This video really reminds me that listening to someone speaking about their passion is really interesting. Regardless of my interest in that passion originally.
Asking a good question takes just as much brilliance as answering it.
I have yet to be asked a brilliant question about my researched topic: _synchronistic mathematics._
I would agree with your premise. In reality, people ignore topics not promoted by leading corporate sponsors, or theories acceptable to established schools of thought.
I believe as we continue to push technology, it's going to continue to be more of a philosophical argument as to what the limits should be. When does the return of tech take away the physical prowess of competition. This all started with Bowerman dumping rubber into a waffle iron, and look where we are now. Crazy. Love this discussion.
the tracks in general have also changed.. lets not forget that.. unless people are running on the streets.. then you compare.. did the people in the past run on dirt/gravel roads then?..
@@Mellowyellow8888 really good point!
Let's have an old school Greek Olympic competition. No clothes, No shoes, Absolutely Naked.
This reminds me of the clap skates for speed skating, or the hydrophobic suits swimmers used to shatter records.. There is always an edge, or competitive edge that the best use to push past the previous status quo.. "The Blade Runner" also comes to mind .
True, but things like those speed suits were ultimately banned, and it levelled the playing field. Not sure why this shoe thing is being allowed to go unchecked if it represents such an unfair, uneven advantage. It will be very straightforward to ban carbon plates and similar, limit the foam height (which they've already done to 40mm), and even check the elasticity of the foam. Everything from F1 to triathlon puts restrictions on technology. Competitive running shouldn't be any different.
@@alexshaykevich509 they banned specific shoes for competition before. I think it was the Nike Vaporfly Next, was banned last year..
Hidden springs in the heels.
I had a dream once where I was wearing rollerblades with small jet rockets attached to the sides of them and I remote control them but they where too fast and when I reach an extremely high uncontrollable speed I woke up.
he he nice
Is this about platelet shoes?
If you do the math, the Nike shoe returns about 7 joules of energy. Coincidentally that is about the same as the Iliotibial band. So someone running with that shoe is effectively running with an extra pair of iliotibial bands or alternatively an Achille's tendon that is about 14% more efficient (the Achille's tendon returns about 50 joules of energy). You pick the comparison.
Super fascinating discussion.
If esports makes it into the Olympics then what about chess and bocce ball.
Chess Olympiads are a thing, never been under the IOC AFAIK but maybe that's a good thing
as long as it brings in enough money/sponsors, anything is possible
If anime taught me anything is that augmented people still have to watch out for Gearless Joe.
One Punch Man comes to mind.
I'm mostly curious about PEDs and that side of competition.
Mushrooms
EPO is the most useful and gives around a 3% advantage. Basically their hard work + training + genetics makes it impossible for 99.9% of the population to match them, even if people take whatever PED's they like, so it's kind of a topic not worth discussing.
Tell that to TJ Dillawshaw after he got KO’d by Cejudo in the first round
Imagine how fast runners be if nike made vaporfly ass plugs.
LMAO
"It's unfair to have to spend $250 on a pair of shoes if someone else can't even afford a shoe"
FFS who are we kidding?
Let's double it: How much does a $500 shoe represent on the journey to a championship?
1 minor injury will set you back $500 in medical and physiotherapy costs.
The ban was marketing ploy by shoe manufacturers not wanting to be shown up in an Olympic cycle.
Simple as that.
These shoes last a couple of weeks of training before you switch to the next pair. It adds up.
In the Olympics athletes from wealthier nations and with bigger sponsors will have a stronger advantage over those from humbler origins.
"So is there any extra innovation that's still possible?" "Uh ya, wheels, gas powered engines..."
The best shoes are NO shoes - 🤣🤣🤣
The arguments against the shoe sounds like ppl saying tennis rackets shouldnt be made with carbon fibers because it gives an unfair advantage against the wooden rackets.
no also because wr's and personal bests are so central to the sport
Carbon plate spring etc. Where does the line go? When is it no longer a "shoe"? Put rockets on them things, and call it a "shoe".
