High School Sports Injury Statistics

Roughly 2.3 injuries occur for every 1,000 times a high school athlete steps onto a field or court, according to a national surveillance study covering 2015 through 2019. That translates to thousands of sprains, fractures, concussions, and surgeries every school year across the country. Football consistently tops the injury charts, but the risks shift in surprising ways depending on the sport, the athlete’s sex, and even the surface underfoot.

Which Sports Carry the Highest Risk

Between 2015 and 2019, athletic trainers across the U.S. logged 15,531 injuries during nearly 6.8 million athlete-exposures (an athlete-exposure being one athlete participating in one practice or game). Football had the highest injury rate at about 4 per 1,000 exposures, followed by girls’ soccer at roughly 2.7 and boys’ wrestling at about 2.4.¹ When researchers looked at severe injuries specifically, football again led the way, with wrestling second and girls’ basketball third.²

On the other end of the spectrum, some sports carry almost no measurable injury risk. An older but often-cited single-school study found zero injuries in boys’ tennis, golf, and swimming programs during the observation period.³ That doesn’t mean those sports are injury-proof, but it underscores how dramatically risk varies by activity. A parent evaluating whether their kid should play football versus swim is looking at an order-of-magnitude difference in expected injuries.

One consistent finding across studies: competition is riskier than practice. Injury rates are higher during games, where the intensity and stakes both climb. Sprains, strains, and concussions make up the bulk of those game-day injuries.⁴

How Injury Patterns Differ Between Girls and Boys

When you pool all high school sports together, boys sustain injuries at a higher overall rate than girls, mostly because football pushes the numbers up so heavily. But that top-line stat hides something important. In sports that both sexes play, girls often get hurt more than boys do and tend to sustain more severe injuries.

In a study of severe injuries across matched sports like soccer, basketball, and baseball/softball, girls had a roughly 28 percent higher severe injury rate than boys. In basketball alone, girls’ severe injury rate was about 43 percent higher.⁵ Researchers found similar patterns for lower-extremity injuries specifically: girls had higher rates in soccer, basketball, and every other gender-comparable sport studied, along with a greater share of injuries that were severe enough to require imaging.⁶

Knee injuries show an especially stark split. Although boys had a higher overall knee injury rate in one national study, girls were twice as likely to suffer a knee injury serious enough to need surgery. They were also twice as likely to sustain a noncontact major knee injury, the kind where no one tackled or collided with them; their knee just gave out during a cut or landing.⁷ An earlier study found that female basketball and soccer players had more knee surgeries, and ACL reconstructions in particular, than boys or girls in other sports.⁸

The ACL Problem

The anterior cruciate ligament tear is one of the most feared injuries in youth sports, and the data explains why. Two separate meta-analyses have confirmed that female high school athletes tear their ACLs at a significantly higher rate than males. One found that girls’ risk per exposure was about 57 percent greater; the other pegged it at around 40 percent greater.⁹¹⁰ The disparity is most extreme in basketball, where both studies found girls had roughly three to four times the ACL injury risk compared with boys.

The sports with the highest per-season ACL risk for girls are soccer, basketball, and lacrosse, in that order. For boys, football carries the greatest per-season risk, followed by lacrosse and soccer.¹¹ An interesting wrinkle: boys’ football produced the highest raw number of ACL tears in one review (273 in the dataset), simply because so many boys play football. But girls’ soccer had the highest incidence rate per exposure, meaning each individual practice or game carried more risk.¹²

Why female athletes tear their ACLs more often is not fully settled, but the leading explanations involve differences in anatomy (wider pelvis, narrower femoral notch), hormonal fluctuations affecting ligament laxity, and neuromuscular patterns in how girls tend to land from jumps and change direction. The good news is that some of those neuromuscular patterns are trainable, as discussed later.

Concussions Across Sports

Concussions have received enormous public attention over the past two decades, and rightly so. Across 20 high school sports, researchers counted about 2.5 concussions per 10,000 athlete-exposures. Football accounted for nearly half of all concussions by sheer volume, followed by girls’ soccer, boys’ wrestling, and girls’ basketball.¹³ When rates are compared per exposure, football still leads, with boys’ ice hockey and boys’ lacrosse close behind.

