Hello. I am Tom. And I am Michael. And in the present day within the tutorial, what we’re gonna do is take a look at the place of the scapula. And for that, we’re gonna use the ideas and the ideas from spiral dynamic. In spiral dynamic, they contemplate the shoulder the scapula, a transmission unit, and it transmits the drive of the coordination unit of the arms to the trunk and from the trunk to the arms. As a way to do that, the scapula must be in the correct place. That will be useful.
So this once we take a look at the scapula and there it’s. We’re the Scapulak is creating its stability by staying on prime of our rib cage. Due to that, it should transfer and will transfer with the rib cage once we go into flexion and once we go into extension. So let’s take a look at how that ought to observe the backbone. So when the backbone is in its elongated place, which You may, if you do not know what elongation is, search for our earlier tutorial about elongation of the backbone. When that’s related, the scapula sits proper on prime of it, and it creates, like I mentioned, the, stability from being related to that rib cage.
So when Michael begins to roll ahead and we’ve flexion, it does transfer with the backbone. What it shouldn’t do is when he begins to roll ahead and the shopper begins to lose that connection and the shoulder form of like begins to roll in and slide ahead. That’s not staying on prime of it. It ought to keep again and transfer with the backbone. With out gliding off it as he goes ahead.
In order that’s the place it’d typically be a refined distinction, however that is what you wanna look out for as they begin shifting. So that you wanna be the rib cage with the ball? Mhmm. So once we take a look at the place of the scapula. If that is his rib cage, it sits proper on prime of it. And right here is the claffical decolor bone that’s then related to the sternum.
So that is related. That is the one half that has as a result of the arm connects over right here. So with this being related, the scapula can do 3 actions are 3 rotations on round 3 axis. The primary axis we name is the transverse axis, which works from proper to left by means of the physique. And if we observe that rotation and if we take this coracoid course of as our reference level, it rows in or ahead and backwards.
So that’s one motion that’s attainable on this scapula. Then we’ve motion across the sagittal axis. The sagittal axis goes by means of back and front of your physique. So that enables the shoulder blade to glide up and down sideways. Proper? After which we’ve the longitudinal axis, which goes straight up and down, which permits the collar bone to or the shoulder to maneuver out and in. Proper?
So, clearly, that is most likely extra motion than you’ll find in your shoulder. So now once we put all of it collectively, it permits the shoulder to maneuver what we prefer to name an inward spiral after which again to the outward spiral. So it permits us to go out and in. So let’s discover that on our personal physique. So when you Have a yoga block.
If in case you have a yoga block, you should utilize that or a pillow, and even your telephone, something that can assist. So we’re gonna simply gonna sit and sit straight, and we’re gonna fake that that is our shoulder. Proper? So the primary axis we’re speaking about is the transverse axis. So that enables our shoulder blade to go this manner and that method. So we go in or ahead and backwards. Another time.
Forwards and backwards. Then we’ve our sagittal axis from the entrance. That permits us to do that rotation. And a few folks name this the upward rotation and the downward rotation. Proper? We now have that going this manner.
Then we’ve the longitudinal axis, which works straight up and down, which permits us to do that and that. So extra just like the protraction, retraction form of movement. So now we’re gonna put all of these collectively. Wow. Thrilling. So we’re gonna go ahead up and in, after which again down and out. That is loads of motion.
Ahead upwards and inwards, backwards, downwards, and outwards. Another time for the folks within the again. We go ahead, upwards, and inwards, backwards, downwards, and outwards. So these are what we name an inward spiral and an outward spiral as a result of it has a rotation round all three axis. On the identical time.
Now why is it vital, Michael? I do not know. Inform me. Okay. We’ll discover out why we’d like that. So if we will do all of it collectively yet another time, we will place our hand throughout, and also you place the heel of your hand in your collarbone, proper up there, and then you definately transfer your fingers over your shoulder and you discover this little bone over right here, the backbone of your scapula. So you’ll be able to attain over and discover it there.
