and maxillofacial trauma in these athletes.
MATERIALS AND METHODS: A total of 120 male athletes engaged in four combat sports (boxing, taekwondo, kickboxing, and Muay Thai) who had sustained bodily trauma were studied; 95 subjects with at least one traumatic injury to the face requiring treatment were referred to us by the physician team. The type of injury (facial laceration, facial fractures, jaw dislocation, etc.), site of facial injury (jaw, nose, malar bone, teeth, etc.), dental injuries (tooth fracture, displacement, luxation, and avulsion), causative sport (boxing, taekwondo, kickboxing, and Muay Thai) as well as demographic data were recorded. Injuries were examined clinically and radiographically, and treated accordingly by a specialist. Treatment data and demographics were recorded for each subject. Recorded data were assessed, and χ(2), ANOVA, and Kruskal-Wallis tests were used to statistically analyze and compare the data.
RESULTS: Of 120 subjects, 95 male subjects (79.2%), aged 18-25 years (avg. 20 years), had at least one traumatic injury to the face requiring medical treatment. These injuries included facial laceration, bone fractures (nose, mandible, and zygoma), dental injuries (displacement, luxation, fracture, and avulsion), and mandibular dislocation which were recorded in 83 (69.2%), 55 (45.1%), 53 (44.2%), and 8 (6.7%) cases respectively. Statistically significant differences were encountered among various injuries and the sports; kickboxing caused the most maxillofacial injuries and was identified as more injurious. Tooth fractures (59.7%) were the most common dental injuries, and the nose (84.7%) was the most frequently fractured facial bone. Lacerations were more common in Thai-boxers (93.3%). Injuries were significantly greater in professional rather than amateur athletes.
CONCLUSION: In this study, prevalence of facial injuries from combat sports professionals was significantly high (roughly 80%), especially in kickboxing (in part due to use of less protective gear). Because the nose and teeth sustained the most injuries, they require more attention with regard to prevention. Kickboxing was the most injurious of these combat sports and caused the most significant number of maxillofacial trauma. More safety apparel and protective guards seem warranted in athletes of combat sports if facial injury is to be prevented.

Relationship between Asian martial arts and health-related quality of life in Germany
Thomas Draxler, Herwig Ostermann and Wilfried Honekamp
Journal of Public Health

Aim
Due to the steady increase in health care costs, a greater focus on maintaining wellness and preventing health issues has been established. Historically, Asian martial arts were closely associated with maintaining healthfulness. Thus, the aim of this investigation was to determine if people who practice Asian martial arts gain any health-related quality of life benefits compared to the general population.
Subject and methods
Therefore, 343 martial artists practicing 8 varieties of martial arts answered the German standardized questionnaire 36 in a controlled setting at 24 martial arts schools (3 schools per martial art) between February 2008 and July 2008. These participants were not given information regarding the purpose of the study. Additionally, between July 2008 and December 2008, 2,512 martial artists completed an online version of the German standardized questionnaire 36.
Results
The results of those completing the questionnaire in person differed from those responding to the online questionnaire. Compared to the general public, both martial arts groups rated their health-related quality of life to be better. Of the parameters evaluated, the greater differences were observed for physical aspects of health than for psychological aspects.
Conclusion
Thus, these results indicate that participation in martial arts provides health-related quality of life benefits associated with the prevention of health problems. However, further studies are needed to understand the complex relationship between the practice of martial arts and improved health.

Changes in peak leg power induced by successive judo bouts and their relationship to lactate production.
Bonitch-Dominguez J, Bonitch-Gongora J, Padial P, Feriche B.

Department of Physical Education and Sport, University of Granada, Granada, Spain.

