Every soccer fan has witnessed that heart-stopping moment when a star player crumples to the ground, clutching their leg or holding their head. For Liverpool’s Virgil van Dijk, that moment came in October 2020 during a collision with Everton’s goalkeeper Jordan Pickford. The resulting anterior cruciate ligament (ACL) injury sidelined him for nearly 300 days, threatening not just his season but potentially his career. Van Dijk later reflected on the psychological impact: “The first two weeks were horrible. I could not do anything. You lied on your bed, losing your muscles and watching yourself get slimmer.”
Unfortunately, stories like Van Dijk’s are becoming increasingly common. A comprehensive new study published in Current Sports Medicine Reports examining injury prevention in professional football reveals a troubling pattern: while we know more about soccer injuries than ever before, preventing them remains a significant challenge. The study’s authors note that “although there are a few preventative programs that are available and used among professional football players, there is generally a lack of high-quality evidence to support their use.”
With an estimated injury rate of 8 per 1,000 hours of play among professional footballers, and the lower extremity accounting for up to 80% of all injuries, the beautiful game exacts a heavy physical toll on those who play it at the highest level. The study emphasizes that “musculoskeletal injuries are the most common type of injury, with the most frequent being muscle/tendon, ligament/joint, and contusion injuries.”
The Hamstring Epidemic
Among professional footballers, hamstring injuries have become particularly problematic, accounting for approximately 17% to 24% of all injuries and showing a steady increase over the past two decades. Stars like Cristiano Ronaldo, Arjen Robben, and Paul Pogba have all battled these injuries throughout their careers. The increase appears linked to the growing intensity of modern soccer, with players covering more ground at higher speeds than ever before.
The study highlights the severity of this problem: “In elite professional football, hamstring injuries account for approximately 17% to 24% of all injuries and appear to be increasing over the previous 20 years. In addition, hamstring injuries now account for a larger burden on clubs, accounting for a total of 20% of all days lost.”
What makes hamstring injuries especially frustrating is their tendency to recur. The recurrence rate sits at approximately 13% to 18%, and when players suffer a second hamstring injury, they typically miss even more time than they did with the first one. For a professional team, this translates to roughly 90 days of lost time per season—equivalent to 15 to 21 missed matches per club. When you consider that a professional club averages about 10 hamstring injuries per season, the economic and competitive impact becomes staggering.
Most hamstring injuries occur during high-speed movements—sprinting, changing direction, or kicking—when the muscle is stretched while simultaneously contracting. Video analysis of professional matches shows that 71% of hamstring injuries happen at high or very high speeds, with the biceps femoris (the largest hamstring muscle) being the most commonly affected.
The good news? Research suggests that specific exercises can help. Studies show that incorporating the Nordic hamstring exercise into training programs can cut hamstring injury rates in half. This deceptively simple exercise, where players kneel and slowly lower themselves forward while a partner holds their ankles, strengthens the hamstring in ways that directly combat injury mechanisms. The study notes that “the current research appears to present a reduced risk of injury with the implementation of the Nordic hamstring in clubs’ strengthening programs.” Additionally, ensuring players are exposed to regular sprint training and incorporating dynamic warm-ups have shown protective effects.
Groin and Adductor Injuries: The Silent Epidemic
While hamstring injuries grab headlines, hip and groin injuries represent another major concern, accounting for 4% to 19% of all injuries in professional male football. These injuries share the hamstring’s frustrating characteristic of high recurrence rates, ranging from 11% to 15%. The study emphasizes that “as a primary driver of time lost in professional football, adductor-related injuries account for 4% to 19% of aggregated injuries in men’s senior football and 2% to 14% in women’s senior football.”
The Copenhagen Adductor Exercise has emerged as a leading prevention strategy, though researchers note that while it significantly improves strength, the evidence for actual injury reduction remains somewhat unclear. The study points out that “while the CAE has been widely researched for both preventing and treating adductor injuries, the evidence for significant reductions injury rates remains unclear. However, it has been shown to produce significant changes in strength.”
