Random Thoughts from a Restless Mind

Dear Coaches and Parents,

For more than 30 years I have had the good fortune to be a volunteer assistant coach for boys and young men playing football, basketball, and lacrosse, sports I played in high school and/or college. In this capacity I became very familiar with the particular dangers of concussions suffered while playing these contact sports. Indeed, one of my sons suffered a severe concussion as a high school lacrosse player, effectively ending his competitive career. I applaud the recent efforts being made at all levels of competition, especially in the area of gratuitous headshots in football, lacrosse, and hockey.

As a fitness coach for the last 10 years or so I’ve learned of another, all too common injury in sports, one that is disproportionally concentrated in the younger athletes: ACL tears in girls and young women. There is a veritable epidemic of ACL injuries in soccer, basketball, and volleyball. Girls are 4-6X more likely to tear their ACL playing these sports than boys. The numbers are quite simply appalling, and yet I hear not a word about this from any media source. Girls are being felled by this injury in droves but it seems no one is talking about how to prevent it.

Can anyone tell me why that is?

It’s not like this is a new phenomenon. A brief Google search turns up academic articles published in 1999. It’s also not as if these injuries are only of historical importance. The daughter of a friend was the third girl playing the same position for the same U17 soccer team for the same coach to suffer a non-contact ACL tear in 2015. Nor were they the only girls on that team so afflicted. When asked what changes had been made by the team or the coach in response to these injuries my friend shook his head. Crickets.

Can anyone tell me how this is OK?

The answer, of course, is that it is not OK. Not even a little bit. The causes underlying the increased risk to suffer an ACL tear in which a female athlete does not come into contact with another player are relatively well known. Studies have been done examining the way girls jump and land. As it turns out, girls tend to change direction and land with an outstretched, straight leg. Boys, on the other hand, do so with a flexed leg, reducing tension on the ACL.

If you watch girls running you can’t help but be struck by the valgus position of the knee when their foot lands on the ground; the knee is markedly inside the foot.  Girls tend to have stronger anterior muscles and therefore tend to be quad-dominant runners. They pull their upper leg forward through the contraction of the thigh muscles. Boys, on the other hand, are posterior chain-dominant runners, pulling their legs up through the contraction of their glutes and hamstrings. Without a strong posterior chain to counteract the effect of the quadriceps, the ACL is again under increased tension, magnifying the risk caused by knee position.

We know why the injuries occur, and as it turns out we also know how to prevent them, or at least reduce their frequency: teach young female athletes safer movement patterns, and put them in strength and conditioning programs that specifically train their posterior chain. If you see this type of training you will recognize it immediately: it’s how we train boys.

Can anyone explain to me why this is not occurring with young female athletes right now?

Even at the highest level of women’s sports we still see non-contact ACL injuries. For example, in 2011, 6 of the 21 members of the U.S. Women’s National Soccer Team had suffered an ACL tear at one point in their careers. However, in more recent years there has been a decrease in these injuries at the professional level because teams are training their female athletes in better neuromuscular recruitment patterns, which creates sounder movement. Athletes are doing strength and conditioning programs that emphasize strengthening their glutes and hamstrings. Hence, we are seeing dramatically fewer ACL tears at the highest levels of women’s sports. There is no way to justify not doing the same thing for girls early in their careers.

Proven templates already exist to do just this. Simply utilizing the off-the-shelf PEP program of stretching and plyometrics has demonstrated meaningful decreases in the incidence of ACL tears. Rather than use such a basic program when it comes to high quality movement patterns, why not look to someone like San Francisco’s Dr. Kelly Starrett? The founder of Mobility WOD and author of “The Supple Leopard”, Dr. Starrett is a consultant to dozens of collegiate athletic departments. He recently took over training for an elite 150-member girls volleyball program with the specific aim of reducing ACL injuries in those athletes. His teachings on proper movement mechanics are peerless, as a quick perusal of his book will attest. Perhaps we should be looking at what he is doing.

Jeff and Mikki Martin have been training kids in Southern California, the epicenter of youth soccer, for well over a decade. Their protocols include meticulous attention to the type of mechanics taught by Kelly Starrett and emphasize the importance of strengthening the posterior chain beginning around age 10. As the developers of the original CrossFit Kids program and more recently founders of The Brand X Method™, they have trained hundreds of young girls who play soccer without a single one of their athletes suffering an ACL injury while under their care. They arguably have the longest track record of successfully and safely training youngsters. Perhaps we should be looking at what they are doing.

One thing is for sure: it is not OK to continue with the status quo. Simply doing what you have always done is nothing less than condemning a high percentage of your girls and young women to suffering an ACL tear and all that goes along with it. The nature of the sports in which we see an epidemic of concussions is such that the only way to prevent them is not to play those sports. This is not the case with non-contact ACL tears in soccer, basketball, volleyball and other sports played by girls. Prevention is possible through the institution of training programs that emphasize the teaching of new, safer movement patterns, as well as strengthening the muscles of the posterior chain.

I’d like to propose a 3-part solution to this problem. First, we would like to offer training to coaches in how to teach better basic movement patterns. One of the most fundamental goals for those of us who utilize The Brand X Method ™ to train kids and teens is to create a cadre of coaches who can do this. We hope that this can become a core part of in-season team training. Secondly, we wish to make available our coaches, and coaches who share our concerns and philosophy, to train your athletes to have a stronger posterior chain. The data supporting the inclusion of weighted squats, deadlifts, and power cleans both in season and out of season is compelling. Our coaches are experts in teaching the proper mechanics involved, and our athletes progress in a safe and measured fashion.

Lastly, the data supporting the inclusion of full-body functional movements executed at relatively high intensity is equally compelling when it comes to not only injury prevention, but also in developing stronger, faster, more durable athletes. The Brand X Method ™ is a proven program that emphasizes proper mechanics and safety. It is the latest version of a program that has been creating highly athletic youngsters and teens for more than 10 years. This type of physical fitness directly translates to more capable and confident athletes in all of the sports mentioned. At CrossFit Bingo our Alpha X Youth Athletics program is available to train your athletes all year round, either individually or in team settings.

It’s time we all start talking about these non-contact ACL injuries in girls’ sports, just like we have been talking about concussions in boys’ sports. Parents should be asking what is being done on behalf of their daughters. Coaches should be committed to stopping the epidemic of non-contact ACL injuries in their female athletes.

We can help.
