Top gear style swim v bike v run. One of you doing each. Maybe long lake swim v fell run v big bike loop all racing to same point. Would take some thinking about to get roughly equal times. But some clever editing will sort that. Think lake district would be perfect terrain
Altitude mask has got to be the worst idea ever for burning calories. Restrict oxygen, which is needed for aerobic respiration to burn more? Wrong, just exactly wrong. You need oxygen to burn calories, and you need to exhale co2 to get the waste out of your bloodstream so you can keep the process going. It's actively preventing you from achieving your goal. The heart rate monitor may be fooled by the high heart rate (due to poor blood chemistry), but you won't actually burn as many calories as you would have otherwise.
Exactly! This is total non-sense...most likely blood is under-saturated of oxygen with that silly mask...its just like driving a car with the handbreak on...
Yea...I think the aim here was to put a video out? Regardless of how bad/non existent the science was. Pointless really, obviously Heather being slower and smaller can't burn 1000 calories as fast like..
I dont get it, isnt it the case if you are restrict the oxygen level, your heart have to push at a higher rate to get oxygen in the system? I would think, there is a higher nees in energy because of the higher heart rate?
Oxygen is used in the process of producing energy so ofcourse restricting it will restrict energy production i.e calories burned. Try holding your breath for an hour I bet you don't burn many calories at all.
Surely it would increase calorie burning due to the fact less energy would be produced per mole of glucose due to the fact that there would more anaerobic respiration occuring which produces less ATP per molecule of glucose and therefore more glucose would needed to be broken down to produce same amount of energy?
I'm not convinced by the theory that running overheated would burn more calories. To me it is quite counter-intuitive in fact. The equivalent on the bike would be riding on a turbo trainer without a fan, you overheat and the heartrate spikes, but you can push much lower power than you could do with sufficient cooling. Wouldn't the higher power result in more calories burnt? Maybe you can do some testing in a lab, measuring the exhaled air to determine how much calories have actually been burned. It's not your heart that is burning the majority of calories (that is, using the glucose), it's your muscles! While heartrate is an indicator of how much your muscles are burning that logic does not work in the other direction. Drinking coffee to burn calories is like wiggeling a pedometer and then estimating that you ran about 10 kilometers. That's why you use threshold power and relate it to a certain heart rate in advance to calibrate the device so that it can estimate the actual power output via the heart rate.
It's a terrible idea. The overheating might work for short high intensity training or low intensity training with large fluids intake, because the body would have to expend extra energy to maintain temperature(i.e. sweat), however sweating is actually very energy efficient, but heat dissipation is a major problem for the body. So you end up with muscles not being able to burn as much energy because of overheating... and a lot of other risks. It may cheat the monitor, but it won't burn the calories.
It would be smarter, in terms of calorie burning, to actually run naked. For your metabolism will still working in order to regulate temperature using energy while you're resting.
running with less clothes should actually help because our muscles have 30/70 mechanic/thermic efficiency, so burning 1000 calories will give your body the heat of 700 calories, with extra clothes he'll just overheat
It doesn’t. Running naked would burn more. Like you said the reason he “burned” a lot is because the heat makes his heart rate go up, making the watch think his doing a hard effort.
Correct. Elevating heart rate is no indication of calorie burn. You should measure power. Increased heart rate is also a sign of heat management rather than burning calories.
Would love to know the total distance each of you covered during the challenge! A rule of thumb that a lot of people seem to use is that running burns approx. 100 kcal/mile, regardless of pace/HR/etc (though varying with body weight) and it would be interesting to see if this lines up at all with your challenge!
I doubt that heartrate is an accurate measure of power output and thus enrgy consumption - too many influences on HR that are not power-related. You better repeat it with spirometry.
Yeah people have panic attacks and they still don't burn a lot of calories even though their heart rate reaches 150 sometimes! Heart Rate isn't a accurate indicator of how many calories you burn!
To increase the total calories you burn in a fixed time and fixed incline, you can: (1) increase your mass/weight by carrying a full backpack. (2) increase your speed. If instead the speed is fixed, you can maximize the incline/slope of the treadmill.
For the physicists/engineers here, in first approximation: dE = F ds ~ m g ds = m g dx / cos(\theta), and the rate is dE/dt ~ m g v / cos(\theta) , where: E is the energy, m is the mass, g is the gravitational acceleration, ds is the change in position, \theta is the angle of the incline, and v is the average speed at which you run.