The ACL Crisis
Perhaps no injury strikes more fear into players and fans than an ACL tear. Female players face approximately double the ACL injury risk compared to their male counterparts, a disparity that has prompted urgent calls for gender-specific prevention programs. The study clearly states that being “female” is listed among the potential risk factors for ACL rupture, alongside “poor biomechanics (especially dynamic valgus).”
Beyond Van Dijk, numerous elite players have faced this devastating injury. England striker Alan Shearer suffered an ACL tear during his debut season at Blackburn Rovers in 1992, yet bounced back to become the Premier League’s all-time leading scorer with 260 goals. Italian legend Alessandro Del Piero spent a year on the sidelines after his 1998 ACL injury but adapted his playing style and continued performing at the highest level for over a decade, ultimately helping Italy win the 2006 World Cup.
However, research on programs like FIFA 11+—a structured warm-up routine focusing on strength, balance, and proper movement patterns—has shown promise in reducing ACL injuries. The key lies in addressing modifiable risk factors such as poor landing mechanics, inadequate core strength, and what researchers call “dynamic valgus”—when the knee collapses inward during landing or cutting movements.
For those who do suffer ACL tears, the road back is long but increasingly successful. Most elite players require seven to nine months before returning to competition, though the psychological recovery can take even longer. As Van Dijk noted about his own recovery, “I also heard that 75% of players suffering from an ACL injury had struggled to return to their form. I have done my research and I worked to recover my level.” Research confirms that while most players do return to pre-injury performance levels, it often takes 18 to 24 months to fully regain strength, conditioning, and overcome the mental challenge of trusting the repaired knee. The study notes that “the research shows that most footballers do return to their pre-injury levels of performance BUT it often takes 18-24 months to return to pre-injury strength and conditioning and also get over the mental challenge of regaining confidence in movement, the knee, and the fear of reinjury.”
The Concussion Conundrum
Head injuries present a different kind of challenge. The incidence of head and neck injuries in professional football ranges between 0.9 and 1.7 per 1,000 player-hours for men, with women facing rates of 1.8 per 1,000 player-hours. These injuries occur more frequently during matches than training, highlighting the competitive intensity of game situations. According to the study, “several studies have shown that the incidence is markedly increased during matches as opposed to training.”
Contrary to popular belief, most concussions don’t come from heading the ball itself. Dr. Thomas Kaminski, a leading expert on soccer concussions and the sole U.S. representative to the FIFA Heading Expert Group, explains: “They could be going up to head the ball and come into contact with another player—head-to-head, elbow-to-head, or head-to-ground—and those types of concussions can be devastating.”
Research supports this distinction. When heading is performed with proper technique—contracting neck muscles to stabilize the head and making contact with the forehead—the impact force is typically insufficient to cause a concussion. However, unintended head impacts, particularly player-to-player collisions while competing for headers, generate far more dangerous forces. The study notes that “it is known that unintended headers lead to more SRC than purposeful heading.”
One of the most effective prevention strategies has been implementing rule changes, such as red cards for elbow-to-head contact. The study cites compelling evidence from Germany: “Data from the German Bundesliga compared head injury and SRC before and after the enforcement of red cards for elbow-to-head contact, and found that the incidence of head injuries was significantly decreased after rule changes.” This simple policy intervention achieved what protective equipment could not—a measurable reduction in head injuries without requiring players to wear additional gear.
Education programs have also proven valuable, with coaches trained in concussion recognition showing lower injury rates among their players. The study highlights that “in two studies, it was shown that the CDC HEADS UP program increased prevention and improved management of SRC in high school sports.” U.S. Soccer’s heading restrictions for youth players—prohibiting heading for children under 11 and limiting practice heading for 12-13 year-olds—reflect growing awareness of protecting developing brains.
