Youtube daily report Jul 24 2017

What's up Champ! I'm Vince Del Monte of GeneExpressionTraining.com. In this

video we are going to start a brand new series called "The Truth About." And we are

going to explore some of the what may be called some of the more "controversial"

exercises. In today's video we are going to look at the truth about leg

extensions. We are going to uncover a lot of myths. We're going to look at is it

good? Is it bad? Is it better is it worse? What are the pros what are the cons? When

should you do it? When should you do not do it? How do we do it? And we're going to find

out if this is an exercise you want to keep in your program alright. This video is

going to be very eye-opening. Very different than anything you've heard before

so let's get into it.

So before we dive into the leg extension we need to understand

the three different types of force that we can create within our joints. This can all

be found in any biomechanics textbook if you'd like to learn more. Don't ask me is

there a study to support this. This is all basic biomechanics guys so the first

of three are what's called compression. The second is called distraction and the

third is called shear. Alright. So when we're training in the gym, compression is

when we add a barbell to our back and all the joints underneath that load are

being compressed. So when you're doing a back squat, all your spinal muscles are

being compressed. That's compression alright. When we're

doing a pull-up, that's called distraction. That's when your joints are

getting pulled apart and the only thing keeping you together are your ligaments

and your muscles contracting to keep your body together. The third type of

force is called shear. Alright. Shear is when we have two joint

move around each other. Now shear is a term that people hear and they get

freaked out about. Shear is natural. It happens in every single shoulder joint

sorry every single joint in your body. Your shoulders, your hips, your knees, your

ankles. Alright, it's a natural thing alright. So when you hear people talk about oh

don't do the leg extension it creates shear in your knees, every single shoulder

exercise creates more shear in your shoulders than the leg extension creates

shear in your knees. So if you're afraid of "shear" from leg extensions, that even

goes for leg curls too then stop doing all shoulder

exercises today because there's far more risk with those ones than with the stuff

down there alright. So that's the first thing we want to learn about

the leg extension. There's nothing wrong with the leg extension because it's a natural

joint motion alright. So that's take home number one. So now that you know

that shear is not unique to any single joint in the body, it's a natural joint

motion, it's the natural rubbing against joints when two joints are moving in

opposite directions we don't have to be afraid of sitting on a leg extension. Now

let's look at this exercise in context to goals alright. Let's talk about

building muscle alright. We're going to compare two exercises. Leg extension and

squats. You saw this coming right. So barbell squats. We've got load on our back

but when we're standing there with the load on our back is it hard?

Is there any challenge to the stuff at the front of our lip above our leg,

the quads. You got load on your back. Is this hard? No. You could probably stand

here for quite a while. Alright. When does it become hard? It becomes

hard when we start creating what's called torque. We start moving our hips backwards.

We start flexing our knees. Alright. The more your hips go back, the more your

knees start to fold up that's when the weight becomes heavy alright.

So when's a squat hard? It's hard a little bit in the middle so a lot of you

guys could, you know, take 3-4 plates and if I told you to go down a quarter

you could probably hang out there because there's not maximum torque. Now

when we go down to halfway and as they create an isometric contraction here

you're like oh, this is a little harder, when does it become maximally hard? In the bottom

position. Alright. Now if the weight's the heaviest it's in the bottom position and

that's when your muscles are the weakest are you going to get a strong

contraction from your quads? Probably not Alright. It's called the principle of

inappropriately increasing resistance so as your muscles are getting shorter

they're getting weaker but the loads getting heavier. So how can you create a

forceful contraction in your quads when your muscles are weakest and the weights

the heaviest? So you're in the bottom position, the loads

the heaviest, are you hanging out down here? No. You're getting out of that

position as fast as possible. So if our goal is to build muscle tissue, the squat,

while it has benefit, it's not the best quad builder. Try it now. Let's look at

the leg extension. I'm going to sit right over here. So what's cool about the

leg extension machine we can create what's called stability all right we can

now focus on what we want to challenge so if we want to build bigger legs we

want to eliminate ways to make it easier. With a leg extension one of the cool

things we can do is we can create an isometric contraction at every point of

the range of motion. I can create a lot of tension on my quads just with this

partial range of movement a lot more tension than I could create with a

partial range of movement on a barbell squat. If I'm coming up to half way and I

just asked you to hold this and contract this is very very hard. Your muscles are

