My fav sport is running. When i run, sometimes i start grinning like a maniac for no apparent reason.
What are you, fucking gay?
That's me in volleyball AND running haha
I'd run the other way
Same xD
Same dude, we're both maniacs
i'm made for sitting, I've been training for 20 years
23 now?
So how do avoid getting sore butt or prevent your tailbone getting sore without moving positions???
you rest after a long time train
@Abdullah Hossein 27 now?
Two years ago I would have never thought I would be able to run 5 kms. 1 km was my norm and 3 was the limit. I ran several 10 kms so far and am preparing for a half-marathon. Its cool how quickly the body adapts when you start pushing it.
James Dillinger cool'
It's what you're made to do.
@@seanthe100 Yup, I completely agree. The biomechanics of our body is literally made for efficient long distance running.
I became obsessed with running and Human evolutionary biology years ago, never stopped running since. I've run 2 50k ultras now, both in Utah and my best time for a 50k is 3:44 but difficulty varies a lot in ultras.
@@Apistevist That's quite an achievement. Well done!
The longest run I ever did was 10 miles. Eat that, Cheetah! You're tired after 100 meters? pathetic.
the longest i ever ran was 12mile in freezing weather, in the rain, that turned to hail on top of a fucking mountains.
Try running full pelt at 75mph
TXV1300R
sorry what to keep my legs...
I can do more because I am in cross country
Try running Cross country in the Rockies mountains where we sometimes run up to tree line.
i can outrun a cheetah... hold my beer .
Ahahaha you go man!
thexophguy In an endurance race yes, but not in a sprint.
No cheetah can run faster in a zigzag course than a drunken human.
i never get drunk.. ever . never ever.
Aaron Fl k
Ce
Yeah! Built to run!
I can run a whole 50 feet before collapsing from exhaustion, woo!
Malik Pennie Yeah. XD
I am not fat, but I am certainly not in shape (not saying you called me fat btw).
Malik Pennie I know you were not calling me fat, that's why I made that extra little note in parenthesis. Don't want to start a fight over something stupid like that.
XP Yeah, nobody really starts out a skilled runner. They need to do it all the time, be it for sport or for survival.
+Phantomhive That might be true. But in under a week ( if you ran every day and pushed yourself ) you can reach 2x the distance you originally started out. It might be off putting at 1st but like most things, the more you do it, the better you become :)
Opticalx Yeah...
too bad I don't enjoy running even when you don't consider stamina and such. XD
I do plan on getting into shape soon, though. I wanna start getting stronger and more flexible so that I could maybe do a bit of light freerunning/parkour from time to time. So when I start doing that, I will defiantly be able to gradually start running faster and longer.
+Phantomhive funny i like to sit a lot, and when i walked for 24 days for 5 hours, (about 4.5 miles) everyday i had bone degeneration, not tendom breaks or tears, but bone degeneration in me feet, and im like "yeah right humans built for running? we can't even walk right for god's sake and the body destroys itself"
So essentially Kim Kardashian should be able to run like Forest Gump.
That's what I got out of it.
i think also niki manah
Except that her ass is 99.99% silicone and not muscles.
She could if she focused herself in that direction , Kayne West could be support crew😀
In theory but her jupitar ass has it's own gravitational pull too strong that the force pushing her down is too high making her more heavier and not as fast as Mr.Gump
Of course it would take her a lot of training , to reach the level of Gump😀
I get a high from marathoning Netflix. Does that count?
Wow I almost skipped ur comment until I saw ur name lol. hey at what age can u start running? do u know?
+AwesomeGuy lol ikr! everybody sounds like an A hole on youtube. its not what people say, its who says it...lol
+Julia Wilde I get high WHILE marathoning Netflix. Try it sometime bro.
+Julia Wilde yes it does your getting in shape from moving your eyes around so much and using your thumbs to hit buttons on the remote
+Julia Wilde Yes.
i never get a runner's high -.- i get a high from strength exercises though and love doing it, but cardio is just a chore for me
+Dhalgrim Same.
+Dhalgrim Try to run 100 km and you will feel it. ^^
+Dhalgrim It's easier if you quit smoking.
+Dhalgrim That's called laziness. Its good to mix both cardio and strength training. You dont want to be one of those muscular guys that cant even make love to their women for longer then 10 minutes without gassing.