Now what we will do, let me be over right here, when you do go this manner to allow them to see it. So you need to hand over, Which hand would you like? I do not care. Simply go over right here. There we go. So when he goes into the entrance, inward spiral and outward spiral. Now when you all do it at dwelling as effectively, what I need you to really feel is the space between the heel of your hand and your fingers. So once you maintain it, we go inward, and we go outward.
Proper? So simply try this a few instances. And I am going to really feel what occurs with that house in between your fingers and the heel of your hinge. And what we hopefully you’ll discover is as you’re going inward, there turns into much less house between these two And once we go open into the outward, there’s extra space. Proper? So there’s much less house, and there may be extra space. Now that’s going to be vital. Now this house from right here, the colour bone and the shoulder blade must be about 60 levels.
Proper? Now we perceive you are not gonna run round with a protractor in your lessons and go, I can transfer 60 levels, however it’s a No. I I do not, anyway. You may. However what we would like is that you’ve got that visible in your head, what it needs to be as a result of then you’ll be able to acknowledge it along with your purchasers and see if like, oh, that appears very brief. Now The rationale why that’s vital, you wish to be the chest once more, is what we noticed, what you seen was like once we go inward, This comes collectively, these 2. And once we go outward, these 2 transfer away from one another. And particularly once we are weight bearing, that turns into a problem. So if we’re standing are you able to maintain that for a sec? And we’ve the arm hanging down.
It is okay. It is advantageous. However now when we’re going to go weight bearing, And we’ve this hand on the ground. What we see is that the load that Mike was speaking about of the bottom drive is being divided equally, if we take a look at extra for the entrance, between this a part of the backbone and the scapula. So it turns into like virtually like a tripod over there. Now and the load is evenly divided.
Now see what occurs if this goes in. I haven’t got a fair distribution of or quadruped place, and the shoulders are actually ahead. They do not have the drive equally divided and distributed over. Or if are you able to go into your fingers and knees and grasp your shoulders? Properly, I do know you’ll be able to. Oh, I do know.
I I grasp very well. If he begins to wing, we’ve the identical downside. It turns into brief, and the drive isn’t equally carried by means of the physique. You need that? So when Michael was speaking about, if he rounds an excessive amount of and it goes in, it turns into brief, and it doesn’t distribute equally. If he goes again, however now he begins to wing.
So we go this manner, it additionally turns into an issue, proper? Or typically they go this manner. Off. So it is all about ensuring that that compelled this distribution that Michael was speaking about between the coordination unit of the arm and the coordination unit of the backbone is absorbed by means of this transmission unit. And if it is within the outward spiral, this open place, that occurs a lot safer and extra even for the physique to soak up. So once we are doing that, we’d like sure muscle mass that must be robust and sure muscle mass that must be lengthened.
So, I feel it is this manner simpler. So the muscle mass that create that stability are the ascending components of the trapezius. So they arrive from the again from the underside and assist shifting this shoulder blade down into the place. The opposite one is the decrease a part of the serratus anterior. They transfer this level into the rib cage.
Now what you’ll be able to see is in when this shoulder blade goes again into the correct place, this opens up loads. And particularly with people who find themselves very tight within the entrance, particularly the pectoralis minor, that is hooked up to the Coricoid course of right here and strikes down right here to the highest ribs. That may actually pull this brief and creates an issue, proper? So once you work with people who find themselves very a lot in that place, thanks. The lengthening or releasing of the pectoralis minor is one thing that you really want to bear in mind, and within the again, the strengthening of the ascending fibers or the underside a part of the trapezius and the low decrease a part of the serratus anterior. Now We hope this clarified a bit of little bit of the place the place of the scapula needs to be.
If in case you have any questions, write it down within the feedback. And likewise, if you need any concepts about workouts for this scapula, there is a hyperlink to our exercise, that each one offers with this calculator. Hope this was useful.