going to be working because you can't borrow any help from any other joint

systems or any other muscles. So what's going to produce more muscle? Something

that's easier or something that's harder? If your goal is to build muscle we need

to make it hard. If we take this up to 90 degrees and I say hold this for 10

seconds is this hard? This is very hard. You can even see in the demo here I'm

starting to kind of shake a little bit. my muscles are working so one of the big

benefits of the leg extension is that we can isolate this muscle. We can create

massive amount of fatigue without borrowing other muscles. Is that a smart

way to build a muscle? Absolutely. So stop saying barbell squats are better than leg

extensions. While barbell squats are certain a very valuable exercise they

will not create as much fatigue in your quads as the leg extension will and you

can feel it for yourself. When was the last time your legs quivered at the end

of a heavy squat workout. versus a really heavy leg extension

workout. Not the same right. You'll be tired but you're not your quads will

never be the limiting link on a squat workout and if you're trying to take

your quads to exhaustion to build them that's what you have to do. So people

that tell you all you do is compound exercises to build a body

part they got it all wrong. I'm not saying there's not value but if

the context is building muscle tissue, there's a lot of problems as we just

looked at. Now I do want to talk about one problem with the leg extension and

it's how you get to the end range. Alright.

Nobody talks about this. If two cars we're driving on the road and they

bumped into each other like this at maybe five miles per hour, we're going

to have much damage? Probably not. But if we have two cars flying 100 miles per hour

and they crash into each other what happens? People get hurt. So the only

issue I have with leg extension is how you get into the end range all right.

So this is the problem. Lack of control. and end ranges when we're not

considering all the inertial components. Alright. So the problem with leg

extensions is when people use terminal velocity into the end ranges. If you're

moving into the end ranges with control there's no problem at all. It goes back

to our really simple message. Go slower. Control the weight. This stuff isn't

complicated guys. People just want to make it complicated because they're

running out of content to talk about on their channel. We're just trying to keep

this simple guys. This is a no-nonsense Channel. Last thing. There are a few other

considerations with the leg extension. It's never the exercise itself. This is a

hinge joint. This is a natural movement for your knee. The problem is

when we don't set up the exercise properly. So I'll show you the big mistake.

The big mistake is when we don't keep these joints in alignment. The humerus

and the upper leg and the lower leg. Let's just use simple terms. Upper leg or lower

leg. So how do we know if these are lined up properly? Very simple. Our knees are

facing the ceiling aright. So look down at your kneecaps. If your kneecaps

are facing the ceiling, that means you've got neutral alignment of your hips and

you're going to have maximal contraction on your quads once your knees turn out

like this that's when we start getting issues in the knee joint. Again, it's not

what you do, it's how you do it. That's why you've got to avoid people on the

internet who use these like absolute terms

like the worst exercise, the worst exercise ever, the best exercise, because

this is just click bait. Just trying to get your attention all right. We know that

there's nothing wrong with this. This is a natural joint motion. Look this is. This

is not natural. When we've got external rotation at the hips and then we've got

external rotation at the knee now we have unnatural joint forces going

through the knee. You see that. But when this is all lined up

that's all quads. You grab the handles you pull your ass into the seat and you

go to town. Don't crash into the end point.

Don't waste ends. We talked about this in other videos and squeeze the muscle like

it owes you money. If your muscles are moving the joints

are fine guys. The problem is when you start losing control. Simple concept, eh.

So start teaching your friend there's nothing wrong with the leg extension.

Tell them to watch this video. Tell them to line it up properly. Tell

them to initiate the work the movement with the working muscle. Tell

them to own the movement. Tell them to drop the weight. Tell them to control the

ends. If your goal is muscle tissue the leg extension is a fantastic exercise. You

will never get hurt doing a leg extension if you do it with control. The

only challenges occur when you start losing control, joint systems are

crashing into each other. It's a very simple message guys. Are we getting through yet?

Last thing I want to say something I'm very aware of but we don't have time

this will require another video but there's a lot of different kind of leg

extension machines. They all they don't all have the same resistance profile

alright because of the way the cam is set up alright. So that's another topic

for another day let's just leave it at that. Make sure you are aware that these

not all leg extension machines are created the same. I'm fully aware of that.

