“…Injuries can be divided into acute and overuse injuries. Injuries in football can take the form of joint injuries or dislocations (Light et al, 2018;Szymski et al, 2021;Sillanpää et al, 2022), muscle injuries (O'Boyle et al, 2020;Ménard et al, 2020), and ligament injuries (Silvers-Granelli et al, 2017;Rolley et al, 2022). Cases of childhood injuries are about 3% per year, but serious injuries occur only at 0.69% per year.…”

Football is one of the sports with the highest risk of injury, with injuries to children around 3% per year with serious injuries occurring at only 0.69% per year. The objective of the study is to investigate the application of FIFA 11+ Kids in minimizing sports injuries in youth football through enhancement components of physical condition, namely, leg muscle power and muscle flexibility. This study is an quasi-experimental research by using a pre-test - post-test control group design. The sample in this study are 20 people, divided into control and treatment groups. In this study, the sample is determined using a purposive sampling technique, with the following inclusion criteria: 1) male, 2) 11-12 years old, 3) practicing football regularly, 3) willing to be a research sample. In contrast, the criteria exclusion is experienced injured and unwilling to be a research sample. The distribution of control and treatment groups using matching subject ABBA technique. Instruments used in this research are the standing broad jump test to measure leg muscle power and sit and reach test to measure muscle flexibility. The data analysis is a t-test regression analysis with a level of 5% significance. This study found that the application of FIFA 11+ Kids can be used as a method to minimize sports injuries in youth football. The limitation of this study is that the sample is limited to only 20 children. This research is important because it contributes to the science of football coaching in terms of preventing injuries to children. Future research is expected to thoroughly examine the components of other physical conditions related to injury prevention, and use a larger sample from various age groups of soccer school students.

“…Besides multiple benefits, this analysis of data from the national ACL registry has also some limitations. The data basis was assessed by the ACL registry and a double-check registration of injuries through personal notice by the player or team and media based check by the study office [ 27 ]. Potentially, injuries cannot be recorded in this process.…”

“…This retrospective register study with prospectively collected data investigates ACL injuries in all professional football clubs in Germany and all non-professional clubs of the Bavarian Football Association in men’s football with regard to return to competition time and match performance for three seasons after injury. Injury data were registered in a standardized manner in the prospective nationwide ACL registry in German football since the 2014–15 season [ 27 ]. All male football players with a new ACL injury who had actively played in the German men's professional leagues (1st–3rd men’s professional league) or in the Bavarian amateur leagues (4th–7th men’s amateur league) were included into the study population.…”

“…Annually football officials, clubs and team physician were informed and invited to participate in the ACL registry in German Football and report new ACL ruptures to our study office. Parallelly, a double-check of the registration data by means of national media data was obtained by the study team by a standardized data collection method to avoid typical data loss and to decrease the drop-out rate [ 27 ]. Krutsch et al ([ 12 , 13 ]) validated the double-check system for media analysis for ACL injuries in football, where 100 % of injuries could be confirmed [ 12 , 13 ].…”

“…over 450 million worldwide) are accounted as recreational athletes and suffer from this increased risk of sustaining an ACL rupture [ 26 ]. With a season prevalence of 12.1 (range 6.8–15.9) ACL injuries for a recreational league and overall 2235 football leagues in Germany ( https://www.dfb.de/ ), number of around 27,000 (range 15,198–35,536) cruciate ligament ruptures due to playing and training activities in football can be expected in Germany every year [ 26 , 27 ]. Particularly for amateur players, a loss of time after an anterior cruciate ligament rupture with subsequent rehabilitation and a high number of sick-leave days mean an enormous burden [ 5 ].…”

Purpose ACL injuries are one of the most severe injuries in football, but medical consequences and performance outcomes after return to competition are only rarely investigated. Aim of this study was to analyse the time of return to competition (RTC) in German professional, semi-professional and amateur football. Also, this investigation highlights the rate of career ending and performance outcome after RTC in different playing levels by the measurement of playing level, performed matches and played minutes. Methods Database of this investigation is the ‘ACL registry in German Football’ with prospectively collected injury data. Between 2014 and 2018, four seasons in professional (1st–3rd league), semi-professional (4th–6th league) and amateur leagues (7th league) were analysed regarding the return to competition period and performance parameters. Data were collected for three subsequent seasons after injury and compared with the pre-injury and injury season. Data collection was performed using standardized methods. Results A total of 607 ACL injuries were registered during the 4-year period with a mean RTC time of 337.1 day (SD: 183). After primary ACL ruptures, the fastest RTC was found in professional football (247.3 days), while in semi-professional (333.5 d; p < 0.0001) and amateur football (376.2 d; p < 0.0001) a prolonged absence was detected. Re-ruptures occurred in 17.8% (n = 108) and showed similar trend with fastest RTC in professionals (289.9 days; p = 0.002). Within the first three seasons after injury, 92 players (36.7%) in semi-professional and 24 (20%) in professionals had to end their career. Keeping the level of play was only possible for 48 (47.5%) of professionals, while only 47 (29.6%) of semi-professionals and 43 (28.1%) of amateurs were able to. Only in professional football, no significant difference could be seen in the played minutes and games after 2 years compared to the pre-injury season. Conclusion Lower playing levels and re-ruptures are the main factors for a prolonged return to competition after ACL rupture in German football. Significant reduction in playing level and a high rate of career endings were found for all levels of play. However, only professional players were able to regain their playing minutes and games 2 years after injury, while lower classed athletes did not reach the same amount within 3 years. Level of evidence Level III.

Purpose Anterior cruciate ligament (ACL) injuries are a common severe type of football injury at all levels of play. A football-specific ACL registry providing both prospective ACL injury data according to the skill level and risk factors for ACL injury is lacking in the literature. Methods This study is based on the prospective ‘ACL registry in German Football’ implemented in the 2014–15 season. Professional (1st–3rd league), semi-professional (4th–6th league) and amateur leagues (7th league) were analysed regarding the incidence and risk factors for ACL injuries. Injuries were registered according to the direct reports of the injured players to the study office and double-checked via media analysis. After injury registration, the players received a standardised questionnaire. Data were analysed from the 2014–15 to the 2018–19 football season. Results Overall, 958 ACL injuries were registered during the 5-year study period. The incidence of ACL injuries was highest in amateur football (0.074/1000 h football exposure) compared to professional (0.058/1000 h; p < 0.0001) and semi-professional football (0.043/1000 h; p < 0.0001). At all skill levels, match incidence (professional: 0.343; semi-professional: 0.249; amateur: 0.319) was significantly higher than training incidence (professional: 0.015; semi-professional: 0.004; amateur: 0.005). Major risk factors were previous ACL injury (mean: 23.3%), other knee injuries (mean: 19.3%) and move to a higher league (mean: 24.2%). Conclusion This sports-specific ACL registry provides detailed information on the incidence and risk factors for ACL injuries in football over five years. Risk factors are skill level, match exposure, move to a higher league and previous knee injury. These factors offer potential starting points for screening at-risk players and applying targeted prevention. Level of evidence II.
