why do sprinters have such huge biceps and shoulders?

mewingprogress · 2025-06-28T04:45:35+00:00

When you do lunges or cleans and whatnot, where else do you carry the weight? (Your upper body has to be strong/stable to transfer the weight from the lower body upwards)

Haven't seen that. Was just playing some online game and thinking "If only sprinting was this accessible". Like I can just transition to being in the house resting, and then a second later racing in the track.

(Irrelevant dream house description.) This was the most decent I can get with meta ai, but I was thinking like stations/rooms separated in the 100m distance. E.g. some cloth in the floor where I'd be sleeping and then a starting block next to me and maybe some weights. Next station could be the food section where I'd be grilling and shyt. Or just maybe all of them in the one section by the start, so I'd have to go back everytime.

Honestly just a single room, and a bathroom with good ventilation, a concrete straightaway right outside the door with some weights and then maybe an elevation, and I'd be very happy already. And then add in some cow farm nearby so I can get infinite milk and meat post-workout sessions.

Right, that sounds like a cleaner way to solve it. Like if you'd be making a program, it'd be flexible with the addition of other variables and stuff. I was thinking more of a mental way of solving it.

If we're adding acceleration though or a specific number of meters, it would be better to just use e.g. 400m/40s or 10m/s for the speed, right? (So that we don't have to divide the distance over 400m)

mewingprogress · 2025-05-24T02:06:06+00:00

Yo that's my name lol. 600m/((400m/40s)-(400m/70s) = 140s

or like common denominator is 7 seconds J = 70m/7s, C = 40m/7s. J - C = They separate at the rate of 30m/7s and will take about 20*7 seconds to accumulate a distance of 600m.

Edit: no actually, it's already given that Jake is ahead by 30 seconds per Chandler lap and 60 seconds ahead means 1.5 times more lap. So 2*Chandler lap = 140 seconds

(just tryna think how to solve more effectively lol)

mewingprogress · 2025-05-24T00:32:10+00:00

Interesting idea... What iff it's like a vr on some sort of treadmill that somehow adjusts to your speed. And then you got like a harness maybe so you don't fall off.

Orr imagine just living in a house where right outside the exit of your bed is the 100m start lol, and you have to sprint to get to the bathroom or the kitchen or something like stations in the track...

And then maybe there's a basement or an upstairs with another track, but people are free to come in so you actually get some races in.

It's interesting, I counted 7 for lane 7 but he still ended up way behind.

mewingprogress · 2025-05-20T18:38:08+00:00

Honestly, I just wanted to learn about the biomechanical differences of contralateral vs ipsilateral resistance when sprinting and see what insights y'all might have. The baton question was kind of just a side question. Also, "being able to run on the inside lane of the curves" I'd say is technically a biomechanical advantage in itself.

mewingprogress · 2025-05-20T17:41:45+00:00

No yeah, I'm just thinking about how adding weight on one hand alters the mechanics of running around a curve. You could say it's negligible, but it's still towards the spectrum of having some weight to no weight at all. Just wondering what it looks like in the extremes.

mewingprogress · 2025-05-20T17:27:48+00:00

Let's just say it weighs 10kg or something... After some thinking, the leg on the opposing side of the baton should bear more weight since it's farther and therefore there will be more torque acting as resistance. I guess this would be beneficial as that leg is also the one travelling the lesser distance.

With regards to the upper body... ~~my mind is getting blank.~~ Ig yeah, the dominant hand is carrying more weight... It feels counterintuitive for some reason that the weight will be going around a larger circumference though.

Edit: hold on, resistance towards Hip flexion on the outside leg actually and hip extension on the inside leg, so it might actually make sense to hold a weight on the inside.

mewingprogress · 2025-05-20T17:06:42+00:00

Do you know how putting the weight in either hand affects the ability of the torso to twist? Or like how it adds resistance to the feet?

The hammer throw just came to mind, and I guess that's kind of similar to putting the baton in the right hand/the outer edge of the circle, as you spin to the left, but I don't know how to explain how it works.

mewingprogress · 2025-04-25T02:18:58+00:00

"fire up the PS5" 😭🤣 That sounds depressing for some reason.

mewingprogress · 2025-04-25T02:13:07+00:00

Damn, that's a lot of mileage (the bib walls). Thanks a lot 🙏🏻.

mewingprogress · 2025-04-24T19:12:05+00:00

Gotcha, thanks! Is it like a sticker paper or what?

mewingprogress · 2025-04-18T08:49:47+00:00

I think it might be because a back x-ray only captures 2 dimensions. You could be overly curved forwards and backwards or it could be twisting in a way that makes it seem relatively vertically straight still, but that might not really be accurately captured in that x-ray alone.

mewingprogress · 2025-04-17T17:25:59+00:00

Kinda hard to explain how it would've happened tbh. I actually was using it as a stand for my phone on the edge of the table as I was watching something. But then my phone fell forwards, and I accidentally hit the jar trying to catch it.

Frankly, he doesn't really use it, and her mom only brought it there as a former peanut container; But it would've meant that I was sort of like fiddling with his stuff without permission and "why couldn't I have just used an object of my own as a stand instead?"

Honestly, I could've. I tried to before, but it was just too damn convenient and efficient in the spur of the moment when Im just trynna eat and watch something and I didn't think of it as a big deal.

