He spends a lot of time on different areas where people can benefit such as addition, pregnancy, disease prevention and especially how it can replace many of the antidepressants such as Prozac. The book is technical in many places but most enjoyable.

I suspect some bias on the part of the author when choosing which studies to cite (informally) in the book, but as a student of medicine I can, to a reasonable degree, certify that the science is all sound. Also, the logical and pragmatic layman would, I'm quite sure, agree with the content of the book; it doesn't request or require any leaps of faith by the reader in order for her to fully engage and sympathise with the overall notion that exercise is positive for the brain in the numerous ways proposed.(less)

Exercise is the single most powerful tool available to optimize brain function. That is the message from this book. Everybody knows that exercise creates a fit body, but what many forget is that the brain is part of the body too. Modern science has been able to learn much about how the brain works, and has even tracked neurogenesis (i.e. new cell growth) in the brain in response to exercise. The old saying, "Once your brain cells die, they can’t grow back," is a myth.

The author attempts to explain for the layman, but ends up using masses of neurological jargon and acronyms, about the role exercise plays in sharpening our mental processes. Boiling it down to the basics: moving our muscles produces proteins that play roles in neurogenesis and the repair of synapses. It also helps the production of hormones such as serotonin and norepinephrine that regulate mood. Therefore, Ratey argues, daily sustained aerobic exercise is a sure cure-all for depression, ADHD, ...more

This book gets a bit repetitive after awhile (I quit after reading about 3/4 of it), and the conclusions he drew from some of the research studies seemed to really be stretching what you could reasonably conclude from the actual results.

But it did convince me that I had to start exercising after being pretty sedentary for the last 4 or 5 years. And six months later, I'm still convinced and still I guess it had a bigger positive impact on my life than most things I read.

If you're the kind of person who needs to be intellectually convinced by mountains of research to confirm something you already know - as I am - and you're trying desperately to start a regular exercise habit - as I am - you need to run and get this book, like, yesterday. I'm actually very serious: I have a very athletic husband, who is the epitome of healthy living, as an example in front of me every day; I've read tons of articles about the benefits of exercise, and have known for practically ...more
Now, it is a universal fact that exercise is good for you. It’s been said and done so what’s so different about this book? Well, 'Spark' dives deeper and attempts to find out the effect of exercise on the brain. The book provides a detailed explanation of how different parts of the brain work on a biological level to carry out the everyday functions and what part of the brain is responsible for different tasks. We get to learn how the brain is able to function at a cellular level like how the ne ...more

Incredible read. Everyone knows the benefits of exercise on the muscles and heart but now studies have discovered what it does to the brain, which is even more impressive.

The last couple of years has had an explosion of Neuroscience books. What is even more unbelievable is that the researchers have actually decided to share what they are discovering in a way anyone can understand instead of the typical closed circle of academia.

To some extent the discoveries aren't surprising, but then it is al

This book is a review of much of the research that has been published in the past decade or so, on the subject of exercise's effects on the brain. It is an absolutely first-rate book. I have read a lot about how exercise improves one's mood. But I had not realized the many other benefits to one's brain, intelligence, memory, problem solving, that are induced by exercise. The very first chapter describes how a strong school exercise program has benefited an entire school district. Exercise can ac ...more

To be fair, I skimmed this book for bits that were relevant to me. I read chapter 3: Stress, very carefully. It was a revelation to discover that the body actually creates glucose as part of the stress reaction, and shuts down cells from processing it so that it remains available for immediate energy, leftover from back when stress was always physical danger.

All sorts of connections to my own health - made.

The big idea of the book is very simple: Physical activity is a necessary part of our evolution to develop ourselves both physically and mentally. John Ratey, the author, starts the book with a hypothesis that we have developed superior brains because we're creatures that need to move to find food. Adding on to that exercise keeps us sharp through several neuro-pathways that helps us learn the best ways to manage our food, predict how our environments work and remember all of this for the future ...more

As a gym teacher, I am all about movement. I want my kids to be active and engaged for as much of class as possible. But even though I was already on the exercise bandwagon, I had no idea how extensive the benefits of exercise really are. In Spark, John Ratey explains why the benefits of exercise to the heart, lungs, and muscles, are secondary to the benefits of exercise to the brain. The first chapter is the most engaging, where he shows how a few rogue school systems boosted test scores and lo ...more
Oh my god. According to this book I am a walking recipe for Alzheimer's disease. This is a book by a Harvard psychiatrist about the link between mental health and exercise. As life-long depression sufferer with not one, but two parents who suffer/ed from Alzheimer's, I'm pretty much in the exponentially high risk category for dementia. But there is hope, if I get off my ass and start exercising.

