They almost killed the guy it seems like

[@41mavsrule]

"he could suffer permanent brain and kidney damage" But we`re gonna make him keep running anyway :D

[@makiimedia]

holy fuck what a machine. I ve ran a marathon in quite some heat and drank almost 2 litres in process and still almost fainted. this is ridiculous conditioning

[@Disinfo321]

Running on a treadmill doesn't have much to do with conditioning. The treadmill does most of the work for you, running without a treadmill is a lot harder

[@jailking11]

Hulse EFC Running a treadmill wearing freaking tinfoil suit and those intense lights shining right at him. NO EXCUSES LOL

[@Disinfo321]

a marathon in heat is different to running on a treadmill and dehydrating, its different from cardio really. Boxers and MMA fighters do it all the time before weigh ins

[@KJT922010T]

He is a beast, To do the course two seconds faster when he was dehydrated compared to 35 seconds hydrated is amazing, Rugby is a nonstop sport, He has trained his whole life I'd say.

[@ryanfarewell7927]

+Kevin James Honestly you need to be born with the genes to play as well as dedication and commitment. I can't believe the things these guys do

[@VacaflorVids07av]

Yup you nailed it

[@soundlessbird9181]

How about motorsports, a formula 1 driver dehydrate faster, and they must drive nonstop for atleast 90 minutes.(Modern day 305 kilometers race, winner usually finish in 90~100 minutes, if SC goes out,will be longer.)

[@ddmmh]

@@soundlessbird9181 Get real! You're comparig F1 to Rugby? An F1 driver is lean with low muscle mass, the most conditioning they do is on their neck, light and focused excercise and a strict diet. Totally different animal playing Rugby.

of course he would have a small improvement cause he had done it once before so he was more used to it

But he just lost 14 pounds worth of water...

Not only that he also probably doesn't have as good accuracy in the second one.

lol blistering 35 mph

[@Justintdot]

Thats the part i laughed at to

[@maxstephens4475]

I disagree. Any of us sports players will say that dehydration will have an effect on our game. It didn't really have a large effect on him, but I did notice that in the first course, he caught the ball before walking on the beam. Doing it the second time, he caught it on the beam. Also, they didn't show him hitting the target the second time, so he either missed or didn't have as much accuracy. His lifting of the teammate wasn't as good either. Also, he knew the course better, because he did it once before. Maybe I'm right, maybe I'm wrong, but leave your thoughts below.

[@stonefit]

max stephens I believe that what this proves is how important your mind set is!! He seemed hell bent on beating his scores from the first test. you could see he was more focused when you looked at his eyes. The mind can do amazing things when you let it

[@adacompliance]

+Max Stephens Mentioned the wrong hormone, try ANP for the improvement because he was warmed up. Have had that improved phenomena happen, so long as you aren't going to aerobic exercise, expect improvement

[@socksrocksandocks4824]

i was thinking about everything you just said lolol '

[@socksrocksandocks4824]

i was thinking his muscles had to be warmed up from jogging for an hour

[@SkepticalCaveman]

Instead of only doing the course once each time, he should have done it several times in a row and then they should have taken the average times and compared them.

[@jordaneisenman4894]

[@VotePalpatine]

i play outdoor roller hockey in the summer, when its regularly around 90 degrees and often over 100 if you take into account the heat index. I usually take like 3-4 huge bottles of water to hydrate myself with, its crazy how much having just a few sips of water can re-energize you.

[@j3susj1had]

agreed... so much running in wrestling. this is what its like EVERY SINGLE DAY... then on top of that, 15-20 minutes non-stop live wrestling AFTER AT LEAST an hour of running. wrestling practice is no joke. best conditioned athletes in the world

[@hjarnfysik]

Haile Gebrselassie lost 10% of his body weight when running his 2:04 in Berlin in 2008. Its common and not dangerous because the brain regulate thirst. Its much more dangerous to overdrink. Read Waterlogged by Tim noakes.

[@sethyuri]

Time to try this at the gym

[@taweraster]

@cbinsyd He's one of the best in his position in the World, he leads the 14th ranked team in the World and is constantly outplaying his opposite number, he's had man of the match performances against multiple tier 1 nations and leads his team from the front like all good captains do. He's the greatest player the United States has ever seen.

[@Phanterhunter43]

I researched what dehydration can cause gut (stomach ache/flu) dizziness,feeling weak, fainting and vomiting loss of hearing and slowly lose vision. ive experience stomache flu then come loss of hearing and vision which makes me almost blackout but they said its not that serious u just lack of water.so don't worry.

