This Is Your Brain on Exercise: Why Physical Exercise (Not Mental Games) Might Be the Best Way to Keep Your Mind Sharp

Resultado de imagem para brain exercise

In the United States and the UK, we've seen the emergence of a multibillion-dollar brain training industry, premised on the idea that you can improve your memory, attention and powers of reasoning through the right mental exercises. You've likely seen software companies and web sites that market games designed to increase your cognitive abilities. And if you're part of an older demographic, worried about your aging brain, you've perhaps been inclined to give those brain training programs a try. Whether these programs can deliver on their promises remains an open question--especially seeing that a 2010 scientific study from Cambridge Universityand the BBC concluded that there's "no evidence to support the widely held belief that the regular use of computerised brain trainers improves general cognitive functioning in healthy participants..."
And yet we shouldn't lose hope. A number of other scientific studies suggest that physical exercise--as opposed to mental exercise--can meaningfully improve our cognitive abilities, from childhood through old age. One study led by Charles Hillman, a professor of kinesiology and community health at the University of Illinois, found that children who regularly exercise, writes The New York Times:
displayed substantial improvements in ... executive function. They were better at “attentional inhibition,” which is the ability to block out irrelevant information and concentrate on the task at hand ... and had heightened abilities to toggle between cognitive tasks. Tellingly, the children who had attended the most exercise sessions showed the greatest improvements in their cognitive scores.
And, hearteningly, exercise seems to confer benefits on adults too. A study focusing on older adults already experiencing a mild degree of cognitive impairment found that resistance and aerobic training improved their spatial memory and verbal memory. Another study found that weight training can decrease brain shrinkage, a process that occurs naturally with age.
If you're looking to get the gist of how exercise promotes brain health, it comes down to this:
Exercise triggers the production of a protein called brain-derived neurotrophic factor, or BDNF, which helps support the growth of existing brain cells and the development of new ones.
With age, BDNF levels fall; this decline is one reason brain function deteriorates in the elderly. Certain types of exercise, namely aerobic, are thought to counteract these age-related drops in BDNF and can restore young levels of BDNF in the age brain.
That's how The Chicago Tribune summarized the findings of a 1995 study conducted by researchers at the University of California-Irvine. You can get more of the nuts and bolts by reading The Tribune's recent article, The Best Brain Exercise May be Physical. (Also see Can You Get Smarter?)
You're perhaps left wondering what's the right dose of exercise for the brain? And guess what, Gretchen Reynolds, the phys ed columnist for The Times' Well blog, wrote a column on just that this summer. Although the science is still far from conclusive, a new study conducted by The University of Kansas Alzheimer’s Disease Center found that small doses of exercise could lead to cognitive improvements. Writes Reynolds, "the encouraging takeaway from the new study ... is that briskly walking for 20 or 25 minutes several times a week — a dose of exercise achievable by almost all of us — may help to keep our brains sharp as the years pass."

A Golpes de Martelo (por Rogério Rocha)


Meu martelo constrói a incompletude.
Meu martelo trabalha com afinco,
Destrói o mundo com seu golpe rude.
Meu martelo cria e urde, desafia e
Emudece as formas que surgem,
Mas habita na fala das pedras
Desamparadas do ente mais duro.

Meu martelo titânico destrói e devassa,
Burila e avassala rochas densas,
De natureza inconcussa e magmática.

Bate sobre o solo com firmeza instrumental.
Absorve-se no absurdo que é bater no infinito,
Despejar no monolito a frieza do seu grito magistral.

O arquiteto noviço, o artífice decrépito, o reles escultor,
Coletam lascas, coletam nesgas, rastejam na praça
Em busca dos restos do objeto perfeito que esculpo.

Um ruído surdo invade os orbes celestes,
devora o mundo, prefere os ataques lascivos,
os dedos massivos do pai dos tormentos.

Meu martelo espanca o ilusório;
Meu martelo trabalha com fúria
E detona todo vulto civilizatório.
Meu martelo desarma, num gesto,
A solene ambição dos que regem
O processo nefasto do estar à mão.

Meu martelo profético desfaz e arrasa,
Com golpes potentes, enormes pancadas,

As torres maciças que o templo resguarda.

"Símbolo" (por Rogério Rocha)

Rogério Rocha
Símbolo


A vida dentro da vida
guardada n’alma,
sorvida da aurora
das nossas alegrias.

O símbolo dentro do símbolo.
A guarda do sagrado,
O império dos segredos,
Instado a dizer-nos
No não dito, no não visto,
No sim, no não, no íntimo.

Somos sonho, somos signo,
Somos tempo, somos símbolo.

O vermelho do sangue
Na pele brotando,
A ferida nefasta
Nascida de um parto,
De um grito, de um fato.
Um sinal que emite sentidos.
Um som inaudível, a princípio,
E no princípio, ruídos ao fundo.

A voz da memória, o passado em jogo,
O sinal do princípio no crepitar do fogo.
No mais antigo do antigo a figura perene,
A dizer, no sempre, o que queremos.

A esfinge nos atinge: Kerub.

O mistério de ser gente,
De ser corpo, de ser homem.
O olhar que nos fala,
O corpo que nos fala,
O silêncio que nos fala,
A paixão que nos consome.

A gramática do ser
Abundante, a mostrar,
Apontar, consignar,
Uma physis constante.

Somos sonho, somos signo,
Somos tempo e somos símbolo.
Ainda assim, nos importa
Saber ler nos símbolos
A linguagem dos túmulos,
A voz dos narradores,
A letra dos pergaminhos,
O som dos arredores.

Fragmentos de um tempo
Adormecido.
