In the following, we provide a description of the changes introduced, 20 which are also highlighted in the manuscript. 21 22 23 24 We would like to thank you and the Reviewers for the time and expertise devoted to 25 improving the quality of our manuscript. I trust that this revised version will be suitable for 26 27 publication in The Journal of Sports Medicine and Physical Fitness. 28 29 30 Best regards, 31 32 33 Chiarella Sforza 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 Page 2 of 31 1 2 3 # Reviewer 1 4 R1.1 Major corrections (main criticisms) 5 6 Here are several major concerns: (1) The participant performed a traditional Shotokan 7 8 karate – KATA which is a standardized sequence of karate movements. The some 9 parameters from CoM and knee were analyzed. Those parameters are critical factors to 10 11 KATA? It needs solid evidence-based support. 12 13 We would like to thank the Reviewer for his/her precious suggestions. 14 We thoroughly reconsidered the main passages of the Discussion and Introduction, as 15 16 marked in the text. As suggested, we added in the Introduction a paragraph containing 17 information about the critical factors for Kata performance, that on a biomechanical 18 19 perspective include also those mentioned by the Reviewer. These data are supported by 20 21 previously published studies. 22 23 24 R1.2 (2) Those parameters were analyzed from which karate movement of KATA? which 25 26 movement phase? 27 We agree that the data extraction flow was not clear and we thank the Reviewer for the 28 29 chance to clarify this point. We now added details about the computation of kinematic 30 31 data in the Procedures section. Moreover, we added in the Discussion some features 32 regarding relevant outcomes for knee kinematics in particular step of the sequence. 33 34 35 36 R1.3 (3) Kumite and Kata are two types of karate. The scoring requirements and critical 37 factors are very different between Kumite and Kata. However, some literatures on 38 39 Kumite also cited in the discussion. 40 41 The point raised by the Reviewer is correct. However, the studies we included 42 addressed both kata and kumite athletes (references #2 and #5) in order to highlight 43 44 the relevance of dynamic postural control during the execution karate techniques. In 45 such papers, the importance of the achievement of a adequate technique (also in terms 46 47 of biomechanical parameters) is addressed, and its role in the obtainment of a high-level 48 49 performance is discussed. 50 51 52 # Reviewer 2 53 54 Major corrections (main criticisms) 55 Page 3 of 31 1 R2.1 The usage of expressions as “reduced” or “decreased” (see detailed comments) are 2 3 inappropriate and should be replaced throughout. However, I feel some speculations on 4 practical consequences or specific recommendations would enhance the value for the 5 6 reader. All the areas where the manuscript needs further improvement have been 7 8 pointed in the specific comments. 9 We would like to thank the Reviewer for his/her precious suggestions. We thoroughly 10 11 checked the manuscript and clarified all the potentially misleading expressions. 12 13 As prompted by this suggestion, we also added some practical outcomes and 14 recommendations that could provide useful insights for the reader. 15 16 17 R2.2 Minor corrections (page, paragraph, line where the author must make the 18 19 corrections) 20 21 Page 2, Line 7: replace “study is” with “study was” 22 Fixed as suggested by the Reviewer. 23 24 25 26 R2.3 Page 2, Line 16: Please delete “traditional”. 27 This word was deleted as suggested by the Reviewer. 28 29 30 31 R2.4 Page 2, Line 16: Please delete “Shotokan” (doubling). 32 Thank you for noticing the typo. We deleted the doubling. 33 34 35 36 R2.5 Page 2, Line 20: replace “more” with “longer” 37 Corrected as suggested by the Reviewer. 38 39 40 41 R2.5 Page 2, Line 22: replace “decreased” with “lower” 42 Corrected as suggested by the Reviewer. 43 44 45 R2.6 Page 2, Line 27: replace “reduced” with “lower” 46 47 Corrected as suggested by the Reviewer. 48 49 50 R2.7 Page 3, Line 9: change “incoming” into “upcoming” 51 52 Changed as suggested by the Reviewer. 53 54 55 Page 4 of 31 1 R2.8 Page 3, Line 12: change “involving a sequence” into “involving sequences” 2 3 Changed as suggested by the Reviewer. 4 5 6 R2.9 Page 3, Lines 28-30: This is also true for the non-paralympic games, I guess. 7 8 The point raised by the Reviewer is correct. We focused only on the Paralympic Program 9 to highlight the lack of international recognition for top level competitions of para- 10 11 karate. However, if the Reviewer believes that adding a reference to able-bodied 12 13 competitions should clarify the context for the reader, we are open to add more details. 14 15 16 R2.10 Page 3, Line 53: change “Participants” into “Participant” 17 We made the change as suggested by the Reviewer. 18 19 20 21 R2.11 Page 4, Lines 14-16: What does “5/6” or “3/4” mean in this context? 22 The Paralympic karateka trained 5 to 6 times per week before and 3 to 4 times per week 23 24 after the operations. We agreed that there was a lack of clarity. We clarified this 25 26 sentence by replacing “/” with “to”. 27 28 29 R2.12 Page 4, Line 29: Which kata was performed? 30 31 As stated, the kata was the same of the previous study (reference #14) taken as a 32 comparison with able-bodied athletes. We intentionally didn’t report the entire 33 34 sequence of movements to avoid redundancy. However, if the Reviewer believes that 35 36 adding the description of the whole sequence of movement should be useful for the 37 reader, we are available to add the details of kata performed. 38 39 40 41 R2.13 Page 4, Line 37: What does “advancement” means? “in front”? “forwards”? 42 We acknowledge that passage was not as clear as we intended. We added “forward” 43 44 before “advancement” to clarify the direction of the movement. 45 46 47 R2.14 Page 5, Line 43: replace “reduced” with “lower” 48 49 Replaced as suggested by the Reviewer. 50 51 52 R2.15 Page 6, Line 29: replace “decreased” with “was lower” 53 54 Replaced as suggested by the Reviewer. 55 Page 5 of 31 1 2 3 R2.16 Page 7, Line 13: What does “decreasing” mean in this context? 4 Thanks for the question. We replaced “decreasing” with a more consistent expression to 5 6 highlight physical impairments negative effects. 7 8 9 R2.17 Page 9, Lines 19-21: Please correct citation #5. 10 11 Thanks for noticing the error. We corrected the citation adding the missing details. 12 13 14 R2.18 Figures 1 and 2: The resolution of the figures should be improved. Why did you 15 16 report the median instead of the mean with 95% confidence intervals? 17 We now exported the figures at higher resolution. 18 19 Thanks for noticing the typo. We replaced “median” with “mean”. 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 Page 6 of 31 1 Kinematic traits of an elite Paralympic karateka: a case study 2 3 4 Authors: Filippo BERTOZZI1#, Matteo ZAGO1,2#, Daniela CIPRANDI1, Christel GALVANI3, 5 6 Chiarella SFORZA1,4* 7 8 9 Authors affiliations: 1Department of Biomedical Sciences for Health, Università degli Studi di 10 2 11 Milano, Milan, Italy; Department of Electronics, Information and Bioengineering (DEIB), 12 Politecnico di Milano, Milan, Italy; 3Department of Psychology, Università Cattolica del Sacro 13 14 Cuore, Milan, Italy; 4Institute of Molecular Bioimaging and Physiology, National Research 15 16 Council, Segrate, Italy 17 #Dr Bertozzi and Dr Zago equally contributed to this study 18 19 20 *Corresponding author: 21 22 Prof. Chiarella Sforza, MD 23 24 Dipartimento di Scienze Biomediche per la Salute, Università degli Studi di Milano 25 Via Mangiagalli 31, 20133, Milan, Italy 26 27 [email protected] 28 29 30 Abstract word count: 215 31 32 Text-only word count: 1920 33 Number of figures and tables: 2 figures; 1 table 34 35 Number of references: 26 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 Page 7 of 31 1 ABSTRACT 2 3 Karate is a martial art that include striking, kicking and punching techniques, demanding and 4 requires high levels of functional abilities skills.

