Resumo sobre vibração e terapia magnética em atletas de judô

Vopr Kurortol Fizioter Lech Fiz Kult. 2010 Sep-Oct;(5):24-7.

[The influence of vibration training in combination with general magnetotherapy on dynamics of performance efficiency in athletes].
Abstract

The objective of this study was to evaluate effects of a combined treatment including vibrostimulation and magnetotherapy on the working capacity of athletes. Participants of the study were 8 male judo wrestlers. It was shown that implementation of a specialized training program comprising seances of vibration loading and general magnetotherapy 40 and 60 min in duration respectively during 3 consecutive days produced marked beneficial effect on the hormonal status of the athletes. Specifically, the three-day long treatment resulted in a significant increase of blood cortisol and testosterone levels considered to be an objective sign of improved performance parameters in athletes engaged in strength and speed sports. The optimal length of vibration training during 3 days of specialized training is estimated at 20 to 40 minutes supplemented by general magnetotherapy for 60 minutes.

Variation in peroxisome proliferator activated receptor gene in elite combat athletes

Authors: Pawel Cieszczyka; Marek Sawczukb; Agnieszka Maciejewskab; Krzysztof Ficekc; Jerzy Eidera
Abstract
Peroxisome proliferator activated receptor (PPAR) is a main regulator of energy metabolism, as it regulates the expression of genes encoding several key muscle enzymes involved in fatty acid oxidation. Importantly for power sports, it may affect pathways of glucose metabolism, which can be critical in power-based sports. The aim of this study was to analyse the distribution of the PPAR gene polymorphisms in mixed power/endurance athletes. The study was carried out on elite combat athletes and sedentary individuals, in an attempt to determine possible relationships between genotype and physical performance. We tested 60 male elite Polish combat athletes. Control samples came from 181 unrelated sedentary volunteers. The G/C polymorphic site in PPAR intron 7 was scanned using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) protocol with TaqI enzyme. Differences in the distribution frequency of this polymorphism were assessed by chi-square analysis. The results revealed that frequencies of the PPAR GG genotype (73.33% vs. 54.70%; P=0.04) and G allele (82.50% vs. 70.17%; P=0.01) were significantly higher in the elite combat athletes compared with sedentary controls. The results confirm the significance of the PPAR gene as a useful genetic marker in combat athletes. However, these results should be supported with more experimental data on PPAR polymorphisms with larger groups of elite athletes.

Patterns of weight loss and supplement consumption of male wrestlers in Tehran.
Kordi R, Ziaee V, Rostami M, Wallace WA.
ABSTRACT:
BACKGROUND: To evaluate the weight loss behavior of male wrestlers in Tehran.
METHODS: This study was a population-based cross sectional survey. Subjects were 436 wrestlers randomly selected from the wrestling clubs in Tehran employing cluster sample setting method. Subjects were interviewed based on a designed questionnaire. Body fat levels were measured based on skin fold measurements.
RESULTS: Weight loss methods practiced by 62% of all subjects during the previous year employing rapid ([less than or equal to]7days before the matches) and gradual (>7 days before the matches) weight reduction methods (73% and 34% of wrestlers who reduced their weight respectively). In addition, opinions on weight reduction, the methods of weight loss used, and the side effects of the weight loss practices as well as consumption of supplements among the subjects were reported in this study. The mean percentage of body fat of subjects was 15.9%.
CONCLUSIONS: Rapid weight loss for matches and the use of unsafe methods of weight reduction such as fasting, and fluid reduction methods as well as acute side effects of weight loss were prevalent among wrestlers in Tehran. Some preventive measures including education and new rules such as scheduling weigh-ins immediately prior to the competitions and mat-side weigh-in are needed to prevent these unhealthy practices. The weight loss behaviors of these wrestlers should be changed from using dehydration methods to using gradual methods of weight loss.

Electromechanical delay in ballistic movement of superior limb: comparison between karate athletes and nonathletes.
Rodrigues Ferreira MA, Vences Brito A.
Sports Sciences School of Rio Maior, Polytechnic Institute of Santarém. marioarf@gmail.com
Abstract

The aim of the study was to analyze electromechanical delay in a ballistic movement of the superior limb. 10 male karate athletes and 9 nonathletes (without karate experience) performed a motor skill as fast and powerfully as possible, with impact on a makiwara (karate training instrument). For each participant, 10 choku-zuki performances were analyzed. Kinematics and surface electromyographic (EMG) activity of the anterior and posterior portions of deltoid, pectoralis major, latissimus dorsi, triceps brachii, and biceps brachii were recorded. Athletes had significantly shorter delay in arm flexion agonist muscles and significantly higher delay in arm flexion antagonist muscles and in forearm extension agonists. Results suggest that enhanced performance in athletes was mainly due to motor learning.

