Best Hand Position in Chaturanga? Torque, Moment Arms, & Levers | Yoga Anatomy Lesson

[@Myshoelace]

I’ve been learning so much from your videos! Thank you 🙏🏼 😊

[@ShapeshiftWellness]

Fantastic! I’m happy they’ve helped!

[@monicaresto1995]

I really appreciate your final diagrams depicting some of the forces involved in the chaturanga dandasana position with different hand placements. It reminds me of statics free body diagrams (I have a background in civil engineering). Cheers, and thanks for all of this great experience- and science-derived info.

[@ShapeshiftWellness]

Thank you! I'm really glad to hear that it checks out with your engineering background. I do my best to properly represent the science behind movement, exercise, and health in general but there's SO much to learn and understand! If you ever have input, feel encouraged to add your thoughts!

Great detailed content not found easily. I've watched your mini series of the shoulder, but you just mentioned slightly the winging scapula. Are there any more cues other than pushing hard the floor, to mantain my scapula depressed and retracted in chaturanga? My shoulders aren't liking it and feel I'm overcompensating with my trapezius. Thank you, please keep it up

So I really suck at grasping physics but I THINK I followed that, which is amazing in itself! haha

[@ShapeshiftWellness]

Physics is kind of tricky! It's fun to think about though.

[@IAsteve]

C seems to the hardest since it's so far away from my COM, B is the easiest, A is a little bit harder than B but not by much. I'm also not an expert in physics, but I'm guessing that the torque applied on a joint is not linear to the length of the moment arm?

[@ShapeshiftWellness]

It’s linear, torque is just the force x moment arm.

[@IAsteve]

Idk, whatever the reason, C is definitely hardest for me and it's not even close

[@ShapeshiftWellness]

@@IAsteve I 100% agree!

I hurt my shoulder doing option 1

This channel should be called SMART ARSE

ConstructiveMinds100 I can’t tell if that’s a compliment or an insult? Or a little of both 🤣

Natural alignment means like how animals use their limbs, which is done in a way where arms are used for propelling body forwards, meaning arms push body forward ala if doing decline benchpress. Look anatomy of cat skeletons or models and see that they never fully strech their arms to outermost extentsion or outmost extreme extention

[@MrCarstennielsen]

If a cat fully strech arms or forelegs when body is horisontal like pushups or animalmoves, then that will make a kind of internal rotation of shoulder I believe, it is kind of the same problem people find when they are having shoulderinjuries from benchpress; The arms and hands are locked and so force shoulder unnaturally int. rotation. Animals limbs are never really fully extended or at least not at all with body or weight on them continiously without lifting the leg and so letting the arm or leg adapt to the new circumstances.

@@MrCarstennielsen I see what your doing here... Taking the context out of biped and using quadruped... Sneaky

[@ShapeshiftWellness]

carsten nielsen Why are you using cat anatomy to judge human motion? Cats walk on all fours. We don’t. Our arms have a completely different function because our bones and muscles have a completely different shape. That’s a totally unrelated comparison.

[@MrCarstennielsen]

@@ShapeshiftWellness catanatomy is used for medical education and we have identical spinalstructure and our shoulders are meant to have the scapulajoint-face to project forward like cats and use the acromion to guide this process.

[@MrCarstennielsen]

@@klikram9095 I do not know what you see, but im pretty sure its an illusion created in your mind.

[@MrCarstennielsen]

Interesting but it seems like you do not consider natural alignment and that the body is pushing the body for what by extending the body forward and so pushing the arms to the hips you seem like it's Theory only with lack of physical experience sorry

[@ShapeshiftWellness]

This video is meant to simply explain how physics is acting on the joints, so you can make informed choices about which position is best for your goals. There are many "correct" ways of doing this yoga pose. As for experience, I've practiced hatha yoga regularly for nearly a decade. I have plenty of experience with it, thank you.

[@Megh2D]

I would be interested to hear more about what carston means as "natural alignment." Is that for every body? As a body with an old rotator cuff injury, my "natural alignment" at this point in my life is not at all the same as it was prior to that injury. Considering force on my shoulder, options available in a range of comfort and safety are waaaay more helpful to me than relying on my "natural alignment."

[@Megh2D]

... literally just got to the point of the video where Anthony mentions injury in relation to these things, so I'm just a happy redundancy

[@ShapeshiftWellness]

@megh2d - Nailed it!