  • Paralympic Judo: Is There Evidence for Match Rigging Among Athletes with Disabilities?
    Annals of Applied Sport Science, vol. 5, no. 3, pp. 63-68, Autumn 2017 Original Article www.aassjournal.com www.AESAsport.com ISSN (Online): 2322 – 4479 Received: 08/03/2017 ISSN (Print): 2476–4981 Accepted: 12/10/2017 Paralympic Judo: Is there Evidence for Match Rigging among Athletes with Disabilities? 1 * 2 Wadim Strielkowski , Anatoly Shishkin 1Cambridge Judge Business School, University of Cambridge, Cambridge, United Kingdom. 2Plekhanov Russian University of Economics, Moscow, Russian Federation. ABSTRACT Objectives: This paper studies the existence or non-existence of match-fixing (or rigging) among judo wrestlers (judoka) with disabilities during the consecutive Paralympic Games from 1988 until 2016. Methods: In our analysis, we use the institutional framework that makes it easy understand and model the incentives of the wrestlers using the readily available data. Our data set consists of official judo matches that took place during the Paralympic Games from Seoul in 1988 to Rio in 2016. We analyze the distribution of wins across judokas, the medal count at the end of each medal tournaments. Results: Our results are quite similar across specifications. There is no significant evidence to prove that some Paralympic judokas tend to be victorious more often on average than it might be expected. Conclusions: We find no evidence can be found to document match rigging in Paralympic judo wrestling. Our analysis does not confirm the corruption story or rule out effort as the explanation. While the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents in some other sports with athletes winning a disproportionate share of the matches when they are on the margin, this does not seem to be the case of Paralympic judo.

