　　Exercise Can Replace Insulin for Elderly Diabetics

　　Most older 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 per cent, the newspaper reported。

　　This is equal to1 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 than60 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.2

　　Associate Professor3 Dr.  Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilization 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, 4 but it can eliminate almost all their symptoms. At the same time it can put off5 the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment," Dela was quoted as saying.6

　　Insulin isa 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 up7 a sweat, but that the activity has to be maintained since it wears off8 after five days without sufficient exercise。

　　Most diabetics realize that they have to watch their diet while remaining unaware of9 the importance of exercise, Dela added。

　　译文：老年糖尿病患者进行体育锻炼可以取代胰岛素治疗

　　哥本哈根的《贝林时报》周一刊登了一则最新医疗研究结果称，大多数II型老年糖尿病患者只要每周坚持三次轻快的体育锻炼，每次30分钟，都可以不用注射胰岛素。

　　报道称，哥本哈根市中心医院Rigshopspitalet肌肉研究中心对糖尿病人进行测试，结果显示体育锻炼能将身体利用胰岛素的能力提高30%。

　　据说，这一结果和大多数老年糖尿病患者每天接受胰岛素治疗的疗效相同。

　　研究人员挑选了一组非糖尿病患者，一组II型糖尿病患者，都是60岁以上的男性。这些被试者每周骑自行车锻炼六次，并持续了三个月。三个月后，医生测量出被试者肌肉能够利用的血糖总量，以此作为测量他们的胰岛素工作状况如何的标志。

　　肌肉研究中心副教授弗莱明·德拉医生称，实验结果显示，进行体育锻炼的糖尿病患者胰岛素利用率和那些没有锻炼的健康人胰岛素利用率一样高。

　　“这就意味着，两组被试者的胰岛素都是正常工作的。体育锻炼不能治好患者的糖尿病，但是能最大限度地消除患者症状。另外，即使患者不得不接受胰岛素治疗，体育锻炼也能尽量推迟这一临界点，甚至有可能完全避免实施胰岛素治疗。”德拉医生的话像格言一样被人们所引用。

　　胰岛素是胰腺分泌的一种激素，可以控制体内血糖，预防糖尿病。

　　德拉解释说，糖尿病患者只需锻炼到出汗的程度皆可达到理想的效果。同时他还强调，这种锻炼必须坚持，如果五天没有进行有效锻炼，效果就会消失。

　　德拉还补充说，大多数糖尿病患者意识到他们必须控制饮食，却忽略了体育锻炼的重要性。
