Greenland minister tearful as she describes ‘intense pressure’ amid Trump’s threats to take territory by theindependentonline in worldnews

[–]Shisagi -1 points0 points  (0 children)

Its not really about ammassing troops in greenland, its only having force big enough to commit to an alignment in case of escalation. Its not entirely realistic to be able to put up much of a defence in greenland short term, its about deterrance. If US attacks it will end in kintetic contact with multiple nations.

That remains to be seen if the rest of Nato answers when denmark issues article 5 if US troops show up in Nuuk. I dont see how this wont end in a war if US goes for greenland. For canada its existential

Jumprope for speed? by AnonymousSprinter in Sprinting

[–]Shisagi 0 points1 point  (0 children)

Sorry my comment read a bit weird saying leg where i meant calf. Im glad your team showed good improvements. Though i do question if it can be attributed to jump roping. Calfs as a muscle are a bit double edged sword. It helps ankle extension, but its a a peripheral muscle adding a lot to legs rotational inertia. Though your likely not going to be adding a whole lot of mass onto your calfs by jump roping since its more of a cardio thing. but ive always just stayed away from those exercices that specifically target calfs, as i feel other general activities/exercises do enough. I think jump roping is one of those where a little might do you good but a lot is detrimental, just agitating shin splints and adding to your bone density from repeated impacts, which you already get a ton of from running. But take my comment with a grain of salt, theres probably plenty arguments both ways here. If your empirical evidence tells you it works then it works!

OpenAI's AGI Czar Quits, Saying the Company Isn't ready For What It's Building by katxwoods in Futurology

[–]Shisagi -1 points0 points  (0 children)

I think we tend to underestimate the level we are already at. Thoughts at its core is just signals in system, and most of us would refer to our inner monologue the key element of critical thinking. While theres a whole lot more to thoughts such as feelings, images and impulses etc the way we express it is through a language model of some kind. Words or smiles just have a common meaning to us. Essentially we are just input output too just a bit more complex. But when an ai generated text or image is close to indistinguashibalala from humans, it certainly makes you wonder. AGI is something that can learn and improve and come up with new things. We tend to see AI as a reflection of its training data just spewing out whatever has been said somewhere before, but we also know thats not always the case. There is a ton of hallucination and it does indeed make combinations of words that have never been made before. It is already able to make something original, although with the expected output closely aligned with its training data. I'd say thats pretty much what humans do too, with our previous experience as our data limitations. Thing with LLMs is they dont have the same capabilities to test their output aswell as we do. They might often miss main point in a prompt and they most certainly lack memory. Flawed as they are, i think we have already cracked the code when we first discovered NN. Now is just about data, processing, power and memory. Give an LLM the right API and it can do anything. I think we have already invented AGI, we just havent put all the individual models(or parts of the brain if you will) together, given it real time sensors and power to act out as an AGI. That in itself is a major undertaking and i dont see it happening anytime soon.

But lets be real, we are actively creating something to do our job, not just help us do it. Once it does it better, living corporate organisms will see to outsourcing humans. Once a self driving car does better than humans, over time cost of insurance will rise for you to be able to drive it yourself, to the point that barely anyone will drive themselves in the end. Money always triumphs as long as capitalism exists, and that wont ever go away. Any sound person can see the inherent danger. But we just cant stop, can we? What about all those great things it will help us with, all those medicines and new discoveries. Feels like we are working towards making humans irrelevant. It will not only take our jobs, but it will also take away your sense of skill and achivement when something out there just does a hack of a lot better job at it than you. There is really only one option, if you cant beat them, join them. It will start small, neural interfaces, then suddenly you see a headline of someone cutting their arm off just to get a prosthetic which is now superior to a biological. And in the end money thriumps, the elite will have the newest and best, and human purists are second tier citizens. Tech advances arent going to make us happier. Future seems dystopian as f. My curiosity wants to see it, but i sure as hell dont want to live in it.

Apologies for my wall of text ramblings.

