쉐도잉 연습: The Shoe That Broke Running - 영상으로 영어 말하기 배우기

I'm wearing the real Team USA Olympic uniforms with one of the world's fastest super shoes.

And we're gonna cut it in half.

Because what's inside this shoe is part of a huge debate happening in sports right now.

The question is, when does sports gear get so good that it's actually cheating?

There's a ton of cool gear that's banned from sports for making athletes too good.

Like swimsuits that make a swimmer's body too streamlined.

Or gloves that make a receiver's hands too grippy or bats that let a player hit the ball too hard, or shoes that make a runner too freaking fast.

They call it tech doping, using physical gear to gain an unfair advantage.

In this video, I'm going to show you the banned technology that you won't see in the Olympics.

Oh, whoa, that's grippy.

And the cutting-edge tech that you will see that's on the very edge of what's allowed.

You might be thinking, hold on, no gear should give athletes an advantage.

But we don't run barefoot anymore.

We don't swim naked.

We use tech to play sports, and that tech keeps getting better, pushing forward what humans can do.

So where's the line?

That's what I really want to figure out.

This debate is about way more than sports.

In every part of our lives, technology pushes humans forward, and it's up to us to decide what do we want from it.

This video is about that question.

Let me show you the cutting edge of sports technology.

I am wearing the fastest suit in the world, and that's a fact.

The fastest suits in the world.

Technological doping.

It is cheating.

A weekend that changed distance running forever.

Nike's controversial Vaporfly shoe.

Fueling new controversy over the suits the swimmers are wearing.

Surpassing human capabilities.

Today I'm at Nike's test lab in Oregon to show you some of the world's best and most controversial sports equipment.

But first, if you were trying to decide whether to ban something from sports, How would you do it?

Here's where to start.

First, most regulators ask, is it dangerous?

To athletes or fans or both?

This is the big reason they give for banning steroids, but it applies to hardware too.

For example, in Major League Baseball, they're not allowed to use aluminum bats.

They have to use wooden ones.

Because aluminum would allow them to hit the ball so fast, they might kill people on the field or hurt people in the stands.

So if gear greatly increases the risk of injury, it might not be allowed.

But most of the cool tech that we're talking about doesn't increase danger.

It just makes athletes better.

So the next question they ask is, is it against the spirit of the sport?

But how do you define that exactly?

Spirit of the sport, it's intentionally vague.

So it gets broken up into smaller questions, like, can everyone use this tech?

Is it fair to record holders?

Does it artificially enhance a player's performance?

Let me give you some examples.

Try to decide what you think is right before I tell you what the rule makers chose.

This is the Olympics in 1972.

Do you notice anything missing?

Nobody's wearing goggles.

Four years later, the Olympics allowed them.

You see early adopters start to use them, and those athletes start winning.

Here's a chart showing swimming records by year.

That's when goggles were allowed.

Most people today would say allowing goggles was a good idea.

But then, something new caused another big spike.

In 2008, Speedo collaborated with NASA to make this, the Laser Racer.

This suit was so cool.

The fabric mimicked shark skin with these little channels that let water flow more easily.

It had these panels that sucked swimmers' bodies into a more streamlined position.

And people speculated that the way it trapped air made swimmers float more easily, which Speedo denied.

But it was clear this new tech was helping swimmers crush world records.

Athletes were doing things nobody thought was possible.

It was awesome.

You remember that Olympics when Michael Phelps won more gold medals than any human had ever won in a single Olympics ever?

he was wearing a laser racer.

Is that fair?

This new suit made the swimming world lose their minds.

The general manager of the US team said the records shouldn't count.

So, should this fancy super swimsuit be allowed?

Within a year, the swimming governing body voted to ban them.

The swimmers you see at the Olympics now are wearing suits made with only textile fabrics

that can only cover this much of their body.

I feel mixed about that.

We can't see well underwater, and our skin isn't textured like sharks, but goggles are allowed and these swimsuits aren't.

But on the other hand, we don't allow flippers.

There's a line somewhere.

It's just not always obvious.

Like prescription lenses in Olympic shooting.

Okay or not okay?

If you said okay, the regulators agree with you.