[@RightfootWestHam]

I have such respect for Rugby players! I knew they were tough, but this tough? Comon, that's just insane! I would have been like a drunk man on that course after an hour in that heat, even without the treadmill nor the suit!

[@JuGGernaut81295]

this rugby player is the captain of the USA national team and now i know thats not saying much but what does say a lot is that hes played for professional clubs in new zealand and south africa

[@Rhinobeast95]

They should of had him do the course in the hot temperature. I play football in Florida in 95+ weather and definitely feel the toll of dehydration.

[@BrockMak]

@SoulOfMasterDragon John ran the same thing for the X-Bionic suit segment. He ran for a tad over 15 minutes before he tried the suit on.

[@meg3ravr]

you are correct

[@Beast0703]

Totally agree

[@nosyrosie3716]

That's probably why, I hated running track because I needed to drink more water. Thank you for sharing.

[@KangenAlec]

Thats why its important for athletes drink Kangen water. The micro-clustering property can hydrate the cells 10 times faster than any other (and often toxic) water

[@hiro_skater9654]

Love how this video is about being dehydrated but my dad had me practice my score like that I had to earn water breaks 4 touches with the soccer field and I had to score on fourth touch Im now used to not having water and got more durable then teammates I wouldn't recommend do it my body need more water and I didn't mean the day where I passed out , throw up felt sick I was doing all this is 90 something wether

[@rextransformation7418]

Question: could it be that's also, y'know... lighter? Meaning, faster?

[@LeoTheLion811000]

You guys are Great!!!

[@houstonlundy5888]

Well for one they have more padding and clothing and the helmets add a greater dehydration of the brain. While football games are not nonstop they do last much longer. And the last point is conditioning, a football players conditioning takes a backseat compared to a rugby players due to stopping starting which allows for ample rest time between plays unlike rugby.

[@getmajor]

not sure if i understand the reply but,I think athletes are more vulnerable only because of the activity increase.Oppose to a regular Joe,But technically the show is based on sports,so i guess that's why the science assumption and study was made. all in all being hydrated is all around a key factor in a healthy lifestyle so i recommend people do keep up with a balanced water intake and good diet. athlete or not.

[@yuktuk8422]

Um the first run he waited to catch the pass before running on the beam, the second time he just kept going and took the pass while on the beam. But the 1 hour of running in between.... bloody amazing. And gotta say, the whole video did not help the point they were trying to make.

[@swainardana6703]

so next time i play soccer, i need to dehydrate myself first

[@socksrocksandocks4824]

lol dont this is verry flawed

Don't it is not cool man. You would probably die. Just don't.

[@Kombaiyashii]

[@richard-kk6ww]

best part of this video was him drinking that shit in slow-mo, lmao

[@Thexxroquexx1]

Damn when I was just running for like 5 minutes (it wasn't that hot either) I became really dehydrated and I almost fainted. I couldn't even run

[@cdfizzy5749]

This video can be summed up to "how to kill a pro rugby player"

[@Persadish]

Thank you, good sir. Max was only trolling. But in doing so, I got to spread a little truth out of it. So it all works out in the end.

[@IndyTheGreat]

I agree with you, but it looks to me like they let him rest (he was dryer when he started the course again than when he finished with the treadmill)

[@medicaldoll5506]

This isn't really conclusive for JUST dehydration. It's more of dehydration and heat. I wonder if dehydration from just not drinking much water or fluids would cause different effect on a different timescale. I know I'm always dehydrated. I only drink like 40 oz of fluids a day. Mostly diet soda. I'd love to see a study on that.

[@Gooseswingman107]

What would be interesting would be to have a top conditioned athlete from all the major sports try this and see who could handle that. Rugby is a very high intensity sport, that's why everybody on the field is in great shape, no room for fatboys in that sport. For football I guess an equivalent would be a TE or LB, soccer would be anyone since they are all around the same build and basketball would be a PF or SG. I'm saying this to take an average sized player from each sport, cancel out the extreme tall or short, light or heavy players.

[@merdleterdlejacob]

MF for soccer, they have to run the most: work as defender and attacker when needed.

[@houstonlundy5888]

This was cool but the only problem I have with the experiment is the number of times he went through the course. The first time he went through the course he was unfamiliar with it (unless he practiced the course beforehand or this is a typical course for rugby players, they didn't mention this so I'm concluding it was his first time) which adds time due to unfamiliarity but he was more familiar the second time which can knock off time. Interesting to know how the body reacts though.

ok whether they fake the chair shots or not theyre still getting hit by it or thrown thru a table or off a ladder which can still hurt either way and espicially when the accidents do happen snap ur ankle like sycho sid and see if thats fake

[@oliverparrish3489]

rugby players are the toughest athletes bar maybe fighters but they didn't have to put him on the treadmill for more than half an hour cuz his his adrenaline would have already been going as well as by the end of the hour and u can play sports in such a way were u try and play using a adrenaline rush because u preform better than before and better than u should

[@drinksbadmed]

running on a treadmil for an hour is gonna effect the results anyway right?