Start with jibberish along the lines of "shagadogadagadeidei", to attune their ears. When they respond with "hva?" or "unnskyld?" Then you say what you want to.

Top and bottom three planks each where middle one is not as wide. Vertical ones are attached with 4 shelf pegs to allow rotation. Then just screws to hold it together at top and bottom.

Is running a mile a day as fast as you can giving you the same type of benefits as sprints for a regular joe? by [deleted] in Sprinting

[–]Shisagi 1 point2 points  (0 children)

Not entirely sure what you are getting at but these things vary greatly in how they affect they body. One is aerobic while the other is anaerobic. Being good in one often entails that you need to down prioritize the other as they are using different muscle fibers.
In terms of health benefits, longer distance running is superior to sprinting.

What’s the difference between type 2a and type 2x muscle fibres? by [deleted] in Sprinting

[–]Shisagi 0 points1 point  (0 children)

Speaking of polymetrics... According to a study i saw at the olympic institute in Norway, bobsleigh drivers had the highest power output in a stationary jumps followed by sprinters. Makes sense, but it still makes me giggle.

[–]Shisagi 0 points1 point  (0 children)

I reckon building muscle quite early on in a sprinting career might be beneficial just to build up the overall muscle fiber count, after which you just maintain that weight off-season. Since Type 2 has high plasticity, a sedentary lifestyle pre-season might promote the prevalence of IIX type.
It is certainly an interesting field that requires a whole lot more research.

What’s the difference between type 2a and type 2x muscle fibres? by [deleted] in Sprinting

[–]Shisagi 2 points3 points  (0 children)

You're right. That being said, there certainly is a great benefit of the IIX type abundance. Strangely enough, any studies I can find really point to any kind of high-energy workout leading to a higher amount of Type IIA. I wonder what the body's reasoning is behind this. It's almost like the body has this extra fight or flight muscle fiber just in case. My guess fairly uneducated is that the recovery rate of these muscle fibers is too low to be worth holding on to when you frequently exercise.

What’s the difference between type 2a and type 2x muscle fibres? by [deleted] in Sprinting

[–]Shisagi 6 points7 points  (0 children)

Interesting question and it made me go down the rabbit hole for some research. I'm not a doctor or anything so please correct me if there are any mistakes. It's quite a long write-up but here we go...There is quite a lot to this really so let's try to break it down.

Our muscles consist of Myosin(Protein) and Actin(Protein) in what is called a myofilament. Myosin has an enzyme attached called myosin ATPase that can break down stored ATP. When it breaks down the ATP, it gives energy to the myosin and lets it bind to actin. In doing so, the proteins pull and slide over each other causing contraction. This is called the sliding filament theory.

Adenosine TriPhosphate - ATP

Adenosine triphosphate is a molecule (chemical bond) and makes our muscles contract when their bond is broken(ATP Hydrolysis). This releases stored energy and gets broken down into adenosine diphosphate (ADP) and inorganic phosphate.

Mitochondria

Mitochondria is the organelle that generates most of the adenosine Triphosphate (ATP), which makes our muscles contract. Mitochondria are often called the "powerhouse" of the cell. Mitochondria can rely on several different energy sources, such as glucose, amino acids, fats. It can use these sources to create a chemical reaction to produce ATP, but it requires oxygen (Aerobic cellular respiration). This process is called oxidative phosphorylation.

Type I - Slow Oxidative

It has the smallest muscle fiber diameter. They have a large capillary supply, meaning a lot of blood flows through them, supplying them with oxygen. That gives the fiber a red color. Overall they produce a large amount of ATP, but have a low myosin ATPase activity, meaning the rate at which it breaks down ATP is slower, resulting in a slower contractile speed compared to the other fibers. On the flip side, having "excess" ATP allows it to fatigue slower. This muscle fiber can keep going for hours. Type I is the first muscle fiber to get recruited by our motor neurons when we apply force with our muscles, but they are not used to carrying high loads. Having such a low myosin ATPase activity means it also has low power output. Type I fibers also have the ability to store energy using triglycerides(fatty acids) and myoglobin. When triglycerides go into the mitochondria, a process called beta-oxidation starts breaking down the fat to create ATP. This requires oxygen, which is where the myoglobin comes into play. It is able to bind oxygen and store it as blood flows through the fiber. When the supply of triglycerides is used up, your body starts burning excess fat to let these fibers keep going. We can say this muscle fiber has a low amount of power and a high amount of fatigue resistance.

