About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations).
When you HEAR, accent, pronunciation, body language comes in the way. When you LISTEN , nothing else matters.
Train. Most important thing is how well your heart rate recovery 1-2 minutes improves. Can also show overtraining as well as your resting heart rate. You can stress your heart more than you think if you don't know your own limits!
I used to do HIIT Sprint sessions 3/week before i got injured. It was awesome, but very tough. Pushing yourself hard every workout session can feel draining. Afterwards though i felt amazing. I think you have build up your physical fittness before attempting HIIT.
You should definitely have a strength base if you want to do HIIT effectively. Doing 100s of burpees without strong shoulders and core for example will get you injured. In your case, for sprinting workouts you want calves and quads developed first. This can easily be done with 1-2 strength sessions a week for those specific bodyparts.
For those who have heart problems, please consult your doctor before you attemt to do HIIT.
i would not do 3 HIIT per week; 1 to 2 max.
Incredible video!!! I train really hard and am very fit and very very happy 😃
HITT sessions have been around since Ancient Rome. Seneca the younger (philosopher of stoicism) talks about doing them when he had little time.
There was a presentation on the BBC that demonstrated how a short burst of intense exercise for 1 minute, three times a week can change the way the body store fat. I'll try to find the video and post it here.

Thanks for finding this.
No problem.
excellently presented. important info
Great content - congrats on the presentation!
Thanks for your hard work
Excellent info! Thank you. I started interval training today and I’m hopeful for changes.
How's it going
Hope you're still going strong!
@@karaliblick7887 thank you! I am! More weights with reps to fatigued, but some interval training in there, too.
@@GwenMotoGirl That's amazing! Way to go
@@karaliblick7887 thanks! I’ve been very active since I was 17 and I just turned 62, so I guess it’s too late to stop. 😆Thanks for your kind words!
high quality presentation
Very Good Talk. Thx a lot Ivind.
Hunter Harington sorry but this was not a good talk. Information is good but presentation was really bad.
Øivind Rognmo, interesting work you are doing, but 'SMC', good argument and well said.
I won't judge because I tend to do a lot of use of "eh, ah, euh" and I find your content more than enrichful. Besos miles 🤗💙
I go to orangetheory fitness… it is a perfect amount of high intensity training! Love it
Good suggestions Good for all. Anusorn T. - Bangkok Thailand
why would anyone give this video a thumbs down?...
yes
Thank You sooooooo much 🙏🤩🙏
This is essentially true but limited to his own bias, as exercise triggers the "Body's Stress Response", but triggering the body's stress response means turning on many genes. FOXO3, BDNF etc .... produces antioxidants that repair and rebuild the body. All form of "Stress" triggers a response ... i. e. Heat, Cold all benefit our immune system ...
70 Going On 100
I hope you are still alive and doing well, Carroll.
you need to focus the camera on the screen when the presenter is talking so that we can red the slides
VERY INFORMATIVE.THANKS, A LOT, SIR.
You can learn a lot by listening to experts.
great talk!
So training workouts around the 10min-20min mark with high intensity is the best for health?!
Stuff like bodywaight workouts (freeletics)
Good info!
Where can I find the studies he used for the presentation? Graphics and stuff...
fitness is a blessing from God🙏
lavi doxa
If God truly wanted to bless us he wouldn't make it so that we HAVE to exercise.
Do you mean highly intensive interval fitness training?
If you gave someone a Ferrari, wouldn't you take it away if they NEVER used it?
It's a blessing you create for yourself and carry it out yourself.
I did not know Matt Damon was from Norway
Alex CHAU lol 😅he so does look like Matt Damon 🤪
🤣🤣🤣 i think the same way
I used Unflexal handbooks for that.
bruh i thought that was matt damon 😂😂
Freeletics is great for HIIT exercises
Very true 😄
Good talk
Great reinforcement
Superb
I don’t enjoy high intensity e exercise at all, but clearly the research shows a benefit, even post exercise. It’s not just ”train more”, reap more benefits, but it’s specifically short duration, high intensity exercise. You don’t need to injure yourself, just push yourself beyond what is comfortable short periods of time, and repeat a couple times. Do this 2-3/week. On another day do low intensity zone 2 exercise for a longer duration. On another day, lift heavy things. Eat real food. Have friends. If in Norway, use a sauna 😂 That alone will help you stay alive. All the folks criticizing his presentation- I assume you can read the graphs? Seriously. Since when do all scientists need to be great social media presenters? And how many languages do *you* speak proficiently? Give the guy a break.
Depends on which part of the brain 🧠 motor cells or neurones?
