Abstract

BACKGROUND:

Young athletes have more nutritional needs than other adolescents because of physical activity and physical development. Optimal athletic performance results from a combination of factors including training, body composition, and nutrition. Despite the increased interest in nutrition and use of dietary supplements to enhance performance, some athletes might be consuming diets that are less than optimal. In wrestling it is common practice to optimize one's body composition and body weight prior to a competition season. This often includes a change in dietary intake or habits.

METHODS:

Twenty-eight wrestlers, between the ages of 17 and 25 years, participated in this study. Dietary intakes of micro and macro nutrients were collected by face-to-face interview, structured food frequency questionnaire (FFQ). Dietary intake of energy, carbohydrates, fats and proteins and micronutrients was evaluated.

RESULTS:

Mean intakes of energy, carbohydrates, proteins and fat were higher than recommended dietary allowances (RDA). The mean intakes of all vitamins and minerals were higher than the RDAs in these wrestlers, except for vitamin D, biotin, zinc, iodine, chrome and molybdenum.

CONCLUSIONS:

On the basis of our results, nutritional education should be given to these subjects and their families for promoting healthy eating habits.

Abstract

BACKGROUND:

After exercise, recovery is very essential in professional sport. Athletes use sport beverages to enhance endurance and physical performance. The purpose of this study was to examine the effects of Dough versus non-alcoholic beer and carbohydrate (CHO) fluid on performance, lipids profile, inflammatory biomarkers after Running-based Anaerobic Sprint Test (R.A.S.T) in Taekwondo players.

METHODS:

This study was conducted as repeated measures crossover design with 22 men Taekwondo player. Subjects completed standard protocol R.A.S.T so that immediately and 1 h posterior R.A.S.T protocol received number 1 beverage. Subjects spend 2 h recovery periods. Second and third sessions trial were similar to prior trial, separated by at least 4 days, instead of number 1 beverage, participants received number 2 and number 3 beverage.

RESULTS:

Data showed that average pre- and post-recovery in C-reactive protein (CRP) or Dough significantly decreased (P < 0.05), while for CHO drink and non-alcoholic beer, were not statistically significant. Moreover, the mean pre- and post-recovery in VO2 max for Dough and non-alcoholic beer significantly increased, but for other beverages, there was no significant difference (P > 0.05). About mean pre- and post-recovery in low density lipoprotein (LDL) and high density lipoprotein (HDL) there were no significant differences in all three beverages. Besides, amount of CRP was significant between three beverages (P < 0.05). There were no other within-subject differences for any of the other variables measured, including HDL, LDL, and VO2max. In addition, no significant different (P > 0.05) in dietary intake were observed between three treatment periods.

CONCLUSIONS:

Dough was effective in reducing LDL and reducing inflammatory biomarkers including CRP with little effect on performance in subjects.

Contribuição energética no boxe

 2013 May 20. [Epub ahead of print]

The Energetics of Semi-Contact 3 x 2 min Amateur Boxing.

Source

Centre for Sport and Exercise Science, Biological Sciences, University of Essex, Colchester, UK.

Abstract

The energy expenditure of amateur boxing is unknown.

PURPOSE:

Total metabolic cost (Wtot) as an aggregate of aerobic (Waer), anaerobic lactic (W[lactate]) and anaerobic alactic (WPCr) energy of a 3x2 min semi-contact amateur boxing bout were analysed.

METHODS:

Ten boxers (mean±SD (lower/upper 95% confidence intervals) age: 23.7±4.1 (20.8/26.6)yrs; height: 180.2±7.0 (175.2/185.2)cm; body mass: 70.6±5.7 (66.5/74.7)kg) performed a semi-contact bout against hand held pads created from previously analysed video footage of competitive bouts. Net metabolic energy was calculated using respiratory gases and blood [lactate].

