“…Several studies have found that players with the XX genotype have certain susceptibility to developing non-contact musculoskeletal injury [ 18 , 19 ] and need more recovery time to return to play after this type of injury [ 20 ]. Probably, the lower values of quadriceps and hamstrings isokinetic strength in XX than RR players constitute a disadvantage to prevent muscle injuries in football [ 21 ], as most of the non-contact muscle injuries in football are located at the thigh, with a particularly high incidence in hamstring muscle [ 22 ]. However, these findings have been found in samples of male professional football players, while the influence of the ACTN3 XX genotype on the probability of non-contact muscle injury—or any other type of injury— has not been tested in professional women football players.…”

The p.R577X polymorphism (rs1815739) in the ACTN3 gene causes individuals with the XX genotype to be deficient in functional α-actinin-3. Previous investigations have found that XX athletes are more prone to suffer non-contact muscle injuries, in comparison with RR and RX athletes who produce a functional α-actinin-3 in their fast-twitch fibers. This investigation aimed to determine the influence of the ACTN3 R577X polymorphism on physical performance and injury incidence of players competing in the women’s Spanish first division of football (soccer). Using a cross-sectional experiment, football-specific performance and epidemiology of non-contact football-related injuries were recorded in a group of 191 professional football players. ACTN3 R577X genotype was obtained for each player using genomic DNA samples obtained through buccal swabs. A battery of physical tests, including a countermovement jump, a 20 m sprint test, the sit-and-reach test and ankle dorsiflexion, were performed during the preseason. Injury incidence and characteristics of non-contact injuries were obtained according to the International Olympic Committee (IOC) statement for one season. From the study sample, 28.3% of players had the RR genotype, 52.9% had the RX genotype, and 18.8% had the XX genotype. Differences among genotypes were identified with one-way analysis of variance (numerical variables) or chi-square tests (categorical variables). Jump height (p = 0.087), sprint time (p = 0.210), sit-and-reach distance (p = 0.361), and dorsiflexion in the right (p = 0.550) and left ankle (p = 0.992) were similar in RR, RX, and XX football players. A total of 356 non-contact injuries were recorded in 144 football players while the remaining 47 did not sustain any non-contact injuries during the season. Injury incidence was 10.4 ± 8.6, 8.2 ± 5.7, and 8.9 ± 5.3 injuries per/1000 h of football exposure, without differences among genotypes (p = 0.222). Injury rates during training (from 3.6 ± 3.7 to 4.8 ± 2.1 injuries per/1000 h of training exposure, p = 0.100) and match (from 47.8 ± 9.5 to 54.1 ± 6.3 injuries per/1000 h of match exposure, p = 0.209) were also similar in RR, RX, and XX football players. The ACTN3 genotype did not affect the mode of onset, the time needed to return to play, the type of injury, or the distribution of body locations of the injuries. In summary, women football players with different genotypes of the p.R577X ACTN3 polymorphism had similar values of football-specific performance and injury incidence. From a practical perspective, the ACTN3 genotyping may not be useful to predict performance or injury incidence in professional women football players.

“…Epidemiological research in soccer has been done all over the world to address the various factors such as lost training time due to injury, injury prevention, and possibly performance enhancement [1][2][3][4][5] . In 2006, Fuller et al 2) announced a consensus statement for defining injury and data collection of soccer injuries.…”

Injury can possibly change an athlete's career. To date, few epidemiological studies have been made of amateur soccer players. More data is needed to allow medical professionals to develop realistic injury prevention and conditioning programs for the amateur level. The purpose of this study was to determine injury incidence, common injury types and body regions, and pain in amateur soccer players. Soccer-related injury and pain data were collected daily in June 2016 thorough October 2017 involving 76 amateur soccer players from two teams. Overall injury incidence was 69 injuries and 2.72/1000 player hours. Acute injuries were 52 (2.05/1000 player hours) and chronic injuries were 17 (0.67/1000 player hours). Most acute injuries occurred during a game (1.99/1000 player hours). In terms of body regions, ankle injury (27.5%) was the most common, followed by knee (15.9%), and thigh (9.0%). Pain incidence was reported 1042 (41.10/1000 player hours). The highest pain incidence was reported during a game (36.9/1000 player hours). The most common location of pain was foot/toe (5.80/1000 player hours), followed by lateral ankle (5.21/1000 player hours), anterior thigh (3.98/1000 player hours), and groin (3.27/1000 player hours). Type of injury, location of injury, and the higher incidence of injury during a game, as opposed to training, were the same as other studies. The pain incidence rate was higher than injury incidence. More epidemiological studies are needed in amateur sports to better understand athletes' injuries and pain and be able to develop an appropriate injury prevention strategy.

“…Recent studies show that even in Under 20 soccer players the hamstring injury incidence has its relevance, reaching 18% of total traumas (Ribeiro-Alvares et al, 2020;) or about 35%, according to other epidemiological studies (Valle et al, 2018). ; even young players have very high risk factors of injury, such as reduced active flexibility, lower limb asymmetry, functional and core stability deficits (Buckthorpe et al, 2019;Crossley et al, 2020;Lu et al, 2020).…”

The study purpose.The Small-side games (SSG) are high intensity drills very popular in soccer training. The knowledge of the acute effects of the exercises that make up the training session is very relevant especially to reduce youth soccer injury risk. This study aim to assessment the acute effects of SSG on hamstring eccentric strength and to know the lower limb strength asymmetries (LLSA) in young soccer players. Materials and methods. The sample is composed of male young soccer players Under 17 (n = 24, 16.6 ± 0.5 years, 168.8 ± 4.6 cm, 58.2 ± 3.5 kg). Before and after SSG (4vs4, 3×4 min, 3min recovery, no goalkeepers) the hamstring eccentric strength and the lower limb eccentric strength asymmetry were evaluated used a specific dynamometer (N3 Easytech, Italy) and relative software. Every young soccer player performed a single repetition of the Nordic hamstring exercise with dynamometer; after about 2 minutes, instead, they performed 5 repetitions of the same exercise, without interruption. For both assessments, were detected the eccentric strength and the LLSA. Results. The hamstring eccentric strength assessment show substantial and statistically significant differences in the assessment in comparison pre-post values. A significant reduction was observed for eccentric strength peak (p < 0.018 and p < 0.014 for right/left limb), for eccentric average strength (p < 0.017 and p < 0.006 for right/left limb). The eccentric peak strength asymmetry value and the average strength asymmetry value revealed a significant increase (p < 0.0001). Conclusions. The reduction of strength after SSG requires careful consideration of the exercises order in the training session. The practitioners can plan training sessions and apply SSGs more effectively, with more attention to the effects on hamstrings.