The Ankle Problem
Often overlooked in discussions of major injuries, ankle sprains constitute approximately 10% to 19% of all professional football injuries, making them the third most common injury type. What’s particularly concerning is that ankle injuries have the highest recurrence rate of any lower limb injury, with about half of players developing chronic ankle instability. The mechanism is typically an inversion (rolling outward) of the ankle during landing, direction changes, or after contact with an opponent’s foot. Evidence suggests that ankle bracing and taping can effectively reduce both initial and recurrent sprains, though this adds considerable cost and preparation time to training and matches.
The Heart of the Matter
While muscle and joint injuries dominate the headlines, sudden cardiac death in athletes, though rare, remains a critical concern. The study emphasizes that “most deaths in young athletes are due to a diverse spectrum of inherited or congenital abnormalities of the heart that can be detected during life and for which there are several therapeutic interventions to mitigate the risk of SCD.”
Screening programs involving health questionnaires, physical examinations, and electrocardiograms have proven effective. One Italian screening program demonstrated remarkable success, with the study reporting that it “suggests that the European screening protocol is effective in reducing the number of SCDs from 3.6 per 100,000 to 0.4 per 100,000.” This dramatic reduction shows that proper screening can save lives.
However, the study also cautions that “no single cardiac investigation will identify all diseases,” making emergency preparedness equally crucial. The presence of automated external defibrillators (AEDs) and trained staff capable of performing CPR can mean the difference between life and death when cardiac events do occur.
The Path Forward
Despite these advances, the study reveals a sobering reality: there is generally a lack of high-quality evidence supporting most injury prevention programs used in professional football. The authors emphasize this critical gap: “In general, evidence for effectiveness of most injury prevention strategies in football is weak. Most injury prevention programs include different combinations of the following exercises: 1) warm-ups, 2) strengthening, and 3) balance and proprioception.”
Many strategies currently employed by teams are based on theory and tradition rather than rigorous scientific proof. Most prevention studies combine multiple interventions—warm-ups, strengthening exercises, and balance training—making it difficult to determine which specific components actually work. As the study notes, “a meta-analysis of 10 original randomized controlled trials (RCTs) presents weak evidence that the risk of noncontact MSK injuries in football can be reduced by exercise-based prevention programs.”
The researchers emphasize an urgent need for football leagues worldwide to collaborate with medical and research teams to conduct high-level studies. Creating an international injury registry appears to be a crucial first step toward understanding injury patterns across different leagues, playing styles, and populations. The study concludes: “There is a glaring need for football leagues, in conjunction with medical and research teams, to design and conduct high-level studies in an attempt to close our knowledge gap in regard to injury prevention in football. Creating an international injury registry seems to be an important step toward this goal.”
Currently, methodological differences between studies—including how injuries are defined and exposure calculated—make meaningful comparisons nearly impossible. The study highlights this challenge: “While there are many published studies on injury epidemiology in football, the heterogenicity in their methodology (e.g., retrospective, publicly available data, exposure definition) and competition level, makes it difficult for meaningful comparison.”
There’s also a critical need for more research on women’s football. The authors note: “From 1970 until 2019, 19.3% of all papers on football and 15.5% on professional football had a female focus.” This disparity is particularly concerning given evidence suggesting different injury patterns and risk factors. The ACL injury disparity alone demands targeted investigation into whether anatomical, hormonal, or biomechanical differences require different prevention approaches.
For now, the message to players, coaches, and medical staff is clear: focus on evidence-based prevention strategies like the Nordic hamstring exercise and FIFA 11+ program, prioritize proper technique training, and never rush players back from injury. As Van Dijk’s successful return demonstrates, patience and proper rehabilitation can help even the most severe injuries heal. He reflected: “Today, I returned to where I wanted to be. I’m the same player as before.”
The beautiful game demands physical excellence, but protecting those who play it requires constant vigilance, better research, and a commitment to putting player safety first. With professional football’s global reach and resources, there’s unprecedented opportunity to conduct the large-scale studies needed to truly understand how to keep players healthy and on the pitch where they belong. As the study’s authors remind us, the stakes are high: “Professional football is not without risk for developing injuries that may influence athletes’ short-term and long-term careers.”