It's just a thin layer of another kind of foam. Far from rocket shoes. Go running in these new shoes tho like ultraboosts or zoomx sneakers and just the comfort factor will convert you
Lex, e-sports are what you said, a new sport. Like everything, the beginning is chaotic and wild, give it some time for regulations, competitions and governing bodies to get it right and im almost certain esports will overtake normal sports in terms of viewership, sponsorships and all that.
Does Nike's +/- 800 patents per annum present a barrier to innovation ?
Alternate theory of the reason for patent protection (my speciality in law school). Perhaps there would've been no benefit to innovate and spend as much in R&D that Nike has, without such protection for 20 years (from filing). Some see it as a barrier, but in cases where Nike seems to be developing outside of what others are capable of, I believe it's pushing innovation.
Patents are always a barrier, that's the point - but the reality is that, like always happens, the competition has already developed their own versions of this technology
What shoes are these exactly??
nike vaporfly, alphafly and 4%, they all have this zoom x foam which makes them incredibly advanced and has allowed world records to be broken.
@@robertojofre15 thanks
I have these Nike shoes, and it's different.
What’s the name?
@@truhawaii5957 Nike Vaporfly Max
Carbon plated shoes should be illegal. The advantage and the immediate speed gains you acquire is similar to PEDs. If you have ever run in a carbon plated shoe let alone the Alpha fly you would understand how significant of a difference there is between the elite shoe and a average running shoe.
Guys look into barefoot shoes and into the book "born to run". Modern shoe design is horrendous for the feet and the whole body. Back pain? Knee pain? Deformed feet? Weak arches? It's all because of these nonsense narrow toe, raised heel, extreme padding, arch "support" and stiff shoe crap. Yes even podiatrists that actually know their shit and research more than the basics taught in school agree. Look it up please. For your sake.
I've been running in my Xero barefoot shoes for the past 2 years. I very rarely experience any discomfort these days.
I developed hip/lower back pain while running in my arch support shoes. Switched to neutral/barefoot mix and it solved the problem. Tried going back to the old arch support and the problem returned immediately, literally 5 mins into the run. You should retrain to run in these though but it's well worth it and it's how we evolved to run naturally anyway.
I have been using the Bedrock's, Lem's Primal and Altra Lone Peaks. After my Doctors telling me I need corrective foot surgery and to try not to run or walk too much, my feet are "correcting" from wearing these shoes without surgery. My distance has increased radically while foot, knee and hip pain are all but gone. These are zero drop "foot shaped" shoes with minimal to no padding
make sure to run with correct form when switching to minimalist shoes. if you continue heel striking youll end up with even worse problems
I can support this. 7 years or more running barefoot or minimalist, no injuries yet.
Who’s doing a hundred miles in under an hour lol
Are these shoes still made by 6yr olds?? Because those 6yr olds know how to make damn good shoes
What about barefootrunning?
The origional and the best.
@@peanutgallery7753 My feet are feeling amazing, I use bsrefoot shoes. I had trouble in the beginning with my calves, now that I've learned the technique and developed the muscles, I feel amazing.
You wont get the best time you can get, apparently, but then, who cares
@@peanutgallery7753 yeah there’s homeless people in the park I run. Don’t want to step on a needle or glass if they leave them around.
Google Tarahumara
I think this shoe advantage is a lie. Here's why. Great runners don't bounce up and down. They touch and pull. It is inefficient to be bouncing. So if you are touching your foot down and pulling forward, where are you getting your bounce back. There is no bounceback.
Then you would have trouble explaining why we evolved an Achille's tendon which is NOT used during walking but is utilized during running. They recycle energy (about 50 joules) making us more efficient as we run. Those shoes do the same thing (but only about 7 joules).
From what i've experienced, vertical movement is relative to the forward horizontal movement while running.