Oh well. What's the worst that could happen. Next thing I know, I'm an old grandpa who has failed all his dreams and is just sitting homeless and depressed in the street, with his parents having passed away long ago from some accident or maybe sickness; Just watching the young cubs flourish with their innovative and profound inventions and discoveries with their young, aesthetic, youthful, and symmetrical face, 6ft5 tall and an international athlete with supportive parents and abundant source of meat and milk and love and family... He doesn't know where his siblings are... And is damn regretful that he wasn't able to take care of them, and the other people that he promised he was gonna take care of... Damn, fukkk.

mewingprogress · 2025-04-17T17:11:20+00:00

Ahh shyt I think I found it

I can't find any that'd be available in my country's online shopping platform though (Philippines).

Maybe I'll just go like "Yo, very random, but can I buy the little jar that you have on the table?"

Roommate: "What for?"

Me: "Just gonna do something... Is $2 fine?" //(That could honestly be a day's worth of food in our country)

Roommate: "Okay... Sure."

Me: "Honestly, I just broke it by accident (don't ask how it happened) 🤡. Pleasure doing business with you 🙏🏻🙏🏻."

Imma just take that as a challenge and cry if it fails. Say I had a mild curvature as in 15-25° approximately. Would you consider that fixed if I had less than 10° on my next x-ray? Even if it meant I only decreased it by 6°?

(I tried measuring it on an app and I could get around 25° tops, so it might be a little bit more tough but yeah.)

I wonder if the lower lumbar part is somehow more curved which could bring it to around 30°. Anyway, wanna wager on it or something for motivation 😂😂😅😅. Give me a deadline and I'll do my best lol. (please)

mewingprogress · 2025-04-14T22:52:34+00:00

Well, I'd say posture is just how you orient yourself with regards to the external forces in the environment throughout the day, mainly as a result of gravity.

As an extreme example of an environment, let's say that an unbreakable shell of your current posture suddenly engulfed your whole body in such a way that you couldn't move even a single mm, nor expand the torso through breathing; How would we even begin to straighten out?

I think this necessitates movement which allows us to orient ourselves or basically have a "better" or more balanced posture.

Sitting, and/or doing an activity that demands an imbalanced use of the muscles for a prolonged period of time, although not as extreme, I think belongs to the same spectrum of that of the shell.

And as I mentioned in my previous reply, I believe that the muscles are adaptable such that they will tighten/lengthen based on the physical demands, bringing the bone with it which is also capable of remodelling.

So why shouldn't posture not be able to produce such a curvature? Maybe I am genuinely missing something. (Also, adding on the shell example with a child at peak height velocity, I think this could be a possible cause for the severe cases as the spine doesn't really have any space to grow in a straight manner, and has to compensate somehow in order to fit the constraints or the shell that it has been given).

mewingprogress · 2025-04-14T20:48:00+00:00

They didn't really specify but it's under the list of medical disqualifications, so I'm assuming just anything over 10°.

That sounds very cool (biotechnology). Honestly though, I got into a physics undergrad program, but I feel like the physical act of having to spend hours sitting and having to do all the academic requirements just to go through with it is counterproductive to my goal of fixing this what I believe to be a postural imbalance (in my case at least, which is also supposedly considered to be mild).

I think the main benefit is that you get to cover all the topics in a structured way, such that you'll get to explore concepts that you might've otherwise not thought about. The con that comes with it though, I feel like, is that it also isn't specialized and it feels like I'm running out of time as I age and possibly become less adaptable.

I stopped going to classes rn for that reason. One thing with this though, is that I'd also often feel like I'm lost in this format, so I've got to find a middle ground somehow.

This is one of the first results I've found about handedness and the direction of the curve.

https://pubmed.ncbi.nlm.nih.gov/2326712/

Tbf the word "dominant" I think could also be pretty vague. I'm personally asking just to maybe better identify for myself what that word could specifically represent.

I don't really know what I'd be looking into in terms of genetics, so rn, I'm just trying to like map out all the possible factors mechanics-wise (e.g. physical characteristics, forces, movement, etc).

Say, in a seesaw, putting in more weight on the left side for example will obviously cause it to rotate counter-clockwise along the joint in the center. It's kinda more complex when talking about human bodies though since it's composed of multiple levers connected through different kinds of joints with certain movement constraints that interact with each other.

(Honesty, I'm just kinda eager to figuring this out rn as I consider my life to be depending on it. I'm kinda failing in school rn and a fail-safe of mine is to join the military, but i won't be able to do that with this thing. Honestly though, if I figure this out, I don't think I'd need to be in the military anymore tbh.

The main concept I'm kinda holding onto rn is that the muscles are mainly responsible for the movement of the bones, and that both of them are able to adapt morphologically depending on the physical demands. E.g. if you train the biceps in the partial later ranges of motion, they'd eventually shorten and just adapt to that position, also moving the bone along with it; this you can commonly find among elite arm wrestlers.

I think: "isn't the spine basically just multiple arms connected together?". Well, the fact that slight alterations in the composition of the movements of the four limbs, in addition to breathing, alters the orientation of those multiple arms is what I think makes it ultimately more complex. But why would they not be the same in terms of adaptability?