Olympic shooters are allowed to wear prescription lenses.

They can correct their vision.

They just can't enhance it.

Or how about this, sticky glue that makes it easier to catch a football.

Okay or not okay?

The NFL said not okay, but grippy gloves are fine.

Oh my goodness!

I love these questions because they get at what we think the whole point is of both sports and technology.

And of course, it's so messy.

But the messiest of all is the debate about running shoes and a record that was supposed to be impossible to beat.

He has done it!

Welcome to Nike's test lab.

I'm at Nike to answer a question I've been wondering for years.

Let me explain.

In 2019, I watched Eliud Kipchoge become the first person ever to run a marathon in under two hours.

That is 4 minutes and 35 seconds per mile for 26.2 miles.

100

Here's what that speed looks like for most people.

101

This was supposed to be impossible.

102

But he did it.

103

And while the world celebrated Kipchoge's record, in professional running, all eyes turned to these.

104

He was wearing special prototype shoes, built to make him run faster.

105

In fact, studies showed that this design helped runners at the time go 2-3% faster than the next fastest shoe.

106

And regulators started saying that this shoe threatened the integrity of the sport.

107

But why this shoe?

108

If you look back at the history of running shoes, you'll see that over the last hundred years, they've gotten a lot better than 2-3%.

109

Early running shoes looked like this.

110

They're basically loafers with spikes.

111

People can run a lot faster in basically any running shoe today.

112

So why was this shoe all of a sudden so controversial?

113

Let me show you the answer.

114

This is the newest version of that same shoe design, and I'm about to cut it open.

115

So this is the successor of what Eliyuk Hachoggi beat the two-hour marathon in.

116

Yeah.

117

Awesome.

118

all kinds of technological development.

119

It's a thing of beauty and we're going to destroy it.

120

There's no chance I can put it through, is there?

121

You could guide me.

122

If I lose a finger, it's my fault.

123

Uh, Lindsey, what do you think?

124

Well, we do have her on camera saying it will be her fault.

125

If I cut my finger off, I'm saying it to camera, it's not Nike's fault.

126

Sweet Jesus.

127

No, this is fine.

128

Come on, it's fine.

129

It'll be fine.

130

It'll be fine.

131

It's gonna be great.

132

You got it?

133

Woo!

134

Look at this!

135

Lots of companies now make their own version of a super shoe.

136

And people say they've changed running sports forever.

137

But how, exactly?

138

At a high level, every super shoe today has three key sections.

139

The upper, which holds your foot the outsole, which hits the ground, and the midsole, which mostly determines how much of the energy

140

that a runner exerts down into the ground is returned to boost them into their next stride.

141

This is called energy return, and it's a huge deal in running.

142

Nike's new super shoe specifically maximized energy return by building in a way taller stack of new, cushy foam and a carbon fiber plate that acts like a lever,

143

springing the runner forward, which outside the shoe looks like this right here.

144

They even included special air pockets for extra bounce.

145

Before super shoes, a good energy return rate was about 60 to 65 percent.

146

Now, it's more like 80 percent way more of the runner's energy that they get to reuse.

147

I wanted to show you what that energy return feels like.

148

But to do it, Nike didn't just give me their shoes.

149

They let me try the real Team USA Olympic uniforms.

150

So I'm wearing this, and this, and this, and most importantly, these.

151

Okay, now go away.

152

I feel awesome.

153

Let's do this.

154

They didn't just test the shoe, they tested me.

155

They analyzed my running style.

156

They showed me how these uniforms deal with sweat.

157

And hardest of all, they made me run in 95 degree heat at 70% humidity.

158

Some of your cameras might not work super well in here because they might fog up.

159

What speed would you like to run at today?

160

I'd like to go fast enough to give you some real information.

161

I'll just be right outside the window.

162

So I'll look at you.

163

Thumbs up means I can go a little bit faster.

164

Thumbs down means a little bit slower.

165

Okay, put me in, coach.

166

Yeah, I did not fully understand what I was in for.

167

I don't know how to do that.

168

So I have to go as fast as you'll ever go.

169

I could feel the energy return.

170

It feels like a trampoline on my feet.