Celulares podem causar interferência nos coletes do TKD

Dica da Paula Avakian
Fonte: mastaekwondo.com
Celulares alterarían el funcionamiento de Petos Oficiales


Según publicó la Federación de Taekwondo de Puerto Rico en su artículo “Tecnología vs Tecnología” los Petos LaJust mostraron comportamiento anormal durante el Selectivo Nacional Panamericano.
Al parecer los Petos Electrónicos LaJust que se utilizarán en el próximo Mundial Absoluto de Corea y tienen la posibilidad de ser usados en los Juegos Olímpicos de Londres 2012, tendrían importantes problemas por interferencias electromagnéticas.
Según un ingeniero especialista en telecomunicaciones, los teléfonos móviles 3G operan en una frecuencia de 1.8Ghz y los 4G en una frecuencia de 4.0Ghz. Al parecer el sistema de radio de LaJusto bien no está operando en una frecuencia óptima o bien no tiene filtros para bloquear cualquier tipo de interferencia. En cualquier caso, este fallo de comunicación puede convertirse en un grave problema durante cualquier evento.
Tony Acevedo, Gerente General de la Federación de Taekwondo de Puerto Rico, escribía “Todo parecía que iba a ser un evento de corta duración ya que al solo disputarse los 4 pesos combinados, solo había 16 combates programados para el día. Sorpresivamente de momento, los Petos Electrónicos comenzaron a mostrar comportamiento anormal. Estos se negaban a registrar contacto durante la prueba inicial que hacen los competidores, obligando a los técnicos a detener la acción mientras cambiaban constantemente el peto y los sensores. Para mayor confusión, se podía notar que la falla ocurría primero en todos los petos rojos y más adelante en todos los petos azules. Esto hizo sospechar que la falla no era en los petos sino debido a alguna anomalía exterior”. Publicaba el sitio oficial de Puerto Rico.
“Finalmente después de varias horas de retraso y eliminación de posibles causas, el Maestro Hong Ki Kim, Asesor de la FTPR, descubrió que el problema surgía de la conglomeración cercana de teléfonos celulares con la moderna tecnología 4G y 3G, radios de comunicación que se estaban utilizando en el área por efectivos de la Guardia Nacional y micrófonos inalámbricos. Una vez se apagaron los micrófonos y radios de comunicación y se le pidió al público que se mantuviera en el área de las gradas alejados de la mesa técnica, el problema desapareció y el evento prosiguió sin más interrupciones hasta su conclusión.”Concluía Acevedo en su artículo.
Coincidiendo con lo acontecido en Puerto Rico, trascendió que en el “5º Commonwealth Taekwondo Championships” que se celebró en Chennai, India, el pasado 28-31 de enero, donde también se utilizaron los Petos LaJust, al parecer estos problemas también acontecieron.
En las finales, las cuales fueron retransmitidas en directo por la televisión de la India, tuvieron que cambiar los petos en cada uno de los combates porque por alguna razón no funcionaban, de hecho fue llamativo el caso del combate de Escocia contra Trinidad y Tobago (SCO vs TRI), en el tercer round el competidor de TRI le produjo un knock out con un Tuitchagui, pero el árbitro central no se dio cuenta que era un KO porque no hubo puntuación en el marcador y empezó a llamar al servicio médico. Posteriormente el Jefe de árbitros del evento Sr. Brian Tilley, ratificó el knock out ya que el movimiento no fue registrado por el sistema, como si nunca hubiera existido el golpe.
En la nota realizada recientemente con Jesús Tortosa donde nos explicaba los puntos tenidos en cuenta a la hora de testear un sistema de petos, no queda muy claro si también se están analizando posibles interferencias como las que citamos al comienzo.
Sin dudas no hay, ni debe haber, vuelta atrás en el uso de sistemas electrónicos de puntuación, pero tampoco existen dudas, que hay mucho para mejorar en el corto tiempo que nos separa de Londres 2012.

