influence of linear and undulating strength periodization on physical fitness physiological and performance responses to simulated Judo matches
Journal of Strength and Conditioning Research, 2015Co-Authors: Emerson Franchini, Michel Calmet, Marcus F. Agostinho, Braulio Henrique Magnani Branco, Robin CandauAbstract:To determine the most effective strength periodization model is important to improve Judo athletes' performance. Thus, the aim of this study was to compare the effects of linear and daily undulating periodized resistance training on anthropometrical, strength, and Judo-specific performance. For this, 13 adult male Judo athletes (LP = 6 and DUP = 7) completed a 8-week training program concomitantly to a typical Judo training program. Athletes were submitted to a physical fitness test battery, before and after 8 weeks of training, consisting of: (a) maximal strength evaluation: bench press, squat, and row exercises 1 repetition maximum (1RM) tests, and handgrip maximal isometric strength; (b) power evaluation: standing long jump test; (c) strength endurance evaluation: dynamic and isometric chin-up tests gripping the Judogi; (d) anthropometry measurements: body mass, height, skinfold thickness and circumferences; (e) Judo-specific fitness: performance during the Special Judo Fitness Test (SJFT); (f) match simulation: three 5-minute Judo match simulations separated by 15-minute passive recovery. Eight weeks of linear and undulating strength training protocols induced similar significant (P ≤ 0.05) decreases in skinfold thicknesses (-6.5%) and increases in flexed arm (2.0%) and forearm (1.8%) circumferences, maximal isometric handgrip strength (4.6% and 6.1% for right and left hands, respectively), isometric strength endurance chin-up performance gripping the Judogi (18.9%), maximal dynamic strength for row (11.5%), bench press (11.6%) and squat exercises (7.1%), total weight lifted at 70% 1RM for bench press (15.1%) and squat (9.6%) exercises, number of throws during sets B (3.1%) and C (9.5%) of the SJFT (resulting in increased total number of throws, 5.5%), and decreased index in this test, -4.2%). However, no changes were observed in the physiological, rating of perceived exertion, or technical actions during 3 match simulations. Thus, it seems that the short-term adaptations were not transferable to the match condition.

The physiology of Judo-specific training modalities.
Journal of strength and conditioning research, 2014Co-Authors: Emerson Franchini, Ciro José Brito, David H. Fukuda, Guilherme Giannini ArtioliAbstract:Understanding the physiological response to the most common Judo training modalities may help to improve the prescription and monitoring of training programs. This review is based on search results using the following terms: "Judo," "Judo and training," "Judo and physiology," "Judo and specific exercises," and "Judo and combat practice." Uchi-komi (repetitive technical training) is a specific Judo exercise that can be used to improve aerobic and anaerobic fitness. Effort to pause ratio, total session duration, number and duration of individual sets, and the type of technique can be manipulated to emphasize specific components of metabolism. "Nage-komi" (repetitive throwing training) can also be used to improve aerobic and anaerobic fitness, depending on the format of the training session. "Randori" (combat or fight practice; sparring) is the training modality most closely related to actual Judo matches. Despite the similarities, the physiological demands of randori practice are not as high as observed during real competitive matches. Heart rate has not shown to be an accurate measure of training intensity during any of the previously mentioned Judo training modalities. High-volume, high-intensity training programs often lead Judo athletes to experience overtraining-related symptoms, with immunosuppression being one of the most common. In conclusion, Judo training and Judo-specific exercise should be manipulated to maximize training response and competitive performance.

Conclusions: Long term training has a minimal effect on anthropometry. Judo athletes of similar age when submitted to the same training type tend to show equal performance in the game and fitness levels after certain years of training. We also confirm existence of negative correlation between body fat and performance.

Physical fitness predicts technical-tactical and time-motion profile in simulated Judo and Brazilian Jiu-Jitsu matches
PeerJ, 2018Co-Authors: Victor Silveira Coswig, Paulo Gentil, João Carlos Alves Bueno, Bruno Follmer, Vitor Alves Marques, Fabrício Boscolo Del VecchioAbstract:Background Among combat sports, Judo and Brazilian Jiu-Jitsu (BJJ) present elevated physical fitness demands from the high-intensity intermittent efforts. However, information regarding how metabolic and neuromuscular physical fitness is associated with technical-tactical performance in Judo and BJJ fights is not available. This study aimed to relate indicators of physical fitness with combat performance variables in Judo and BJJ. Methods The sample consisted of Judo (n = 16) and BJJ (n = 24) male athletes. At the first meeting, the physical tests were applied and, in the second, simulated fights were performed for later notational analysis. Results The main findings indicate: (i) high reproducibility of the proposed instrument and protocol used for notational analysis in a mobile device; (ii) differences in the technical-tactical and time-motion patterns between modalities; (iii) performance-related variables are different in Judo and BJJ; and (iv) regression models based on metabolic fitness variables may account for up to 53% of the variances in technical-tactical and/or time-motion variables in Judo and up to 31% in BJJ, whereas neuromuscular fitness models can reach values up to 44 and 73% of prediction in Judo and BJJ, respectively. When all components are combined, they can explain up to 90% of high intensity actions in Judo. Discussion In conclusion, performance prediction models in simulated combat indicate that anaerobic, aerobic and neuromuscular fitness variables contribute to explain time-motion variables associated with high intensity and technical-tactical variables in Judo and BJJ fights.

