Researchers had a group of non-diabetic men and a group of men with type II diabetes, 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 make use of 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 made as good use of insulin as the healthy non-diabetic persons. “This means that the insulin works just as well for both group. 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,” Dela said. Insulin is a hormone produced by the pancreas(胰腺) , controlling sugar in the body and is used against diabetes. Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise. Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise, Dela added. 第6题：What is the effect of exercise on elderly people with type II diabetes？ A．It can worsen their symptoms.
