Are you in training for something? Maybe getting ready for a dream vacation or a competitive run?
Or maybe you’ve noticed that you’ve started to limit what you do: you’re not walking as far, or you’re carrying less weight. And you’d like to turn that trajectory around.
Russ Mitchell wrote an excellent blog about training smart and limiting injury with the Feldenkrais Method® which you’ll want to read. His explanation of the function of our different kinds of muscles makes it simple to understand: keep reading for an excerpt from his blog.
Postural Vs. Phasic Muscles
“You have two basic types of muscles: postural muscles and phasic muscles. If you cook a turkey, the postural muscles are the “dark meat,” and the phasic muscles the “white meat.” (Look at where that meat sits on a turkey… it becomes pretty obvious why each is where they are pretty quickly!)
The postural, aka “slow twitch” muscles are weaker — dramatically weaker — than the “fast twitch” phasic muscles. But “fast twitch” doesn’t mean “faster to execute.” The “Twitch” in these fibers’ names is in regard to how quickly they exhaust. “Slow twitch” fibers are called that because they may not be strong, but they’re long-lasting, and they come into action before the phasic muscles do. . . .
Easy example: postural muscles work all the time to counter-act gravity, mostly without any conscious awareness on your part. But ever accidentally exhausted the muscles in your jaw? Wasn’t that fun?
So why does this matter, and where does the Feldenkrais Method come in? Well, put simply, for you to avoid injuring your joints with explosive movements, you need to be able to get yourself into an alignment where you can muster your awesome athletic and artistic forces properly. The slow-twitch fibers are actually the first to be recruited once you have an idea of the movement you intend to do, in order to get your skeleton into position to “do the thing” properly so that you can jump, throw, swing, twist, dive, etcetera, easily, fluidly, and without strain.
Otherwise, even if you’re not in a squat rack, performing these activities with bad alignment tears up your body just as surely as would trying to perform a heavy squat or deadlift while standing knock-kneed. Anthony Bourdain, before he passed, used to lament the long-term damage he’d done to his hand just using a whisk. And any string musician can tell you what “bad form” will do to your wrists and elbows.”