What humans foot turns into the shape of a triangle at the toe? Why is all shoes shaped with narrow toe. Makes no sense
The 'point' in a pump or loafer for example is purely for fashion. Certainly not all shoes. Many shoes have very wide toe boxes.
@@mwbeck almost all have narrow toe boxes. Have you ever been to any shoe store before? Everything is narrow. Basketball shoes, tennis shoe, running, etc . I literally have deformed pinky toes from growing up in narrow shoes. I still have yet to find a shoes that doesn't. I've tried 17 pairs of shoes since 2020 and they all still have it
@@grassfedcontent never skated before then hey! Skimpy creps are known, makes a huge difference when jumping, or falling, down a 10 set.
Brooks makes good wide toed shoes.
@@grassfedcontent Get barefoot shoes bro what are you doing. Merrell, vivobarefoot, Xero and many other brands.
Get Nike off the thumbnail Lex
Modern shoes are ugly as hell but they seem to work
Barefoot 🦶 shoes are in
All companies have carbon fiber plated shoes, nike set the bar, others have caught up. What’s the big deal? Bikes get faster, every sport advances. You are wrong, it did come to market, its the alphafly.
So why don't we run barefoot? I mean, if everyone isn't using the same shoe then isn't that the same thing as taking a performance enhancing drug? Nike Sponsored = Drug Sponsored.
money talks
nobody has identical genetics, so any competition is inherently unfair.. which is a big reason I don't really care for any of it
@@frydac Sports at its essence is not really a celebration of individual ability but human ability. To that end, even our innovation is considered an extension of inherent human ability.
Is this podcast even about AI anymore?
All that flat/minimalist footwear stuff bullshit?
No. It still strengthen your feet. If you start early they will give you a natural technique. They are talking about running fast. Not what is good for your body.
This video sponsored by nike....
Sorry ultra boost is far superior
Running barefoot is better
All shoes are terrible for our feet. The Tarahumara Indians run 100 miles in one day. They run barefoot or with sandals. They run on the balls of their feet and NOT heel to toe which is terrible for your spine and does not disperse the shock properly. Society is a farce.
@@Iron-Bridge I switched to natural after developing hip/back problem in arch support shoes. It solved it. However, I don't think that there's no business opportunity in natural running (albeit not "barefoot") as there's still some room for innovation for the natural running shoe - most of us will inevitably need some kind of shoes to protect our feet while running from the environment (sharp objects etc.).
Lmfao no Indian runs 100 miles a day. Wherever you get your info, burn it. Ultra Marathon Runners can barely get 100 miles run in under 32 hours. It takes most about 48 hours to run 100 miles non stop. No one is regularly running 100 miles in a day my man lmfao. Are you high? Do you know fast your average mile would need to be? If you ran 4 minutes miles (world record shattering speed) for each mile, your looking at 6.5 hours. And guess what? No human is averaging a 4 minute mile over a 100 mile distance.
Those Indians aren’t the elite ultra marathon runners either. They wouldn’t win those races. It’s 2 different things. You’re comparing lifestyle vs competition
@@brettcarlson5450 You sneakily inserted the word "regularly" into you paraphrasing of the OP. He didn't claim they were running 100 miles a day regularly. 100 miles in 24 hours is about a 4 mph pace, that is pretty damn slow. Zach Bitter halved the time and doubled the pace for the world record. Its not unimaginable that many people, including the Tarahumaras, can run somewhere between both those extremes. Your odd extreme example of 4 minute miles over 100 miles does nothing to prove that people aren't capable of running 100 miles in a day. It also sounds like you aren't familiar with the Tarahumaras who actually do run events from 30 to 100 miles. They aren't the only ones. Ultramarathons aren't a modern invention their are many historic and prehistoric examples of ultramarathon level runs.
Massive loss of respect, no high schooler is looking to run in vaporflys. Get over yourself with the shoe tech. Boucher lost to Linden and Linden wasn’t in Vaporflys. What a joke.