171

When super shoes were introduced, just like the swimmers with the laser racer, runners began to crush world records.

172

Marathon times saw the biggest increase in 50 years.

173

People started complaining that the shoes were giving runners energy, but that's not how energy return works.

174

All the energy has to come from the runner, and anyone who runs knows it's not easy.

175

I'm reaching a point where I can't talk casually anymore.

176

She's getting hot.

177

She's been running for two and a half minutes.

178

World's best marathoners can run in this temperature at faster speeds than this for two plus hours.

179

If you're up for it, we'll have you go for about six more minutes.

180

Okay!

181

How you feeling?

182

So fun, right?

183

That's great.

184

You got good sweat going all over the place.

185

Beating up over here.

186

Drifting.

187

Look at this.

188

So, running shoes that make you faster.

189

Okay or not okay?

190

Regulators decided something in the middle.

191

They tried to restrict how much energy return super shoes could give.

192

by implementing a 40-millimeter foam height limit and saying shoes can't have more than one carbon fiber plate.

193

Kipchoge's shoes barely fit these requirements, but they were prototypes, which felt unfair.

194

So regulators added a rule saying

195

that all shoes had to be available for anyone to buy at least four months before they were used in competition.

196

These rules were pretty much aimed at Nike.

197

And back then, Nike wasn't happy about it.

198

They issued a statement saying the rules would stifle innovation.

199

So I asked the head of Nike's sport research lab about it now.

200

Why did Nike feel that way at the time and do you still feel that way now?

201

There was a number of reasons we were pushing back and worrying about stifling innovation.

202

I think it's like just a moral obligation to keep pushing forward.

203

Our goal is not to make the world's fastest athletes faster by putting fans behind them and pushing them down the field.

204

It's not interesting to us.

205

That's really the key.

206

It's all about pushing the human body forward.

207

But that brings us to the last big debate about technology in sports.

208

What if the tech that you're debating is part of someone's body?

209

You might remember this guy, Oscar Pistorius.

210

He was the first person to qualify and compete in the Olympics with these, running blades.

211

This was a moment that got a lot of people talking about what's fair and what's not in sports.

212

You might not know him yet, but that's Blake Lieber.

213

He qualified for the Olympics eight years after Pistorius, but he wasn't allowed to compete.

214

I had, what, the fifth fastest time in the world against able-bodied athletes, which qualified me for the Olympic Games.

215

I was abruptly stopped.

216

I had to take my case to the Court of Arbitration of Sport.

217

The Olympics had allowed Pistorius, but they now wanted to revisit the rules.

218

Should running blades be allowed?

219

If you let people wear glasses for shooting, meaning they can correct a disability that they have, aren't prosthetics the same?

220

And how do you decide what's a correction and what's an enhancement?

221

Turns out, tests.

222

A lot of tests.

223

But dots on my blades to see the spring compression, to see what type of energy return are we getting out of the prosthetic legs

224

and how does that compare to somebody who have their legs?" Researchers found

225

that Blake's prosthetic legs made him no faster at sprinting or gave him better endurance, but they did make him worse at accelerating and rounding curves.

226

Then the opponent's side argued that prosthetics are lighter and they don't require any of the body's oxygen.

227

It was seeming like a toss-up.

228

But then… But the one thing that they got me on specifically was called the MASH rule, max allowable standing height.

229

use this rule for Pistorius.

230

But now, they decided Blake couldn't compete because his blades made him taller than he would be naturally.

231

But Blake was born without the bottom part of his legs.

232

He has never had a full height naturally with his legs.

233

They calculated it using measurements from other parts of his body to tell him what his height would theoretically have been.

234

And to make matters worse, those calculations were based on only small studies of white and Asian men.

235

But the whole idea of using averages for athletes is tricky.

236

Most people's wingspan is roughly their height, but Michael Phelps' wingspan is three whole inches taller than he is.

237

That's part of what makes him so great.

238

But in the end...

239

This is the rules that said, we're sorry Blake, but you have to drop your legs by six inches.

240

And changing your height is not the same as changing your swimsuit.

241

I trained at 6'2 my whole life.

242

Now I'm 5'9", so I'll go reach or I'll go run or my back went out.

