ObjectivesTo report injury patterns associated with the training activities of elite male and female South Korean wrestling athletes preparing for the Olympic Games.MethodsFrom 2008 to 2017, we prospectively collected data on elite wrestling athletes at the Korea National Training Center. Athletes were assessed by two sports medicine doctors, and data were stratified according to sex, wrestling style, weight class, injury location and injury severity. Χ2tests were used to compare groups. Injury risk was expressed in relative ratios with 95% confidence intervals (RR, 95% CI).ResultsThere were 238 male and 75 female elite wrestlers. Training time totalled 382 800 hours. We recorded 1779 injuries in 313 athletes aged >18 years (annual average, 4.04 injuries/athlete); 59% of these were mild injuries. When all athletes were considered, most injuries occurred in the lower extremities (37.5%), followed by the upper extremities (27.4%), trunk (25.4%) and the head and neck area (9.7%). Weight class significantly influenced injury severity for both wrestling styles among male athletes (Greco-Roman, P=0.031; freestyle, P=0.028), as well as among female freestyle wrestling athletes (P=0.013). The relative ratio of injury incidence for the lightweight class compared with the heavyweight class was high for Greco-Roman style compared with freestyle (RR 1.13, 95% CI 1.03 to 1.27; P=0.011).ConclusionsAmong male and female South Korean elite wrestling athletes training for the Olympic Games, most injuries were mild and occurred in the lower extremities. Weight class influenced injury severity in both wrestling styles, and lightweight athletes had higher injury rates.

ObjectivesWe aimed to determine the injury patterns associated with training activities in elite South Korean taekwondo athletes training for the Olympic Games.MethodsWe collected data prospectively from 2007 to 2016 at the Korea National Training Center in Seoul, South Korea. A sports injury was defined as acute or chronic musculoskeletal signs and symptoms due to taekwondo activities during training sessions. Athletes were assessed by an on-site sports medicine specialist. The elite taekwondo athletes were stratified according to sex, weight class (flyweight, featherweight, welterweight and heavyweight), injury location (body region and site) and injury severity (mild or level I, requiring treatment for 1–3 days; moderate or level II, requiring treatment for 4–7 days; or severe or level III, requiring treatment for ≥8 days).ResultsAthlete exposure was 56 160 training sessions that took 249 600 hours. 1466 injuries were recorded in 283 athletes, with an average of 4.6 injuries per athlete annually. Of these, more than half (56%) were mild injuries, with most injuries occurring in the lower extremities (65.5%), followed by injuries to the trunk (16%), upper extremities (14%) and head and neck area (4%). Among these athletes, women had higher injury rates in the featherweight and welterweight categories (P≤0.0001), but there were no sex differences in other weight categories. In general, female athletes and male athletes experienced a comparable risk of injury (relative ratio: 1.55; 95% CI 0.89 to 2.68).ConclusionIn elite South Korean taekwondo athletes, most injuries occur in the lower extremities and were graded as minor. Injury severity depended on weight class.

На сегодняшний день имеет место противоречие между большим объемом эмпирического и статистического материала по достижениям чувашских спортсменов в крупнейших международных соревнованиях и недостаточно глубоким их анализом, лежащим в основе выявления закономерностей и перспектив развития спорта в республике. Целью исследования является выявление динамики и закономерностей участия спортсменов Чувашской Республики в составе сборной команды страны на Олимпийских играх 1952-2016 гг. Методы исследования: теоретический анализ исторической и справочной литературы по теме исследования, анализ документальных материалов, методы математической статистики. В советский период наибольшее число участников Олимпийских игр среди спортсменов Чувашской Республики (по 4 человека) приходится на игры 1972 и 1976 гг. Самыми успешными можно признать выступления спортсменов Чувашской Республики на Олимпийских играх 1968, 1976 и 1980 гг. Наиболее высокое среднее место приходится на бокс, фехтование, командную велогонку, борьбу классическую. В постсоветский период представительство спортсменов Чувашской Республики в составе Олимпийской сборной России заметно увеличилось и составило по 10 человек на играх в 2000 и 2004 гг., 9 человек на играх в 2008 г. Можно выделить 20-летний период успешного выступления спортсменов Чувашской Республики на Олимпийских играх - с 1992 по 2012 гг. Наиболее высокое среднее место приходится на спортивную гимнастику, бег 3000 м с препятствиями. Today, there is a contradiction between a large volume of empirical and statistical material on the achievements of athletes of the Chuvash Republic in major international competitions and insufficient analysis, which is the basis for identifying the regularities and prospects for the development of sports in the republic. The aim of the study is to identify the dynamics and patterns of participation of athletes of the Chuvash Republic in the national team at the Olympic Games of 1952-2016. The research methods are theoretical analysis of historical and reference literature on the research topic, analysis of documentary materials, methods of mathematical statistics. In the Soviet period, the largest number of participants in the Olympic Games among athletes of the Chuvash Republic (4 people) was in the 1972 and 1976 Games. The performances of the Chuvash athletes at the Olympic Games of 1968, 1976 and 1980 can be considered the most successful. The most striking results were achieved in boxing, fencing, team cycling, and Greco-Roman wrestling. In the post-Soviet period, the representation of athletes of the Chuvash Republic in the Russian Olympic team has noticeably increased and amounted to 10 people at the games in 2000 and 2004, 9 people - at the games in 2008. A 20-year period from 1992 to 2012 can be considered most successful. The greatest results were achieved in gymnastics and steeplechase.

