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.

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.

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.

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).

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.