Abstract
Eleven male judoka, who compete at national level, were recruited with the aim of investigating changes in peak leg power as a result of successive judo bouts and their relationship with lactate production. The participants executed a force-velocity curve to determine peak power in a 90° squat exercise in concentric work. The group then participated in four 5-min judo bouts each separated by 15 min of passive rest. The power developed as a result of the load associated with the maximum peak power reached in the preliminary test was determined, for the same movement, before and after each bout. Finger capillary blood samples were taken after each bout to determine the maximum lactate concentration achieved and lactate clearance. The results showed no effect of successive bouts on peak leg power (P > 0.05) and no difference when comparing the power measured before and after each bout (P > 0.05). Maximum lactate concentration of the fourth bout was lower than that of the first (12.6 ± 3.5 and 14.6 ± 4 mmol · l(-1) respectively; P < 0.05), although there was no difference in their clearance dynamics (P > 0.05). On the basis of the results obtained, we conclude that successive judo bouts, with the structure proposed in this study, produce high acidosis levels, which have no effect on the peak power developed in the legs.

Estudo sobre respostas imunes em luta de kickboxing conduzido por docentes da EEFE-USP

EFFECT OF A KICKBOXING MATCH ON SALIVARY CORTISOL AND IMMUNOGLOBULIN A

Author(s): Moreira A1, Arsati F2, Lima-Arsati YBD2, Franchini E1, de Araujo VC3
PERCEPTUAL AND MOTOR SKILLS Volume: 111 Issue: 1 Pages: 158-166 Published: AUG 2010
Abstract: The hypothesis that salivary cortisol would increase and salivary immunoglobulin A (IgA) decrease after a kickboxing match was tested among 20 male athletes. Saliva samples collected before and after the match were analyzed. Salivary cortisol and salivary IgA concentrations (absolute concentration, salivary IgAabs) and the secretion rate of IgA (salivary IgArate) were measured by enzyme-linked immunosorbent assay. A Wilcoxon test for paired samples showed significant increases in salivary cortisol from pre- to postmatch. No significant changes were observed in salivary IgAabs or secretory IgArate and saliva flow rate. This study indicates that a kickboxing match might increase salivary concentration and thereafter it could be considered a significant source of exercise-related stress. On the other hand, the effect of a kickboxing match on mucosal immunity seems not to be relevant.

Abstract
Kim, J, Cho, H-C, Jung, H-S, and Yoon, J-D. Influence of performance level on anaerobic power and body composition in elite male judoists. J Strength Cond Res 24(X): 000-000, 2010-This study examined the relationship between 30-second anaerobic power and body composition by performance level in elite Judoists. During a 3-month period, 10 male Korean Judo national team athletes (NT), 26 male university varsity team athletes (VT), and 28 male junior varsity team athletes (JT) were assessed for 30-second anaerobic power and body composition at the Youngin University. Anaerobic power was measured using a 30-second Wingate test. Body composition was assessed via bioelectric impedance analysis in standardized conditions using BioSpace (Korean)-specific prediction formulas. All testing occurred at the beginning of the winter nonseason period but excluded a brief weight-loss period before the competition phase. Anaerobic power measures were significantly greater (p < 0.05) in NT and VT than in JT. Fat-free mass (FFM), muscle mass (MM), and total body water in JT were also greater than in VT and JT (p < 0.05). Muscle mass in VT was significantly lower than in NT (p < 0.05). Fat-free mass in NT was strongly correlated to mean and peak anaerobic power (r = 0.77, p = 0.009; r = 0.87, p < 0.001, respectively). Varsity team athletes also indicated a moderate association between FFM and peak and mean anaerobic power (r = 0.63, p < 0.001; r = 0.48, p = 0.013, respectively). However, relationship between FFM and anaerobic power was not statistically significantly correlated in JT (r = 0.14, p = 0.470; r = 0.23, p = 0.232, separately). In conclusion, our data indicated that anaerobic power is closely correlated with increase in FFM and MM and was different dependent among performance levels. Further research in the field is warranted to elucidate the Judo-specific relationship between FFM and performance.

União Europeia de Judô cria rede de centros de treinamento com vistas aos Jogos Olímpicos de Londres

EJU Sports Director Densign White unveils ambitious OTC plans
The European Judo Union has embarked on a new concept of Olympic Training Camps (OTC) which started in April of this year in the British Judo Performance Institute (BJPI) in Dartford UK and was followed by a second camp in Orenburg, Russia. The plan in 2011 is to roll out another eight camps across Europe and this number is not fixed.
Sports Director Densign White: “If there are countries who are able to organise similar camps please contact me as soon as possible.”
email: densignwhite@ukonline.co.uk

The concept of the OTC is different from the camps established over the past ten years in that the emphasis is not only on randori practice but to also help our athletes and coaches in their preparation and planning for major events building of course up to London 2012.

