Introduction: Diabetes mellitus type 2 (T2DM) is a chronic disease constituting a health problem in the world and particularly in Tunisia. Lack of physical activity and obesity are risk factors for T2DM. Therefore, exercise training (ET) is important for both preventive and curative action. The aim of the present study was to evaluate the effects of exercise training on sedentary patients with uncontrolled T2DM based on different parameters.
Material and methods: Six male patients aged 40 to 55 years with T2DM were included. The training program lasted 8 weeks three times per week, with a 60-minute structured exercise session. The training progressed gradually in duration and intensity. The evaluation of the effects of ET in T2DM patients was based on anthropometric parameters, submaximal aerobic capacity and plasma biomarkers. The significance level was set at a probability level ≤ 0.05. Results: Mean age, weight, duration of diabetes, HbA1c and fasting glycemia were respectively 48.5± 2.7 years, 83.58±8.75 kg, 9.6±4.9 years, 10.15±1.42 % and 8.41±3.28 mmol/l at baseline. Waist circumference decreased significantly after ET (4.8±3.7 cm, p<0.05). There was an improvement in submaximal aerobic capacity (6-min walk test) with significant increase in 6-min walk distance (61±27 meters, p <0.05). After ET, a significant increase in HDL-Cholesterol level was found (0.41± 0.14 mmol/L, p<0.05).
Conclusion: The present study showed that 8 weeks of combined exercise training was beneficial for T2DM patients. However, the improvements of certain parameters would be more important if patients had a rehabilitation program.
