The most common injury in soccer is a hamstring strain. Hamstring injuries now account for 24% of all injuries in men’s professional soccer, and their rates have been climbing steadily over the past decade. The upper leg is the most frequently injured body part across both youth and professional levels, with thigh strains topping the list ahead of ankle sprains and knee injuries.
Why Hamstring Strains Are So Common
Soccer demands repeated sprinting, sudden deceleration, and explosive kicking, all of which place enormous stress on the muscles running down the back of the thigh. The injury typically happens during two specific moments in a sprint: the late swing phase, when your leg is extending forward just before your foot hits the ground, and the late stance phase, as you push off to propel yourself forward. In both cases, the hamstring is lengthening while simultaneously trying to contract, a combination that can overwhelm the muscle fibers.
This type of strain is driven more by excessive stretching under load than by raw force. How fast the muscle is being lengthened and how long it’s been activated before the stretch both influence severity. That’s why hamstring injuries range from minor tightness that sidelines a player for a week to complete tears requiring months of rehabilitation.
The trend is moving in the wrong direction. A long-running study of elite European clubs found that training hamstring injury rates increased by about 6.7% per year between the 2014/15 and 2021/22 seasons. Match hamstring injury rates rose by roughly 3.9% annually over the same period. Denser match schedules, shorter recovery windows, and higher game intensity are likely contributors.
Ankle Sprains: The Second Major Risk
The ankle is the third most frequently injured area in professional soccer (behind the knee and muscle injuries overall), accounting for 10% to 18% of all reported injuries. Among those ankle injuries, ligament damage makes up 62% to 69% of cases, and three out of four ligament injuries affect the outside of the ankle, what’s known as a lateral ankle sprain.
These sprains happen when the foot rolls inward during a tackle, a landing, or a sudden direction change. They’re often dismissed as minor, but the numbers suggest otherwise. The recurrence rate for lateral ankle sprains in professional players sits around 25%, meaning one in four players who sprain their ankle will do it again. Incomplete rehabilitation and lingering instability are the usual reasons a sprain keeps coming back.
Knee Injuries and the ACL Gender Gap
Knee injuries, particularly tears of the anterior cruciate ligament (ACL), are less frequent than hamstring strains or ankle sprains but far more severe. An ACL tear typically requires surgery and six to nine months of recovery, often longer before a player feels fully confident again.
Female soccer players face more than twice the risk of an ACL tear compared to males. Research from Washington University found that male players activate certain hip and leg muscles more during kicking motions, providing greater knee stability. Female players tend to show decreased activation of key hip muscles on the supporting leg, the one planted on the ground during a kick, which may leave that knee more vulnerable to giving way during non-contact movements like cutting or landing from a jump.
There’s also a notable difference in which leg gets hurt. Among male players who suffered non-contact injuries, 74% occurred in the dominant kicking leg. Among female players, only 32% were on the dominant side, with the majority affecting the support leg instead. This pattern reinforces that the mechanics of how each leg stabilizes and absorbs force play a significant role.
Concussions in Soccer
Soccer ranks among the youth sports with the highest concussion rates. The CDC reports that concussions in high school soccer most commonly occur during heading, though the injury usually results from player-to-player collisions rather than the ball itself. About one in three concussions among female high school players happens during heading, compared to about one in four among males.
These numbers have driven rule changes at the youth level, including restrictions on heading for younger age groups in the United States. At the professional level, concussion protocols and substitution rules continue to evolve as the sport takes head injuries more seriously.
How Youth and Professional Injuries Compare
The overall pattern of injuries is remarkably consistent across age groups. Strains, sprains, and contusions are the three most common injury types for both youth academy players and professional adults, and the upper leg is the most frequently injured location in both groups. Matches carry far more risk than training at every level. Professional players are 3.3 to 15.3 times more likely to get injured in a match than in training, while youth players see a 2.3 to 4.9 times higher risk during games.
Youth players actually report higher training injury rates (3.7 to 11.1 injuries per 1,000 hours) than professionals (1.4 to 5.8 per 1,000 hours), possibly because younger athletes are still developing coordination, strength, and movement patterns that protect against injury. On the other hand, professional adults have significantly higher reinjury rates, ranging from 9% to 30%, reflecting the cumulative toll of years of competition and the pressure to return from injuries quickly.
What Actually Reduces Injury Risk
The most studied prevention tool in soccer is a structured warm-up program developed by FIFA, known as the 11+. It takes about 20 minutes and combines running exercises, bodyweight strength work, and balance drills designed to improve how players control their hips, knees, and ankles during dynamic movements.
Teams that use it consistently see roughly 30% fewer injuries overall. For severe injuries like ACL tears, the reduction reaches about 50%. Players in intervention groups also lost 40% fewer days to injury compared to those following standard warm-ups, and they accumulated more training hours over the course of a season. The key word is consistency: teams with moderate to high compliance saw an 11% reduction in the total number of injured players and an average of six fewer days off per injury.
Beyond structured warm-ups, the basics matter. Eccentric hamstring exercises (where you slowly lower your body weight to load the muscle while it lengthens) are one of the most effective ways to protect against hamstring strains specifically. Proper rehabilitation after ankle sprains, including balance and proprioception work, cuts into that 25% recurrence rate. And for female players, neuromuscular training that targets hip strength and landing mechanics addresses the specific muscle activation patterns linked to ACL risk.