+031ish Or just look like you missed leg day, everyday xD
but were we made to run.... in running shoes?
Well she mentioned that our hamstrings and achiles heels get stronger after a long distance run, so maybe if we ran without shoes regularly, we'd no longer need the support that shoes give us?
concrete is a game changer
Justin Campbell I actually run faster in bare foot but I need shoes because if i dont i might damage my foot with pebbles
no the shoes were made to make us run better, not the opposite.
lol for some reason I run fast in bare foot I don't know why
I have to admit I'm the weird runner you love to hate. At 56 years old I ran a trail marathon, then a 50K up a mountain, and three weeks later ran a marathon. At every ultra, I meet people who routinely run 100 miles. The human body is amazing. The worst thing you can do for your body is sitting all day. The human body loves physical challenges and will adapt. It can be running, crossfit, mtn biking, etc. I'm planning my next challenge now.
no you didn't
when I'm extremely stressed out, I go running. Afterwards, I'm happy for about a week
Jay H ok imma try
I'm a swimmer, would love a video like this on humans and swimming :)!
+Troy Reppas They have one! Just search something like "Is Running OR Swimming Better" I think that was the title. I can't fully remember :)
Swimming!!! Thank you Savannah
Haha I like both :)
+Troy Reppas
there's actually a theory that humans evolved the way they did from being swimmers called 'the aquatic ape hypothesis'. I think they did a video on it awhile back? not sure though.
+RasecVonWizzlbang nope they havent done a video about it, but that hypothesis looks very realistic, I have researched that same thing for a book/game Im making
i remember in middle school they had some program for pe that if you ran for 40 minutes straight without stopping they give you a certificate of recognition for it i passed it
how long do you run now?
Me 104th idk but i know i can run a mile in about 7 to 8 minutes without stopping it does take a toll on me though ..
That's a bit on the easy side, don't you think?
I'll probably jog like 95% of it, the other 5% is when people pass me and I think "You jerks. Stop passing me." and sprint like my life depends on it.
well that's something I guess
Oddly enough the worst thing to run or walk on are sidewalks, asphalt is just slightly better. Best to stick to more natural surfaces( i.e. Horse trails, grass and tracks) I wouldn't recommend beach running, as most are uneven, which can lead to lateral and medial strains in the ankles and feet. As with any type of physical activity moderation is the key.
+Paul Lucas I agree with everything you just said. After running on a really bumpy trail and the concrete footpath, I got a really big pain in my shins, and I haven't been able to comfortably run for the past 2 months.
Run safely, people!
+Savannah Egerton Sounds like you have the dreaded runners curse, shin splints. This has several causes, micro fractures along the tibia, strains near the talus and fascia inflammation(this is the most common). I recommend the R.I.C.E. treatment with some foam rolling for the distal leg on all sides, as well as using a ball for the bottom of the foot (lacrosse balls are the best). Switch to some cross training like swimming. When you do get back to running, I would suggest to cut your mileage by a 1/3 and use an ankle support and of course a good pair of fitted shoes.
***** Yeah, I had assumed I had shin splints :( Thanks for that information! I also had something wrong with my plantar fascia on the same leg, so maybe that leg will forever be ruined D:
I have been bicycling to try and keep fit while recovering, but I don't feel as good after biking as I do after running. Of well, maybe with those treatments you mentioned I can get better faster! Have you ever had shin splints before?
+Savannah Egerton Yes, I've had both shin splints and plantar fasciitis, mine was due to fallen arches but there are other causes that lead to inflammation of the the plantar fascia such as incline running, imbalance in muscular development in the calf and bone spurs. It's not forever ruined but will take some time to heal with treatment, anywhere from 6 -12 weeks. I would recommend the treatment I said before with additional treatments of stretching the big toe up repetitively throughout the day and using frozen water bottles(the smaller ones) to roll the bottom of the foot, just make sure you wear socks to buffer it, as you don't want to burn the bottom of your feet. Depending on the severity of the inflammation a compression boot may also be needed as well as surgery (in extreme cases or if there is bone spurs involved). Good luck, hope this helps.
