Sam Snow just posted an article on preventing injuries for US Youth Soccer written by Movement Solutions. Sam’s Blog is a bi-weekly addition to the US Youth Soccer Blog. Sam Snow is the Coaching Director for US Youth Soccer. We are excited to continue our relationship with spreading injury prevention information through US Youth Soccer. Check out an excerpt of the article below with the full article and exercise videos available at the link below:
The ACL and Injury
Anterior cruciate ligament (ACL) injury rates are high in youth soccer and have been increasing the past 20 years. These injuries have serious effects on the lives of players, teams and coaches. The ACL connects the thigh bone to the shin bone, helping to prevent twisting and bending of the leg. However, if too much twisting or bending happens at the leg, injury can occur even if there is no contact. In fact, non-contact injuries are responsible for over 70 percent of injuries.
Trying to figure out what causes these injuries can be confusing. ACL injuries are often blamed on factors that coaches and players cannot control. These factors can be bone structure, hormones or even gender. What is usually neglected is a key reason for injury that we can control: misaligned movement.
Misaligned Movement Can Lead to Injury
What is misaligned movement? The human body is like a machine similar to a car. When a car’s alignment is off it begins to have wear and tear, perform poorly and then ultimately it will break down. Our bodies are no different. If the body’s alignment is off during athletic movement, the body can experience wear and tear, perform poorly and eventually get hurt. Just like we are trained to operate a car skillfully, soccer players need to be trained to move properly. This starts with correcting misaligned movement patterns.
It is important for coaches to know that just like each player has different skills and abilities, each player has a different way of moving. Certain players may even demonstrate misaligned movement.
There are many types of misaligned movements. Coaches should watch out for a common misaligned movement that leads to ACL injury: the knee collapsing inward (image 1). Research shows that players who suffered an ACL tear demonstrate a greater amount of knee collapse. The knee can collapse inwards during fundamental movements in soccer. These movements include planting, decelerating and changing directions at high speeds.
