title: Do patients with newly diagnosed type 2 diabetes have impaired physical fitness, and energy expenditures?
abstract: BACKGROUND
  The disease-related components such as physical fitness and daily energy expenditure may change in each progressive period of type 2 diabetes. The purpose of this study was to compare the maximal aerobic capacity (VO2 max), muscle strength, trunk flexibility, total energy expenditure, daily physical activity, resting metabolic rate (RMR), body composition, and body fat distribution in newly diagnosed type 2 diabetic patients with those of healthy controls.
  
  
  METHODS
  Eighty patients (40 male, 40 female) with type 2 diabetes and 80 (40 male, 40 female) controls were included in this study. All participants completed the measurements.
  
  
  RESULTS
  It was determined that the VO2 max, muscle strength, daily number of steps, and total energy expenditure were lower, and the body fat percentage, and central obesity were higher in male and female type 2 diabetic patients, when compared with the controls. In addition, the lean body mass was decreased in male diabetic patients, compared with the controls. The fasting plasma glucose showed negative correlations with the maximal aerobic capacity, daily number of steps, and muscle strength in the patients in both genders. RMR and trunk flexibility values were not significantly different between the patients and the controls in either gender.
  
  
  CONCLUSIONS
  We suggest that using exercise intervention especially comprised of strength training and aerobic activities, including not only daily slow activities but also moderate to vigorous activities, as a lifestyle modification in newly diagnosed type 2 diabetic patients might be helpful for the development of earlier and more successful illness management strategies.