The fitness questions they have on their website are highly inaccurate. They said my vo2max is 57! I'm no where near that
My question is, knowing that being fit and active extends your life, why don't more people do it?
Docinaplane because it takes effort
Lazy
How do you spare your knees and joints in the long term? I haven't seen many 50+ / 60+ doing hiit. I enjoy it full when I practise it but I would also like to keep it safe on the long term but I guess I found the solution myself 🤗💃☉
Healthify My Life eat a lot of omega 3 for cartillage repairs from salmon and avocato and butter
make subtitle please.
He found the bus driver didn't live as long as the conductor? Wow!
The comments below ? Too many supposed experts. This is just common sense now that we understand it.
Except the only type of exercise to show significant neurogenesis is aerobic for long durations. High intensity showed hardly any change at all. Hopefully more studies will be done on HIIT in this regard. Would be nice if further research shows improved in this area.
Good talk, but why does it look like the first letter of his name lost a sword fight?
But where is the link to the website?
www.ntnu.edu/cerg. He gives this address at the end of the talk
So, training is good for you? Got it.
It's why we're doing CrossFit! :D
Important talk, very important findings, poorly presentet though. Still motivating to keep exercising.
+egorka2201 Important comment, poorly presentet.
+strewf Give him a break. He's a scientist using a second language. Why expect him to be a great public speaker also?
***** My comment referred to egorka2201's comment.
It's always astonishing to hear people criticizing a man or woman who has learned how to speak English, a very difficult language, with flawless grammar when they can't even write a sentence with the correct structure, i.e., "Still motivating to keep exercising."
I'm super impressed with multi-lingual people, especially those who present on such technical subjects. Øivind Rognmo is brilliant.
This talk was uh interesting, but uhh very uhhnoying
at least one important thing is missing in this presentation, and that is mitochondrias, which are very important to build a balanced picture of training. oxygen uptake is one variable in the equation, but then one also MUST consider the effects of training on mitochondrias, fat oxidization vs glucose processing by muscle fibres, hydrohen ions, lactate acid, and all these variables affect training in reciprocity. overall: somewhat superficial study/presentation.
A scary thought. Oh but to motivate
I recently read an article by a doctor that HIIT is in fact causing many deaths as this tends to turn plaques into blockages due to the increased flow of blood. HIIT is it seems safe only for athletes, for the rest one should exercise keeping the heart rate within decent levels.
This video really starts at around 13 min point to say what it has to say, the rest is just rehashing. He did ok, just needs to stand still when talking, the talk isn't an exercise session. One thing really bothers me, that's with high intensity you run high risk of rupturing the plaque found in so many people these days. I believe you need a non-atherogenic diet for at least a month before you start in on exercise, even moderate. That would be a whole food plant-based diet. Otherwise you raise your risk very significantly for a heart attack or stroke. Studies from 1975-80 on 5000 people in Rhode Island showed those who jogged (moderate to high intensity) got 7 times more heart attacks than those who watched TV. Why he thinks exercise, esp high intensity, is good for all of us, probably has to do with his own age. It's true that sedentary people versus active ones have more risk, but high intensity exercise is more than just being active, such as walking, etc.
Good talk but I don't agree with vo2 being defined as "fitness level"
+Andrew Waters
Why do you not agree with vO2 max being defined as a "fitness level"?
(I am studying for my personal training certification and want to learn as much as I can from as many different sources and backgrounds as I can be exposed to.)
VO2max is used as a MEASURE of one's fitness level, it's not a DEFINITION of fitness level, nor is he using it that way. Open your ears and pay attention.
So the guy has an accent that might sound funny to some. Have you thought about how you would sound speaking another language before judging him?
HIIT is not for everyone, and age is the factor. Everyone has to have a 72 hours of rest period. Continuous strenuous exercise will harm you more than good.
You also NEED to have a strength base for doing HIIT effectively or you're going to injure yourself. Smashing 100s of burpees every workout (as an example) is dangerous if you haven't built strong shoulders, chest and core yet.
All training is interval training...
+Sam Callan Well that's just wrong.
I'm going to be very honest so listen up. I have consistently worked out for 1 to 2 hours a day/3-4 day a week. The most weight I have been able to keep off is 12 pounds. So, since 1994 to present without proper dieting most times, I kept 12 pounds off. I stopped working out completely this summer when I injured my back unrelated to exercise. My asthma has also worsened since covid because of stress and weather changes. I gained 12 pounds back and started eating healthy and the weight is coming back off. I have exercised with 10 pound free weights for 26 years coupled with cardio and it just didn't make much of an impact. Your genetics and pre-existing conditions will determine how long you live. If you take all prescribed medications for your conditions, your life span will increase. Low to moderate exercise like walking is much better than HIT. Didn't they put out a warning about intense exercise causing heart problems? I'm going with my nearly 25 years experience. Exercising is not all that but dieting is.