    BLOC DE CONTINGUTS: JOCS I ESPORTS JOCS I ACTIVITATS DE LLUITA. CONTACTE I COOPERACIÓ JUDO 1.What is JUDO? Judo is a Japanese martial art. It was founded in 1882 by Jigoro Kano. Jigoro wanted to pick up the essence of the old jujitsu schools, along with other fighting arts practiced in Japan and merge them into one. Judo laid the foundations for the modern Japanese martial arts. Judo is one of the four main styles of amateur competitive struggle practiced today worldwide. Practitioners of this art are called judokas. Jidoro Kano summarizes the philosophy of Judo saying: The main condition of Nague- waza is projecting our opponents using the minimum of our strength, this principle applies to all aspects of our lives. Once on the ground can freeze or abandon the match with a choke or a dislocation. Judo is practiced in the dojo (place where one learns the way), and barefoot on a surface called tatami. The uniform of practicing Judo is called judogui, which consists of a jacket, open and without buttons, trousers and belt. The judogui is white and is made of a material resistant to traction. The belt has two functions, adjust the jacket body and identify its color according to the degree of knowledge that the student possesses. The different levels are higher in smaller: white, yellow, orange, green, blue and brown in the category of Kiu or student. DAN category or teachers are represented by the black belt, the first being its progression until the 10th. The highest degree awarded 10th Dan has been identified with a red belt.

  • A Brief History of Judo by Alex Mashadi
    A Brief History of Judo by Alex Mashadi Judo is a relatively new Japanese martial art developed in Japan in 1882 by Dr Kano Jigoro. Its aim is to either throw the opponent to the ground, immobilize or otherwise subdue the opponent, or force an opponent to submit by a strangle hold or arm lock. Kano Jigoro was born in 1860 into an affluent Japanese family. His grandfather was a self-made man, a sake brewer from central Japan. However, Kano's father was not the eldest son and therefore did not inherit the business. Instead, he became a Shinto priest and government official, with enough influence for his son to enter Tokyo Imperial University. Kano was a small, frail boy, who was often picked on by bullies. At the age of 17, he first started jujutsu but with little success. This was in part due to his difficulties finding a teacher who would take him on as a student. When he went to university to study literature at the age of 18, he continued his martial arts studies, eventually gaining a referral to Fukuda Hachinosuke (c.1828– c.1880), a teacher who stressed the importance of technique over formal exercise, which led to Kano’s belief in the importance of free practice (randori). A little more than a year after Kano joined Fukuda's school, Fukuda became ill and died. Kano then became a student in a number of other schools, where varying degrees of emphasis was put on the practice of pre-arranged forms (kata) or free practice.

  • W the HISTORY of JUDO W
    w THE HISTORY OF JUDO w Jigoro Kano 1860 -1938 Assistant Club Instructor Essay - History of Judo.doc David Scott Page 1 04/02/2014 Introduction Judo is essentially a martial art so, in order to fully appreciate a history of judo, we shall look at a brief background on martial arts first. The English term “martial arts” is derived from Latin for “arts of Mars” - Mars being the Roman God of war. While the term “martial arts” today is normally associated with the Asian fighting arts, for centuries martial systems have also existed in western culture. We can date martial arts such as archery and wrestling back to ancient Greece, and in Mesopatamia there is evidence (such as paintings and poems depicting systematic fighting) that martial arts training dates back to Babylonian times (3000BC). In the far east, development of the Oriental martial arts is somewhat obscure. It is generally accepted that the Oriental martial arts developed in ancient China, during the Xia Dynasty more than 4000 years ago. This was among monks who used weaponless fighting techniques to protect themselves. Rulers of the Orient attempted to keep unarmed combat techniques secret, but through commerce and migration, the martial arts spread from China throughout the east. Chronicles concerning martial arts dating back as far as 720 AD discuss Japanese wrestling and, since then, the martial arts have developed into a variety of systems that have lead to the modern martial arts that we see today. There are currently more than 1,000 different forms of martial arts scattered around the world.

  • Hello Everyone! My Name Is Stephen Cannell. I Work As a Coordinator For
    Judo Hello everyone! My name is Stephen Cannell. I work as a coordinator for international relations (CIR) in Toyohashi. Today I would like to talk about judo, a combat sport that will be at the Tokyo 2020 Olympics. Judo is a Japanese sport that dates back to 1882. It was created by Kano Jigoro, a jujutsu practitioner who wanted to improve on jujutsu. It quickly grew in popularity, and began to be taught in schools, the police, and the military. In the 1950s, it had grown to become popular around the world, and international tournaments began to take place. It officially became an Olympic sport at the 1964 Tokyo Olympics, and was added to the Paralympics in 1988. There are many martial arts, including Brazilian jiu-jitsu, Russian Sambo, etc. that were influenced by judo. There are two methods of attacking in competition judo: throws, known as nage-waza, and grapples, known as katame-waza. There are 100 different techniques that may be utilized in judo, however some techniques that are too dangerous are banned from international competition. The goal of nage-waza is to throw your opponent on their back to the floor. There are standing throws, and those in which you bring your opponent down with you. The goal of katame-waza is to put the opponent into a position from which they cannot attack back. The goal of both competitors in a judo match is to land an ippon, which is an immediate victory. In order to be awarded an ippon, the athlete must perform a nage-waza or katame- waza on their opponent while meeting a specific set of guidelines.
