They forgot that in the weight loss test most of the sweat/water loss will stil be in the driving suit, they should have done the before and after weight without the suit on.

[@MaxPower-vf8kt]

Exactly what I thought. I’ve done 2-3 hrs workouts and my thin gear weighs a lot and can be rung out with sweat. The most I’ve ever lost is 6lbs, but I weighed around 145 Lbs at the time (with 142 lbs being my finishing weight, my starting weight that day was 148). I’d imagine the more you weigh, or the bigger you are, the more water you retain and the more calories you burn.

[@d4slaimless]

Same goes for the control test. They were wearing their bathing suits and their hair was wet. Should have dried out before weighing.

[@nitro8529]

Thats an American show... Theyre so ignorant that they didnt Look any further than America. This myth is Not even a myth. F1 drivers weigh before and after Race and weve already known that they lose that much weight in races. So Theres nothing to debunk.

[@svendtveskg5719]

True that. And besides, the driving they do, is only half as exhausting as a real race.

[@Lorijenken]

the manhole thing actually happened during the inaugural las Vegas F1 race were a sewer cap kept being popped out.

[@AndrewNiccol]

Not just Vegas, it happened many times in F1, like the first F1 in China. I don't know why Mythbusters can't replicate the result.

[@92xsaabaru-]

​@AndrewNiccol IndyCar probably wouldn't let them acknowledge the existence of other racecars. I would have loved to have seen them make their own "fan car" to replicate the results though.

[@clumsygarage1578]

I know that the new F1 cars have big, crazy diffusers, probably do significantly more than the car they tested.

[@RonPiggott]

It should not have been busted. It has happened. They just couldn't replicate it.

[@Wings_of_foam]

They drove a 2 seater with more weight and less speed and didn't use a real manhole cover or a sewer. So, they didn't copy the exact same environment.

[@phoenixmotorsport647]

The Weight "myth" still stands. All the fluid he lost is in the 3 layers of flame resistant material in hos suit, his balaclava, helmet lining and socks. For the test to count he would need weighing NOT in the race kit before and after. Secondly the video said his speed was 120 mph. An Indy driver would be regularly 200+ (I am however incredibly jealous he got to drive that thing though :) ). As far as the drain covers go just ask the Ferrari F1 team if they come up or not?

[@Pilsnor]

Yea the manhole cover thing is not a myth, it has happened a few times in f1

I read a long time ago somewhere that Bruce ("Three-Hour Concert") Springsteen and Michael ("Riverdance") Flatley could both lose 10 lbs/show in their heydays.

[@MrMarinus18]

Most of our waste we actually breathe out. Calories consist of hydrocarbons and our muscles use oxygen to convert that into CO2 and water.

Try that manhole cover myth with an F1 car and the car gets destroyed. It happens now and then on street circuits.

[@cas5447]

Funny to see that the whole manhole cover myth would be proven to work (at least in F1) just 6 years after this special aired when the Williams of George Russell would receive floor damage in free practice for the Azerbaijan GP by sucking up a loose manhole cover.

[@bobfels5343]

In F1 it already happened various times that a manhole cover came lose. Remember the one rocketing trough Russells car in Baku?

[@zigisamblak]

And Sainz got taken out in Las Vegas last year by a manhole cover.

[@vitruviuszhang5057]

It happened even earlier, DTM race in Shanghai in 2004

[@LMSCa18det]

I'm pretty sure the manhole cover can be lift with by a more ground effect type of downforce like 70 F1, and current F1 and Indycar. There is a reason they weld manholes at Monaco, Singapore and all street circuits. We even saw few years ago in Baku and last year Las vegas GP the damages that happend when those covers are not trully attached.

[@noregrets551]

I mean look at last years las vegas grand prix

[@jamesstatham]

The clothes will absorb a lot of the perspiration and they were weighed in the clothes. Reg man hole cover myth, it’s more plausible with an F1 car… especially the lotus 79 which was banned for its ground effect floor.

[@Jvk1166z]

i feel like the flat aerodynamics of that plastic manhole cover could have fucked the test up, there's gonna be a lot more turbulence going over something textured like a manhole cover, the air will have a harder time moving over it so it might get sucked up more. source: i'm a commercial helicopter pilot so i have significant training on specifically aerodynamics

[@gabrielv.4358]

Also the "Bueiro" cover in the water test was dragged out by the water, with completely different pysics than air

[@Dmytri206]

The 10 pounds is from driving, heat, etc. because the throttle and brakes itself are heavy, plus the the fact they are going 200 mph++ and the g force on the neck, so basically they are also athletes ( I only drive go kart and it is painful)

[@pindadopje0162]

Just look at Baku 2018 I guess George Russel in free practice wrecking the Williams over a loose drain cover. Or the last vegas grand prix

[@MetalHeadReacts]

The manhole one has happened numerous times in F1... it's been seen live on camera, so we know this one to be true.

