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.
Physical exercise may increase the body ability to utilise insulin by______.
A.70 percent
B.30 percent
C.60 percent
D.only a few percent

On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.
Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they’d rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control.
Tim knew it would soon be swallowed by the waves."Everything went quiet in my head," Tim recalls(回忆). "I was trying to figure out how to swim to the boys in a straight line."
Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!"
A. To take in enough fresh air.
B. To consider turning back or not.
C. To check his distance from the boys.
D. To ask the boys to take down the umbrella.
