To understand the injustice that has been done to exercise, let’s pretend we’re

back in 1995 and Nintendo is advertising the Nintendo 64.

情態副詞

When marketing, they talk solely about the technical aspects of the machine and how it

has a 93.7 megahertz processor compared to the Super Nintendo’s measly 3.56 megahertz

The N64 flops and the entire marketing team is fired since they failed to promote any

relevant information like the actual nature of the new games or even that an entire D

was added, making the games 3D instead of 2D.

Of course in reality, the Nintendo 64 did quite well.

This hypothetical marketing strategy is just a parallel to the poor marketing strategy

The sales points of exercise up until now were that it’s good for the heart and it

First off, while these are good benefits, they’re not nearly as compelling as the

“Good for the heart” is a vague notion that’s encouraging only if you happen to

be older and worried about a heart attack.

Then, data is showing that exercise isn’t even that effective for losing weight.

A review of exercise intervention studies published in 2001 by Queen’s University

in Canada found that after 20 weeks, "the amount of exercise energy expenditure had

I’m not saying that exercise doesn’t affect your body.

The right kind of exercise increases muscle mass and improves your insulin sensitivity,

setting you up to have a healthier body composition.

However, if you begin exercising without managing other factors like diet, you may be very discouraged

So, here are studies of exercise - as you can see when compared with no treatment, exercise

resulted in very small weight loss across the board.

Muscle have mitochondria, mitochondria burn energy.

So, exercise is the single best thing you can do for yourself, but if you think it’s

gonna show up on the scale, think again.”

In a September 2016 issue of TIME magazine, Dr. Mark Tarnopolsky said that “If there

were a drug that could do for human health everything that exercise can, it would likely

be the most valuable pharmaceutical ever developed.”

To understand what makes exercise so great, we need to understand how it affects the brain.

To create art and to come up with creative solutions to complex problems!” but Neuroscientist

Daniel Wolpert argues that is not the case.

“ We have a brain for one reason and one reason only and that’s to produce adaptable

There is no other reason to have a brain.”

To illustrate this, Daniel uses the example of a sea squirt.

Early in its life, the sea squirt has a nervous system.

It will use this nervous system to move around and find a suitable rock to attach itself

to, then it will spend the rest of its life there.

At that point, movement is no longer a necessity for survival, so the very first thing the

sea squirt does is it digests its brain for energy.

The Koala has adapted its digestive system to derive all the energy it needs from eucalyptus

It really doesn’t need to move that much as it can just sit in the tree, eat, and watch

Earlier in the Koala’s evolution, it used to have a much bigger brain.

However, once its diet became less diverse and required less movement to survive, its

Less movement meant less brain was necessary.

From an evolutionary perspective, it’s the same as not wasting your money on a 4000 dollar

laptop if all you need to do is run some simple software like your web browser and email client.

What research on exercise is suggesting, and a better understanding of neurochemical mechanisms

is proving, is that there is a very powerful connection between the brain and movement.

A big brain is necessary to facilitate complex movements, and executing such movements and

getting your heart rate up bolsters your brain power.

Exercise has been shown to help people learn much more efficiently, better deal with stress,

It improves mood to the point of lifting people people out of depression, and it strengthens

focus to the point that some ADHD patients elect to throw out their prescriptions.

The California Department of Education has consistently shown that students with higher

Former President Ma of Taiwan increased the occurrence of Physical Education in schools

nationwide from twice a week to three times a week for this reason.

The minister of education, science and technology in South Korea extended the school day by

1 hour to add more time for PE and sports.

This decision was made after reading Dr. John Ratey’s book “SPARK” which is all about

The reason the Taiwanese and South Korean school systems don’t just have students

study for another hour is because exercise actually primes the brain to learn faster.

A 2007 study showed that subjects who did high intensity exercise beforehand could learn

vocabulary words 20% faster than those who remained sedentary.

The key to this phenomenon is a protein called Brain Derived Neurotrophic Factor, or BDNF

In order to learn something, the brain actually needs to grow and modify its cellular infrastructure

Researchers found that “if they sprinkled BDNF onto neurons in a petri dish, the cells

automatically sprouted new branches, producing the same structural growth required for learning.”

This impressive result had John Ratey nickname BDNF the “Miracle-Gro for the brain.”

“BDNF improves the function of neurons, encourages their growth, and strengthens and

protects them against the natural process of cell death.

...BDNF is a crucial biological link between thought, emotions and movement.”

A 2013 study in the journal of sports science and medicine showed that just 20 to 40 minutes

of aerobic exercise increased BDNF in the blood by 32%.

Rather than stocking up on coffee before you sit down to study, you might want to try jogging

One way to understand why exercise would trigger your brain to initiate “learning mode”

like this is to think of your body as the world’s most intricate “IF THEN” system.