***** Wow you seem to know your stuff! :) Are you a physiotherapist or something? You seem very well educated on this stuff :D
Yeah, my plantar fascia seems all better now. It used to click, kinda, and feel like a rubber band breaking in the arch of my foot. Idk if that was inflammation, but oh well :D I just left it for three months without turning suddenly on that foot so it went away :)
seriously? we can outrun even animal like horse? I thought horses are cross country runners
+HapZungLam yes, if the temparature is quite warm, our bipedal method is more efficient than their 4 legs
+HapZungLam Yes, on a per distance (mileage, NOT SPEED), a well trained human has the ability to outrun the majority of animals in a single running session before needing to rest due to our exceptional ability to vent heat very effectively through pores unlike many furry animals that overheat with much more ease.
Of course there are migratory animals such as wolves, who essentially run for a living so perhaps they can outrun us. Have a read on Google-Scholar, you might find a case study about it as I am by no means a specialist on the topic.
+Alexander Eriksen ^^ YUUUUP
+HapZungLam The man v horse race demonstrates this
Even cheetahs
I enjoy cuddling and sleeping with my ferrets :)
Now if only my spine wasn't messed up.
... well I didn't have to look far to find the depressing shit
VegaByte Thanks :)
Christopher Johnson here's hoping for advancement in medical tech, can't wait to see you on your feet
VegaByte I can walk just not run.
Christopher Johnson I see
We're meant for running? I'm so de-evolved then.
You have potential brother
Siddhartha040107 if you grew up in Africa you would have leathery ass feet and could probably outrun 90% of America bare foot
Well since there are 7 billions of us today, I bet that not all of us were evolved the same way. There was a research conducted on a tribe (I don't remember where that tribe is but I'm pretty sure it was some place that has a huge body of water) and they found out that they were able to hold their breath significantly longer than the average person because they were evolved to go fishing by using their hands and a small knife and since most Americans has stop running a lot for quite some time now, they have probably evolved to not last longer than the average person.
I love running
same
same
same
Me too
Nope
We are made for moving not staying at a desk being a brainless drone and watching stupid youtube videos or facebook ...
Pentru Barbati coming from your fatass
Pentru Barbati and here you are.
That's true, although some people were made to move AND use their brain.
Stupid people watching Stupid videos
Wow... that clickbait title, though
LOL, they changed it... wonder if I had anything to do with it
+Xinon Gladio It was, they changed it.
+2987ms
Yeah, I saw that, too! What was that about? It was originally titled 'Does Running Do More Harm Than Good?'.
+2987ms what was it
mj ramos 'Does Running Do More Harm Than Good?
***** It's a question that makes you want to have the answer, therefor, it's clickbait.
I really enjoy running, especially long runs- you start off slower, but then you sprint- so amazing!
Being a star track and XC athlete, I really enjoy this and I in turn learned something! Good video!
Lol I just literally just got done at a highschool cross country race like 30 minutes ago crazy
I love cross country what are you varsity boys or girls? I'm varsity boys and I suck
I'm varsity guys. yesterday I just got a PR and got 16:56. I'm a sophmore. I think it's the best sport ever
What's your pr HC?
19:30 as a sophomore just got into it and I love it
I saw this video as a recommendation after coming back from a run. I think youtube is spying on me. It's not like I even brought my phone with me and had the GPS turned on or anything. IF YOU ARE OUT THERE COME AND GET ME COWARDS.
Anybody who runs track knows that long distance takes training. You can’t just decide to run thousands of miles without insane amounts of training. Even then, some people are better suited to short distance sprinting. Which is why we have different event in track and field, like long distance, sprints, relays, and different field events. It’s similar to muscle cells. Everyone is born with the exact amount of muscle segments (couldn’t remember what they’re called) that they will ever have, but generally most people, including me, probably couldn’t run 3 straight miles without collapsing.
Very thoughtful analysis. Thanks.
Brilliant video, smart and highly educational👏
Wow we might not be the fastest but we can beat any animal at distance.. So cool!
How the actual fuck are we built to run long distances? I can't even run a mile without breathing like a jet turbine...
because you probably dont do a lot of exercising. Back then all humans could do was move around to survive and not get distracted by tech
Or macdonald's...
I run 3 miles every morning you run 1 mile once a year fitness gram I am just more fit than you
trust me if a cheetah chased you , you would run for your life faster than usain bolt
We stopped hunting then became pussies.