The sex-based pattern seen in other injuries shows up with concussions, too. In sports played by both sexes, girls sustain concussions at higher rates and concussions make up a larger share of their total injuries.¹⁴ A statewide study in Hawaii found the same thing: in four of five gender-comparable sports, girls had higher concussion rates than boys.¹⁵ Researchers debate whether this reflects genuine biological differences (such as weaker neck musculature), differences in reporting behavior, or both.

One comparison worth noting: high school football players actually sustain a greater proportion of fractures and concussions than their college counterparts, even though college players face a higher overall injury rate. The hits in college may be harder, but the high school athlete’s body is still developing and may be less conditioned to absorb them.¹⁶

Overuse Injuries, Specialization, and Throwing Arms

Not every high school sports injury comes from a dramatic collision or awkward landing. A national estimate found that about 8 percent of injuries were classified as overuse, meaning they developed gradually from repetitive stress rather than a single event. The lower extremity was the most common site for overuse problems, and the top diagnoses were muscle strains and tendinitis.¹⁷ Eight percent may sound small, but overuse injuries tend to linger. They pull athletes out of action for weeks and can become chronic if not managed properly.

One of the clearest risk factors for overuse injuries is early sport specialization. A meta-analysis found that highly specialized athletes had roughly 81 percent greater risk of overuse injury compared with athletes who kept their training diverse.¹⁸ A prospective study of high school athletes reached a similar conclusion: moderate and high sport specialization were associated with more lower-extremity injuries.¹⁹ The exact age at which specialization becomes risky isn’t nailed down, but the pattern is clear enough that sports medicine organizations widely encourage young athletes to play multiple sports.²⁰

Throwing sports illustrate the overuse problem well. In high school baseball, the majority of shoulder and elbow injuries are chronic and caused by overuse, and pitchers absorb the lion’s share. About 40 percent of shoulder injuries and 57 percent of elbow injuries happen to pitchers.²¹ Elbow and forearm injuries in baseball have actually been increasing over time, with one study finding a statistically significant upward trend across recent years. The same trend was not seen in softball.²² Year-round travel ball and showcase tournaments may be fueling this rise, as young arms get less recovery time between seasons.

What the Playing Surface Does to Injury Risk

As more high schools install artificial turf, the question of whether synthetic surfaces increase injury risk has become pressing. A national study comparing ACL injury rates on artificial turf versus natural grass found that ACL tears were more likely on turf in both football and girls’ soccer. The association in football showed about a 23 percent higher likelihood on turf; in girls’ soccer, it was around 53 percent higher.²³ The relationship for boys’ soccer was in the same direction but did not reach statistical significance in the overall analysis.

Biomechanical testing helps explain why. When researchers dropped accelerometers onto high school fields to measure impact forces from simulated falls, synthetic turf produced significantly greater deceleration forces than natural grass in forward and backward falls.²⁴ In practical terms, turf doesn’t give as much as grass does when a player plants, cuts, or falls. That extra stiffness may contribute to the higher ACL injury rates. For schools weighing the convenience and lower maintenance costs of turf against player safety, these findings are worth factoring in.

What Has Actually Reduced Injuries

The injury picture isn’t all grim. Several interventions have demonstrably brought numbers down.

Neuromuscular warm-up programs, sometimes called “prehab,” target the movement patterns that lead to lower-body injuries. A controlled trial in female soccer and basketball players at urban public high schools found that athletes using a neuromuscular warm-up had dramatically lower rates of noncontact lower-extremity injuries. Noncontact ACL injuries dropped by about 80 percent in the intervention group.²⁵ A separate cluster-randomized trial in junior high school students found that a neuromuscular warm-up cut lower-extremity injuries by about 64 percent for girls, though the effect was not significant for boys.²⁶ These programs typically take 15 to 20 minutes and include dynamic stretching, balance work, plyometrics, and strengthening exercises. The barrier isn’t complexity; it’s adoption. Coaches need to dedicate the time, and many don’t.

