Is it actually good for you?

Squatting is widely accepted as one of the greatest movements in strength training and, among those who are more versed in the iron game, it is also widely accepted that not squatting past parallel makes you a total ninny.

That is…until Eric Cressey wrote this article HERE.

In essence, what Eric was saying was that if you can’t squat past parallel without going into lumbar flexion that perhaps you should avoid it.  Instead, it might be better for you to squat to a depth that prevents lumbar flexion (possibly by doing a box squat) and thereby reduce your injury risk.

In fact, the current thinking in the strength training community as a whole seems to be that loading the lumbar spine under flexion is a bad idea in any circumstance.  The general consensus is that when the spine is flexed there is nothing to resist the anterior shear forces produced by the load and the risk of injury is high.  I actually subscribe to this theory myself.

However, I recently stumbled across the little tidbit of information below that has given me pause.  That is not to say that I’m sold on the idea or that I’ll be changing my methods any time soon, but it is important to keep an open mind.  After all, you can pretty much find information to support whatever viewpoint you have.  Reading information that is challenges your viewpoint is probably going to teach you more than the stuff that agrees with it.

While reading through Functional Anatomy of the Spine by Middleditch and Oliver I stumbled across this point:

“Posterior rotation of the pelvis causes an increase in flexion at the lumbosacral junction and hence increases tension in the thoracolumbar fascia. Lumbar spine flexion also passively increases tension in the thoracolumbar fascia. Competitive weightlifters may flex or ’round out’ the lumbosacral area and it is suggested that this affords some protection by increasing tension in the thoracolumbar fascia and posterior ligamentous structures, thereby contributing to stability in the low lumbar area.”

They even go so far as to say that this effect might help to reduce anterior shear forces produced by flexion.

As I said earlier, I’m not totally sold on that idea and I’m definitely not about to start suggesting that you should squat with a flexed spine, but there is a point to take home.  If the thoracolumbar fascia can contribute to spinal stability, then contracting the lats (which attach to the fascia) while squatting could theoretically pull the fascia taut and reduce anterior sheer.

Just some food for thought.
