Another little blurb from a John Berardi article:
Myth #3: It Is Unsafe To Squat, Deadlift, Bench Press, Or Pick Your Nose Without A Lifting Belt
It has been brought to my attention that certain companies require their employees with labor-intensive positions to wear back braces/lifting belts.
When I run a company some day, whether we do labor intensive work or not, I plan to have my employees use standard issue bone files to grind away at each other’s spines.
Am I a monster? Maybe. But I’m being facetious in order to make a point. The point is that two scenarios above are about equally beneficial to overall back health!
You see, every man, woman and child on this planet has been given a lifting belt. That’s right; you arrived on this planet with one that was factory installed! It’s called a transversus abdominus or TVA. Unfortunately, most people haven’t used theirs since they were on the merry-go-round as a child. This muscle, the TVA, wraps all the way around your midsection like a corset, attaching to the thoracolumbar fascia, which then connects to your lumbar vertebrae or “lower back”. When contracted, it pulls at both sides of your spine creating something called hoop tension, which then sets off a waterfall effect of contracting the deep musculature of your torso. Once this has happened, your spine is rigid and fully protected, and your pelvic floor muscles contract, transferring stability to your lower body. Simply by contracting this muscle, you go from a noodle to a tank.
Now, since our TVA likes its very important job, it takes great offense to our silly attempts at replacing it. Therefore when we put on some sort of brace or lifting belt, our TVA decides to relax, robbing us of stability and spinal rigidity. (This has to do with the relaxation of our abdominals). Therefore, not only is wearing a belt unecessary, it can cause your nervous system to chronically inhibit your built in protective musculature. This can lead to spinal degeneration!
There, I said it! Wearing a belt can be worse for your back than not wearing one! So, if you take heed and decide that I may know a thing or two about back health, get rid of your belt. Or better yet, give it to one of your enemies. But do so gradually. If you’ve been wearing a belt for years, gradually taper yourself off of it, and get used to using your own muscles. Have someone knowledgeable teach you how to contract your TVA and you will be significantly better off.
