Debunking Hydration/Dehydration - Adam Ruins Everything

harlequinn says...

You had to know what EAMC stands for to understand the abstract. EAMC = Exercise-associated muscle cramps.

This video does not always delineate between levels of hydration. The reality is, you are in general always "dehydrating". This is normal and has no adverse outcomes.

Clinical dehydration (what the video is really talking about) is way beyond the normal ups and downs of fluid loss while maintaining homeostasis.

Khufu said:

Lol, are you telling me science proves humans can't get dehydrated? ugh...

I'm not worried about death from dehydration while working out, but slight dehydration (2%) is enough to dramatically impair cognitive function, performance and recovery. It's just obvious in practice.

Debunking Hydration/Dehydration - Adam Ruins Everything

RedSky says...

No, the meta-study I linked is saying that there is insufficient statistical evidence to suggest dehydration leads to muscle cramps in controlled forward looking studies, contrary to anecdotal backward looking claims which are statistically less rigorous.

This guy does the voice on the video packages and promos for the Six Nations rugby union tournament. Every match feels like a LOTR epic, every player a perfectly balanced coiled spring of pure muscle, sinew and skill.

The Deal with Protein

gorillaman says...

It's weird that this is presented as if it were debunking the idea that you need to eat protein to build muscle, while actually completely confirming that's exactly what you need to do.

US Navy SEALs Combat Swim

chicchorea says...

Wikipedia
"The combat side stroke is a relaxing and very efficient swim stroke that is an updated version of the traditional sidestroke. The CSS is a mix of sidestroke, freestyle and breaststroke. The combat side stroke allows the swimmer to swim more efficiently and reduce the body's profile in the water in order to be less likely to be seen during combat operations if surface swimming is required. The concept of CSS has been that it can be used with or without wearing swim fins (flippers), the only difference being that when wearing swim fins the swimmer's legs will always be kicking in the regular flutter kick motion without the scissor kick. This stroke is one of the strokes that can be used for prospective SEAL candidates in the SEAL physical screening test (PST), which includes a 500-yard swim in 12 minutes 30 seconds to determine if the candidate is suitable to go to the Basic Underwater Demolitions/SEAL school.

Basics

The combat side stroke utilizes the three main fundamentals of swimming:

Balance: There are two things that affect your balance in the water - the head and lungs. Most people when swimming, especially when using breaststroke, will swim with their head up[citation needed] which forces their hips to sink down which is like they are swimming uphill and is a sign of being less comfortable. However, if the body is flat/horizontal or more parallel to the water-line it is far more effective and will allow the swimmer to feel more comfortable in the water.
Length: The taller the person is, the faster the speed through the water. As a result, it is important that the swimmer is fully stretched horizontally in the water, as this will reduce the body's drag through the water and allow a higher speed.
Rotation: In most sports, such as baseball, when the batter swings the baseball bat they will rotate the hips to increase the power of the swing. The same principle is applied to swimming. If the swimmer engages the hips and uses the body's core muscles it will increase power."

You rather nailed it.

SFOGuy said:

Clueless question; this style of swimming because it's really energy efficient? Because it makes less wake and is stealthier? Because it's harder to hit someone swimming like this in the water with gunfire?

Sorry, I'm not sure why they settled on this stroke...He says faster and more efficient---but---any engineers/biomechanics/hydrodynamics folks who tell tell me why?

Newly engineered water superglue

newtboy says...

Perhaps I misunderstood, but I thought it was simply transmitting electricity, not creating it. I was thinking it would work as a sensor where, when it's stretched passed the limit, it will no longer have continuity and could sound an alert.
If I'm wrong and it does MAKE voltage, then yes, synthetic muscles for anything really, not just prosthetics, but androids, underwater machines, etc.

Payback said:

Anything that can create voltage through movement should be able to create movement through voltage, unless it's a chemical process. I'm thinking of synthetic muscles for prosthetics.

The ionic version was awesome, and could make a stretch great sensor.

Britain Leaving the EU - For and Against, Good or Bad?

dannym3141 says...

“What power have you got? Where did you get it from? In whose interests do you exercise it? To whom are you accountable? And how can we get rid of you?” If you cannot get rid of the people who govern you, you do not live in a democratic system.

Tony Benn said that. If the only choice I have is to leave now or never again, then I opt to leave a non- (possibly anti-) democratic system.

I'd stay for the protection it gives us from the Tories, but then I'd be making a lifetime choice based on a 4 year (or less!) problem. I'd stay for "togetherness" but that is just a nice word to describe a bunch of people that intentionally humiliated Greece for the sake of flexing muscle, dooming them to non-recovery for a pound of flesh.

John Oliver: Primaries and Caucuses

bareboards2 says...