RESULTS:

Waer 526.0±57.1 (485.1/566.9)kJ was higher (p<0.001) than WPCr 58.1±13.6 (48.4/67.8)kJ. W[lactate] 26.2±7.1 (21.1/31.3)kJ was lower (p<0.001) than Waer and WPCr. A ~70kJ fraction of the aerobic energy expenditure reflects re-phosphorilation of high energy phosphates during the breaks between rounds which elevated Wtot to ~680kJ with relative contributions of 77% Waer, 19% WPCr and 4% W[lactate].

CONCLUSIONS:

The results indicate that the metabolic profile of amateur boxing is predominantly aerobic. It also highlights the importance of a highly developed aerobic capacity as prerequisite of a high activity rate during rounds and recovery of the high energy phosphate system during breaks as interrelated requirements of successful boxing.

Para entender a vida universitária no século XXI, às vezes é preciso voltar a 1979 : )

http://www.ichsp.com/ich_textos_II_05.htm

Bressan E. 2001: The Profession is dead – was it murder or suicide? Quest, 1979, 31(1), 77 – 82.


It is 2001 and on campuses all over the United States, the profession of physical education is acknowledged as officially dead. Mention of its name is removed from all college catalogs, and the few remaining members of its faculty are reassigned to various other duties within the colleges and universities. The fact of this profession’s demise is accepted, but the method of its death is not fully clear. Is it a case of murder or suicide? 

The Case for Murder 

Cases of murder are usually approached through the identification of a motive. Who wanted the profession dead? Who would think they might profit from its demise? Close relatives often become prime suspects in these instances, so let us examine the behavior of the theoretical discipline that ostensibly supported this profession. 

1. In the late 1960s and early 1970s there was a proliferation of graduate programs that focussed on the development of "disciplinary skills of inquiry." These programs in many cases refused to offer any professional training of its students. 

2. In the late 1970s undergraduate programs in the "theoretical discipline" were developed. Students of these programs studied "cross-disciplinary" concepts and developed expertise in formulating and solving cross-disciplinary problems. 

3. By the 198Os college and university faculties were composed primarily of young members fully prepared as researchers in the discipline. Each time that matters of curriculum and pedagogy came up, they supported the expansion of disciplinary studies at the expense of professional studies. 

4. By the 1990s the members of the discipline had fully taken over all national and regional organizations. Hiring criteria at the colleges and universities revolved about the production of publications and the ability to attract grant monies. The profession was seen as an anti-intellectual faction that was incompatible with the erudite goals of the discipline. In an effort to "purify" themselves, these faculties re-assigned all of their professional preparation responsibilities (and faculty) to colleges of education. 

5. Once re-located in the college of education faculty, the profession of physical education came under instant attack. Its discrete methods courses were taken away. Many credit hours of participation in physical activity were replaced with courses in general educational theory. Any attempt by the out-numbered physical educators to protest was met with challenges of "prove it" and ‘where is your theoretical support." When the professionals turned to the disciplinarians for such proof and support, they were met with silence. The discipline was not concerned with questions of applied research or pedagogical difficulties. It was dealing only with "basic research" regarding physiological, sociological or psychological questions. 

6. The late 1990s saw the few remaining professional physical educators retire from college teaching. They were replaced by new faculty that "fit in" with the structure of the college of education. Certification still occurred in physical education, but there were in fact no specific courses dealing with its content. Theories of education were studied and then, quite separately, theories regarding human movement studied. 

Several aspects of this presentation point to the murder of the profession by the discipline. First, the motive. Members of the discipline took over power on the faculties. The constant reduction of professional interest led to the generation of new courses (hence new faculty) in the discipline. The disciplinarians—who had little or no teaching experience themselves—were offended by the presence of "practical problems" in their midst. Second, the opportunity. They saw what they considered their "big chance" for academic respectability and took it— they forced the profession out and into a situation in which there was no chance for survival. That is murder. 