I love running, track and cross country for life!
really great video, learned alot
but how does it effect the other organs like the heart for example.
+foday S The heart is strengthened, and loses fat as there is a wall with a load of fat in it, and if you don't run, (or do any cardio) the fat grows and affects the way your heart pumps blood. (This is all only what I remember from year 9 health class)
So apart from the joint and cartilage degeneration, it is overall really healthy for you, just SACRIFICE THOSE KNEES!
Savannah Egerton so the knees don't regenerate?
Also i have noticed I can now sense my heart beating more while laying on the floor on my left side. Sometimes I can feel it beat while I am laying on my back...is that normal?
As said in this video, knees do regenerate (like the doctor. Ha.) but the impact of running still isn't good on your leg joints after a while :)
I actually don't know about that one, (after all I am only 17 :D) but I'm assuming it has to do with how your heart is positioned (although it is at the centre of your body, the left side is slightly larger than the right) so since there is more of it to the left, maybe the pressure of your right lung on your heart from gravity makes you be able to feel its' beating? Don't instantly believe this, though :) It is just my theory :D
Savannah Egerton know of any books to read about the heart since you took a class or classes?
+foday S Short story..... I was a thin marathon runner.
I ate garbage teenager food, had stressful thoughts; but stayed thin.
Heart disease runs in my family..............ergo; I got heart disease & got a stent.
I Changed my stressful thoughts and eating. I'm a-okay today.
Best video I've seen lately. This is great news for me, as I love to run. I had slacked off for a while and put on a little weight but started again recently. I think I'll make a video talking about how I used to be fat and totally changed my body through diet and running (among other activities).
Love your videos. Nice way to get abit of info with out getting head trauma hehe
So what specific speed and distance? I can sprint 400m and collapse, but run 3 miles and shrug it off(admittedly, I was running quite slowly)
Cool video clip. But why not get a runner to present it 🏃
So many butt jokes missed :(
I freaking love runners high. I used to smoke pot too, so it's extra rewarding for me. I like the idea that we are hard-wired to enjoy running, because it's much more motivating to get up and move. Although genetics may also play a part (such as if your parents were runners or not). Well anyways, I first noticed my runners high when I started to do 20 minute 5km runs, and I'd reach this point in my training where my heart is working its hardest and my muscles were burning where I'd feel extremely happy almost like my neurons were firing in just a way that made me feel "high", as if on cannabis or I had ingested THC... like it was my brains way of telling me, "good job" and to keep going. Really love the aspect of pushing yourself to new heights of physical fitness. It really brings on a whole new level of confidence, too. I was never really all that into running as a teenager, but as soon as I hit my 20's it became a favourite activity especially in the evenings when the weather is nice and cool. ^_^ peace out~
I don't run often, mostly because I'm too shy to run around my neighborhood but when I do run it feels amazing!
I work 56 hours a week. I do not have time or motivation to go for long-ass fucking runs. Endocannabinoids, you say? So I can smoke weed and have the same positive benefits? Good enough for me.
Can we smoke some endocannabinoids ?
You just motivated my run today. Thank you....
Very nice video with full of information... thanks and A big salute from India.
What about flat footers? 1st
+triigga s Got flat feet myself and it does start to hurt 5 kms into the run. I need to do more research into this and maybe find a custom pair of sports shoes.
+triigga s i have flat feet and i never have any problem and the longest ive ran non stop is 9 miles
Yes what about the flat feet? Why does it hurt when I run?
Flat footer 🙋 Yeah, it really hurts 😐
Suzie boo It hurts because we, flat footers, tend to over pronate when running. This results in more stress on the feet, knees and hips, and can cause serious issues if left unchecked. If feel pain when running and have flat feet (fallen arches), then buy a pair of stability control shoes (most brands have them). If the pain is severe, then go for motion control shoes. If you have pain even when walking, then see a doctor and get custom made soles for shoes, then will provide extra support.
I don't run a lot because I always have too poop, and I don't trust it anymore then...
+Buddy Jesus Oh I know, right! I also get a really sore stomach, and I know it isn't the stitch because it feels like period pain. So BOOM! Excuses.
