Objectives To determine the incidence and characteristics of injury and illness in English men’s and women’s senior and youth international football. Methods Time-loss injuries and illnesses, alongside match and training exposure, were collected across 8 seasons (2012–2020) in youth (U15, U16, U17, U18, U19) and senior (U20, U21, U23, senior) English men’s and women’s international teams. Analysis of incidence, burden, and severity of injury and illness was completed. Sex-specific comparisons were made between the senior and youth groups, and across the 8 seasons of data collection. Results In men’s international football, 535 injuries were recorded (216 senior; 319 youth) during 73,326 h of exposure. Overall, match injury incidence (31.1 ± 10.8 injuries/1000 h) and burden (454.0 ± 195.9 d absent/1000 h) were greater than training injury incidence (4.0 ± 1.0 injuries/1000 h) and burden (51.0 ± 21.8 d absent/1000 h) (both P
Epidemiology of Injuries in Men’s Professional and Amateur Football (Part I)
Journal of Clinical Medicine
Background (1): Football is the most popular sport among men, associated with a certain risk of injury, which leads to short- and long-term health consequences. While the injury profile of professional footballers is known, little is known about the injury profile of amateur footballers; amateur football is a major and diverse area, the development of which should be a priority for football associations around the world and UEFA. The aim of this study was to perform a systematic review of epidemiological literature data on injuries in professional and amateur football players belonging to certain leagues. Methods (2): A systematic review according to the PRISMA guidelines was performed until June 2023 in the databases PubMed, Web of Science, Google Academic, Google Scholar, and Diva portal. Forty-six studies reporting injury incidence in professional and amateur men’s football were selected and analyzed. Two reviewers independently extracted data and assessed study quality using an ...
The influence of match frequency on the risk of injury in professional soccer
International Sportmed Journal, 2013
Background: To the best of these authors' knowledge, no previous study of professional soccer players playing different match frequencies has been conducted to investigate the risk of injury at the highest club competitive level in South America. Research question: To analyse the risk of injury in professional soccer players involved in two tournaments with different match frequencies. Type of study: Prospective cohort study. Method: A total of 95 professional players from several Argentinian teams were included. Forty players were involved only in the National Championship (Low Match Frequency, LMF) and 55 players took part in both tournaments: the National Championship and the Libertadores Cup (High Match Frequency, HMF). Exposure to football and injury incidence, severity and distribution were compared between LMF and HMF players. Results: HMF players had greater exposure to matches (18.6 vs. 14 matches per season p<0.01), whereas exposure to training did not differ. There was a higher risk of injury during training (4.5 vs. 1.2 /1000 h, p<0.01) and total exposure (8.9 vs. 5.0 /1000 h, p<0.01) in HMF players than in LMF players, whereas no difference was observed with respect to matches played. After an injury, HMF players had longer absences from matches played (3.5 vs. 1 match, p<0.01), training (14.4 vs. 6.8 days, p<0.01) and total exposure (21.7 vs. 9.4 days, p<0.01). The most prevalent diagnoses were muscular and tendon injuries more frequently observed in HMF players (55.4 % vs. 44.8 %, p<0.05). Conclusions: Professional soccer players involved in two tournaments are exposed to a higher risk of injury. This phenomenon would have a greater influence on training sessions than on matches played.
Epidemiology of injury in English Professional Football players: A cohort study
Physical Therapy in Sport
Main Outcome Measure: Injury incidence, training and match exposure were collected in accordance with the international consensus statement on football injury epidemiology. Results: 473 injuries were reported. The estimated incidence of injury was, 9.11 injuries/1000h of football related activity. There was a higher incidence of injury during match play (24.29/1000h) compared to training (6.84/1000 hours). The thigh was the most common site of injury (31.7%), muscle strains accounted for 41.2% of all injuries. The hamstrings were the most frequently strained muscle group, accounting for 39.5% of all muscle strains and 16.3% of all injuries. Moderate severity injuries (8-28 days) were the most common (44.2%). Conclusions: Incidence of injury has increased over the last 16 years with muscle strains remaining the most prevalent injury. The hamstrings remain the most commonly injured muscle group.
Epidemiology of Injuries in Professional and Amateur Football Men (Part II)
Journal of Clinical Medicine
Background (1): Men’s football is a physically demanding contact sport that involves intermittent bouts of sprinting, jogging, walking, jumping and changes of direction. The physical demands of the game vary by level of play (amateur club, sub-elite and open club or international), but injury rates at all levels of the men’s football game remain the highest of all sports. Objective: The aim of this study is to conduct a systematic review of data from the epidemiological literature regarding the profile, severity and mechanisms of injuries and the frequency of recurrent injuries in professional and amateur football players. Methods (2): A systematic review, according to PRISMA guidelines, was performed up to June 2023 in the databases of PubMed, Web of Science, Google academic, Google scholar and the Diva portal. Twenty-seven studies that reported data on the type, severity, recurrence and mechanisms of injury in professional and amateur men’s football were selected and analyzed. Two...

