The effects of Internet

To compare the effects of Internet-based exercise on glycaemic control, blood lipids, body composition, physical activity level, functional capacity, and quality of life with supervised group exercise in patients with type 2 diabetes. Single-blind, randomized controlled study. A Faculty of Health Sciences. A total of 65 patients with type 2 diabetes (47 women, 18 men). Group A (n？=？22), control group – physical activity counselling once with a brochure. Group B (n？=？22), supervised group-based exercise, three days per week for eight weeks. Group C (n？=？21), Internet-based exercise following the same programme via a website. Primary outcomes – glycosylated haemoglobin, fasting blood glucose, high-density and low-density lipoprotein, triglyceride, and cholesterol. Secondary outcomes – waist and hip circumferences, body mass index, number of steps, six-minute walking test, and Euro-Quality of Life-5 Dimension. After treatment, glycaemic control (mean change for Group B; Group C; –0.80%, –0.91%, P？=？0.003), waist circumference (–4.23？cm, 5.64？cm, P？=？0.006), and quality of life (0.26, 0.15, P？=？0.013) significantly improved in both training groups compared with the control group. Fasting blood glucose (–46.86？mg/dL, P？=？0.009) and hip circumference (–2.7？cm, P？=？0.011) were significantly decreased in Group B and total cholesterol (–16.4？mg/dL, P？=？0.028), six-minute walking distance (30.5？m, P？=？0.01), and number of steps (1258.05, P？=？0.023) significantly improved in Group C compared with control group. Group B and Group C changed with equal magnitude. In type 2 diabetes, supervised group-based and Internet-based exercise can improve equally glycaemic control, waist circumference, and quality of life, and both are better than simply counselling