The Case for Suicide 

Perhaps the murder explanation is too easy. Since we actually found no "smoking gun" in the hand of the discipline, the possibility of suicide must not be overlooked. Suicide is considered self-induced death. What actions by the profession may have brought its death upon itself? 

1. In the late 1960s and early1970s professionals avoided the responsibility of generating their own body of knowledge. There was no opportunity to evolve sophisticated programs without such a base in knowledge and technology, so the future of the profession on the college level was doomed. 

2. In the late 1970s the development of noncertifying undergraduate major programs was allowed to be effected by members of the discipline alone. Despite their knowledge of human movement and curriculum, the professionals did not lend their expertise to program development. By leaving program decisions to inexperienced disciplinarians. They created a climate in which they presented themselves as uninformed and disinterested. They were inviting a separation. 

3. By the 1980s, professionals felt so overwhelmed by the intellectual banter that marked most faculty meetings that they accepted their status as subordinate to the discipline. They allowed disciplinarians to represent them in faculty senates and campus committees. They withdrew entirely from the academic community. 

4. By the 1990s the members of the profession all but dropped out of national and regional organizations. They claimed that the programs had become too theoretical and difficult to understand. Whenever asked if they would like to put on a program, they replied that they did not have the time what with all of their practical responsibilities. 

5. The re-assignment of the profession to colleges of education was not fought. The profession had long since given up attempts to share its problems with the discipline or to assist the discipline when it did make attempts at applied research. The profession was unwilling or unable to express its rationale for remaining outside the general education community. 

6. The late 1990s brought "blessed retirement" to the remaining embittered professionals. They had accepted their subordinate role in education. Their inability to elucidate their unique contributions to education had left the college faculties with no other choice but to redistribute their credit hours. 

The portrait here is of a profession that is asking for its own demise—allowing itself to be bullied, even inviting it. The skills needed to survive in the academic community are reasonably well known, yet the unwillingness of professionals to acquire and employ those skills is the manifestation of a death wish. That is suicide. 

There is some pronounced irony in this case—perhaps a touch of justice. If the profession dies on the collegiate level, the deterioration of public school programs will follow. This in turn may lead to the removal of physical education from school curricula, hence its removal as a "major" in colleges of education. This would result in a severe reduction in the population of students taking courses in the "discipline." Put into such an enrollment crunch, members of the discipline will have to align themselves more closely with the "parent disciplines" of psychology, sociology, etc. Their research questions methods, financial support, and students will become "psychologists interested in movement" or "sociologist interested in sport." To any administration, this would be a clear sign that there is no unique discipline there at all, and maintaining it as a separate faculty is a waste of funds. Then, the discipline will be dead as well. Where is the irony? Well, if the discipline murders the profession, it is actually committing suicide. If the profession commits suicide, it is committing (albeit post mortem) the murder of the discipline. 

Do We Treat the Symptoms, or The Cause? 

We can spend our next 30 years trying to remedy the difficulties caused by the schism between physical education as a discipline and physical education as a profession. Numerous proposals have been to foster peaceful coexistence: theory into practice journals, research, development task forces that would produce applied research, advanced graduate degrees in the professional aspects of physical education, the provision of methods courses in college teaching for aspiring disciplinarians, an improvement in the disciplinary background offered in teacher certification programs, and so on. 

Treating the symptoms of a disorder, however, is only an acceptable procedure when either the root cause of the malady is unknown or when we have no way of effectively dealing with it. I would like to propose that the schism between our profession and discipline is an artificial one – one that we have created through careless philosophical examination and the inertia of his— tone-al precedent. 

The primary philosophical misconception surrounding our difficulties is the acknowledgment of two "disciplines" that deal with physical education: the "academic" discipline that is concerned with knowing a phenomenon through the processes of logic, reason, and controlled experimentation, and the "professional" discipline that is concerned with knowing how a phenomenon may be controlled and manipulated through the application of specific skills and technology. These are in fact two of Aristotle’s Classes of Disciplines (Schwab, 1967). These two types of disciplines are antithetical – one is the theoretical, the other the practical. It should follow, then, that the members of the respective disciplines would find many of their interests, needs and modes of expression antithetical. Such a schism – were it an accurate one – would be natural and appropriate for physical education. It is, however, an arbitrary division and its origin can be traced to the scramble to identify a disciplinary basis that characterized physical education in the 1960s. 