243

And the question, the million dollar question is what's fair and what's not fair?

244

If somebody was born with bad vision and they wear glasses, you wouldn't regulate that.

245

I could try to wear glasses, but I don't need glasses.

246

Really the conversation that we're talking about is a fear or a concern that technology will get so good,

247

people on blades will actually outperform everybody.

248

Is that what people are really talking about?

249

I think, yeah, I mean, I think that's the conversation that is really at hand.

250

It wasn't me trying to compete, it was the idea of the Pandora's box that it could potentially open up.

251

I don't agree with it, but I understand.

252

We have come so far in improving what humans can do.

253

Today we have better nutrition and training and strategy and recovery and, of course, technology.

254

The whole point of technology is to make people better.

255

To make our lives easier, to make us more capable, to make things that we never thought were possible come true.

256

But how far and how fast

257

and exactly in what direction technology pushes us is the big debate that we're going to keep on having.

258

Far beyond sports.

259

Should we regulate it?

260

Should we tame it down?

261

Should we allow it?

262

Should we integrate it?

263

I think it's wrong to stop.

264

I think it's, you can say it's unethical to introduce these things to sport.

265

It's unethical to stop inventing and to stop pushing human potential forward.

266

And personally, I can't wait to see what humans are capable of.

267

Welcome to Nike's test lab.

268

That's going to be the ending.

이 비디오로 배울 수 있는 것

이 비디오는 스포츠 기술에 관한 논쟁을 다루면서, 영어 회화 연습에 필수적인 다양한 실용적인 기술을 제공합니다. 첫째, 복잡한 주제(예: "tech doping")를 명확하게 설명하는 방법을 배울 수 있습니다. 둘째, 의견을 제시하고 논쟁을 펼치는 과정에서 사용되는 연결어(예: "but", "so", "however")의 활용법을 익힐 수 있습니다. 셋째, 구체적인 예시(예: 스피드오의 LZR 레이서 수영복, 나이키의 슈퍼 신발)를 통해 주제를 풀어가는 기술을 연습할 수 있습니다. 이는 IELTS 스피킹과 같은 시험에서도 매우 유용한 기술입니다.

들어야 할 소리: 연결된 발음과 축약형

영어 발음에서 자연스러운 연결과 축약은 매우 중요합니다. 이 비디오에서 자주 등장하는 예를 살펴보세요. "what's inside"는 /wɑts ɪnˈsaɪd/가 아니라 /wɑts ɪnˈsaɪd/로 연결되어 발음됩니다. "it's a fact"는 /ɪts ə fækt/가 아니라 /ɪts ə fækt/로 축약됩니다. 또한 "they're not allowed"는 /ðeər nɑt əˈlaʊd/가 아니라 /ðeər nɑt əˈlaʊd/로 발음됩니다. 이러한 연결과 축약을 잘 듣고 따라하면 영어 발음 교정에 큰 도움이 됩니다.

원어민처럼 말하기: 리듬과 강세

영어의 리듬과 강세는 의미 전달에 큰 영향을 미칩니다. 이 비디오의 화자는 주요 정보를 강조하기 위해 강세를 사용합니다. 예를 들어 "the question is, when does sports gear get so good that it's actually CHEATING?"에서 "CHEATING"에 강세를 두어 중요성을 강조합니다. 또한 "we don't run barefoot anymore. We don't swim naked."와 같은 문장에서는 짧은 단어를 빠르게 발음하고, 긴 단어를 느리게 발음하여 리듬을 만들어냅니다. 영어 쉐도잉을 할 때는 이러한 리듬과 강세를 따라하는 것이 중요합니다. 쉐도잉 사이트를 이용하여 반복 연습하면 자연스러운 발음과 리듬을 익힐 수 있습니다.

이 영상의 문법

화자가 가장 많이 쓰는 문형을 영상 속 실제 표현과 함께 정리했습니다.

문형	영상 속 표현
수동태 be + 과거분사 — 누가 하는지보다 무슨 일이 일어나는지에 초점	might not be allowed · were allowed · be allowed
현재완료 have/has + 과거분사 — 과거의 일이 지금도 관련이 있을 때	has done · they've gotten · they've changed

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
