Main results: Youth soccer is a relatively safe sport with an injury incidence ranging from 2.3 per 1,000 practice hours to 14.8 per 1,000 game hours. Similar to adults, youth soccer injuries occur mostly in the lower extremities, specifically the knee and ankle. Contusions are the most common injury, and minor/moderate injuries predominate.
Youth soccer has a greater reported injury rate than many other contact sports, and recent studies suggest that injury rates are increasing. Large increases in the incidence of concussions in youth soccer have been reported, and anterior cruciate ligament injuries remain a significant problem in this sport, particularly among female athletes.
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.
As a typical contact sport, soccer may result in various injuries. The majority of them affect talocrural joint, knee or inguinal region, however; 4% to 22% of all soccer injuries are related to head injuries with the incidence of 1.7 injuries per 1000 playing hours (7-13).
Repetitive ankle injuries in soccer players may cause chronic ankle instability, which includes both mechanical ligamentous laxity and functional changes. Chronic ankle pathology often requires surgery to repair ligamentous damage and remove soft-tissue or osseous impingement.
As one of the most popular sports in the world, soccer injury rates involving the knee continue to rise. An alarming trend of knee injuries, including increased anterior cruciate ligament ruptures, underscores the need to review our current understanding of these injuries in soccer players.
Conclusions: Female players suffer a high amount of head injuries and severe knee and ankle injuries. The most common single injury is a sprained ankle. Torn ligaments in the ankle and knee are the most common injuries that require a long recovery period. Most of the severe injuries (>30 days) are due to noncontact intrinsic mechanisms.
Participant demographics are outlined in Table 1. These players sustained a total of1565 injuries: 632 (40%) were medical attention injuries and 933 (60%) were TLIsresulting in 17,772 days lost (Table 2). A total of 736 (47%) injuries occurred in training and 829(53%) in games.