Again we don't have time to dive into that today. If you'd like me to do that

in an upcoming video let me know and also let me know what other exercises do

you want to look at the pros and cons of is that a friend is it a foe and you're

probably going to find the answer always comes down to it depends on how we do it.

Alright. So we're going to look at the leg press we can look at chest flies we

can look at upright rows. There are certain exercises that have more

issues than others but let's look at it together. I'll be honest I don't have

time to watch everyone's YouTube video alright. I seriously don't okay. I've got

two kids a business I got a family. I like having a life. I don't have time to

watch all the information out there so if you can do me a favor and say Vince

there's a guy on the internet who says this about this exercise what do you

think of that and let's have a conversation in a positive manner like

that, this channels here to help everybody. I'm not here to put anyone

down. I'm learning myself. Let's learn together. Let's do this in a mature way

wouldn't you agree. Alright thanks for watching guys. Last

thing here if you need a resource for learning how to do all your movements

properly MassMechanics.com If you haven't

invested into it do it now. It'll teach you how to execute all your movements.

What Colors Were Dinosaurs? - Duration: 6:01.

This episode is supported by Squarespace

OK, we know a lot about dinosaurs -- like how big they were, what they ate, and even

how quickly they moved.

But there's one question that has plagued paleontologists for decades: What color were

dinosaurs?

It might sound superficial, but trust me, it is not.

Because until we understand their coloration, we'll never be able to fully imagine dinosaurs.

We won't know what they really looked like, of course.

But we also won't be able to study things like camouflage or display behavior.

And we will never know the full extent of just how wrong the Jurassic Park movies are!

Thankfully, in recent years, a more complete picture of dinosaurs has come into focus -- and

it is in technicolor.

When you picture a dinosaur, the colors that come to mind probably vary, depending on how

old you are.

For much of the 20th century, for instance, dinosaurs were always depicted in drab colors:

gray and green and brown.

That's because, back then, most experts thought that dinosaurs behaved like overgrown

lizards, so they probably looked like that too.

Starting in the 1970s, dinos started to be portrayed as having things like spots, stripes,

and flashy colors.

But not a lot of that was actually based on science.

Then came a major breakthrough from an unexpected place.

It wasn't a dinosaur, but a fossil squid.

In 2006, while a graduate student at Yale, paleontologist Jakob Vinther was studying

a fossil squid with preserved ink sacs.

Those are the little organs where squids store their defensive inks.

And when Vinther studied them under a microscope, he saw that the sacs were filled with tiny

spheres.

Other paleontologists had seen these little blobs before, but they thought they were just

fossilized bacteria.

But to Vinther's eye, they looked like special structures that help give animals color -- melanosomes.

If you've heard of these things before, it's because … YOU HAVE THEM!

Lots of animals do!

Melanosomes are responsible for all of your body's coloration, from your skin to your

eyes to your hair.

Each melanosome contains some type of melanin which is a natural pigment.

And based on their density and distribution, they can create different colors!

Now, I know what you're wondering: What in the name of Charles R. Knight does a Jurassic

squid have to do with dinosaurs?

Well, you know what else has melanosomes?

Feathers.

Experts can look at the feather of a living bird, like a cardinal or a crow, and see what

kinds of melanosomes make that feather's color.

For example, long, skinny melanosomes make black and gray, like the black you find around

cardinals' eyes.

But if melanosomes are short and round, they make reddish colors, like what you see on

red tail hawks.

This information can then be used as a template for studying ancient animals.

So living dinosaurs are basically the color key to extinct dinosaurs!

In 2010, this idea was put to the test in a place that's famous for its abundant fossils

of feathered dinosaurs: China.

There, a team of Chinese and British scientists studied what might be one of the most adorable

dinosaurs ever -- the chicken-sized Sinosauropteryx.

Sinosauropteryx was the first non-avian dinosaur to be discovered with structures of feather-like

fluff, back in 1996.

And after studying the melanosomes found in that fuzz, researchers determined that Sinosauropteryx

was ... ginger!

Its downy coat was apparently reddish brown over most of its body.

But, its tail was a little different - alternating between light and dark bands, giving it some

extra flair.

Vinther and his colleagues used this same technique to reconstruct the plumage of another

feathery, pigeon-sized dinosaur called Anchiornis

And it turned out, this dinosaur looked kind of like a … punk rock magpie?