OH MY GOD I LOVE YOUR CHANNEL SO MUCH!!!!!!! In all seriousness, the 'Presenter Challenges' do help remind us(me) that you are actually still doing it - I know that sounds wrong, but there are so many shows that are difficult to relate to because you're being lectured at. Episodes like this, for me at least, show that (although nowhere near your league) I'm striving for the same thing... Thank you.
Yes someone finally had the same issue as me. I live in Brisbane. I try slow down but heart rate doesn't go down a significant amount (maybe 190 to 185) which for the amount I slow down isn't worth it. At least someone who has a high heart rate shows once it is up it is hard to bring down
Yeah it's called decoupling I believe it happens even in top athletes. Theirs nothing to worry about. It does get better but you'll hr will always struggle to get back down until you stop
Could we all take a moments silence for the reduction of the sugar content in Irn Bru. Once a nations pride and joy, now a bubblegum flavoured water. RIP my hangovers will never be the same. Xxx
Watch algorithm is basically going to treat 195 BPM like a VO2 max run that never ends. Doesn't mean you actually burned more calories, just that the watch says so.
In a challenge of "burning" calories, restricting air seems like a bad idea :) just my thought. So now u just have to do it all over again while swimming and cycling :)
its not simulating "thin air in higher altitude" at all - also less oxygen slows down the max energy that can be released by the use of oxygen from breathing. all it does is add some resistance to your breathing and as such might improve the mechanics of breathing...
John Teal that “simulates xxxx meter altitude” is all marketing bollocks. These masks don’t make the air you breathe thinner, they just restrict the amount of air you breathe/make your lungs work harder to inhale. Your body doesn’t get an EPO like effect, only your lungs could benefit from having to inhale harder
after a run i can easily slam down 1,800 not even an exaggeration at all. yesterday i had two pieces of bread with a THICK layer of peanut butter on both while i was cooking. it was probably close to 1,000 calories. then when i was finished cooking i ate 250 calories of beans and lentils, 200 calories of rice, 200 calories of eggs, and 300 calories of cheese
This should have been called who can cheat the watch the most. It's hard to believe athletes that benefited from proper training could come up with such misguided ideas. Yes, running in hot/ high/ humid environment is difficult, but not because it actually allows you to work the most. When you don't have the oxygen, your muscles can't do the work. And when you're overheating, your body has to pull back, you know, to prevent you dying. Heat is the product of energy "burning" and it has to be removed because our bodies have temperature limits. If you can't remove the heat, you can't burn the energy. Good cooling is prerequisite for maximum efforts. It's like thinking your car will have high fuel consumption if you remove the ventilator or block air intakes. No, it will just overheat. Yes, your body working hard to supply oxygen or shed heat will surely increase energy consumption of those systems (like heart using more energy because it has to pump more), but it's actually limiting you and it's not a very bright idea to stress your body like this unnecessarily. And if Heather likes her coffee with sugar, I wouldn't be surprised if she drank more energy than burned by increasing heart rate. Your heart pumping faster won't cause your legs to suddenly become less efficient. And I imagine your legs burn way more energy than your heart. However, it would never occur to me that spiking my heart rate could have positive effect so no reason to look such things up. Heart rate works as an indicator as long as it was increased by exercise. If you increase it by other means, you're just messing with the calculation. Which is, after all, the argument for power meters. I was expecting to see one of you trying proper high intensity intervals. They're well known for efficiency. It would be interesting to see how it compares. Generally, if you want to burn energy faster, you need to use more muscles (which is why e.g. rowing is pretty efficient), or you need to up the intensity. When I saw the title, I was like: What kind of nonsense is this? A thousand calories is nothing. I just had a piece of a chocolate bar that had 38 grams and 860 kJ. That's about 205 thousand calories. In 38 grams. But then I realized you're British and you Brits like to be different. :-) Actually, a milion calories is a pretty big meal. Half the recommended daily intake I believe. If you eat actual food. Yes, in chocolate, cookies and such, it's not that much. Under 200 grams.
sweating doesnt playing any role to what calories you put out..its a cooling mechanism for your body..even if u run at -10 or -15 degrees and u cant get sweatt but u can still burn the calories depending on the exercise and intensity..what i dont know is,if we need to burn calories for that cooling mechanism if this is correct..then you have to put the same guy run to a cold place to a hot place ,at high altitude and low altitude..then you know what is the fastest way.
