Causes of Knee Valgus

14 01 2013

Well I was in the middle of writing a post on the methods I employ to speed recovery between training sets and also increase general endurance.
Half way through I realised I don’t have the video footage I needed and my camera is in the gym. My bad, I’m stoopid.

So I guess you’ll just have to check in later in the week for that one!

This did lead to a small issue though….

What the hell do I write about for this morning?

And then I come across THIS from one of the biggest brains in the Strength & Conditioning industry, Mr Bret Contreras.
Whatever Brett writes is worth a read. He takes the science research, goes through it with a fine toothcomb and then presents it to us mere luddites in a manner we can almost understand!

The article I’m referring to today is from his Strength & Conditioning Research journal, which is an excellent resource for all coaches.
This particular one talks about a thing called Knee Valgus.

What is knee valgus?

It’s where your knees pull together, giving that knock kneed look.
It’s very common when people squat, even more common in the female population.

So what’s wrong with knee valgus?

It can put an excessive amount of stress on the Anterior Cruciate Ligament (ACL). Which obviously aint good.

So how about do we go about fixing it?

That depends on the cause.
As Brets post states, some potential causes (which are also the ones I always look for)

decreased gluteal activation or strength, increased hip-adductor activation and decreased ankle-dorsiflexion range of motion (ROM)

Makes sense. For the knee to move into a valgus position the hip must rotate internally, in orther words our external rotators aren’t working right and our internal rotators (Adductors, Hip Flexors) are doing overtime. It may also be that the arch of the foot has started to collapse leading to the ankle tracking poorly.
It all follows the alternating joint theory nice and neatly, where the ankle should be mobile, the knee stable and the hips mobile. An problem at one joint means another must take up the slack by becoming more/less mobile/stable.

I don’t think any one symptom occurs independently but they have a cascade effect, either from the top down or the bottom up.

The study in Brets post talks about the Gastocnemius (the fat part of the calf) is mentioned as being over active and causing problems for the Anterior Tibialis on the front of the shin. Something I’d never considered.
Could this also help explain shin splints?
Maybe.

Needless to say I’m going to start paying more attention to peoples gastroc flexibility and have them work more ankle mobilisation as soon as I see any valgus during squat movements.
I use two ankle mobilisations already with the guys, the primary drill being the Wall Ankle Mobilisation (catchy title, eh?)

Here’s top coach Eric Cressy explaining how it works:

It’s one of the drills I teach during the Squatting section in my Bodyweight Workshop.
The next workshop is coming up on February 23rd at Galway Kettlebells.
This is filling fast, so if you want to learn:

- Joint mobilisation for the whole body
- In depth examination of the Push Up and Squat movements, with progressions for more advanced practitioners.
- Martial Arts & Animal movements for strength, conditioning and mobility
- More, in fact as much as we can fit in!

Drop me an email to book your spot.

Glute Strength and Hamstring Injury

24 08 2011

"The Hips Don't Lie" and who are we to argue?

Hips have been a hot topic around here at the moment.
An Fear Rua, a major website covering all the top information in the GAA (Gaelic Amateur Athletics, Ireland’s indigenous sport) have published an article I recently wrote talking about hip strength for injury prevention in their athletes.

In the article I talk about the importance of strengthening the hip in order to prevent the most commonly occurring off the ball injuries, the knee.
Today’s post isn’t going to be a rehash of the article, but does support it.

I’ve a soccer playing athlete recently joined me. He’s been complaining of hamstring injury and chronic tightness in the hammies for the last few years. Physio’s that he;s seen have told him to rest, and when he does he gets some respite. However as soon as he’s back on the ball, his injury rears its ugly head and he’s lucky to see out the season.

By chance he stumbled across Wild Geese and within a few weeks we’ve gone a long way to reduce his pain and loosen his hamstrings.
How?
Not with stretching, but with strength. Not strength in the hamstrings themselves but int he glutes.

I introduced him to a the Bridge and the Hip Thrust exercise. I have to tip my hat to Bret “the Glute Guy” Contreras for relaunching these drills into the weight training psyche.
The following video shows how we integrate the hip thrust into a training program. in this case it’s a contrast set.

We take the Hip thrust for 5 reps, rest 30- 45 seconds then Swing the kettlebell for 8 reps in each hand. this is repeated for 4-6 sets.

The first exercise targets the glutes directly, the second integrates them into the whole.
End result, stronger, more efficient hips, which will allow the hamstrings to relax and return to their resting length.

Here’s the video:

As always, use common sense when trying out any new exercise or protocol.
