How many steps does it take to avoid a heart attack?

Researchers find out.

 

  Walking can lower your risk of having a heart attack, as any doctor will tell you. Now scientists have found out exactly how many steps it takes to keep your ticker healthy.

  Even people who are at risk for diabetes can cut their risk for heart-related events like a heart attack or stroke by 8%.

  In new research published in the journal Lancet, scientists report that among people with early signs of pre-diabetes, taking an extra 2,000 steps a day – the equivalent of 20 minutes of moderate-paced walking – helped them lower their chances of heart problems.

  The research team looked at data from 9,306 adults from 40 countries participating in a trial called NAVIGATOR. All of the volunteers were assigned to a program to lose weight and exercise 150 minutes a week. They were given pedometers that they wore for a week at the beginning of the study, and again a year later.

  Using statistical modeling, the researchers studied the association between the number of steps the participants took on average and their relative risk for heart events in that year, accounting for potentially confounding factors that could influence heart disease rates such as diet and the participants’ previous history of heart issues.

  Two thousand steps seemed to be the magic number. Even before the study began, for every 2,000 steps a day one participant tended to walk on average compared to another, he enjoyed a 10% lower rate of heart problems by the end of the year. During the study year, there was an additional 8% lower risk of heart disease for every 2,000 steps walked a day.

  That should be encouraging news to those who have added exercise to their daily routine. You don’t have to take your doctor’s word for it — now there’s pretty convincing data on exactly how much walking it takes to avoid heart disease.

De acordo com o texto,

[1] The first

hamburger created by scientists in a lab

has been recently presented in London.

The burger, which cost over 300,000

[5] dollars to cultivate, originates from stem

cells that were taken out of

the shoulder of a cow. The result was

revealed in front of food and health

experts and televised across the Internet.

[10] It took food scientists three months

to raise 20,000 tiny pieces of meat

to create one single hamburger. Stem

cells were reproduced and, over a period

of time, created their own muscles. Mark

[15] Post, scientist at a Dutch University and

responsible for the project, has

been researching this method for a long

time. He says that the job was

a tricky one because it is important to

[20] keep the cells healthy and not let

any pollution get into them. Food experts

who tasted the new hamburger said that it

felt like meat but it was very lean and

without fat which normally changes the

[25] taste. Biting into it felt like a real burger,

but it wasn’t as tasty because salt and

pepper were missing. The experiment

showed that creating food in a lab is a

possible solution for the world’s food

[30] problems. Large quantities of meat could

one day be

made artificially without raising millions of

animals around the world. Those

who welcome such a method say that we

cannot produce enough meat in the future

and such a new method could be an

alternative.

Com base no texto, analise as seguintes assertivas: 
 
I - O hambúrguer foi desenvolvido com células tronco retiradas do ombro de várias vacas.
II - Especialistas disseram que o hambúrguer artificial parece de fato com carne.
III - O hambúrguer produzido, apesar de artificial, era muito saboroso.
IV - O método desenvolvido permitirá que diminua a criação de gado no mundo.
V - De acordo com as previsões de Mark Post, o hambúrguer poderá ser produzido em escala, a
partir do ano que vem.
 
Assinale a alternativa correta.

[1] More and more

television manufacturers are producing

Smart TVs. Although they differ in some

ways most of them use the same

[5] technology. Smart TVs can be

connected to the internet using a setup

box, a cable or wireless adapter. As more

and more broadcasting companies are

showing videos on demand Smart. TVs

[10] are an investment for the future.

Some decades ago watching television

was a completely different experience. If

you were lucky you had a handful of

channels you could watch. Depending on

[15] your rooftop antenna and the signal you

got, reception was sometimes bad and

during storms the signal was lost

altogether. In the 1970s cable TV gave

viewers a choice of several different

[20] programs, not only from the local area.

The arrival of video recorders allowed

viewers to record their shows during the

nighttime or while they were on holidays.

Satellite television in the 80s and 90s

[25] gave people access to hundreds of TV

channels from around the world. In the

last decade Internet television has been

growing rapidly.