White: “The EJU recognises that there are a number of judoka, especially from developing countries, inside the EJU territories who have limited access to high level facilities. Quality coaching and advice and information on the latest rules changes are a necessity.”

The OTC will offer this information to the athletes and their coaches delivered by a member of the EJU referee commission who will be in attendance at each of the camps. This will be achieved by interactive group meetings and practical exercises. OTCs will also need to offer strength and conditioning possibilities and medical support.

The EJU will provide a subsidy for the top 3 athletes from the World Ranking List. This list will be announced soon.

Sports Director White: “The EJU coaches commission (*), which was formed earlier this year, has a critical role in the success of the OTC and we would encourage all coaches to work with your commissioners and to give feedback because we are striving to give you a positive experience that will ultimately lead to Olympic success for all of our EJU family members.”
“The close working collaboration between referees and coaches is as important to success on the tatami as all of the physical preparation and that is why in addition to the OTC concept we will continue to have a joint referee and coach seminar next year again.”

The OTC starts in Madrid 18th October and is open to all EJU athletes.

White added: “Thank you all for your support so far and I am sure that by working together we can all achieve our dreams and aspirations for London in 2012.”

(*) coach commission members are:
Ezio Gamba (RUS)
Maarten Arens (NED)
Patrick Roux (GBR)

Abstract
Magnesium (Mg) deficiency strongly affects muscle performance. In judo, many athletes often undergo impressive weight changes associated with severe dehydration. Common practices used by athletes to achieve a target weight can lead to Mg deficit. This study aimed to understand the impact of Mg changes on strength from periods of weight stability to prior to competition in a sample of elite judo athletes who differentially changed their intracellular water (ICW). The sample consisted of 20 elite male judo athletes. Subjects were divided according to ICW changes: losses below 2% and losses equal to or above 2%. Mg was measured in serum, red blood cells and urine by atomic absorption spectrophotometry. ICW was calculated as the difference between total-body water and extracellular water using dilution techniques. Maximal handgrip strength was evaluated using Jamar Hydraulic Hand Dynamometer. Upper-body power was determined in a bench press. Higher ICW decreases were associated with higher strength reductions, though our results suggest that an increase in red blood cell Mg might attenuate those strength reductions in athletes who decrease the ICW compartment. As Mg losses can be considerable and intake is frequently insufficient, athletes should consider supplementation, especially during periods of weight reduction.

Abstract
Santos, L, González, V, Iscar, M, Brime, JI, Fernandez-Rio, J, Egocheaga, J, Rodríguez, B, and Montoliu, MA. A new individual and specific test to determine the aerobic-anaerobic transition zone (Santos Test) in competitive judokas. J Strength Cond Res 24(9): 2419-2428, 2010-The main goal of this research project was to design a specific, simple, and noninvasive field test to determine the individual aerobic-anaerobic transition zone in judokas. Our aim was to develop a field test as close as possible to real judo combat. Eight state- and national-level judokas participated in the study. To find the reliability of our test, all subjects repeated the same test under the same conditions within a 7-day period. Because the results were positive, we tested the validity of our proposal using a laboratory test that possessed the same characteristics. On both tests, the same parameters were studied. The mean data obtained in the laboratory test were as follows: maximum heart rate (HRmax): 198.2 +/- 3.9 b.min, HR at the anaerobic threshold: 170.3 +/- 5.7 b.min, percentage of HRmax at which the anaerobic threshold appears: 85.9 +/- 2.9%, lactate max: 14.6 +/- 1.4 mmol.L, lactate threshold: 4 +/- 0.3 mmol.L, and &OV0312;O2max: 58.3 +/- 4.4 ml.kg.min. The mean data obtained in the field test were as follows: HRmax: 199.7 +/- 1.8 b.min, HR at the anaerobic threshold: 169.7 +/- 2.7 b.min, percentage of HRmax at which the anaerobic threshold appears: 85.0 +/- 1.8%, lactate max: 17.0 +/- 2 mmol.L, lactate threshold: 4.0 +/- 0.3 mmol.L, and &OV0312;O2max: 59.8 +/- 3.6 ml.kg.min. There were no significant differences between the data obtained on both tests in any of the parameters evaluated, except for the lactate maximum. Therefore, we can conclude that our field test is a useful tool for judo training.

