Another special consideration for the judo athlete is grip strength. In judo, if an athlete dominates the grip fighting, that athlete is usually in control of the match and has a higher chance of win- ning. Although there are tactical and strategic approaches to dominating the grips, overall grip strength does play a role. There are numerous exercises that focus on the grip, and the following list is only a partial list of what the judo ath- lete can use to improve grip strength and endurance: • Wrist curls. • Reverse wrist curls. • Barbell curls with pronated grip. • Pronated or supinated barbell or dumbbell curls with a “thick” bar.

    Health Benefits & Risks in the Young Judo Athlete USA Judo Sports Medicine Subcommittee Robert S. Nishime, M.D. The goal of USA Judo Sports Medicine is to promote and facilitate a healthy athletic lifestyle through safe judo participation. The health and safety of judo participants should always remain the number priority when advising or caring for our athletes. History and Philosophy Judo is one of the most participated sports worldwide, with practitioners spanning all age groups, gender lines, and ethnicities. Judo was originally derived from a truly “combat” oriented martial art known as jujitsu. Jujitsu was basically developed in medieval feudal Japan for battlefield ‘hand-to-hand/sword’ confrontations when a Samurai warrior lost his sword during combat. Therefore jujitsu became by necessity, a “dangerous” form of combat for survival and an adjunctive tool for victory during war. However, through the founder of judo, Professor Jigoro Kano, jujitsu made a profound transition from a dangerous, primarily combative art form. Professor Kano modified various styles of jujitsu into a “safe”, life enhancing martial art, which he called Judo or the “gentle way”, that is now an Olympic sport. He accomplished this in part by removing many of the striking, kicking, gouging, and joint locking techniques that were primarily intended to maim or injure an opponent. He retained and created techniques that could be practiced relatively safely and harmoniously between practitioners. He placed much emphasis on achieving “mutual benefit” when individuals train together. Professor Kano redirected the primary goals of training in his martial art from self-defense and survival to the development of mind, body, and character.

    The Origin & Historical Development of Silambam Fencing © 1988 by Dr. David Manuel Raj Contact: [email protected]; cell phone # 9884061557 or 9840020766 This research paper written in 1988 by Dr. David Manuel Raj, pictured below, was selected by the xxiv Seoul Olympic Scientific Congress (South Korea) and scheduled to be read on September 10, 1988 at one of the seminar halls at the Danhook University Campus in Seoul, South Korea. The Origin & Historical Development of Silambam Fencing: An Ancient Self- Defense Sport of India INTRODUCTION Etymologically Silambam is an onomatopoeic term for the swishing sound produced when an elastic cane bamboo, uniform in cross section and of a length which is a little less than that of the performer, is brandished with power and hit against another in the process of dueling (1). The purpose of this study was to trace the origin and the historical development of Silambam Fencing, a Dravidian Martial Sport of Tamil civilization, India from pre- historic time to the 20th Century A. D. METHOD This study was undertaken mainly by Library Research Method. HISTORY OF SILAMBAM FENCING BEFORE CHRIST According to Rapson, E. J. (2) several millennia before the Christian Era, the greater part of India was inhabited by Dravidians. Rajagopalan, K. (3) writes: Stick fight (Silambam Fencing) of Dravidians using cane bamboos is predominantly a prehistoric method of defense and attack. Paleolithic and Neolithic man found it quite handy in South India as a weapon for defense and attack against animal and human foes. Iyengar, S. (4) records: Single stick (wand of male bamboo) fencing is prevalent still in South India right from the Stone Age.

In preparing young wrestlers (16-17 years of age) the design often follows a relatively well-developed system of training for adult masters of sport. In general, the youthful body is characterized by a high intensity cardio-respiratory and blood systems during physical stress. So far, no data on the impact of intense competitive activity on the dynamics of individual aspects of preparedness of young wrestlers is available. Our objective was to study the impact of competitive activity on the functional training state in young wrestlers. Keywords: Competitions, Rules, Female Wrestling, Factor Analysis, Technique Wrestlers, training, weight management. INTRODUCTION Wrestling is unique among athletics. It is considered to be one of the most physically demanding sports among high school and college athletics. Wrestling was one of the most favored events in the Olympic Games in Ancient Greece. The first organized national wrestling tournament took place in New York City in 1888. From the Athens Games in 1896, until today, the wrestling events are also an important part of the modern Olympic Games. The International Federation of Associated Wrestling Styles (FILA) originated in 1912 in Antwerp, Belgium. The 1st NCAA Wrestling Championships were also held in 1912, in Ames, Iowa. USA Wrestling, located in Colorado Springs, Colorado, became the national governing body of amateur wrestling in 1983.

Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (November 2011) Martial arts are extensive systems of codified practices and traditions of combat, practiced for a variety of reasons, including self-defense, competition, physical health and fitness, as well as mental and spiritual development. The term martial art has become heavily associated with the fighting arts of eastern Asia, but was originally used in regard to the combat systems of Europe as early as the 1550s. An English fencing manual of 1639 used the term in reference specifically to the "Science and Art" of swordplay. The term is ultimately derived from Latin, martial arts being the "Arts of Mars," the Roman god of war.[1] Some martial arts are considered 'traditional' and tied to an ethnic, cultural or religious background, while others are modern systems developed either by a founder or an association.