[@gturner38]

So who's more likely to get the weight loss "myth" right, the drivers and physios that focus on hydration for races 20 times a year for their entire professional lives or a TV crew doing a segment?

[@nevergetagooduserid]

the car has also laid down a lot of rubber which will give more traction with every run they do

I also thught they might have looked myth that an F1 car has so much downforce it can be driven upside down (underneath a bridge).

[@ExMachinaEngineering]

Ask Carlos Sainz Jr. what he thinks of this myth... By the way, there's more suction under the sidepods instead of the center of the car. Large difference.

[@simotast4641]

120F in a sauna is way too cold. It's almost that much before i even start a fire in the heater. Proper sauna temperature is closer to 200F or hotter. In my opinion. 😁

[@atkelar]

What would be interesting to know is how much of that sweat is still in the overalls... i.e. they should have taken the weight (almost) nude before and after. I suspect there's quite a bit of sweat in that outfit right after the race.

they could have weighed an actual drived before and after the race instead

[@trashgamer3318]

[@labhusky3]

I guess hindsight is 20/20 but they should definitely have tested without the suits. That plus they forgot to mention that the guys were exerting maybe 50-75% the effort of the pros in an open wheel race car. Has anyone seen the weigh in numbers from F1? I know they have a drink system but I'm curious now

[@pengu1139]

Around 4kg on average maybe more in places like Singapore and in the middle eastern races

[@aidananstey9848]

Exactly it was like comparing someone who walked a half marathon in 3hrs to someone who ran a full marathon in 3hrs.

[@FungiGuy195]

This was so funny to watch haha. And painful at times. If they wanted to know if drivers really lose 10 pounds, they should've just checked the data of the governing body of indycar. They keep track of these things. At least in F1, the FiA does it. Don't know if and who in indycar does it. But it would surprise me if there weren't any data. Not put a guy in a car who drives 1/3 the speed of the actual drivers. This isn't scientific. Edit: Continued watching and holy hell. They think putting these 3 clowns in roadracing cars around willow springs for 3 hours, would be the same as driving an indycar for 3 hours. I can't man Edit: They acknowledged it. Still, why even run around willow springs haha. I guess they wanted to just have a fun day.

The most physically demanding sport is rugby with motocross placing a close second. On a warm (not hot) day pro motocross riders can lose 10 lbs in a single race. I lose about 2 to 2 1/2 lbs per hour pushing pretty hard off road (cross country?) but not actually racing.

[@wingerding]

I think im safe in assuming that professional marathon racing is the most physically demanding sport.

[@joe125ful]

I thing F1 is very close too because you have high mental stress too,keeping very high speed,keeping brakes/tires warm,defend or push to win. Ever heard about combinated challange too? I forgott name in english you swim,run,sword play,horse race and shooting on targets. You need to know loots of things instead of one thing.

They go from a standstill to 300mph in 3 seconds flat and within 1/8 of a mile, meanwhile jet dragsters with the same power output take 5 seconds flat to hit 300mph and it takes them twice the distance to get there too (1/4 mile).

I once did a solo 100-mile bike ride, and, knowing I'm a heavy sweater, I decided to weigh myself before and after. I stepped on the scale wearing my backpack with all my water and food for the ride, so I was accounting for intake as well as output - all the food and water either went into my body or stayed in the backpack. If I wasn't burning calories or sweating, I would weigh the same after the ride. I lost 17 pounds (just under 8 kg). I would estimate at least 15 of that was water weight.

[@trumpwatch9700]

Just before the 5 min mark the announcer claims that these (formula one) are the fastest race cars in the world. False!!! Nitro top fuel dragsters travel up to 339 mph within 1000'. That's 110 mph faster than the 240 mph these indy cars go. Top fuel dragsters are the fastest racecars in the world. There is a faster category & that's jet powered - salt flats cars. But they are not technically race cars as they are not in a race when they run. They are looking to get the land speed record - which is a contest - but hardly a race as there's nobody racing against you when you go for a land speed record. It could be several years before a top speed is contested. But it's never contested by conducting a race between 2 or more cars. It's just test of a speed record. However if you want to call them race cars anyway the these people on Mythbusters are lying twice - not just once - because there are 2 categories of cars that go faster. Way faster in fact. So I busted a myth right here that these guys are still believing. Someone should have a mythbusters - buster to challenge their lies - er rather "myths".
