Exercise Can Replace Insulin for Elderly Diabetics
Most old people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise
for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen
newspaper Berlingske Tidende on Monday.
Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center
for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30
percent,the newspaper reported.
This is equal to the effect most elderly diabetics get from their insulin medication today,it said.
Researchers had a group of non-diabetic men and a group of men with type Ⅱ,all more than 60 years of
age,exercise on bicycles six times a week for three months.After the three months the doctors measured
how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.
Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that
the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons.
"This means that the insulin works just as well for both groups.Physical exercise cannot cure people of
diabetes,but it can eliminate almost all their symptoms.At the same time it can put off the point at which
they have to begin taking insulin or perhaps completely avoid insulin treatment,"Dela was quoted as saying.
Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to
work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient
exercise.
Most diabetics realise that they have to watch their diet while remaining unaware of the importance of
exercise,Dela added.

第三篇Exercise Lowers Employers' Health CostsCompanies can save millions in health-care costs simply by encouraging their employees to exercise a little bit,researchers reported on Friday.They said obese（肥胖的）employees had higher health-care costs , but lowered those expenses by exercising just a couple of times a week-without even losing any weight.Feifei Wang and colleagues at the University of Michigan studied 23,500 workers at General Motors.They estimated that getting the most sedentary（惯于久坐的）obese workers to exercise would have saved about$790,000 a year,or about 1.5 percent of health-care costs for the whole group.Company-wide,the potential savings could reach$7.l million per year,they reported in the Journal of Occupational and Environmental Medicine.Of the whole group of workers,about 30 percent were of normal weight,45 percent were overweight（超重的）,and 25 percent were obese. Annual health-care costs averaged $2, 200 for normal weight,$2, 400 for the overweight,and$2, 700 for obese employees.But among workers who did no exercise,health-care costs went up by at least$100 a year,and were$3,000 a year for obese employees who were sedentary.But adding two or more days of light exercise一at least 20 minutes of exercise or work hard enough to increase heart rate and breathing一lowered costs by on average$500 per employee a year,the researchers found."This indicates that physical activity behavior could reduce at least some of the harmful effects of excess body fat,and in consequence,help lower the health-care costs,"Wang and colleagues wrote. How often should the employees exercise to help lower the health-care costs?A:At least seven days a week. B:At least twenty minutes a week.C:At least twice a week. D:At least once a week.

第一篇Walking to Exercise the BrainDo you think sitting and studying all the time will improve your grades?Think again.Getting some exer-cise may help,too.New research with old people suggests that taking regular walks helps them pay attention better than if they didn't exercise.Previous research had shown that mice learn,remember,and pay attention better after a few weeks of working out on a running wheel.Mice that exercise have greater blood flow to the brain than those who don't. Their brain cells also make more connections.Neuroscientists（神经科学家）from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task,and their answers were just as accurate as their less-fit peers,the researchers found.The fitter participants also had more blood flow to a part of theirbrain responsible for paying attention and making decisions.In a second study , 15 elderly people who completed a 6-month aerobic-training（有氧运动）course were faster at attention tasks compared with 14 seniors who just did stretching and toning exercises（韵律操）for the same amount of time.So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news for the elderly.The effects of exercising on the brains of younger people haven't been studied yet. Still,it can't hurt to take occasional breaks and go for a walk or run around with friends.Whatever you do,though,don't try to read and walk at the same time.You could end up hurting yourself!After taking exercise for a few weeks,the mice were found to have______________ A:higher blood pressureB:faster heartbeatC:more blood flow to the brain D:better appearance

第三篇 Smart ExerciseDoctors are starting to find more and more information that suggests a connection between exercise and brain development.Judy Cameron,a scientist at Oregon Health and Science University,studies brain development.According to her research,it seems that exercise can make blood vessels,including those in the brain,stronger and more fully developed.Dr. Cameron claims this allows people who exercise to concentrate better. As she says:"While we already know that exercise is good for the heart,exercise can literally cause physical changes in the brain."The effects of exercise on brain development can even be seen in babies.Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active.With babies,even a{ittle movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in the importance of exercise.She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses.They need to establish a connection between motion and memory.In this way,as they get older,children will begin to associate physical activity with higher learning,"says Margaret. Older people can beef up their brains as well.Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week.The exercise does not have to be very difficult,but it does have to increase the heart rate.Also,just like the motion for infants,exercise for older people should involve some complexity.Learning some new skills or motions helps to open up memory paths in the brain that may not havebeen used for a long time.For most people,any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood.And your brain can benefit from as little as two to three hours of exercise a week. To be beneficial,exercise for older people shouldA:be done in a group. B: be done on a daily basis.C: involve great difficulty. D:increase the heart rate.