Physical education was put in the position of having to justify its existence in academic circles. The pressure was intense and time did not allow for rigorous philosophical examination of the consequences of many proposals. It should not be surprising that the structures of other academic disciplines became immediately attractive. Sociology, physiology, psychology, etc., were all academic disciplines that dealt with questions which held interest for physical educators. These disciplines also recognized the possibility that some individuals would want to become teachers in these areas. The potential for analogy to physical education was almost too good to be true. So the model of physical education as "Two Disciplines" was conceived. It was accepted in most quarters – not because it was right, but because it sounded right. It promised both academic and professional rationale. 

The current situation in physical education holds the seeds for the "death scene" offered at the beginning of this article. It is almost impossible for antithetical interests to co-exist in any effective system. Acceptance of dual disciplines must ultimately result in dual organizations. The impending "death" of one or both organizations need not follow, of course, but fundamental changes in their structures and functions would be required for survival. 

There is an alternative, however, that remains almost religiously ignored. It is based upon the position that an initial mistake was made in the conception of physical education as both an academic discipline and a professional discipline. Instead, physical education is a Productive Discipline like fine arts, engineering, or architecture. All of the disciplines in this class are concerned with the "making" of their phenomena (Schwab, 1967). Unlike an academic discipline that requires content that is reasonably static and predictable, a productive discipline deals with malleable subject matter. Unlike a professional discipline that is concerned with the control and modification of its given material, a productive discipline seeks to release the inherent potential of its material in a wide variety of contexts and situations. 

The acceptance of physical education as a productive discipline would force a reconceptualization of both our substance (precisely what we deal with) and our syntax (the methods of discovery, criteria for proof, means for implementation of knowledge. etc.). The human performance of movement and the kinds of questions relating to that performance would become the substantive structure. This implies a value position on "what questions are worth pursuing" that an academic discipline need not invoke, for if the enhancement of the subject (i.e., performed human movement) is the thrust of a productive discipline, then relevant questions are those that addresses the enhancement of performance. The acceptable syntax for such a discipline would adhere to an intellectual ethic that demands the enhancement of the inherent potential of its material (i.e., an individual who is moving). Within this redefinition physical education establishes itself as a single productive discipline that is concerned with the making movement patterns that help realize the inherent potential of each individual as a performer. Basic research exists only to support the generation of designs and formats to facilitate this process. Methods and techniques are seen only as tools to be continuously refined and replaced according to the expanded knowledge of individual potential revealed in research. Lest this sound like a simple "sandwich" of an academic with a professional discipline, take note: the individual who produces knowledge is also a designer—he takes his knowledge and structures it into realistic contexts so that it may be observed as it actually manifests itself in the performance of movement. The worth of that knowledge—not its truth necessarily, but its worth would be assessed upon its contribution to the purpose of the discipline—the enhancement of individual potential in movement. 

The implications are equally compromising for the current "professional disciplinarian." The knowledge of techniques and methods is insufficient, for the "teacher" must be a designer as well. He must be able to take basic knowledge and propose alternative patterns for including that information in realistic contexts. The worth of his efforts is determined by his accurate and continuous incorporation of new knowledge in the attempt to enhance individual potential in movement. Both the "scholars" and the ‘practitioners" in a productive discipline must be skilled at designing environments where individual performers seek their own potential. Both the "scholars" and "the practitioners" must keep abreast of knowledge about the attainment of human movement potential and be able to offer new environmental designs to reflect advances in that knowledge. The major difference, then, between a "scholar" and a "practitioner" would be the amount of time the former spends seeking new knowledge while the latter is implementing current designs. The two responsibilities require the same skills hut in different quantities. 

