Understanding the Risks for Concussions in Soccer

July 09, 2015

This past weekend, millions of people across the world watched as the United States won the 2015 Women’s World Cup in a thrilling, 5-2 victory over Japan. It was a great moment for women’s soccer, which has swelled in popularity in recent decades.

 But in the United States women’s semifinal match against Germany, the athleticism of the sport—and its real risks for serious injury—became all too evident. Midfielder Morgan Brian collided head first with German player, Alexandra Popp, as she tried to head the ball. Popp bled from her head and Brian laid on the turf for several minutes in pain. Soccer officials said neither player showed signs of a concussion, so they were allowed to continue playing.

The incident highlights the dangers of serious head injuries in soccer, and the fact that more needs to be done to reduce the risk of these injuries. Members of the celebrated 1999 U.S. women’s team that won the World Cup already are leading the charge in this area. Cindy Parlow Cone, a member of the 1999 team and one of the best headers in U.S. soccer history, recently told HBO’s Real Sports that she continues to suffer from headaches, jaw pain and fatigue from all those years of heading the ball. She and many of her 1999 teammates are pushing the sport to ban heading for kids under age 14.

As we celebrate the impressive accomplishment of the U.S. Women’s National Team, we should understand that being a champion has its costs. We often hear about concussions in football, but soccer also comes with its own risk of serious head injuries.

Nearly 3.8 million concussions occur each year in the United States, and between 5-10 percent of athletes will experience a concussion during a sports season, according to the Sports Concussion Institute.

Despite the increased attention given to concussions, many people are still confused about what they actually are and when to seek treatment. About 50 percent of concussions still go unreported, so it’s crucial that parents, players, and coaches alike understand what this condition is and how serious it can be.

Concussions in Soccer

During a concussion, the brain is injured not necessarily in substance, such as with a bruise to the skin, but rather in function.  A concussion is a traumatic, microscopic injury that causes a disturbance in normal brain activity. It is this disturbance of normal brain activity that causes the symptoms of concussion.

As a contact sport, soccer poses a significant risk for concussions and head injuries. The head is at risk of contact with the ground during a fall or with another player’s head, elbow, knee, or foot. The greatest chance for impact in soccer comes during contested headers and set plays, such as corner kicks, where many players are in close contact.  Concussions can also occur without direct impact to the head. A hard hit to body could cause the head and neck to move quickly with a whiplash effect.

The brain is a semi-solid material, like Jello or tofu.  It is surrounded by a layer of fluid to cushion it inside the hard skull, which is there to protect it.  Take the example of a player who attempts to head a ball, but instead comes in contact with the knee of his opponent. In this case, the other player’s knee hits our player’s skull, which then hits the brain.  In the whiplash example, the brain and skull are moving forward as a unit. If a hard blow happens to the body, the skull stops moving because it is attached to the body, but the brain keeps moving forward until it hits the skull.  This is how a concussion can occur without a direct blow to the head.

If the force of the impact is enough to injure the brain cells, a pathologic process begins that affects the lining of the brain cells.  The lining becomes leaking, allowing molecules to drift back and forth inappropriately. Because of this, the nerve cells cannot function properly or efficiently.

When this happens, a player will begin to experience symptoms like headaches, fatigue, nausea, mood changes, lack of coordination, slurred speech, and sensitivity to light and sound. Contrary to popular belief, you don’t have to pass out to have a concussion (in fact, this happens in very few cases). Concussion symptoms will vary from person to person, so all symptoms and unusual behaviors following a blow to the head should be taken seriously.

Minimizing the Risk of Concussions

Concussions are a real danger whenever a soccer player hits the field. So, what should you do if you’re a competitive athlete—or better yet a concerned parent or spouse? Many sports leagues, including Major League Soccer and U.S. Soccer, have implemented concussion evaluation and management protocols. If you are unsure of whether your local league has put similar measures into place, talk to the coach or sports director about how they handle player concussions.  We also can minimize the risk of concussions in soccer players by teaching safe play habits.  When a player knows the rules of the sport, this helps to stop preventable collisions.

Addressing a Concussion

Even with the proper precautions, concussions still happen. Sports are unpredictable and athletes cannot anticipate or always protect themselves from impact that could lead to a concussion. If you’ve experienced a head impact and don’t feel right, tell your coach. Teammates also should keep an eye on one another and educate themselves about concussion symptoms. It’s especially important to do this in youth soccer because young brains are more sensitive to the effects of a concussion, and younger athletes also have longer cognitive recovery times.

If you have any signs or symptoms of a concussion, you should never return to sports or recreational activities on the same day. Take time to heal, and only return to your normal routine after a doctor trained in treated concussions has evaluated you. Following these steps will protect your brain and reduce your risk of more serious, long-term health issues.