Análise do ECSS feita por W Hopkins

O Dr. Hopkins fez uma análise bastante interessante dos trabalhos apresentados no ECSS deste ano, ao qual estivemos presentes. Ele apresenta algumas dicas importantes para melhorar a dissertação do resumo, bem como as apresentações orais e de pôsteres. Também apresenta uma lista com o que ele considerou os trabalhos mais relevantes na área de rendimento esportivo. Nas lista, dois trabalhos da EEFE e um nosso (resultados da Bianca, apresentados pelo Fabrício). A referência ao nosso é curta, mas é um importante feedback do que temos feito.

Plasma nesfatin-1 and glucoregulatory hormone responses to two different anaerobic exercise sessions.
Ghanbari-Niaki A, Kraemer RR, Soltani R.

Exercise Biochemistry Division, Faculty of Physical Education and Sports Sciences, University of Mazandaran, 47416-95447, Babolsar, Mazandaran, Iran, aghanbariniaki@gmail.com.

Abstract
Nesfatin-1 is a recently discovered anorectic protein derived from posttranslational processing of the nucleobindin 2 (NUCB2) gene. It is expressed in adipose tissue and is also found in plasma. Nesfatin-1 expression is significantly affected by nutritional status and its actions may be involved in the inhibition of the orexigenic effect of ghrelin. Although the effects of physical exercise on several anorectic and orexigenic hormones have been reported, no studies have investigated its effects upon circulating concentrations of nesfatin-1. We investigated the effects of acute strenuous interval exercise and circuit exercise on nesfatin and other hormones affected by metabolic stress. Fourteen provincial and national level young male-kickboxing volunteers participated [age 20.71 +/- 2.6 years, height 176.6 +/- 2.8 cm, body weight 67.2 +/- 3.3 kg, and body mass index (BMI) 21.56 +/- 1.42 kg/m(2)]. After an overnight fast, responses to a running-based anaerobic sprint test (RAST; 7 sets of 6 x 35 m every 10 s with 1 min rest in between sets) and a non-combat kickboxing session (NCKB; 7 sets of 6 techniques, 20 s per technique with 1 min rest in between sets) were determined. Venous blood samples were collected before, immediately after, and 45 as well as 95 min following the exercises. Plasma GH, insulin, glucose and lactate concentrations significantly increased immediately following the RAST and NCKB protocols, however, plasma nesfatin-1 concentrations were not significantly altered. Higher plasma cortisol and glucose concentrations occurred in response to the RAST compared with the NCKB protocols. Although the exercise protocols elicited metabolic stress that significantly altered circulating glucoregulatory hormones, plasma glucose and lactate, there was no significant change in plasma nesfatin-1. A lack of nesfatin-1 response to the exercise protocols may be partially due to the fasting condition.

Advancements in the Scientific Study of Combative Sports
Editors: Jason E. Warnick and W. Daniel Martin (Arkansas Tech University, Russellville, AR )
Book Description:
Combative sports, like boxing and the martial arts, have been a mainstay of competitive athletics throughout the history of mankind. While these sports are controversial in nature, the athletic endeavors of boxing and mixed martial arts have become multi-billion dollar industries enjoyed by millions of fans around the world. Research on these sports has spanned many domains including psychology, sociology, physiology, sports medicine and biomechanics. Each of these approaches to the topic of combative sports has provided many interesting findings. Further, each field has offered advancements that have improved the sports’ training, judging, safety, and associated medical care. However, until now, research within each of these domains has been published in journals specifically targeting scholars in that field. Thus, interdisciplinary research on this topic has remained rare and has seldom been promoted. This book seeks to provide a central outlet for the current research on combative sports, provoke interdisciplinary approaches to the field, and provoke further research and advancements on the topic. For scholars interested in combative sports, various aspects (e.g., mental, physical and cultural) of athletics and sports medicine, this book will be useful as both a starting point and a reference guide for the field.