@newtboy

What gave the impression that you think Hillary should drop out is because you are calling for a "debate" at the convention EVEN IF she has it locked up. Why would she do that?

IF IF IF IF she has it locked up, I really want Sanders to use the political muscle he has accumulated to help shape the Dem platform. That is what he says he wants to do, and that is what I hope he does.

Get federal minimum wage increase as a plank in the platform (and good grief, tie it to consumer price index so we can stop having to beg for it every 20 years or so.)

This won't happen, but I would LOVE a tiny tax on all investment transactions. I don't need to have it tied to education, but it wouldn't bother me if it was. If we had that tiny tax, it would stop some of the horrendous volatility in the market as this folks chase fractions of a point going up and down. It's stupid what they do with computers and has nothing to do with capitalism and everything to do with chasing a buck in a virtual market (nothing being created except hard-ons -- tax those hard-ons, baby. Tax 'em.)

What other planks would you like to see in the Dem platform? Those are two that come to mind.

Puppyhood

CaptainObvious says...

I liked this video so up voted. I would however avoid buying Purina puppy chow. Terrible, terrible stuff. Choose a food that does not contain Poultry by-products.

https://en.wikipedia.org/wiki/Poultry_by-product_meal

http://www.dogfoodadvisor.com/choosing-dog-food/animal-by-products/

Poultry by-product meal (PBM) is a high-protein commodity used as a major component in some pet foods. It is made from grinding clean, rendered parts of poultry carcasses...Poultry by-product meal quality and composition can change from one batch to another....Chicken by-product costs less than chicken muscle meat and lacks the digestibility of chicken muscle meat.

Bionic limbs are becoming more...human...(surprise reveal!)

rebuilder says...

Huh. How does this work? I mean, this is a pretty elementary question, but it seems it's a pimped-up peg leg - the only actuator is at the ankle, right? So no muscle or motor to bend or extend the knee joint? Which would explain the slightly odd gait - he'd have to throw his foot ahead a bit to get his leg to straighten out.

edit: I'm an idiot. It's a below-the-knee amputation.

Oregon Cop Kicks Biker in Chest

newtboy says...

I especially liked the repeating "clearly did not violate established procedures or tactics" part, but no indication that they understand that all that means is the established procedures and/or tactics need to be changed so they know they can't kick people who have surrendered and complied. It sounds a lot like they didn't learn anything and will be paying out more, and larger settlements in the future until the amount is large enough to wake them up.

I also liked the "Edwards acknowledged in his testimony that Wilkens had begun to comply with his commands when he landed the kick, but said he was unable to stop the kick because he “already had the muscles fired” in his right leg." part, like he still doesn't know there's video of him taking 2 steps forward then kicking all while the motorcyclist is going down to his knees. Just so much fail.

EDIT: Oh, I missed the brake fade part. I notice the hood dip, then rebound as he hits, then quickly lets off the brake, accelerates slightly, and turns right into the bike to ram it. Brake fade might let him roll forward slowly, it would not let the front of the car raise up like the brakes were released and accelerator hit, and would not turn the wheel in the direction of the biker. That wasn't brake fade, no way, it was an intentional ramming. I'm a bit surprised that wasn't brought up in court.

Mordhaus said:

Wilkens was awarded more than $180,000 in total damages.

Jurors additionally determined that Edwards acted with negligence when his police car rear-ended Wilkens’ motorcycle, but ruled that the veteran state trooper did not violate Wilkens’ rights by pointing a gun at him and using force to handcuff and then pull Wilkens to his feet.

Wilkens suffered a broken left clavicle, a fractured rib and other injuries in the Aug. 3, 2012, incident.

Some other nice bits in the article, the officer was driving an unmarked chevy camaro, was unaware that it was equipped with a dash cam, and blamed the rear ending of the bike on 'brake fade' (which a brake expert testified was rare in modern brake systems).

It's a fun read, also the cop was later promoted to captain.

You are once again mistaken....
Real verified stats are had to come by, but: "In the coral reef community there are many species of fish which fill this ecological role: roughly 25 percent of the fishes are herbivores or make plants a part of their diet/omnivores (Deloach, 1999)."
That's just fish, far more abundant than land animals by number or biomass, as a group are at least 75% carnivore (not omnivore).

"obligate carnivore" is not honest, scientific, or reasonable. That means 10% CAN'T eat plants, not that only 10% does. Most animals are neither pure vegetarian or carnivore. I know vegans have a history of ignoring omnivores as a category, because it erases their positions/arguments, but that doesn't mean it's not a major category, in fact it's THE major category.

Herbivores have digestive systems designed to break down cellulose. Humans have one stomach, not designed to break down cellulose, so if it's a choice between carnivore or herbivore, biologically we are carnivores, which makes removing the omnivore category just plain silly for vegans.