Rule changes have also made a measurable dent, especially in football. When states began limiting full-contact practice time, the results were striking. One study found a 42 percent average decline in head-impact exposure across all positions, with linemen seeing the biggest drop.²⁷ A related study confirmed that practice concussion rates fell significantly after the rule change, from about 0.76 per 1,000 exposures down to 0.33, though game concussion rates stayed flat.²⁸ Separately, a targeting rule implemented in 2014 to penalize helmet-to-helmet contact was followed by a reversal of helmet-to-helmet concussion trends: concussions from that mechanism had been rising about 18 percent per year before the rule but declined about 6 percent per year afterward.²⁹

Catastrophic Heat-Related Deaths

The rarest but most devastating sports injuries are fatal ones. Exertional heat stroke is among the leading causes of death in high school athletes, and football accounts for an overwhelming share. Over a four-decade review from 1982 through 2022, 67 deaths from exertional heat stroke were identified in secondary school sports. Football was responsible for 63 of those 67 deaths. Almost all victims were male, and most deaths occurred in August and July, when preseason practices coincide with extreme heat.³⁰ The southern United States accounted for about three-quarters of all cases.

These deaths are considered preventable with proper protocols: acclimatization periods, mandatory water breaks, wet-bulb globe temperature monitoring, and on-site cold-water immersion tubs. Yet a study evaluating state-level adoption of safety policies found wide variation. States scored anywhere from 23 percent to 79 percent on implementation of evidence-based best practices for preventing sudden death in secondary school sports, which includes not only heat stroke but also sudden cardiac arrest, head injuries, and exertional sickling.³¹ Your child’s level of protection depends heavily on which state you live in.

The Role of Athletic Trainers

Whether a school has a certified athletic trainer on staff affects both how injuries are identified and how they are managed. The American Medical Association has long recommended that certified athletic trainers be present at high school sporting events to ensure injuries are recognized early, treated immediately, and given enough time to heal before athletes return to play.³²

Research on high school football programs found that full-time, school-employed athletic trainers reported higher overall injury rates than part-time or outreach trainers, but the rates converged when only time-loss injuries were counted. The interpretation isn’t that full-time trainers cause more injuries; it’s that they catch and document more of them, including minor ones that might otherwise go unreported.³³ That surveillance matters. An unreported concussion that goes without rest is far more dangerous than one properly managed from day one.

Sleep, Nutrition, and the Injuries You Don’t See Coming

Some of the most modifiable risk factors have nothing to do with technique or equipment. A study of adolescent elite athletes found that sleeping more than eight hours on weeknights cut the odds of a new injury by about 61 percent. Meeting recommended nutritional intake cut the odds by a similar amount.³⁴ High school athletes juggling early school start times, homework, social media, and training schedules frequently fall short of both. These aren’t glamorous interventions, but they may be among the most effective ones available.

Mental Health and Long-Term Physical Consequences

The damage from a high school sports injury doesn’t always end when the cast comes off. Athletes who miss three or more weeks from injury show significantly worse emotional outcomes, and female athletes, those with higher injury severity, and athletes who strongly identify with their sport are at elevated risk for depressive symptoms.³⁵ A systematic review confirmed that musculoskeletal injury is broadly associated with worse mental health in young athletes, with strong athletic identity acting as a risk factor for depression after injury.³⁶ This is an area that coaches and parents often overlook. A teenager whose entire social world revolves around their team can spiral quickly when they are suddenly sidelined.

Physically, the consequences can surface years later. Research tracking young people three to ten years after a sport-related knee injury found that they reported more symptoms, worse physical function, and a greater likelihood of being overweight or obese compared with matched uninjured peers. These changes are consistent with early post-traumatic osteoarthritis, a condition that, once underway, tends to progress.³⁷ A torn ACL at sixteen doesn’t just mean missing a season. It can mean a knee that aches at thirty.

Socioeconomic Gaps in Injury Rates

Injury risk is not evenly distributed across school districts. During the 2020–2021 school year, when COVID-19 disrupted training schedules and access to facilities, injury rates rose across most socioeconomic levels. Schools in the lowest income bracket (median household income under $30,000) saw their injury incidence nearly double compared with the prior year. Schools in the $30,000 to $50,000 bracket roughly doubled as well. Before the pandemic, there had been a measurable association between higher household income and higher injury incidence, likely reflecting greater access to athletic trainers who documented injuries. That association disappeared during the pandemic year, suggesting that the disruptions in conditioning and care hit lower-income schools especially hard.³⁸ Wealthier schools are more likely to have full-time athletic trainers, better facilities, and stronger conditioning programs, all of which affect not only how many injuries happen but how many get counted, treated, and prevented.