Abstract
Objective: To systematically summarize the evidence for the effects of martial arts on health and fitness, to show the strengths of different types of martial arts, and to get a more complete picture of the impacts of martial arts on health, and also to provide a basis for future research on martial arts as an exercise prescription in exercise therapy. Method: We searched for "martial arts" "health" and "random" in eight databases (n = 5432). Randomized controlled trials and controlled clinical trials on the health effects of martial arts were included in the study. Results: The final analysis included 28 papers (one general martial arts, one kung fu, sixteen tai chi, six judo, three karate, and one taekwondo). Among the disciplines of martial arts, tai chi was the most well-studied, followed by judo, karate, and taekwondo. Research topics varied widely, and included health, injuries, competition, morals and psychology, and herbal medicine. Most found positive effects on health. Tai chi is no-contact, low-impact, soft body and mindfulness exercise, which has been widely adopted by elderly people and proven to be a beneficial health promotion exercise. Research on judo, karate, and taekwondo mainly focused on improvements to athletes' competitive abilities, rather than on health effects. We did not find any published randomized controlled trials or controlled clinical trials on aikido, kendo, sumo, kyudo, qi gong, or other disciplines. Discussion and Conclusion: Since martial arts are widely practiced, their effects on physiology, morphology, immunology, and neurology should be further studied in order to help people to select the best discipline or style to accomplish their purposes. This necessitates categorizing and classifying the disciplines and styles according to their effects on different body systems and levels of contact, as well as standardizing evaluation criteria for martial arts. Martial arts as an exercise prescription can then move from an experience-based to an evidence-based treatment.

Effects of Basic Karate Exercises on Maximal Oxygen Uptake in Sedentary Collegiate Women

Author(s): Yoshimura Y (Yoshimura, Yoshitaka)2, Imamura H (Imamura, Hiroyuki)1
JOURNAL OF HEALTH SCIENCE Volume: 56 Issue: 6 Pages: 721-726 Published: DEC 2010
Abstract: The primary purpose of this study was to investigate the chronic effects of practicing 30 min of basic karate exercises (BKEs) for 10 weeks on maximal oxygen uptake VO2max) in sedentary collegiate women who had no previous karate experience. The secondary purpose of this study was to investigate physiological responses and intensities of BKEs to examine the intensity of exercise. Nine women practiced 30 min of BKEs, 4 days.week(-1), for 10 weeks. The six other women acted as controls. The 30 min of BKEs consisted of 9 min of stationary basics in a parallel stance (S-Basics I), 12 min of stationary basics in a front stance (S-Basics II), and 9 min of movement basics in the front stance (M-Basics). For S-Basics I, the mean percent of maximum VO-2 reserve (%VO2R) was much lower than the accepted threshold, while the mean percent of maximum heart rate reserve (%HRR) was slightly lower than the accepted threshold for increasing VO2max, i.e., 40% of VO2R or HRR. For S-Basics II, the mean VO2R was marginal, while the mean %HRR was above the accepted threshold for increasing VO2max. The mean %VO2R and % HRR for M-Basics were above the threshold for increasing VO2max. VO2max in both l.min(-1) and ml.kg(-1).min(-1) in the experimental group significantly increased at the end of the 10 weeks of training (from 1.80 +/- 0.30 to 2.00 +/- 0.34 l.min(-1) and 32.3 +/- 4.1 to 36.0 +/- 4.4 ml.kg(-1).min(-1), respectively), while neither value changed significantly in the control group. In conclusion, 30 min of BKEs can reach the minimal threshold level to increase cardiovascular fitness and can improve cardiovascular fitness in sedentary women.

'Now the African reigns supreme': The rise of African boxing on the Witwatersrand, 1924-1959.
Fleming T.

Columbus State University, GA.

Abstract

This essay explores the growth of boxing among the African populations on the Witwatersrand region of South Africa between 1924 and 1959. It details how the sport's jump in popularity with Africans paralleled migration to Johannesburg. Africans increasingly saw boxing as an activity and skill conducive with survival in this new environment, and thus the sport grew in popularity, stature, and skill-level amongst this emergent urban population. The essay further explores the various ways that the sport was disseminated and popularized during the era, thus detailing how the sport reached both the African masses and petit-bourgeois educated elite. As their presence in Johannesburg became more and more permanent, boxing came to encompass various meanings and ideals, such as notions of discipline, independence and civility, to these urban populations.