The United World Wrestling carried out the implementation of seeding athletes for the first time at the 2016 Rio Olympic Games. For this reason, the aim of the current study was to calculate the probability of winning a medal and becoming an Olympic Champion at the 2016 Rio Olympic Games of seeded wrestlers using the Bayesian theorem. The data were obtained from the results book of the Rio Olympic Games. The obtained data were analyzed Bayesian theorem. According to the results, the probabilities of being an Olympic Champion of first seeded wrestlers were 67.0%, 81.0% and 62.0% for males Greco-Roman, freestyle and female freestyle, respectively. As a result, being a seeded athlete had a great advantage to become an Olympic Champion in the wrestling competitions of the Rio Olympic Games. As the Olympic Games are held every four years, the medals in the Grand Prix tournaments, continental, and World Championships must be scored according to difficulty grade and medal colour, and the Olympic ranking should be established for each weight category. Furthermore, it would provide more competitive, challenging and enjoyable Olympic Games for wrestling and spectators.

ObjectivesThe Professional Rugby Injury Surveillance Project is the largest and longest running rugby union injury surveillance project globally and focuses on the highest level of rugby in England.MethodsWe examined match injuries in professional men’s rugby over the period 2002/2003 to 2018/2019 and described trends in injuries over this time.ResultsOver the period 2002/2003–2018/2019, 10 851 injuries occurred in 1 24 952 hours of match play, equating to a mean of 57 injuries per club per season and one injury per team per match. The mean incidence, severity (days absence) and burden (days absence/1000 hours) of injury were 87/1000 hours (95% CI 82 to 92), 25 days (95% CI 22 to 28) and 2178 days/1000 hours (95% CI 1872 to 2484), respectively. The tackle accounted for 43% injuries with running the second most common activity during injury (12%). The most common injury location was the head/face with an incidence of 11.3/1000 hours, while the location with the highest overall burden was the knee (11.1 days/1000 hours). Long-term trends demonstrated stable injury incidence and proportion of injured players, but an increase in the mean and median severity of injuries. Concussion incidence, severity and burden increased from the 2009/2010 season onwards and from 2011 to 2019 concussion was the most common injury.ConclusionThe rise in overall injury severity and concussion incidence are the most significant findings from this work and demonstrate the need for continued efforts to reduce concussion risk as well as a greater understanding of changes in injury severity over time.

Context: Injuries are a major adverse event in a soccer player's career. Reducing injury incidence requires a thorough knowledge of the epidemiology of soccer injuries. Objective: To investigate the incidence and characteristics of injuries in the Dutch premier soccer league. Design: Cohort study. Setting: The Dutch premier soccer league. Patients or Other Participants: During the 2009–2010 soccer season, a total of 217 professional soccer players from 8 teams were prospectively followed. Main Outcome Measure(s): The medical staff recorded time-loss injuries, including information on injuries (ie, type, body part, duration) and exposure data for training sessions and matches. Results: A total of 286 injuries were recorded, affecting 62.7% of the players. The overall injury incidence was 6.2 injuries per 1000 player-hours, 2.8 in training sessions and 32.8 in matches. Most of the recorded injuries were acute (68.5%). Eight percent of the injuries were classified as recurrent. Injuries were most likely to be located in the lower extremities (82.9%). Injury time loss ranged from 1 to 752 days, with a median of 8 days. Knee injuries had the greatest consequences in terms of days of absence from soccer play (on average, 45 days). The most common diagnosis was muscle/tendon injury of the lower extremities (32.9%). Conclusions: Injury risk in the Dutch premier soccer league is high, especially during matches. Preventive measures should focus on the most common diagnoses, namely, muscle/tendon injuries of the lower extremities.

2004 is an Olympic year, so it is worth directing some attention to the ‘inventors’ of the Olympic Games, the ancient Greeks who, in the early eighth century BC, according to at least one tradition, founded the Olympic Games in the precinct of Zeus, an area on the Peloponnese not far from the later city of Elis. The ‘inventor’ of the new Olympic Games in 1896, the French Baron, Pierre de Coubertin, drew at least part of his inspiration from the ancient predecessors. What was the status of the ancient Olympics in the world of sports in the Greco-Roman period; what sort of sport was practised in Olympia? Who were the participating athletes and, above all, why did they practice their sports and why did they participate in the Olympics? Was it the case that it was a gentlemanly amateur activity and that commercialism in sport is just a modern deviation?