Is such a proposal of a productive discipline—were it deemed desirable—impossible to implement? Not at all. Go to the School of Engineering or School of Architecture at your own institution. Examine their criteria for the employment of faculty, their standards for promotion and tenure, the nature and type of research they value. Take a look at the manner in which they organize their undergraduate and graduate programs. You may find you are much more comfortable with their schemes than any you have seen proposed for physical education. Schwab (1967) noted that one of the most difficult problems in education is that we try to deal with every discipline as though it were theoretical. Human movement is not theoretical—it is actual. It is performed, it is "made’ by human beings. It is intimately productive . . . and so should we be.

Abstract

Context: The effects of dehydration induced by wrestling-related weight-cutting tactics on clinical concussion outcomes, such as neurocognitive function, balance performance, and symptoms, have not been adequately studied. Objective: To evaluate the effects of dehydration on the outcome of clinical concussion measures in National Collegiate Athletic Association Division I collegiate wrestlers. Design: Repeated-measures design. Setting: Clinical research laboratory. Patients or Other Participants: Thirty-two Division I healthy collegiate male wrestlers (age = 20.0 ± 1.4 years; height = 175.0 ± 7.5 cm; baseline mass = 79.2 ± 12.6 kg). Intervention(s): Participants completed preseason concussion baseline testing in early September. Weight and urine samples were also collected at this time. All participants reported to prewrestling practice and postwrestling practice for the same test battery and protocol in mid-October. They had begun practicing weight-cutting tactics a day before prepractice and postpractice testing. Differences between these measures permitted us to evaluate how dehydration and weight-cutting tactics affected concussion measures. Main Outcome Measures: Sport Concussion Assessment Tool 2 (SCAT2), Balance Error Scoring System, Graded Symptom Checklist, and Simple Reaction Time scores. The Simple Reaction Time was measured using the Automated Neuropsychological Assessment Metrics. Results: The SCAT2 measurements were lower at prepractice (P = .002) and postpractice (P < .001) when compared with baseline. The BESS error scores were higher at postpractice when compared with baseline (P = .015). The GSC severity scores were higher at prepractice (P = .011) and postpractice (P < .001) than at baseline and at postpractice when than at prepractice (P = .003). The number of Graded Symptom Checklist symptoms reported was also higher at prepractice (P = .036) and postpractice (P < .001) when compared with baseline, and at postpractice when compared with prepractice (P = .003). Conclusions: Our results suggest that it is important for wrestlers to be evaluated in a euhydrated state to ensure that dehydration is not influencing the outcome of the clinical measures.

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.
Conclusions: 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.

O CAMINHO-VIA MARCIAL NO CINEMA JAPONÊS: ESTUDOS SOBRE A REPRESENTAÇÃO DO BUDŌ EM SANSHIRO SUGATA E KURO OBI

Marcel Farias de Sousa

Resumo


Este trabalho objetiva realizar uma reflexão sobre a presença do Budō no cinema japonês. Para tal, escolheu-se a metodologia de análise de filmes proposta por Penafria (2009). Como procedimento complementar, foram escolhidas duas obras cinematográficas japonesas de distintos momentos: Sanshiro Sugata (1943) e Kuro Obi (2007), mas que retratam o período histórico de intensas transformações desta sociedade, demarcados pelo período Meiji (1868-1912), Taishō (1912-1926) e Shōwa (1926 até o presente). Diante da apropriação parcial, centrada na dimensão técnica-estética das práticas marciais orientais, considerou-se que estas obras demonstram os princípios éticos-filosóficos presentes no judō e karate dō formados pela religiosidade e moralidade que sustentavam a sociedade japonesa daquele período e que legitimam os elementos constituintes da identidade nacional deste país.