Purpose: To study the risk of soccer injuries in Argentine professional players with congested football calendar over two consecutive seasons. Methods: One hundred and one players in Argentine professional male soccer division (23.6 ± 4.5 yrs., 75.1 ± 5.6 kg., 177.9 ± 5.9 cm.) were followed prospectively for 1 year. The players were involved in two competitions at the same time: the National League and one international competition (the Libertadores Cup or the South American Cup, depending on the time of year). An injury report system was kept by the club's medical staff for all training sessions and matches. Time-lost injuries and exposure times were recorded individually for each player from the first day of pre-season until the last training session or match. Results: A total of 239 injuries were reported during 330 days of the soccer season. The number of team matches during this period ranged from 62 to 69 (a mean of 26 matches per individual player). Sixty one players from the total (60.4 %) sustained at least one injury in the season and 52.4 % of all injuries occurred during competition. Reinjuries constituted 9.2 % of all injuries. The overall injury incidence was 9.4 injuries/1000 hours (51.5 injuries/1000 match hours and 5.3 injuries per 1000/training hours). The risk of injury varied throughout the season, with training injury incidence peaking during March and August and match injury incidence peaking during March and September. The most frequent types of injuries were muscular (55.3 %) and ligament (sprain, rupture, 16.3 %). The most prevalent diagnoses were muscular contracture (25.1 %) and thigh strain (13 %), with posterior strains being more common than anterior ones (15 vs. 4 injuries). Each month 7.9 % of the team (8 players) was not able to train or play due to injury. The mean (SD) number of days absent per injury causing limitation in training or in match participation was 12.6 ± 19.1.Conclusions: Professional soccer players who play two tournaments at the same time are exposed to a high risk of injury;7.9 % of them were unable to play every month due to injury. The data confirm that the most common injury in soccer is the thigh strain typically involving the hamstrings.Training and match injuries incidence peaking were determined during the months immediately after pre-season period. This gives some cause for concern and it is worth further investigation.
Epidemiological Findings of Soccer Injuries During the 2017 Gold Cup
Orthopaedic journal of sports medicine, 2018
Surveillance programs are vital to analyze the cause and nature of lesions and ultimately establish protocols of action to lower injury rates. To evaluate the adherence of team doctors to an electronic surveillance system and determine the incidence and characteristics of injuries among soccer players participating in the 2017 Gold Cup. Descriptive epidemiological study. All data were collected from the electronic medical reports submitted during each match of the 2017 Gold Cup. Twelve teams participated in the tournament (each with 23 players), for a total of 276 players. A 19-question online survey was filled out by the team physician after each injury. Each report contained the player's number, the exact time of injury (minute of play), the location and diagnosis of injury as indicated by a previously defined code, and its severity in terms of the number of days of absence from training and match play. The electronic reporting system had a response rate of 100.0%, with 97.2% ...

Background: No previous study on adult football involving several different countries has investigated the incidence and pattern of injuries at the highest club competitive level. Objective: To investigate the risk exposure, risk of injury, and injury pattern of footballers involved in UEFA Champions League and international matches during a full football season. Method: Eleven top clubs (266 players) in five European countries were followed prospectively throughout the season of 2001-2002. Time-lost injuries and individual exposure times were recorded during all club and national team training sessions and matches. Results: A total of 658 injuries were recorded. The mean (SD) injury incidence was 9.4 (3.2) injuries per 1000 hours (30.5 (11.0) injuries per 1000 match hours and 5.8 (2.1) injuries per 1000 training hours). The risk of match injury was significantly higher in the English and Dutch teams than in the teams from France, Italy, and Spain (41.8 (3.3) v 24.0 (7.9) injuries per 1000 hours; p = 0.008). Major injuries (absence .4 weeks) constituted 15% of all injuries, and the risk of major injury was also significantly higher among the English and Dutch teams (p = 0.04). National team players had a higher match exposure, with a tendency towards a lower training injury incidence than the rest of the players (p = 0.051). Thigh strain was the most common injury (16%), with posterior strains being significantly more common than anterior ones (67 v 36; p,0.0001). Conclusions: The risk of injury in European professional football is high. The most common injury is the thigh strain typically involving the hamstrings. The results suggest that regional differences may influence injury epidemiology and traumatology, but the factors involved are unclear. National team players have a higher match exposure, but no higher risk of injury than other top level players.

Background: Injury surveillance has been used to quantify the scope of the injury burden in Australian football. However, deeper statistical analyses are required to identify major factors that contribute to the injury risk and to understand how these injury patterns change over time. Purpose: To compare Australian Football League (AFL) injury incidence, severity, prevalence, and recurrence by setting, site, and time span from 1997 to 2016. Study Design: Descriptive epidemiology study. Methods: A total of 15,911 injuries and medical illnesses recorded by team medical staff at each club were obtained from the AFL’s injury surveillance system and analyzed using linear mixed models with 3 fixed effects (setting, time span, site) and 1 random effect (club). All types of injuries and medical illnesses were included for analysis, provided that they caused the player to miss at least 1 match during the regular season or finals. Five-season time spans (1997-2001, 2002-2006, 2007-2011, and 2...
