that you can do right now
あなたの脳の向上に
positive benefit for your brain
あなたの気分や集中力を高める
どう思われますか?
could actually last a long time
持続的な効果があり
from different conditions
認知症等の病気から
Alzheimer's disease or dementia.
of physical activity.
パワフルな効果のことです
and protective benefits for your brain.
保護的な影響を与えます
for the rest of your life.
持続することも可能です
is tell you a story
understanding of neuroscience,
the science underlying
なぜ運動が
is the most transformative thing
I know that our brains,
私たちの脳ー
known to humankind.
to talk about the brain,
実物の人間の脳をお見せします
that we are going to talk about today.
二つの重要な部分がわかります
right behind your forehead,
前頭前皮質
focus, attention and your personality.
重要な働きをする部分です
in the temporal lobe, shown right here.
ここ 側頭葉にあります
the right and the left,
左右2つの側頭葉があります
is a key structure
memories for facts and events.
重要な構造があります
is called the hippocampus.
with the hippocampus.
that lasts just a moment,
that has changed your brain,
一生の間続く脳の変化をもたらす
the activity of individual brain cells
those brief bursts of electrical activity,
communicate with each other,
to form a new memory, or did not.
しなかったりするか解明したいと思いました
I did something very unusual in science.
科学の世界では珍しいことをしました
my research program.
that was so amazing,
可能性を秘める
the brain-changing effects of exercise.
その効果を自ら体験したのです
inadvertent way.
of all the memory work that I was doing --
記憶に関する研究は快調に進み
for all of this memory work.
知られる存在になっていました
It was, scientifically.
―科学的にということでしたが
out of my lab door,
頭をつき出して見ると
listening to those brain cells
many years to realize it,
何年もかかりましたが
by myself, because I had no social life.
社交生活がなかったので一人で
I was the weakest person on that trip."
一番体力に欠けていた」と思い
like the weakest person
二度と思いたくない」と
ジムに通うようになりました
classes at the gym.
参加することしました
dance, yoga, step class,
ステップ運動
sweat-inducing workout that I tried,
and this great energy boost.
感じることに気付きました
going back to the gym.
I even lost that 25 pounds.
11kg増えた体重も減りました
into this regular exercise program
made me sit up and take notice.
writing a research grant,
研究費の申請を書いていると
through my mind before.
一度もないことでした
うまくいっている」
always laugh when I say that,
科学者はみんな笑うの—
決してうまくいかないからです
pulling your hair out,
いつも頭を抱えたくなります
million-dollar-winning idea.
アイデアを考えるのは大変です
the grant-writing was going well,
申請が書けたのです
to focus and maintain my attention
what I was studying in my own lab --
that I had included and added to my life
without even knowing it.
自分を実験台にしていたのでは
what I could find about what we knew
of exercise on the brain.
and a growing literature
興味深い 日々発表される研究結果が
that I noticed in myself.
裏付けていることでした
better memory, better attention.
記憶力や集中力の増強
how powerful exercise was.
気付きました
led me to the big decision
きっかけとなり
of really focusing on this question,
集中するようになって数年経ち
the most transformative thing
immediate effects on your brain.
levels of neurotransmitters
ノルアドリナリン等の
and noradrenaline.
right after that workout,
あなたの気分を高めます
1回のワークアウトだけで
to shift and focus attention,
集中する能力が高まり
will last for at least two hours.
示しました
will improve your reaction times
短縮することが明らかになりました
at catching that cup of Starbucks
カウンターから落ちるとき
つかむことできるということです
they help you right after.
運動直後のことで一時的です
私が実践したことです
increase your cardiorespiratory function,
心肺機能を高め
changes the brain's anatomy,
brain area, the hippocampus.
海馬から始めてみましょう
produces brand new brain cells,
実際に作り出します
that actually increase its volume,
実際その容積を増やします
your long-term memory, OK?
いいですね?
in neuroscience studies,
神経科学の研究結果は
dependent or your prefrontal cortex.
注意機能の改善
better focus and attention,
increases as well.
immediate effects of mood with exercise
即効的に気分が改善するだけでなく
in those good mood neurotransmitters.
神経伝達物質の増加が長続きします
that exercise will do
一番大きな変化は
about the brain like a muscle.
and prefrontal cortex gets.
大きく 強くなります
and the hippocampus
susceptible to neurodegenerative diseases
老化現象による通常の認知機能の低下で
over your lifetime,
dementia or Alzheimer's disease,
is you're going to create
and prefrontal cortex
to actually have an effect.
時間を引き延ばします
脳のために高額を払い込んだ
考えてみてください わかりますか?
一切お金がかからないからです
where everybody says,
いつも聞かれることが
want to know one thing.
知りたいのはたったひとつのことだけ
the minimum amount of exercise
the answer to that question.
a triathlete to get these effects.
その効果は得られます
three to four times a week exercise
you don't have to go to the gym
高い入会費を払って
in your power walk.
日課の散歩に一周足して見てください
as the aerobics class
パワフルに掃除すれば
同じぐらいの効果です
workings of the brain,
can improve our brain function,
理解する方向へと進みました
that I just gave you --
週3~4回 最低30分という
the optimum exercise prescription
at your fitness level,
効果を最大にして
and protect your brain the best
したいと考えています
and it's another to do it.
実際にするのとでは違います
as a certified exercise instructor,
インストラクター」の権限を使い
just one minute of exercise.
呼びかけに応える形式です
just do what I do, say what I say,
言うことを繰り返してください
your neighbor, OK?
いいですか?
it's right, left, right, left.
そこで右、左、右、左
力が満ちてきた
I am Wonder Woman-strong.
ワンダーウーマンみたいに強く
アッパーカット 右、左
どうぞ!
right and left, right and left.
引っ張りましょう 右から左、右から左
どうぞ
残したいと思います
exercise in your life
a happier, more protective life today,
導いてくれるだけではなく
from incurable diseases.
備えとなります
the trajectory of your life
あなたが歩む人生の軌跡を

Why you should listen
Dr. Wendy A. Suzuki is a Professor of Neural Science and Psychology in the Center for Neural Science at New York University, an author, storyteller and fitness instructor. She received her undergraduate degree in physiology and human anatomy at the University of California, Berkeley in 1987 studying with Prof. Marion C. Diamond, a leader in the field of brain plasticity. She went on to earn her PhDin Neuroscience from U.C. San Diego in 1993 and completed a post-doctoral fellowship at the National Institutes of Health before accepting her faculty position at New York University in 1998.
Suzuki's major research interest continues to be brain plasticity. She is best known for her extensive work studying areas in the brain critical for our ability to form and retain new long-term memories. More recently, her work has focused on understanding how aerobic exercise can be used to improve learning, memory and higher cognitive abilities in humans. She is passionate about teaching, about exercise (intenSati) and about supporting and mentoring up and coming scientists.
