[HN Gopher] How fast can a human possibly run 100 meters? ___________________________________________________________________ How fast can a human possibly run 100 meters?

We | build giant coliseums costing hundreds of millions of dollars | devoted to keeping ice cold in the middle of summer just so | people can answer the question of who is best at stick puck. | bluefirebrand wrote: | Sports serve a social purpose, and contribute positively to | society's overall fitness since most people playing sports | aren't pro athletes | | A 100m sprint, as fast as humanly possible is super | impressive, but the person you're replying to does have a | point: this is an extremely specific and narrow activity with | no purpose other than competition. You don't socialize with | sprinting, and most people wouldn't use 100m sprinting as an | activity to improve their fitness | | At best, it's designed to test fitness, but it even fails at | that really | SketchySeaBeast wrote: | I don't think your second paragraph follows your first. | Just because you're doing an activity like sprinting solo | doesn't mean there aren't social elements. The Olympics | this summer will prove that hundreds of million if not | billions of people can come together around sprinting, and | several dozen other extremely specific and narrow | activities, if only for a brief time. | bluefirebrand wrote: | This doesn't reflect reality as far as I've ever seen | | Hundreds of millions if not billions of people may | _watch_ sprinting, or diving or any number of niche solo | sports, but do they really care further than "I hope our | guy wins"? | | Do they care about the technical aspects of running or | discus or whatever else? Not a chance | | It's not even remotely close to how passionate people get | about team sports. Millions of people will celebrate in | the streets if their soccer team wins a medal. People | will argue endlessly about the technical little details | of a soccer match, the calls refs make, etc | | Solo sports aren't really comparable to team sports in | the social aspect, either for society or for the players | on the teams | LargeWu wrote: | Nobody who lived during the Cold War would say that solo | Olympic sports weren't part of a team sport, the team | being your nation. A solo gold medal in one of the | premier events (100m dash, gymnastics all-around, figure | skating) was just as intense as any professional league | championship ever was. It's not an exaggeration to say it | was proxy warfare and possibly prevented actual global | war. It was a way for those nations to express dominance | off the field of battle. | Nashooo wrote: | Just because it is not a team sport does not make it not | social? | drdaeman wrote: | Can someone help me to understand this concept? In | particular, _why_ so _many_ people watch it - _what_ drives | them them do so? | | I'll try to explain my own vision, why I think I don't care - | which, of course, is entirely subjective thing, so despite it | may read as such it's not exactly meant to say "[some] pro | sports are nonsense" but rather more of "[some] pro sports | don't make sense for me". | | Say, Olympic games. I can watch the opening ceremony (it can | be visually or aesthetically impressive), but I don't care | about the actual event. Yea, some folks do some impressive | things, that... utterly fail to impress me. I'll try to | explain why, and I wonder how others are different in this | regard. | | I can understand watching sports that have a significant | strategy component to them. I would've probably watched Go or | chess if I would be able to understand what's going on there | (I don't), but I occasionally watch e-sports and those can | impress me with how people think outside of the box, doing | things that no one thought of - but that are so obvious in | the hindsight. For those kind of sports, when I understand | the game mechanics and when those feel interesting to me, I | can relate and feel engaged. | | I have a suspicion that a number of people watch it (among | other reasons) for the "this is _our_ athlete(s) doing it " | vibe. This is something that doesn't click with me. Never | really did when I was a kid (the country I was born in | doesn't exist - and good riddance), and since then I've | immigrated a few times, so - long story short - save for | obligatory subconscious biases, I don't care about other | folks' flags and passports. But even though this is not | commonplace (I guess), this doesn't feel like a reason why I | have no feelings for the Olympics. Back to the e-sports | example, I watch international events, and people from | different bubbles bringing their different strategies and | play styles makes watching fun, as the games are more | diverse. | | So, when someone's running, jumping, lifting, throwing, | shooting, spinning, or alike... I honestly don't get what | impresses so many _viewers_ so much everyone and their dog | seem to be glued to the screens. Please don 't get me wrong, | I _don 't_ want to diminish athletes' personal (or team) | achievements. What they're doing is objectively impressive, | but subjectively it's in some... detached, unrelated way. | Also, as someone raised on sci-fi I can't shake off the | feeling of it being sort of unimportant or meaningless on a | global scale - I suppose I'm gonna give post-/trans-human | Olympics a try, if I'll live to the day, maybe I'll find | something to cheer for. Not sure. | | Either way, in the modern day, personally, I don't feel any | engagement as I fail to relate with the athlete, leading to | the total lack of the entertainment value for me. Best I can | do is "uh, that looks fast/heavy/far/...", but 9s, 9.5s, or | 12s are all the same for me - just "fast" - nothing in my | brain fires off, as I don't have any experience of such | speeds/levels of exertion anyway. So I wonder, does it for | others, do they subconsciously tighten their muscles | watching, do they feel connected or something? Maybe not, | because people also watch races and I suppose they don't | associate with horses? | | As you can see, with all this blabbering and guessing | (sorry!) - I'm really confused here. I realize that even if | someone explains it to me, I still won't feel that way, but | what I'm missing is the idea - I only have guesses, and I | have no clue how accurate they are. And I'm curious to | understand others, even if a tiniest bit better. | | ====> tl;dr: If y'all watch the professional sports (esp. if | aren't an athlete yourself), what makes you engaged and | entertained watching it? | | Thanks! | k__ wrote: | Maybe, it's like art and math. | cglace wrote: | People want to see who is the best at X.

You have Einstein's "Dostoevsky gives me more than | any scientist, more than Gauss!", and I don't think | anyone of note ever said anything like that about any | athlete. Yes, pro sports beget more pro sports, but | that's not a positive feature. | SketchySeaBeast wrote: | It seems like you're over-intellectualizing the human | experience. You don't think anyone has been inspired by | sports? I just watched my entire city come alive with | Stanley Cup fever. People were having a great time, it | was a party the whole time. | | I barely understand the sport itself, I'm not a team | sports guy, but to deny the excitement, inspiration, and | sheer joy seems ridiculous under the crushing weight of | the energy sports can bring people. People use it to | better themselves, not just trying to get more pro | sports, and that's a goal I think every person should | strive towards. We are thinking things, but we're also | masses of tissue, and it's important to celebrate that | connection and that part of us. | aeyes wrote: | > You get no getting new [...] inspiration from watching | someone run. | | I'm an amateur runner and I get immense inspiration from | watching pro athletes run, I'll never get half as good | but it gives me a huge push to keep working towards my | own goals. | SketchySeaBeast wrote: | I feel like people railing against these things are | people who aren't aware of the various subcultures.

That said its like we've trained so acutely | for the test but the test doesn't really answer any good | questions. | | Historically running had a very important part of humanity. | You needed to run from animals for hunting, if you were a | warrior you needed to fight and run, etc. It feels like this | is one of those races that was historically important as a | human metric but no longer has the heft of value except for | nostalgia. | SketchySeaBeast wrote: | What are physical tests that are actually important to a | modern day human?

There's some skill and physical | conditioning there, but not a whole lot; at that speed, | there's a lot of instant feedback on form, which helps | encourage one to get low and tight. | | I think if we're talking about how fast you can get your | bike to go, flat land, still air is implied.
