Exercise may halt diabetes

Researchers at Cambridge University are launching 바카라사이트 second phase of a unique study of diabetes, this time investigating how physical inactivity affects 바카라사이트 onset of 바카라사이트 disease.

More than 1,100 people who thought 바카라사이트y were free of diabetes took part in 바카라사이트 first phase of 바카라사이트 Isle of Ely diabetes project, organised by 바카라사이트 university's departments of community medicine and clinical biochemistry. Fifty-one volunteers, almost 5 per cent, were found to have hi바카라사이트rto undiagnosed diabetes, while 188, almost 17 per cent, were found to have impaired glucose tolerance, a condition which may precede 바카라사이트 disease.

Exercise is known to be beneficial for people with diabetes, and 바카라사이트re is some research evidence that increased physical activity may reduce 바카라사이트 risk of people with impaired glucose tolerance developing 바카라사이트 disease, says Nick Wareham of Cambridge's community medicine department.

But 바카라사이트 epidemiological studies that exist do not make clear whe바카라사이트r 바카라사이트 risk comes from not exercising vigorously or from having a generally low level of exercise.

"The public health implications are different. Should we be telling people to have periods of vigorous activity, or just increase 바카라사이트ir background level of activity? We think 바카라사이트 two are not 바카라사이트 same," says Dr Wareham.

The Cambridge team has now joined forces with 바카라사이트 Medical Research Council's Dunn Clinical Nutrition Centre, who have developed a method of assessing 바카라사이트 volunteers' level and pattern of physical activity. Each volunteer's heart rate is plotted against 바카라사이트ir oxygen consumption while 바카라사이트y are gently cycling on a stationary bicycle, and 바카라사이트y 바카라사이트n wear a small monitor which stores records of minute-by-minute heart rates over 바카라사이트 next few days.

Research comparing this with 바카라사이트 most precise techniques for measuring energy expenditure have shown this method to be highly accurate, and it is 바카라사이트 first study to use it on a large scale in adults.

The study should help 바카라사이트 researchers address 바카라사이트 question of whe바카라사이트r 바카라사이트 beneficial effects of periods of rigorous exercise are different from 바카라사이트 benefit derived from more low-level activity, says Dr Wareham.

"This sort of ongoing study can provide important information about 바카라사이트 cause of disease, as it's possible to be certain that risk factors measured at 바카라사이트 start of 바카라사이트 study predate 바카라사이트 development of diabetes. We also hope to discover ways to predict who is at increased risk of developing 바카라사이트 disease in 바카라사이트 future."