It was revealed that the main criterion determining the success of combat sambo wrestlers in the competitive activity will be the level of their special training. Moreover, this training includes special endurance of athletes, active dynamics of competitive contests and the speed of recovery of fighters after intense training and competitive loads. Besides, to increase the level of special endurance combat sambo wrestlers significantly it was suggested to include in the training process of combat athletes the method of intensive functional training - crossfit. In a year of studies the tests on the evaluation of the level of recovery of combat athletes after a specific load showed that the athletes using the training method - crossfit in their training sessions demonstrated significantly (P <0.05) the best recovery time after the load than the wrestlers who did not use this technique.

  • How to Enhance Effectiveness of Direct Attack Judo Throws
    Attilio Sacripanti How to enhance effectiveness of Direct Attack Judo throws “Dr. Kano’s dream : Judo rotational application” Abstract In this paper it is performed an appraisal of the Olympic Sport “Judo” effectiveness in the optics of Biomechanics, that is the Dr Kano’s dream the rotational application of judo. Kano wasn’t able to develop his dream due to his premature death, but the biomechanical analysis is able to broaden the narrow translational vision of judo that is transmitted us by Kano’s disciples. Really speaking some learned followers of Dr. Kano like Kiuzo Mifune in Japan and Koizumi in England already had some rotational ideas, but few people appreciated their words. To broaden the classical view biomechanics will use a very special field f experimentation. This field of experimentation is obviously the high level competition in which most of these rotational application can be found applied more or less instinctively by high level Athletes. Considering the two biomechanical tools that are the physical basis of judo throws it is possible to obtain such results from the analysis of high competition application: Lever Techniques are enhanced in their effectiveness in three ways : 1. The rotational movements, strictly connected to the Lever techniques mechanics achieving victory (Ippon) in competition, can be extended to the unbalance phase (Kuzushi) 2. The rotational movements can be applied in a totally new way putting away even the unbalance that is basic in the Lever techniques. 3. The Lever tool can be hybridized with the application of a Couple to lower the energy consumption and to overcome some strong defensive resistance.

  • Techniques Frequently Used During London Olympic Judo Tournaments: a Biomechanical Approach
    Techniques frequently used during London Olympic judo tournaments: A biomechanical approach S. Sterkowicz,1 A. Sacripanti2, K. Sterkowicz – Przybycien3 1 Department of Theory of Sport and Kinesiology, Institute of Sport, University School of Physical Education, Kraków, Poland 2 Chair of Biomechanics of Sports, FIJLKAM, ENEA, University of Rome “Tor Vergata”, Italy 3 Department of Gymnastics, Institute of Sport, University School of Physical Education, Kraków, Poland Abstract Feedback between training and competition should be considered in athletic training. The aim of the study was contemporary coaching tendencies in women’s and men’s judo with particular focus on a biomechanical classification of throws and grappling actions. 359 throws and 77 grappling techniques scored by male and female athletes in Olympic Judo Tournaments (London 2012) have been analyzed. Independence of traits (gender and weight category by technique classes) was verified via c2 test. Comparison between frequency of each subsequent technique class and rest/inconclusive counts was made in 2×2 contingency tables. The significance level was set at p£0.05. Throwing technique frequencies grouped in the seven biomechanical classes were dependent on gender. A significant difference was found between frequencies of variable arm of physical lever technique scored by males (27.09%) and females (16.67%) as compared to the rest/inconclusively techniques counts. Significant differences between men who competed in extra lightweight and heavy weight concerned the frequency of the techniques used with maximum arm or variable arm of physical lever and a couple of forces applied by trunk and legs. In females, a tendency to higher frequency of techniques that used couple of forces applied by arm or arms and leg was observed in extra lightweight compared to the heavy weight.

  • Wrestling Injuries
    SPORTS TIP WRESTLING INJURIES restling, one of the world’s oldest sports, is offered at various levels of competition, including the Olympics, the American Athletic Union, the U.S. W Wrestling Federation, and high school and college-sponsored tournaments. It’s a sport for all sizes of people, and both male and female participants compete, even at the Olympic level. Competition rules require that athletes be paired against each other according to their weight class. Some competitions require that contestants be matched by age, experience, and/or gender. This not only allows more people to participate, but also decreases the risk for injury. Nevertheless, injuries do occur, particularly in the knee, shoulder, skin, and head. What are the most common wrestling injuries? The injuries include concussions, scrapes, bruises, tongue cuts, and cauliflower ear. However, knee and shoulder injuries occur with more severity than all other injuries and are responsible for the most lost time, surgeries, and treatments. Head and Face Cauliflower ears are caused by severe bruising of the ear structure. The resulting injury may need to be drained and the ear wrapped in a casting material to retain ear shape once the swelling has subsided. Although difficult to avoid, wearing headgear is the best defense against this potentially disfiguring injury. Wearing headgear with a frontal pad can also minimize the impact of the forehead and help prevent concussions. In addition to preventing severe tongue and tooth injury, a mouthguard can help prevent concussion, as well. Prepatella Bursitis Prepatella bursitis is the inflammation of the sac (bursa) located in front of the kneecap (patella).