O ENCONTRO COM A CAPOEIRA NO TEMPO DA VADIAÇÃO

Flávio Soares Alves

Resumo


O artigo é parte de uma tese de doutorado que investigou às práticas de constituição/invenção do capoeirista. Acompanhamos grupos de capoeira Angola e Regional em São Paulo, Piracicaba, Botucatu e Jaú. O princípio da cartografia (DELEUZE; GUATTARI, 1995a) mobilizou a investigação, permitindo a constituição dos diários e entrevistas, como movimentos constituidos entre pesquisador e sujeitos. A escritura da pesquisa serviu-se das relações e singularidades descobertas nestes movimentos para forjar o exercício analítico, compreendendo-o como multiplicidade. Observamos que em meio ao tempo da vadiação, a capoeira surge como movimento na espreita dos acontecimentos que se desdobram da prática do treino e do exercício da convivência – cultivos da tradição. Tais práticas de cultivo exigem certa disposição ao imprevisível, sem a qual o aprendiz não encara o desafio de tomar a capoeira como prática de sua existência.

Condicionamento físico para atletas de MMA


Fabrício Boscolo Del Vecchio and Emerson Franchini (2013) SPECIFICITY OF HIGH-INTENSITY INTERMITTENT ACTION REMAINS IMPORTANT TO MMA ATHLETES’ PHYSICAL CONDITIONING: RESPONSE TO PAILLARD (2011)1. Perceptual and Motor Skills: Volume 116, Issue , pp. 233-234.
doi: 10.2466/25.05.PMS.116.1.233-234

Summary.—This response to Paillard (2011) focuses on the intermittent nature of mixed martial arts (MMA). It also emphasizes that the main goal of MMA athletes is to win by knockout or submission and that these actions normally are high-intensity actions or preceded by high-intensity actions. Additionally, there is evidence that high-intensity intermittent exercise protocols are able to improve aerobic fitness. It is important only to adjust physical training to the athletes’ techniques and tactics.

ABSTRACT
The aim of this study was to determine the most frequent technical errors, and their associated behavioural sequences, in the judo throw osoto-gari, proposing improvements to the way in which judo is taught and learnt. Inexperienced students (n=55, 30 males and 25 females; M=24.8 years, SD=2.3) from the Faculty of Educational and Sports Science at the University of Vigo (Spain) were recorded on digital video while performing the technique. The results of this systematic observational study based in descriptive statistics and the sequential analysis of temporal patterns were obtained via the THEME v.5 software, revealing a series of typical errors when learning the osoto-gari. Specific sequences of errors were identified being able to propose motor tasks and teaching-learning processes to ensure that novices successfully learnt the osoto-gari technique. Recommendations about the use of feedback are also provided.

Background and Study Aim: Although judo is a sport with great tradition that is practised worldwide, the state of the art and scientific advances have not been analysed from a bibliometric point of view up to now.
The aim of the present article is the status of the scientific production, collaboration, and impact of scientific papers on judo, as well as the most active research groups working on this topic.
Material and Methods: Our analysis was based on documents retrieved from the Science Citation Index and Social Science Citation Index. Bibliometric analysis and network construction were performed using Histcite and Bibexcel software.
Results: As a result, 383 original papers and scientific reviews were retrieved from 162 journals in 78 Web of Science® categories.Archives of Budo had the highest number of articles (56), and International Journal of Sports Medicine had the highest number of citations (192). More than half of the articles were within the area of sports science. The co-authorship network (threshold ≥3 articles) enabled us to identify 6 clusters of authors written in partnership. The citation network was formed mainly by 14 authors.
Conclusions: Although research on judo is still at an early stage and has a lower profile than other sports, its development has potential interest to many scientific fields and sports in general. Judo research is mainly published in journals covering sport science and sport medicine topics; the latter being the most cited ones. The co-authorship networks tended to be centralized, with a single lead author, while citation networks between authors were usually directed towards other areas of research.

Segundo texto da série "18 anos de pesquisa..."