But no really running is so freaking amazing especially in the rain
Sometimes its because consuming junk foods is the problem, but once you change your diet to healthier options your bowel movement when running will become less irritating. Happened to me before! Keep running :)
Sandeezy Ha, I wish that would work for me! I eat next to no junk foods, so I have no clue what's causing my pains :( I think I'll just stick to swimming/bicycling :D
+Buddy Jesus Try to eat light foods before you run (banana, grapes, raisins, white bread with jam, etc), avoid anything with fibers.
+Bas Q. Some people have to eat fiber before they run, otherwise they shit their pants.
great video
"Who am I kidding, the Ferret is totally my patronus" THAT MADE MY DAY!!!!!!!
What about walking?
Walking is good too , but you may have to walk a little faster to hit the fat burning zone😀
I'd say fast walking is superior if you only want to lose fat, without putting on too much foot muscle. Expert source: My sisters.
Hahahaha it takes a lot more than just running to put on a lot of "foot muscle"
I love that adrenaline rush you get from running.
Im 14, i often run 5 km perhaps 2-4 times a week. My question is that since i run before im fully developed as a human am i helping my future running self or hurting it?
This was a very interesting video, you mentioned that we were built for running based on historic hunting for survival although you never answered whether it harms you or not in the long term, which I found odd as I assumed that was the question you were attempting to answer based on the title of the video. Then you talked about joints degrading and tendons growing during a marathon run but never stated a lasting impact on the body post-marathon.
Anyway, I'll just make the assumption that running in medium amounts is healthy and supposedly prolongs life and ligament strength.
I love long distance running! I always get such a high from it!
I ran once. It was awful.
Interesting about the 'butt'. When I started into long distance running (in my 30s) and pushed myself from 10km to 20km for the first time, I was shocked that it wasn't my calves or quads, the muscles in my butt hurt !!! I had no idea the role it played, but I can contest that it does play a big one... um no pun intended there
Here's a two part question. Why does the average person sometimes wake up with headaches? What does it typically correlate with, sleep disturbances/deprivation, medications, or both?
Slow and steady wins the evolutionary process :/ haha...
Swimming is better :)
+craig nathan Maybe for you, but do humans outswim wales? I don't think so.
+MrBaronmoll that's exactly the reason why swimming is better duh!
+MrBaronmoll Wales don't swim - it's a country, however whales do swim.
Ryan Hewson
Sorry, second language speeker at it's finest.
craig nathan
I don't quite get it. We're simply the best out of all the animals at marathons but yet you think a form of movement that isn't necessarily natural for humans is better?
I always loved running. Did get that runners high. And what I called a second breath! Felt like I could run forever!
I do track and I wonder which is harder, sprints or long distance? I am a long distance runner
I still prefer bicycling.
You can mix it up with the bike 😀🏃
Mix it up for your hips sake
Mix it up with the Murph WOD or burpies.
This girl here is the prototypical geeky chick that has just the right dash of gorgeousness-the type you introduce to your parents and best friends ♥♥♥
Once she starting talking about butts I couldn’t help myself from wanting to see hers ......😂 true story
badtama07 ew. U nerds ruining this video
4 years late but I gotta call out the simpin
Do we get this high from other forms of endurance sports, such as cycling and swimming?
Ran track for 2 years in high school and never got a runners high but I did get a massive rush/high from competitive boxing
So homo sapiens chased their prey until the prey collapsed from exhaustion and that's the only way we could have hunted? Am I the only one finding this theory highly far fetched? A more logical theory would have been that since ancient humans were nomads, we had to move quickly from one shelter to another during the day. The worst runners got left behind and didn't make the night. Thus, only the best long distance runners reproduced.
Or maybe the bad runners starved to death?
Sorry but no just no
Dustin Smith Care to elaborate?
Probably this and the other theory
Hunter gatherers still do this.
Hey Dnews, you should follow up this video with how to run properly. With the modern shoes we've gone from running how we were built to utilising the soft heel that come with shoes. This heel striking causes more damage to the bones and joints.