Purpose:To assess the relationships between player characteristics (including age, playing experience, ethnicity, and physical fitness) and in-season injury in elite Australian football.Design:Single-cohort, prospective, longitudinal study.Methods:Player characteristics (height, body mass, age, experience, ethnicity, playing position), preseason fitness (6-min run, 40-m sprint, 6 × 40-m sprint, vertical jump), and in-season injury data were collected over 4 seasons from 1 professional Australian football club. Data were analyzed for 69 players, for a total of 3879 player rounds and 174 seasons. Injury risk (odds ratio [OR]) and injury severity (matches missed; rate ratio [RR]) were assessed using a series of multilevel univariate and multivariate hierarchical linear models.Results:A total of 177 injuries were recorded with 494 matches missed (2.8 ± 3.3 matches/injury). The majority (87%) of injuries affected the lower body, with hamstring (20%) and groin/hip (14%) most prevalent. Nineteen players (28%) suffered recurrent injuries. Injury incidence was increased in players with low body mass (OR = 0.887, P = .005), with poor 6-min-run performance (OR = 0.994, P = .051), and playing as forwards (OR = 2.216, P = .036). Injury severity was increased in players with low body mass (RR = 0.892, P = .008), tall stature (RR = 1.131, P = .002), poor 6-min-run (RR = 0.990, P = .006), and slow 40-m-sprint (RR = 3.963, P = .082) performance.Conclusions:The potential to modify intrinsic risk factors is greatest in the preseason period, and improvements in aerobic-running fitness and increased body mass may protect against in-season injury in elite Australian football.

Background: Rugby union is a physically demanding sport that carries an inherent risk of injury. Despite being a popular and widely played team sport, little is known about injuries occurring across the male and female amateur game. Purpose: To establish and compare injury incidence, nature, and severity in male and female Irish amateur rugby union. Study Design: Prospective cohort study. Level of Evidence: Level 3. Methods: Data were collected prospectively from 25 male teams (959 players) and 8 female teams (234 players) over 2 full seasons. Both time-loss (24-hour time-loss injury definition) and non-time-loss match injury reports were collected, alongside match exposure data. Results: Time-loss match injury incidence rates were 49.1/1000 and 35.6/1000 player-hours for male and female players, respectively. Concussion and ankle ligament sprains were the most common diagnoses for male (5.6/1000 and 4.4/1000 player-hours, respectively) and female players (5.5/1000 and 3.9/1000 player-hours, respectively). Anterior cruciate ligament injuries presented the highest injury burden for male and female players with 200.3 and 307.2 days of absence per 1000 player-hours, respectively. In female players, 83% of noncontact injuries occurred in the fourth quarter of match play. Conclusion: While female players had a lower overall injury incidence rate compared with male players, concussion and ankle ligament injuries were the most common injuries in both cohorts. In female players, a high rate of noncontact injuries in the second half points to the need for strength and conditioning training programs to reduce fatigue-related injuries. Clinical Relevance: Establishing the incidence and burden of rugby-related injuries is an essential step in minimizing injury risk. This epidemiological information will aid the development of future reduction strategies, including education and coaching strategies and strength and conditioning programs, informed by the most common injuries observed and the mechanism of injury.

The article presents the analysis of the peculiarities of the selection systems for athletes-candidates to the Ukrainian national team for participation in the Olympic Games (on the example of combat sports). The urgency of the work is due to the need to develop and implement a modern model of Olympic training in combat sports, which would allow the athletes to compete successfully in the international arena. The purpose of the study was to determine the features of the current selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games (on the example of combat sports). Material and methods. Theoretical analysis, generalization of literature and Internet data, documentary method allowed to identify trends in modern Olympic combat sports and analyze the selection systems governing the inclusion of Ukrainian athletes in the starting lineup of participants in the Olympic Games in modern combat sports (fencing, boxing, Free and Greco-Roman wrestling, judo, taekwondo, karate). Results and discussion. Most of the provisions of the selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games are similar. In most combat sports, selection is based on an analysis of the performances of athletes in national and international competitions, competitiveness and the results of personal fights with major rivals who will participate in the Olympic Games. Selection for the starting lineup of the team at the main competitions of the season or four-year Olympic cycle consists of several stages, each of which determines a different number of athletes-candidates for the national team. As the year of the next Olympic Games approaches, the number of candidates is decreasing proportionally. The peculiarity of all systems of national selection in modern Olympic combat sports is that the athlete needs to realize his (her) potential in almost every competition during the annual macrocycle, as it depends on the prospect of his inclusion in the starting lineup of the national team at major competitions. Taking into account the fact that the body's adaptive capabilities are limited, it is important to determine the appropriateness of the athlete's performance in a particular tournament, taking into account his (her) position in national and world rankings, and other conditions governing its inclusion in the starting lineup. Conclusion. Differences in the selection systems are the mechanisms for determining the starting lineups of the team in the main competitions of the season or four-year Olympic cycle (demonstration of a certain result or winning a place in a particular tournament, position in the world rankings, obtaining an Olympic license)
