High-intensity physical exercise will boost your health: Øivind Rognmo at TEDxTrondheim 

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.

Incredible video!!! I train really hard and am very fit and very very happy 😃

excellently presented. important info

Thanks for your hard work

HITT sessions have been around since Ancient Rome. Seneca the younger (philosopher of stoicism) talks about doing them when he had little time.

Great content - congrats on the presentation!

Very Good Talk. Thx a lot Ivind.

Excellent info! Thank you. I started interval training today and I’m hopeful for changes.

Good suggestions Good for all. Anusorn T. - Bangkok Thailand

Where can I find the studies he used for the presentation? Graphics and stuff...

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 🤗💙

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.

I go to orangetheory fitness… it is a perfect amount of high intensity training! Love it

Øivind Rognmo, interesting work you are doing, but 'SMC', good argument and well said.

So training workouts around the 10min-20min mark with high intensity is the best for health?! Stuff like bodywaight workouts (freeletics)

VERY INFORMATIVE.THANKS, A LOT, SIR.

Thank You sooooooo much 🙏🤩🙏

high quality presentation

you need to focus the camera on the screen when the presenter is talking so that we can red the slides

Good info!

great talk!

why would anyone give this video a thumbs down?...

bruh i thought that was matt damon 😂😂

I used Unflexal handbooks for that.

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

Good talk

Superb

Very true 😄

fitness is a blessing from God🙏

I did not know Matt Damon was from Norway

You can learn a lot by listening to experts.

Freeletics is great for HIIT exercises

But where is the link to the website?

Great reinforcement

make subtitle please.

Depends on which part of the brain 🧠 motor cells or neurones?

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 🤗💃☉

The fitness questions they have on their website are highly inaccurate. They said my vo2max is 57! I'm no where near that

He found the bus driver didn't live as long as the conductor? Wow!

My question is, knowing that being fit and active extends your life, why don't more people do it?

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.

Good talk, but why does it look like the first letter of his name lost a sword fight?

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.

The comments below ? Too many supposed experts. This is just common sense now that we understand it.

So, training is good for you? Got it.

It's why we're doing CrossFit! :D

A scary thought. Oh but to motivate

This talk was uh interesting, but uhh very uhhnoying

Important talk, very important findings, poorly presentet though. Still motivating to keep exercising.

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.

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?

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.

All training is interval training...

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.

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"

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.

Pretty sure diet is a bigger risk factor for disease. Exercise may be the biggest non dietary lifestyle risk after smoking.

get to your point already!

impressive... they found the Norwegian with the worst English pronunciation at the university...

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

eh eh eh eh uh uh uh eh eh eh uh uh eh

Heart rate formulae are notoriously poor.

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.

Listening to this was like listening to reggae music.........stop go stop go stop go stop go..AAAAAAGGGHHHHH!!!!!!!!!! Great information............TERRIBLE DELIVERY, MOST ANNOYING!!

Needs to learn to speak English before giving a presentation in English language.

Hard to understand because of the heavy accent

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

Most of these ted talks suck.

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.

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

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.

His English is sooo bad, makes me cringe.

Couldn't listen to this guy for long.

Presentation was disgraceful.
