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.
选项 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.
答案A
解析由文章第一段中“Mostoldpeoplewithso-calledtypeIIdiabetescouldstoptakinginsuliniftheywoulddobriskexercisefor30minutesjustthreetimesaweek...”一可知，一周三次活泼轻快的锻炼就能让大多数IT型糖尿病的老年患者停止使用胰岛素，故选Co
由文章第二段中“...physicalexercisecanboostthebody'sabilitytoutiliseinsulinby30percent...”可知，体育锻炼能将身体利用胰岛素的能力提高30%，故选B
由文章第四段中“Researchershadagroupofnon-diabeticmenandagroupofmenwithtypeⅡ,allmorethan60yearsofage”可知，两组调查对象分别为未患糖尿病的老年人和II型糖尿病的老年患者，故选D。
由文章倒数第二段中“Delasaidthattoachievethedesiredeffectdiabeticsneedonlyexer-cisetothepointwheretheybegintoworkupasweat.”可知，体育锻炼只要达到出汗的程度就能起作用，故选A。
由文章最后一段中“Mostdiabeticsrealisethattheyhavetowatchtheirdietwhileremainingunawareoftheimportanceofexercise.”可知，大多数糖尿病患者都知道必须注意饮食，但却并不知道体育锻炼的重要性，故选C。