[@kylo445]

Totally different dehydration, than the marathon runners get. Marathon runners, run for hours in heat, or whatever condition which makes up for the 56 minutes he ran in those blazing hot heaters whatever they're called.

Because this based on athletes ,not professional sitters.An athlete is involved in a physical sport.so running on the treadmill is similar to playing basketball or football all the way down to the klutch...sitting in a sauna is nothing like becoming dehydrated during physical sports.

[@andrewwalk1370]

California rugby tour thanks for Shari Eubanks for getting that all organized 3 hours plane 9 days car and your spring dues can be made out to USA rugby. College rugby.

[@LukeJitsu]

Haha a Rugby player isn't the right athlete to use for this. Rugby players are some of the most conditioned athletes in the world. They are used to that. Rugby players play almost as long as soccer players but it evens out because rugby you tackle, you Ruck, you scrum, you play defense the whole time, you never really get a break. So rugby players are badass.

[@goblin183]

please explain?

[@Endero]

@DaDragon47 ur right dude

[@whpainting]

What about running for an hour. Can't that decrease performance?

[@eliegodbout6469]

He beats his time by 2 seconds but he is much more efficient in the second run he has started walking on the beam while he catched the ball and gets out of the tunnel much much faster.

[@colmmccarthy1751]

Is that not really unsafe.

[@zachwillandcarl5157]

Is it dehydration or heat?

[@JoeMeats]

wow the blood thickens and the heart has to beat faster to compensate? Hes running on a treadmill so basically his heart is working like 10 times harder, this guys got some balls

[@ARCKRkings]

that water look refreshing I also lost 40 lbs from the suna suit and sweet sweat freaking hell

[@530Athlete]

As a rugby player i gotta say we play for 80 minutes in all weather hot and cold plus Todd's a pro so he could last even longer than a college or recreational player. Overall this test was unreliable.

[@tylerr75]

i have respect for rugby players they do everything a football player does without pads

[@TheClancy1997]

His muscles where warmer when he did it the second time

[@wowhint]

i dehidraited while being sick ended up in hosp for 2 weeks not good

[@lancedennis5579]

Thats true it brings the factor but when playing a sport you don't just get dehydrated you get tired and it would give this test a more realistic factor.

[@8701F]

I'm a mma fighter.. and what they don't tell you is that he woudn't get far if he did it again.. you have no stamina when you're dehydrated.. So if your form of succes is getting something done in 30 seconds, go for it :)

i love this guy i just wish he wouldn't left the super 14 for club rugby in japan!

Just remember, he’s a rugby player. He’s used to nonstop play under demanding conditions. I doubt that many athletes of other sports could have done this.

[@calebpowell546]

Yea, I don’t like dehydration. I had minor dehydration and vision was blurry, the head ache was terrible and I was nauseous. I couldn’t even walk without having to throw up 😂

[@shaochiavang]

Ive never seen rugby but im sure both sport requires the players to be physically fit. I personally think soocer players has the most stamina.

did they mention if his pass hit the bulls eye?

[@LHRGAMER973]

that water looks so good

[@griffishep1]

So we should dehydrate ourselves before we perform...?

[@clubrome35]

they should have made him run the course a few times then average it for his baseline anyone knows you get better with practice and that first one was his practice. also he seemed to cut some corners in the second attempt

[@fakenews2584]

We have a rugby team

[@purrball16]

just becuz of the last scene I feel like drinking 3 gallons of water now :D

[@RichardsWorld]

He is definitely an elite athlete. Forget about hydration, an average person running on a treadmill for an hour will be slower.

They should try jonah lomu

[@latiremo9133]

Narrator:”He can potentially die :). But we make him continue anyway lol”

[@camq-py7bs]

Lmfaooo this is an EXTREME case. Running in that suit was extreme for an hour.

[@furaka1]

The point is that you can't, with any certainty, suggest that dehydration was the 100% cause of the performance difference. They're other variables that were not controlled for. Todd exercising on a treadmill and then repeating the test would affect the results. Prolonged exercise could cause fatigue, regardless of dehydration. Therefore, they are unreliable - in the world of science and research. I'm a sports science student and watching these has me cringing at some of the stuff they say.