This video only demonstrated nescience. All of the presenters found ways of tricking a computer program, not of doing the work necessary to burn the calories. There is no short-cut to that.
I wonder if they wore chest straps. I know my garmin can be way off sometimes on the heart rate when running ( its exact when not moving around ). That false reading would skew all the other stats, like calories
If you are in cold like minus ten celsius in summer clothing. You are start shaking a lot. and then you burn calories more without do anything. Hertrate not rising much. heart rate don´t tell you how much colories you burn
The only use for these measurements are in relative terms to your other tests. There no accuracy in the heart rate monitoring, or other parameters, as well. That's how I personally find benefit in such measurements.
Hiya, I love you guys. I always look forward to your next video. I love too run and I have a few half/marathons in the summer. However, I have always found hill runs the hardest. Is there any advice to help. X
Putting on multiple layers of clothing doesnt make you burn calories...it makes you sweat and lose water, which is losing water weight, not burning calories.
Looking at Fraser’s tactic... could you guys explain and give advices about running overheated on triathlons? Usually half and full distance triathlons run segment takes on those hours where the sun bites. I struggle on overheating knees for example
Miguel Sáez Do some google research on heat acclimatization and the use of sauna sessions. There is quite a bit of well documented research about how effective and useful it can be to prepare the body and mind for a hot race
Sigh. I'm going to try to be nice and not use derogatory words here, but this was dumb. Just because something is harder doesn't mean it'll burn more calories. Put a thumbtack in your shoe and it'll be really hard to run, but you won't burn more calories. To burn more calories, you have to DO MORE WORK. So ... running with a parachute - yep. Running with a weight vest - yep. Running up hill - yep. Wearing more clothes - not really (just the weight of the clothes is slightly more work). Reducing the amount of oxygen - will REDUCE the amount of work you can do. Intervals - over all, you'll burn fewer calories than a steady run because your average work rate, once you include the rest periods, is LESS than the average work rate of a hard steady pace run. You can also increase calorie burn a bit by increasing heat production (wearing more clothes doesn't increase heat production, btw, it just reduces your ability to shed heat). So caffeine or thyroxine will cause some increase in BMR and thus increase heat (calorie) production. Seriously. Do the math (or, in your case, "the maths" 'cuz you're in the UK).
despite its name, it is not an altitude mask. studies have proven that it does not simulate altitude at all. All the mask does is provide airflow restriction and thus only strengthening the respiratory muscles. Altitude decreases the partial pressure of the air and so thus "less oxygen", restricting the airflow still allows for the same amount as oxygen to be inspired due to no decrease in the partial pressure of the surrounding air.
That altitude mask is perfect for running outside these days :-) Now i wish i had one... Also, am i the only one who finds a striking resemblance between Heather Fell and Hannah Fry? They even have the same initials.
Lettuce might be like 50kcal. Big piece of cake (like 200g) can easily be 950kcal though. Those sugar/fat bombs are one the most calorie dense foods out there.
here in the U.S.A'murca, I walk an hour and 15mins. i cover 5(14-16minute miles) and burn 950 calories there boutz. what kind of calories do you guys have in England'Land that it takes 13k (8'ish miles) to hit that marker?
When I want to lose weight quickly, I wear I layer with plastic. A cotton T-shirt to absorb the sweat, then a black plastic bag, then a tight fitting top to keep the bag from making all that noise then a large T-shirt, then a jumper. But I do my running at 05:00am in the morning. Do static stretches. Then a good warm shower makes my body feels good ready for the day ahead.
AirsoftAfterHours it really depends on your weight. These are skinny and light people. If you are a 400 pound man, you can burn 500 calories in 30 minutes with a moderate effort in a gym but a 105 pound woman would need an intense effort to even get that done in an hour.
This is all assuming the calorie burn is accurate on a watch. Also, I don't think they were really running threshold if they could talk to the camera fairly casually.