… mostly black and white on its wings and legs, with a splash of red on its top.

After this, the colors of more dinosaurs were soon revealed.

The four-winged Microraptor?

It had dark, iridescent plumage, kinda like a raven.

And one specimen of the little horned dinosaur Psittacosaurus was even found to have melanosomes

in its skin, revealing that the dino was dark on top and light underneath.

Pretty cool, right?

As long as a dinosaur is preserved with feathers, or some other structure that keeps melanosomes

intact, scientists can figure out their basic colors!

Now, this is all awesome and exciting.

But these discoveries are about a lot more than just what dinosaurs looked like.

They can also tell us about how they lived.

For example, in birds, we know that feathers aren't just used for flight -- they're

also an important part of display behavior.

So, little Sinosauropteryx probably didn't have a banded tail just by chance.

Its flashy pattern tells us that this dinosaur may have had something to say to other members

of its species, like that he wanted to claim his territory, or show off how fit he was

for the ladies.

And the pattern found on Psittacosaurus -- dark-on-top and light below -- is a common phenomenon

seen in lots of modern animals.

It's called countershading, and it would have helped this little herbivore blend in

while walking through the sun-dappled forest.

Thanks to these developments, experts are beginning to uncover the colors of many other

feathered dinosaurs, and new types are being found all the time!

So now we can start answering that question that's been bugging us for so long.

And memo to Hollywood!

If you're planning on having a Sinosauropteryx in Jurassic World 2, now you know what color

it was!

The Scar You Never Knew | #SpinaBifida - Duration: 3:52.

Hey everyone, welcome to #SpinaBifida.

So this is the only angle where I can get the light

to be on me while being by my sink.

But I just got home, I spend the weekends at my boyfriend's house.

And then Monday's I come back

and sometimes I have #SpinaBifida already filmed

and then days like this I don't.

But I need to wash my face so I can head to Starbucks

and edit and get this video up for you.

So I thought today I'd do a little story time video

about a scar you never knew about.

That scar is, the scar on my leg.

(loud buzzing sound)

They're doing construction.

Uh, I just wet my face.

I'm going to use this Simple...

it's just called Simple foaming

foaming cleanser.

That's what I use right now to wash my face in the morning.

When I was around 4, my mom took my 2 sisters

to go to church and for some reason

she left me behind.

I'm pretty sure it's because she knew I couldn't be saved.

She left me behind with my dad to watch me.

And one of my, um, older sisters

from my dad's previous marriage was visiting.

They were chatting I guess

and my dad had told me, you know, don't go in

the garage and I was like

(kid voice) I'll do what I want!

(normal voice) Because I was a kid.

And I went into the garage.

At that time my dad worked at NCR.

Which was like an older electronic company.

AT&T bought them out.

And my dad had a bunch of electronics in the garage.

And they were in these like mail carriers.

Long story short, a piece of metal was sticking out

And (chuckles) it sliced my leg.

So what makes this story funny is that

when my dad found me they wrapped me in a white towel.

I remember being in the car

my sister was holding me in a white towel.

And my dad instead of driving to the hospital

while I'm bleeding,

my dad drove to church.

And this was the day that my mom decided

she wanted to sit at like the front of the church.

My mom recalls one of the pew people

coming down and being like "Ines, you husband is outside

your daughter got hurt."

And it was in the middle of mass.

So my mom had to get up with my other two sisters

to go take me to my hospital with my dad because

my dad just couldn't function at that point.

And I don't remember any of this but I remember

getting stitched.

It's a funny story because the scar is

pretty cool, it's like this half crescent moon thing.

And it's interesting seeing the scar

The technology was new on scars that dissolved.

Because I still had a few back surgeries

by the time I was four.

And those stitches dissolved with butadiene

and then half peroxide half water.

But the stitches they used for my leg

my mom said were the ones that

you had to clean and then go in and they had to

remove the stitches.

That scar, it's harder to tell because I'm older

but it has little dots around the scar.

So you can see where like they stitched.

And it's honestly my favorite scar I have.

That scar even led to this like weird rumor

in high school that my leg was fake.

And I don't know how like

anyone believed it but people really did.

Especially because of my limp.

And it got me in the high school year book.