I'm torn on the number of stars I want to give this book. I love the message of the book and it has truly changed the way I think about exercise! = 4/5 stars. But, as a non-scientist, I felt bogged down by the (loooong) sections that tried to explain how certain processes work in the brain. = 2/3 stars.

4* to this book for making me run in the morning. Yes, (nearly) every day.

I used to find it extremely boring and exhausting in the past and, to tell the truth, I still do. But now I do it with a sense of mission to rewire the brain. The thing is that I am already quite sporty and I understand the importance of getting to the gym at least 3 times a week (yes, that often). But after this book, I also understood that exercise could be a kind of replacement therapy for a great many things that happe

It is a nice and refreshing read during a time where pharmacy, pill based therapy, is often over used putting life style change by the way side.

I absolutely loved this. Amazing information on fitness and American education. Listening to the miracle of feel good hormones and neurotransmitters that fire during exercise gave me the intellectual understanding of exercise I needed to help motivate me to be consistent in my fitness schedule. Learn faster, learn better, reverse aging, decrease anxiety, get happy, read Spark.

An excellent exercise motivator! This being a pop-science book it'll be most effective if you're a logically minded person or in need of some explicit reasons to overcome creeping apathy or procrastination. One of the best aspects of a book on exercise is that you can test and verify the essential ideas as they relate to your own experience; I often listened to the audiobook while jogging or at the gym. Knowing more about how something you're doing is good for you is an additional reward in itse ...more

Informative and motivational. There is so much good that exercise can do for a person, both physically (of course) and mentally; both immediately and over time. I didn't understand all the neurology mentioned in this book, but the author was good at clearly summarizing the scientific findings.

Exercise is good for the brain. Okay, that's credible, could you tell me more? The authors begin with a very promising anecdote about a school in Naperville. I find it compelling. Then they proceed to ramble through a supposed survey of the modern neuroscientific literature. This might be genius. It might be crap. And I can't tell after having read the book, and that's definitely for crap.

I am enormously sympathetic to the challenges of writing a scientific book for the lay public. It's hard. I

I like to move. I don't dread exercise, I enjoy it. My problem is that I tend to relegate exercise into the category of "fun" instead of "necessity". Because of this, I am always on the look out for ways to remind myself that exercise is essential. In that regard Spark is extremely handy. I don't like exercising because it is "healthy"; I find that reasoning way too wishy-washy for my brain to wrap around. I like looking good. But I suppose I'm just not shallow enough to devote my time to my own ...more

Ratey a clinical professor of psychiatry at Harvard lays down the proverbial smack of the effect of exercise. He breaks down a Naperville, Illnois school system that is serious about fitness and the outcomes it is getting. This is not your ordinary Physical Education course. Let me give you a hint, their minds are effected nearly as much as their bodies based on this activity.

This book spells out the variety of positive effects that exercise has on a person's brain. Ratey explains how the human brain has evolved to benefit in many ways from physical activity, including mood regulation, anxiety moderation, higher ability to learn, even staving off mental deterioration. He then details how exercise has benefitted particular subgroups, such as those with ADHD or depression, pregnant women, and the elderly. Despite discussing some unfamiliar neurochemical names, the narr ...more

This is the most important book you will never read! The research and its conclusions are mind blowing. If you just read the first couple of chapters you will start to move. Throughout the book the author repeatedly demonstrates that exercise is the best way to improve your life experience. This book could change the planet, if only everyone would read it.

“At every level, from the microcellular to the psychological, exercise not only wards off the ill effects of chronic stress; it can also reverse them. Studies show that if researchers exercise rats that have been chronically stressed, that activity makes the hippocampus grow back to its preshriveled state. The mechanisms by which exercise changes how we think and feel are so much more effective than donuts, medicines, and wine. When you say you feel less stressed out after you go for a swim, or even a fast walk, you are.” 17 likes