Esse eu só tinha em word, mas procurando um outro texto (do Saeki, 1994, q perdi pela décima vez, rs), achei no google books:

Emerson Franchini; Fabrício Boscolo Del Vecchio. Tradição e modernidade no judô: histórico e implicações. In: Ética e compromisso social nos Estudos Olímpicos. .Porto Alegre: Editora PUC-RS, 2007. p. 121-145.

Mais um texto com material de apoio no site da Associação Grand Masters e Kodanhas de Judô do Brasil.

A sessão de treinamento
A execução do planejamento ou da periodização do treinamento ocorre nas unidades de treinamento. Para o direcionamento dessas sessões é importante que os professores/treinadores/preparadores físicos considerem uma série de fatores. No texto em anexo (“Organização e sistematização da sessão de treinamento em programas de lutas, artes marciais e modalidades esportivas de combate: considerações centradas em aspectos fisiológicos”, escrito por mim e pelo Prof. Dr. Fabrício Boscolo Del Vecchio, http://www.sendspace.com/file/bd2xkc) são abordados os diferentes aspectos a serem considerados na organização da sessão de treinamento. Embora a decisão de como conduzir a sessão seja prerrogativa do profissional, tentamos, neste texto, apresentar as principais produções acadêmicas sobre como sistematizá-la. Assim, nesse material são encontradas considerações sobre (a) os princípios fisiológicos do aquecimento e suas aplicações, (b) a necessidade de alongar ou não antes de determinadas sessões, (c) como combinar o desenvolvimento de diferentes capacidades físicas em uma mesma sessão, dentre outros aspectos. Adicionalmente, recomendo a leitura das referências utilizadas na elaboração desse texto bastante sintético, para aprofundamento dos pontos nele discutidos.

Based on the spss software t+ of weight control on taekwondo athletes' body function influence research

Shenyang Sports University, Shenyang 110102, China 

Abstract

Weight control has become the ideal level of Taekwondo athletes participate in the competition the important method. According to the nine elite Taekwondo athletes as the research samples, research mainly by using the method of experiments, the experiments were carried out at six weeks, 1 times a week to sweat ion and the anaerobic capacity test and the four body fat content of the test, t test method for analysis of pre-race weight control on Athletes' body function influence. Results showed that, after a period of six weeks after the athlete's weight control, were highly significant changes in weight control; from the beginning of the third week, athlete's body weight and body fat content began to drop dramatically; through the test showed the percentage of body fat and lean body mass were decreased significantly; the anaerobic exercise capacity in athletes the weight control period was not changed significantly; from the beginning of the third week athletes sweat sodium and calcium ion concentration increased significantly, while carbon dioxide binding force is greatly reduced, until the end of sixth week weight control. By the appropriate increase in relaxation time and increase training of aerobic training proportion, can realize the athletes in weight control process to consume fat goal primarily, can provide excellent athletes to provide beneficial reference for weight control research.

ABSTRACT: We studied the effects of a high intensity and high frequency 3-month training program on muscle damage and neutrophil function in male judoists. The study included 15 male judoists who started intensive judo training program after a 6-month break. Creatine kinase (CK), neutrophil counts and reactive oxygen species (ROS) production capability as well as phagocytic activity (PA) of neutrophils were measured at 2 stages; entering university (pre-training) and after 3-month training (post-training). At both points, we investigated parameters three times: just before, immediately after and 24h after a 2-h practice session. Practice-mediated change in CK was lower at post-training than at pre-training. Neutrophil count significantly increased after 2-h practice but recovered 24 h later whereas it showed no subsequent and further increased at 24h post-practice. Although neutrophil ROS production capability and PA both decreased (breakdown) after practice session, ROS production capability increased and PA decreased (well-adapted) at the post-training. Long-term training strengthened muscular function and improved neutrophil reaction against practice-mediated stress.

A partir de hoje, colocarei semanalmente um artigo publicado por nosso grupo