Body Composition and Power Changes in Elite Judo Athletes.
Silva AM, Fields DA, Heymsfield SB, Sardinha LB.

Faculty of Human Kinetics, Technical University of Lisbon, Exercise and Health Laboratory, Cruz-Quebrada, Portugal.

Abstract
The purpose of this study was to analyse the association between body composition changes, from a weight stable period to prior competition, on upper-body power in judo athletes. 27 top-level male athletes were evaluated at baseline (weight stable period) and 1-3 days before competition, with a time difference of approximately 1 month. Total body and extracellular water were estimated by dilution techniques (deuterium and bromide, respectively) and intracellular water was calculated as the difference. Body composition was assessed by DXA. A power-load spectrum was used to assess upper-body power output in a bench-press position. Comparison of means, bivariate, and partial correlations were used. Results indicate that though no significant mean changes were found in body composition and upper-body power, individual variability was large. Among all body composition changes, only total-body water (r=0.672; p<0.001) and intracellular water (r=0.596; p=0.001) were related to upper-body power variation. These associations remained significant after controlling for weight and arm lean-soft tissue changes (r=0.594, p=0.002 for total-body water; r=0.524, p=0.007 for intracellular water). These findings highlight the need for tracking total-body water, specifically the intracellular compartment in elite judo athletes in order to avoid reductions in upper-body power when a target body weight is desired prior to competition.

An Examination of Judging Consistency in a Combat Sport
Tony Myers, Newman University College
Alan M. Nevill, University of Wolverhampton
Yahya Al-Nakeeb, Newman University College


Abstract
Two related studies compared the consistency of two different methods of interpreting and applying scoring criteria in Muay Thai that are normally used by officials in the UK and that are used by officials in Thailand. In the first study, levels of consistency were determined by comparing judge's scores (n=270) from forty-five bouts judged by UK officials and forty-five judged by Thai officials. In the second study the original forty-five bouts judged by UK judges were compared with forty–five bouts judged by UK officials using Thai judging criteria. Consistency was examined in both studies using two methods. The first method compared differences in the range of the highest vs. lowest points awarded by judges for each bout. The second method compared homogeneity of variance between judges' scores. Results suggested that the Thai officials were more consistent than their UK trained counterparts but also that UK judges were more consistent when adopting the Thai judging criteria. It was suggested that the use of very clearly defined criteria and concrete operationalization of otherwise subjective concepts used in applying the system used in Thailand was the main reason for the findings.

A ingestão de cafeína não melhora o desempenho de atletas de judô
Lucas Adriano Pereira, Edílson Serpeloni Cyrino, Ademar Avelar, Alexandre Queiroz Sergantin, Juliana Melo Altimari, Michele Caroline de Costa Trindade, Leandro Ricardo Altimari


Resumo


O objetivo do presente estudo foi investigar os efeitos ergogênicos da ingestão de cafeína, sobre o desempenho motor de atletas de judô feminino. Participaram do estudo 13 atletas do sexo feminino (17,6 ± 1,6 anos, 58,3 ± 11,4 kg, 162 ± 4,1 cm, 22,5 ± 4 kg/m2), vinculadas à Federação Paranaense de Judô, por pelo menos dois anos. O desempenho motor foi avaliado mediante a utilização do Special Judô Fitness Test (SJFT), a partir do qual foi analisado o número de arremessos em cada bloco, número total de arremessos, frequência cardíaca (FC) final e de recuperação e o índice no SJFT. Os sujeitos foram testados em duas condições, após ingestão de cafeína (6 mg.kg-1) ou placebo (dextrose) 60 minutos antes dos testes, em um delineamento duplo-cego, cruzado. O número de arremessos em cada bloco não diferiu entre as condições cafeína (CAF) e placebo (PL) (Bloco A: 4,53 ± 0,51 CAF e 4,46 ± 0,51 PL; Bloco B: 8,3 ± 0,63 CAF e 8,23 ± 0,72 PL; Bloco C: 7,23 ± 0,59 CAF e 7,46 ± 0,77 PL), bem como o número total de arremessos (20,07 ± 1,18 CAF e 20,15 ± 1,67 PL), FC (Final: 190,3 ± 9,63 bpm CAF e 190,69 ± 9,19 bpm PL; Recuperação: 162,07 ± 13,78 bpm CAF e 164,3 ± 9,64 bpm PL) e índice no SJFT (17,59 ± 1,4 CAF e 17,75 ± 1,98 PL). A ingestão de cafeína não melhorou o desempenho durante atividade de alta intensidade e curta duração em lutadores de judô.