@@heatherfell_oly the run seemed brutal, at least from my couch while commenting. PS: my sarcasm aside, thanks for the great video, running is my weakness and GTN really help my form/motivation :D
Excellent example showing what fighting heat is more calory demanding than fighting cold. Unless that cold indeces shivering. Whilst shivering, you might probably burn calories the fastest way it could be possible: good luck to hold it for more than 5 minutes, thouch it might be worth 1hr running. Here are lifehacks for fast burning: - shiver - sweat a lot (including in Sauna or even in a basic hot bath) - skip a meal once in a while. It's also good for fat metabilism boosting. And if you donate those money saved on food for a local (global are cheating) charity, may God bless you in all your endeavors. - HIIT sessions that cause your skin oxigenation drop not just by the end of the session, but for hours... and hours. That will ensure that you are burining calories after the training, as HIIT advocacy claims.
I lost ten stone running with a sauna suit and thick layer of clothes took around 8 month but was insanely hard work and now I just run with shorts couldn't go back lol
I don't understand why elevating the body temperature ot creates a greater calorie burn. Of someone cold explain me i would be pleased. In my opinion, increasing the body temperature is not a good idea, because your muscles have an optimal temperature to work, so of you mess up with that, problably you will get less calories burned
Uhmm if you have lots of more calories, yes it technically does burn calories, but most of the "calories" actually burned is only you sweating and losing water

Put a thumbtack in your shoe and it'll be really hard to run, but you won't burn more calories. To burn more calories, you have to DO MORE WORK. So ... running with a parachute - yep. Running with a weight vest - yep. Running up hill - yep. Wearing more clothes - not really (just the weight of the clothes is slightly more work). Reducing the amount of oxygen - will REDUCE the amount of work you can do. Intervals - over all, you'll burn fewer calories than a steady run because your average work rate, once you include the rest periods, is LESS than the average work rate of a hard steady pace run. You can also increase calorie burn a bit by increasing heat production (wearing more clothes doesn't increase heat production, btw, it just reduces your ability to shed heat). So caffeine or thyroxine will cause some increase in BMR and thus increase heat (calorie) production. Seriously. Do the math (or, in your case, "the maths" 'cuz you're in the UK).
despite its name, it is not an altitude mask. studies have proven that it does not simulate altitude at all.
All the mask does is provide airflow restriction and thus only strengthening the respiratory muscles.
Altitude decreases the partial pressure of the air and so thus "less oxygen", restricting the airflow still allows for the same amount as oxygen to be inspired due to no decrease in the partial pressure of the surrounding air.
Fraser i love the comment on Heather and mark
Result: 13:40
Average 195 HR?! I doubt that!
That altitude mask is perfect for running outside these days :-) Now i wish i had one... Also, am i the only one who finds a striking resemblance between Heather Fell and Hannah Fry? They even have the same initials.
The idea that some lettuce and a slice of cake is 1000 calories is just laughable.
Lettuce might be like 50kcal. Big piece of cake (like 200g) can easily be 950kcal though. Those sugar/fat bombs are one the most calorie dense foods out there.
Some cakes have a surprisingly huge amount of butter in it, so although 1000 for a slice might be too much, half that on a fat slice would not be hard
@@silv3rArrow depends on the slice. i slice it 12 inch at a time
@@TheObeseDuathlete 12 inch diameter? 😁
I love you guys !
11:57 heather, that's somehow worse lol
A roll of haggis...that's a real thing in the UK?? :) If you are willing to do that, go all the way with some lutefisk too!!
here in the U.S.A'murca, I walk an hour and 15mins. i cover 5(14-16minute miles) and burn 950 calories there boutz.
what kind of calories do you guys have in England'Land that it takes 13k (8'ish miles) to hit that marker?
This very interesting. Great episode
Thanks.
Why not carry something heavier ?
How many minutes did u guys ran
How is only 13k the biggest run session Heather's ever done? Does 'run session' mean something specific?
Will GTN do a beer mile?
Check out our Kona highlights video, Mark has already had a go!
You can see Mark have a go here 👉 gtn.io/GTNKona
@@heatherfell_oly the people want to see you pound a couple brews and do a beer mile too!
@@Dnman218 Oh no :0
Some people just want to see the world burn...calories.
I think it would have been better to use a weighted vest over an altitude mask.
Is that altitude mask an easy way to train at altitude without going abroad?
