Article Abstract:
Doctors should encourage all patients with type 2 diabetes to exercise on a regular basis. Researchers gave 1,263 men with type 2 diabetes a complete physical exam including tests of cardiorespiratory fitness and then followed them for up to 25 years. The men with low cardiorespiratory fitness who did not exercise regularly had twice the risk of death than men with high cardiorespiratory fitness who exercised regularly.

Article Abstract:
Poor physical fitness and obesity may increase the risk of developing impaired fasting blood glucose control and type 2 diabetes. Researchers studied 8,633 men without diabetes for six years, during which 593 men developed impaired fasting glucose and 149 men became diabetic. Physical fitness was determined by exercise testing on a treadmill. The risk of impaired fasting glucose was 90% higher, and the risk of diabetes was nearly 4 times as high, in the least-fit men, compared to the most-fit men. A family history of diabetes, obesity, high blood pressure, and older age also increased the risk of diabetes.

Article Abstract:
Low cardiorespiratory fitness appears to be a risk factor for death from cardiovascular disease (CVD). Cardiorespiratory fitness is a marker for physical activity. Researchers analyzed CVD mortality and mortality from all causes in 25,714 men. Men who were overweight or obese and had risk factors for CVD had higher death rates than normal-weight men without CVD risk factors. CVD risk factors included diabetes, high cholesterol levels, hypertension, smoking and low fitness. Even after adjusting for other CVD risk factors, low fitness was an independent risk factor for death in all men regardless of weight.