Injuries in Judo: a systematic literature review including suggestions for prevention
British journal of sports medicine, 2013Co-Authors: Elena Pocecco, Fabrício Boscolo Del Vecchio, Gerhard Ruedl, Nemanja Stanković, Stanislaw Sterkowicz, Carlos Gutiérrez-garcía, Romain Rousseau, M. Wolf, Martin Kopp, Bianca MiarkaAbstract:Background There is limited knowledge on epidemiological injury data in Judo. Objective To systematically review scientific literature on the frequency and characteristics of injuries in Judo. Methods The available literature up to June 2013 was searched for prospective as well as retrospective studies on injuries in Judo. Data extraction and presentation focused on the incidence rate, injury risk, types, location and causes of injuries. Results During the Olympic Games in 2008 and 2012, an average injury risk of about 11–12% has been observed. Sprains, strains and contusions, usually of the knee, shoulder and fingers, were the most frequently reported injuries, whereas being thrown was the most common injury mechanism. Severe injuries were quite rare and usually affected the brain and spine, whereas chronic injuries typically affected the finger joints, lower back and ears. The most common types of injuries in young Judo athletes were contusions/abrasions, fractures and sprains/strains. Sex-differences data on Judo injuries were mostly inconsistent. Some studies suggested a relationship between nutrition, hydration and/or weight cycling and Judo injuries. Also, psychological factors may increase the risk of Judo injuries. Conclusions The present review provides the latest knowledge on the frequency and characteristics of injuries in Judo. Comprehensive knowledge about the risk of injury during sport activity and related risk factors represents an essential basis to develop effective strategies for injury prevention. Thus, the introduction of an ongoing injury surveillance system in Judo is of utmost importance.

Physiological Profiles of Elite Judo Athletes
Sports medicine (Auckland N.Z.), 2011Co-Authors: Emerson Franchini, Fabrício Boscolo Del Vecchio, Karin Ayumi Matsushigue, Guilherme Giannini ArtioliAbstract:To be successful in international competitions, Judo athletes must achieve an excellent level of physical fitness and physical condition during training. This article reviews the physiological profiles of elite Judo athletes from different sex, age and weight categories. Body fat is generally low for these athletes, except for the heavyweight competitors. In general, elite Judo athletes presented higher upper body anaerobic power and capacity than non-elite athletes. Lower body dynamic strength seems to provide a distinction between elite and recreational Judo players, but not high-level Judo players competing for a spot on national teams. Even maximal isometric strength is not a discriminant variable among Judo players. However, more studies focusing on isometric strength endurance are warranted. Although aerobic power and capacity are considered relevant to Judo performance, the available data do not present differences among Judo athletes from different competitive levels. Typical maximal oxygen uptake values are around 50-55 mL/kg/min for male and 40-45 mL/kg/min for female Judo athletes. As for other variables, heavyweight competitors presented lower aerobic power values. The typical differences commonly observed between males and females in the general population are also seen in Judo athletes when analysing anaerobic power and capacity, aerobic power, and maximal strength and power. However, further research is needed concerning the differences among the seven weight categories in which Judo athletes compete.

endurance in Judogi grip strength tests comparison between elite and non elite Judo players
Archives of Budo, 2011Co-Authors: Emerson Franchini, Bianca Miarka, Luciano Matheus, Fabrício Boscolo Del VecchioAbstract:Background The ability to develop a strong grip and maintain it during a Judo match has become an important element for Judo athletes. Therefore, the purpose of this investigation was to examine differences between measurements of maximal isometric time on Judogi pull-up, and number of repetitions during dynamic Judogi pull-up. Material/Methods: The sample was composed by two groups: 16 high-level Judo athletes from the male Brazilian National Team and 12 male state-level Judo athletes, with at least one athlete per weight category. The tests were compared through analysis of co-variance (body mass as co-variable), followed by a post-hoc test (Scheffe). Significance level was set at 5%. Results: No difference was found in the isometric test: Brazilian Team: 35±18s; Regional: 39±14s. However, the Brazilian Team performed a high number of repetitions (12±5 rep) compared to regional group (9±4 rep) during the dynamic grip strength endurance test. Conclusions: Thus, dynamic grip strength endurance seems to be a discriminating variable between Judo athletes, probably because Judo combat involves many elbow extensions and flexions in order to avoid the opponent’s grip and to subdue them.