When I want to lose weight quickly, I wear I layer with plastic. A cotton T-shirt to absorb the sweat, then a black plastic bag, then a tight fitting top to keep the bag from making all that noise then a large T-shirt, then a jumper. But I do my running at 05:00am in the morning. Do static stretches.
Then a good warm shower makes my body feels good ready for the day ahead.
I hope you're joking, right?!
Kickboxing would be my choice
I would’ve just used a weight vest, that would burn more calories
I spent 50 minutes on a ski stepper machine and it said I burned 650 calories, I'm pretty sure the machine is wrong lol
AirsoftAfterHours it really depends on your weight. These are skinny and light people. If you are a 400 pound man, you can burn 500 calories in 30 minutes with a moderate effort in a gym but a 105 pound woman would need an intense effort to even get that done in an hour.
@@blue-pi2kt
That makes a lot of sense! thanks for the information, it's amazing how our bodies become more efficient and compensates for survival! ^^
mark looks vary smooth when hes running..im not jealous (much)gr8 video guys thanks
Cheers 🙌
I ran just over 9 miles yesterday and burned 1001 calories. Can I do it faster…? Challenge accepted
Great - well done!
This is all assuming the calorie burn is accurate on a watch. Also, I don't think they were really running threshold if they could talk to the camera fairly casually.
1000 calories? GCN did 10 000! You make us triathletes look like amateur ;)
Sadly we didn't have all day and think our bodies would be broken if we purely ran for 10K calories.
@@heatherfell_oly the run seemed brutal, at least from my couch while commenting.
PS: my sarcasm aside, thanks for the great video, running is my weakness and GTN really help my form/motivation :D
This doesn't prove that calories were burnt.
Faster heat rate doesn't necessarily mean more calories burnt.
This is misguidance.
You guys should try to down load on apple strore the app called calorie munch out .... its great for the entire family
Fun video guys!
Thanks 🙌
How does the watch know you are wearing a mask
Excellent example showing what fighting heat is more calory demanding than fighting cold.
Unless that cold indeces shivering. Whilst shivering, you might probably burn calories the fastest way it could be possible: good luck to hold it for more than 5 minutes, thouch it might be worth 1hr running.
Here are lifehacks for fast burning:
- shiver
- sweat a lot (including in Sauna or even in a basic hot bath)
- skip a meal once in a while. It's also good for fat metabilism boosting. And if you donate those money saved on food for a local (global are cheating) charity, may God bless you in all your endeavors.
- HIIT sessions that cause your skin oxigenation drop not just by the end of the session, but for hours... and hours. That will ensure that you are burining calories after the training, as HIIT advocacy claims.
i had a bike ride in summer kit(no wind jacket) in hard wind and 2c there is no problem going that cold if you are used to it
This is such a professional runner channel - WHY HAVENT IVE SEEN YOU GUYS BEFORE! :O
Meanwhile on GCN they go for 10,000!
shoutout to all us ladies that gotta work a lil harder to burn off those twinkies ;D
I lost ten stone running with a sauna suit and thick layer of clothes took around 8 month but was insanely hard work and now I just run with shorts couldn't go back lol
195HR for an hour?? Is that even healthy / safe?
You´re filming this video in Prague, right?
Haggis and Iron bru for Fraser 😅
Was the winning method to wear "extra" clothes or to be sick? Seemed like it was the extra clothes but kept harping on him being sick at the end?
The one's that burnt the most calories gotta be the cameraman
He didn't run it all!!
I don't understand why elevating the body temperature ot creates a greater calorie burn. Of someone cold explain me i would be pleased. In my opinion, increasing the body temperature is not a good idea, because your muscles have an optimal temperature to work, so of you mess up with that, problably you will get less calories burned
I think carrying weight or adding elevation would have helped much better.
Uhmm if you have lots of more calories, yes it technically does burn calories, but most of the "calories" actually burned is only you sweating and losing water
2:46 is Fraser a giant or is that a miniature bench?
Add weight, go up steep hills. Job done.
I was thinking the same thing. It would've been nice to see a fourth person running incline intervals.
Just a10 mile run will do it. Less miles if your able to run it harder.
Did u all sweat? I see none of u all sweat after burning 1k calories..
threshold run on an empty stomach would be my guess
where could I get those cool GTN shirt?