It's quite difficult to follow this talk... that guy should have asked someone else to talk for him.. that's my opinion by the way
Why should he have to dumb everything down for you?
-Danny Lenovo- or just do it in *whatever language he knows best*.. _Slovak??_. Then we can go learn his language . -Get it?-
I’m listening 1,5x speed, and understand clearly, and English is my second language...
Nothing new here. I only care if my ambitions to be the top level gold medal on gymnastics rings is going to cost me lifespan. Not answered here.
Pretty sure diet is a bigger risk factor for disease. Exercise may be the biggest non dietary lifestyle risk after smoking.
How
Check out nutritionfacts.org. Dr. Greger has a great channel on youtube explaining a number of health and nutrition topics but the bottom line comes out to one thing: the detoxifying and calorie burning effect of exercise cannot compete with poor diet. Your body cannot compete with refined sugar and tons of animal products, no matter how much you train.
Exercise is Stress ... and the body's response to stress is far better at repair and rebuilding than anything else. Leave it alone to function. The body runs much more efficiently on Ketones than carbs ... your diet will have set up this mechanism, therefore bad diet - poorly prepared, good diet - prepares the body to activate FOXO3, BDNF genes and the pathway is just now being understood ...
This guy only tells part of the story ...,
70 Going On 100
Physical inactivity is 4th leading cause for mortality in the western world only behind cancer, heart disease and stroke
Totally agree.
impressive... they found the Norwegian with the worst English pronunciation at the university...
eh eh eh eh uh uh uh eh eh eh uh uh eh
yeah its sometimes hard to follow, but then you can speak fluently norweigan and can explain studies in that language?
NocholasP I get what your saying but those are word whiskers . He uses it so much. Hard to listen to.
get to your point already!
Hard to understand because of the heavy accent
Heart rate formulae are notoriously poor.
The bus driver wasn't "inactive" all day, he was driving a double decker bus, without the aid of power steering. I suggest the speaker tries to drive one before making such inane remarks. Meanwhile, the bus conductor was {gulp!} walking and sitting.
Listening to this was like listening to reggae music.........stop go stop go stop go stop go..AAAAAAGGGHHHHH!!!!!!!!!!
Great information............TERRIBLE DELIVERY, MOST ANNOYING!!
Torture listening to this unprofessional. Hire a speaker stay next to him on stage , nod your head, leave your ego of presenting your research besides its not even a breakthrough so chill . ciao
How many languages do you speak buddy. Also show me your degree please.
+RenaissanceMaxx 3 Languages and I master all of them.
+RenaissanceMaxx this is the best reply a stupid person could come up with "Show me your degree" ?
So you that's what is all about?
you are empty holding a degree, according to you that's the only thing that matters.
Domestic human thats what you are
My point is that if your slamming the slight language barrier between the presenter and the audience, you clearly dont care too much about the content he's presenting. Its still very easy to understand every point he's making, and I'd rather he spend more time on research than mastering how to explain it to ignorant people or otherwise (like myself) who speak only english.
+RenaissanceMaxx Mate you've proven my point , its all about the content so hire a professional speaker to deliver it.
further , I have ADHD and I lose my patience rather quickly , on the positive side I can hyper focus at times , I studied and understood quantum mechanics and quantum physics in less than half a year. in conclusion that guy sucks ive seen better. search for Guy Winch TedTalk , good luck
Needs to learn to speak English before giving a presentation in English language.
Most of these ted talks suck.
This talk is impossible to listen to
torture to listen to but information is gold. he should read a public speaking book before doing a TED , first impressions matter
Tell us something new... This information is common sense.
Also, the guy doesn't seem to confident and knowledgeable about his speech.
this is norwegian english, so pathetic, I hope he is not making it up, hvordan kan du snakke sånn?? Erdu helt seriøs nå, ellendig :P
+Raw Powerlifting Strength - how's your Norwegian?
perfect
*elendig
His English is sooo bad, makes me cringe.
TheAtheist like that matters you tool
We would not be stupid enough to go OR visit a VERY LOW STATUS country that don't have their shit together, it's like saying, "Yippy I'm going to Prison tomorrow!!!"
Norway have highest human development index of all countries.
I'm not a native English speaker, but I understood his speech well.
yo! u can turn on caption dude!!
Couldn't listen to this guy for long.
Presentation was disgraceful.
You can learn a lot by listening to experts.