第三篇Exercise Can Replace Insulin for Elderly DiabeticsMost old people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.This is equal to the effect most elderly diabetics get from their insulin medication today,it said.Researchers had a group of non-diabetic men and a group of men with type Ⅱ,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons."This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms.At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,"Dela was quoted as saying.Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise.Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.To what a degree have diabetics to exercise in order to achieve the desired effect?A:To the degree where they begin to sweat.B:To the degree where they feel exhausted.C:To the point when they feel thirsty.D:To the point when they have to take insulin.

What Is Insulin-dependent Diabetes?When you eat,your body takes the sugar from food and turns it into fuel.______(46)Your body uses glucose for energy,so it can do everything from breathing air to playing a video game.But glucose can't be used by the body on its own-it needs a hormone called insulin to bring it into the cells of the body.Most people get the insulin they need from the pancreas,a large organ near the stomach?The pancreas makes insulin;insulin brings glucose into the cells;and the body gets the energy it needs.When a person has insulin一dependent diabetes,it's because the pancreas is not making insulin.So someone could be eating lots of food and getting all the glucose he needs,but without insulin,there is no way for the body to use the glucose for energy.______(47)You may have heard older people talk about having diabetes,maybe people of your grandparents'age.Usually,this is a different kind of diabetes called non一insulin一dependent diabetes.It can also be called Type 2 diabetes,or adult-onset diabetes.______(48) When a kid is diagnosed with juvenile(insulin-dependent)diabetes,he will have that type of diabetes for his whole life.It won't ever change to non-insulin-dependent diabetes when he gets older.Scientists now think that a person who has juvenile diabetes was born with a certain gene or genes that made the person more likely to get the illness.______(49)Many scientists believe that along with having certain genes,something else outside the person's body, like a viral infection,is necessary to set the diabetes in motion by affecting the cells in the pancreas that make insulin.But the person must have the gene(or genes)for diabetes to start' out with一this means you can't get diabetes just from catching a flu,virus,or cold.And this type of diabetes isn't caused by eating too many sugary foods,either.Diabetes can take a long time to develop in a person's body-sometimes months or years?Another important thing to remember is that diabetes is not contagious.______(50)______(47)A:Genes are something that you inherit from your parents,and they are in your body even before you're born.B:This sugar-fuel is called glucose?C:It may be possible to beat insulin resistance through lifestyle changes.D:You can't catch diabetes from people who have it,no matter how close you sit to them or if you kiss them.E:The glucose can't get into the cells of the body without insulin.F:When a person has this kind of diabetes,the pancreas usually can still make insulin,but the person's body needs more than the pancreas can make?

第三篇Walking to Exercise the BrainDo you think sitting and studying all the time will improve your grades?Think again?Getting some exer-cise may help,too.New research with old people suggests that taking regular walks helps them pay attention better than ifthey didn't exercise.Previous research had shown that mice learn,remember,and pay attention better after a few weeks ofworking out on a running wheel.Mice that exercise have greater bl0od flow to the brain than those who don't.Their brain cells also make more connections.Neuroscientists（神经科学家）from the University of Illinois at Urbana-Champaign wanted to find out ifthe same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computerkeys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task,and their answers were just as accurate astheir less-it peers,the researchers found.The fitter participants also had more blood flow to a part of theirbrain responsible for paying attention and making decisions.In a second study , 15 elderly people who completed a 6-month aerobic-training（有氧运动）course werefaster at attention tasks compared with 14 seniors who just did stretching and toning exercises（韵律操）for the same amount of time.So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news for the elderly.The effects of exercising on the brains of younger people haven't been studied yet.Still,it can't hurt to take occasional breaks and' go for a walk or run around with friends.Whatever you do,though,don't try to read and walk at the same time.You could end up hurting yourself!Walking regularly helps elderly people___________.A:lose weightB:become happierC:concentrate betterD:look younger