The need of a weight management control program in judo: a proposal based on the successful case of wrestling.
Artioli GG, Franchini E, Nicastro H, Sterkowicz S, Solis MY, Lancha AH Junior.

Abstract
ABSTRACT: Judo competitions are divided into weight classes. However, most athletes reduce their body weight in a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast weight reduction, athletes use a number of aggressive nutritional strategies so many of them place themselves at a high health-injury risk. In collegiate wrestling, a similar problem has been observed and three wrestlers died in 1997 due to rapid weight loss regimes. After these deaths, the National Collegiate Athletic Association had implemented a successful weight management program which was proven to improve weight management behavior. No similar program has ever been discussed by judo federations even though judo competitors present a comparable inappropriate pattern of weight control. In view of this, the basis for a weight control program is provided in this manuscript, as follows: competition should begin within 1 hour after weigh-in, at the latest; each athlete is allowed to be weighed-in only once; rapid weight loss as well as artificial rehydration (i.e., saline infusion) methods are prohibited during the entire competition day; athletes should pass the hydration test to get their weigh-in validated; an individual minimum competitive weight (male athletes competing at no less than 7% and females at no less than 12% of body fat) should be determined at the beginning of each season; athletes are not allowed to compete in any weight class that requires weight reductions greater than 1.5% of body weight per week. In parallel, educational programs should aim at increasing the athletes', coaches' and parents' awareness about the risks of aggressive nutritional strategies as well as healthier ways to properly manage body weight.

Acute Effects and Postactivation Potentiation in the Special Judo Fitness Test.
Miarka B, Del Vecchio FB, Franchini E.

Martial Arts and Combat Sports Research Group, Sport Department, School of Physical Education and Sport, University of São Paulo, Brazil.

Abstract
Miarka, B, Del Vecchio, FB, and Franchini, E. Acute effects and postactivation potentiation in the special judo fitness test. J Strength Cond Res 24(x): 000-000, 2010-The purpose of this study was to compare the acute short-term effects of (1) plyometric exercise, (2) combined strength and plyometric exercise (contrast), and (3) maximum strength performance in the Special Judo Fitness Test (SJFT). Eight male judo athletes (mean +/- SD, age, 19 +/- 1 years; body mass, 60.4 +/- 5 kg; height, 168.3 +/- 5.4 cm) took part in this study. Four different sessions were completed; each session had 1 type of intervention: (a) SJFT control, (b) plyometric exercises + SJFT, (c) maximum strength + SJFT, and (d) contrast + SJFT. The following variables were quantified: throws performed during series A, B, and C; total number of throws; heart rate immediately and 1 minute after the test; and test index. Significant differences were found in the number of throws during series A: the plyometric exercise (6.4 +/- 0.5 throws) was superior (p < 0.05) to the control condition (5.6 +/- 0.5 throws). Heart rate 1 minute after the SJFT was higher (p < 0.01) during the plyometric exercise (192 +/- 8 bpm) than during the contrast exercise (184 +/- 9 bpm). The contrast exercise (13.58 +/- 0.72) resulted in better index values than the control (14.67 +/- 1.30) and plyometric exercises (14.51 +/- 0.54). Thus, this study suggests that contrast and plyometric exercises performed before the SJFT can result in improvements in the test index and anaerobic power of judo athletes, respectively.