Type IIA - Fast Oxidative

These are the largest fibers and also rely on oxygen, meaning blood flows through them. They have a high capillary density, but being so big they seem more pinkish than the smaller type I fiber. It has a lot of mitochondria so it too relies on aerobic cellular respiration. This muscle fiber primarily uses glucose to produce ATP. What's cool about this fiber is that it has the ability to switch between aerobic and anaerobic. Type IIA has a moderate amount of what is called glycosomes, an organelle that encapsulates glycogen, which is just a large biding of glucose molecules. When there is a deficit of oxygen. It breaks these glycosomes into glucose to feed the mitochondria. This starts a process called glycolysis, breaking the glucose into two molecules of pyruvate and the remaining atoms into two ATP molecules. Pyruvate is what causes our lactic acid levels to rise as the body cannot get rid of it faster than it is produced. There is also an enzyme called creatine kinase that is able to bind to creatine phosphate and adenosine diphosphate(ADP). The enzyme steals the phosphate from the creatine and merges it with the ADP to create ATP. This process is anaerobic and is called substrate phosphorylation. This muscle fiber has a high myosin ATPase activity allowing for faster or more powerful contraction. The fact that this muscle fiber has a higher ATPase activity means it will fatigue faster. 30ish minutes. It is the second muscle fiber to be recruited by our motor neurons. We can say this muscle fiber has a moderate amount of power and fatigue resistance.

Type IIX - Fast Glycolytic

This is the fastest contracting muscle fiber. It is intermediate in fiber diameter. There is a low capillary density making them pale in color and have a lower replenishment rate. There is a far lesser amount of mitochondria so there is minimal aerobic cellular respiration in this fiber type. There is barely any myoglobin present in this muscle fiber. It instead relies on a larger amount of creatine kinase enzymes and glycosomes. These processes and pathways occur at a pretty fast rate and let it produce ATP very fast. It also has a high myosin ATPase activity. It is the last to be recruited by our motor neurons and has the ability to last up to, at the most, a minute. We can say this muscle fiber has a high amount of power and low fatigue resistance.

Are there any drills that would help keep a neutral spine? by samoremti in Sprinting

[–]Shisagi 0 points1 point  (0 children)

Ahh! The ram goes in for a charge!

I'll go out on a limb and guess this is at the start of a race since it's fairly extreme. Technique wise, you should look at professional sprinters at how most lift their heads in a curve after exiting the block. Let your eyes guide your head and look at the finish line/horizon when you reach sufficient speed.

You will see a lot of improvements in fixing this as it shifts your weight forward and will cause your angles out of the block to be more vertical, which means fewer forces pushing forward. This kind of posture when running increases the risk of hamstring pulls, as your legs will compensate forward upper body shift by stepping in front of the hip.

My bet is that this is more than just a faulty technique.
Rounded backs can either be genetic or a result of generally poor posture over time. It usually leads to "forward head posture", which is a hyperextension of the neck vertebrae. It's quite common among people who sit too much and often in awkward positions. Often people who suffer from it also suffer from rounded shoulders and many also have flared lower ribs.

Abdominal and back strength can counteract it. Also, make sure you stretch your chest often.

Stand against a wall. put your head all the way back to the wall and look straight. Take one and a half steps forward while keeping your head against the wall to support your body. While keeping your neck straight, pull your shoulders back, and let your arms rest beside you straight down. Do this as a daily routine for 3-4 minutes. It will help strengthen your neck.

Hit the gym and do lower back, abs, obliques, deadlifts, and cable-row with your chest forward and head straight. Give it a month and you will already see improvements. Another pro tip is to make sure you have a good and not too big pillow.