Parkour is a great example of how this would mess up them if they heel stroked. They tend to fall from greater heights with higher impact. They train to beanie to continue to be able to do it well into their 60s. The secret is learning how people use to walk and run before the modern shoes. Taking off your shoes you will find heel striking to be painful. That's because the force goes through your bones. Shifting to the forefoot or balls of your feet will instead mean that the energy will be distribute to the muscles. You will also feel more springy and you create less noise while running.
hello dnews. could you do a video on cycling? (if you have done one already I'm sorry for asking)
Why did I always suck at long distance running then? Since kid I was always the guy who were very explosive could sprint very fast, I just never been good at running how much I tried I sucked at it.
Couldn't run more than one lap around my daughter's school track and now I've completed a 10k! Progress is wild! So is looking back at what little I could do before.😊
I read a article in the NY Post, about a group in Manhattan who ran every day, they have a club. I thought, what could be the difference as I was running 4 or 5 times a week, now I have just over a 8 year running streak, with 3 weeks & 3 days off last January when I broke my ankle, ice under snow, but the difference is amazing, & most importantly, anyone can do it.
running is the best and most complete exercise ., and it work from the very first time
looking good JW!
I really do enjoy running. I love it.
Interesting stuff! The ferret is our patronus as well...
I'm 18 years old and I smoked and now I have chest pain and I felt weak and dizzy what do?
Enjoi tomorrow y had to do that. The tape running on 22,5 last week
thats.. fucking terrifying. Imagine being run down over miles and miles, what a way to go.
In my younger days as a soldier I could literally run all day but I never enjoyed it as much as riding a mountain bike cross country. That gave me a high like a drug. I rode so much that walking started to feel strange and while riding I forgot I was on a machine.
is the same this try for cycling?
I had to pause this video a few time because I kept getting side tracked. This girl is way to attractive and I kept staring at her. I found my self having to back up the video and re-watch because the information is just as good. Thank you for sharing.
My friend says that ice baths are dangerous. Is this true because I really want to try it
I enjoy running but I am a bit scared to do so on a treadmill since someone made me fall off one.
a runners high is easy to get when you start running start to day dream and let it go on let your body do the work. once you stop day dreaming and thinking about running the high is gone. i have had it happen a few times by day dreaming while running cross county in high school.
I love running every once in a while, it's a well needed release
I've read studies that say short but intense workout is better than long workout. Both help with cardiovascular health, but short intense workout raises your IgA (part of the immune system), while long term exercises lower it...
Started walking bc I had 2. Had a serious operation & lost my vehicle home ECT. Got a house again. Still walking everywhere. My job accused me of taking Adderall I had so much energy. Now I really don't have to walk but I chase that hi. I only get it if I walk 180 min plus. The high makes u appear to be on drugs... except your on point. Total focus.
I am train driver and i like getting in a 3mile job prior to work. I find it really helps my mood and focus.
I like to run, but not like some people I see that will go out and run in rain, snow, 90 degree weather. I don't know why I like, I guess it's just kind of cool to hear the air go by which when you walk you don't get.
Walking I think I've done a couple miles at once. If I run full speed I can't maintain it real long before I run out of breath. I can run about 1/4 mile in a minute and that is kind of where I have to slow down. I'd kind of actually like to at least double that but not sure there is any real point besides because I can and maybe somewhat better shape.
what about bad eff3cts to our heart and kidneys if we run for a long period of time?
i always enjoy running, i love it
i remember in PE at school our teacher made us do 6 laps around the school and i came first and near the end i was running really fast without any energy i legit tired but i ran soo fast i have no idea how i did it
thumbs up for using the international system. Interesting video :)
has there been developments with synthetic ivory ? would synth ivory fix the black market ?
Thumbs up for the HP reference.
I love to run, the feeling of the wind in your hair, and just eating distance. However, for how much I love to run, I love swimming even more. XD
+Aaron Brown PLOT twist you have no
Hair
LOL
fuck the wind, that shit is hard to run against smh
I suffer from chronic depression. Endurance exercise (running or bicycle riding) of an hour or more is the only thing that makes me feel good.
I never thought about it as a high but I do enjoy a long run
Serving in the U.S. Marine Corps, I loved to run. That kinda got side tracked after getting blown up serving in Iraq though. I miss the endorphin's I used to get while running.
USMC is the whole reason I’m watching this video Semper Fi Marine.
i dont get a runners high but i feel really cool when i run with weights and take them off i can jump much higher and run much faster
It may be that different people can oxidize sugar more or less well.
I don't like to much to run, but never ending long walks are great !