For like my senior year of "what was the worst

rumor spread about you?"

And so I put that.

But it was like the weirdest thing.

So that's my story of my scar on my leg.

It's not necessarily to do with Spina Bifida

but it's a scar.

And I wanted to share it.

But that's all I have for you for today on #SpinaBifida.

Do you have any cool scar stories?

Does it have to do with your Spina Bifida scar

or do you have like an extra scar?

Share them down below, it'll be cool to read it.

And thank you for watching, make sure you're subscribed.

Lime Disease: How a Fruity Drink Can Give You a Rash - Duration: 4:16.

[♪♩INTRO]

Picture this: you're on a beach, relaxing, sipping on a beer.

You squeeze a lime into your drink and get hit by some citrusy mist while you're sunbathing.

No big deal, right?

Well, actually, because of some chemicals in that lime and UV radiation from the sun,

your skin is about to get attacked.

The symptoms come a day or two after exposure: an itchy, burning rash with fluid-filled blisters

— kind of like a bad sunburn.

It's been called lime disease — that's "lime" with an "i".

You might also hear it called Mexican beer dermatitis, margarita dermatitis, or Club

Med dermatitis, after the tourism company because sometimes people come back with post-vacation

rashes.

The medical name for this condition is phytophotodermatitis, which tells us that it's skin damage related

to plants and light.

Specifically, high-energy ultraviolet light, like the UV rays in sunlight.

This bad skin reaction is caused by certain furanocoumarins, a group of compounds that

some plants use to defend themselves and deter hungry herbivores.

They're in some common plants like celery, parsley, parsnip, and some citrus fruits like

lemons and limes.

Furanocoumarins aren't toxic cell-damaging chemicals on their own.

They're activated when they're exposed to sunlight after a plant's cells are broken

open.

With the energy from the UV radiation in sunlight, furanocoumarins can undergo a chemical reaction

and bind to certain bits of DNA inside another creature's cells, messing with the DNA's

structure.

When this DNA damage happens, cells can stop working properly and sometimes get killed

off.

This reaction is designed to stop animals and insects from eating the plant, since a

toxic substance doesn't lend itself to a great "mouth feel."

Some animals learn to avoid these toxic plants, but certain creatures have evolved ways to

get at their tasty nutrients.

Some caterpillar species, for instance, get around this defense by changing their behavior.

They roll up their leaf of choice and munch on the inside.

That way, they keep their furanocoumarin-riddled food in the dark, so UV light doesn't activate

these toxic compounds.

Other caterpillar and butterfly species make specialized proteins in their bodies that

react with the compounds and detoxify them, so they can't react with DNA and cause damage

anymore.

As humans, our opposable thumbs and culinary arts have helped us get around a lot of plant

defense systems, but furanocoumarins can still affect us if we're not careful.

Limes, for instance, have a cocktail of three furanocoumarins that are concentrated in the

juice and peel, ready to be released and activated whenever the fruit is bitten — or squeezed

into your favorite drink on a beach day.

Furanocoumarins are also found in bergamot oranges, which are a part of the iconic Earl

Grey tea smell, and were a popular ingredient in perfumes.

Before perfumiers figured out how to make artificial scents to replace bergamot oil,

people who wore bergamot perfume outside found themselves with blistery rashes, just like

modern-day Club Med partiers

And that's just because if any of these compounds get on your skin while you're

sunbathing, the UV light will cause that DNA-damaging chemical reaction in your skin cells.

Hello, phytophotodermatitis.

The reason this skin condition basically looks like a really bad blistery sunburn is because

it's a similar kind of damage.

In a sunburn, certain kinds of UV light also damage your DNA, and your immune system starts

killing off malfunctioning cells so they don't become cancerous.

If you do find yourself with this rash, it's usually treated with drugs like corticosteroids

that mimic a hormone and interact with your immune system to reduce inflammation.

Symptoms usually get better after a couple of weeks.

All it should take to prevent it, though, is to wash off the offending lime juice or

other substance right away.

And if you do find yourself on the beach covered in lime juice and can't get to a shower

— hey, I'm not judging — just maybe stay out of the sun like the citrus-scented

vampire you are.

But the Internet isn't a doctor, so, y'know, please actually go see one if you have any

mysterious rashes.

Thanks for watching this episode of SciShow!
