Abstract
Introduction: Combined aerobic and resistance training (RT) has been reported to enhance insulin sensitivity and to improve glycemic control, lipid profile and blood pressure [1]. Based on this evidence the American Diabetes Association guidelines have refined the recommendations on the desired types, amounts, and intensities of aerobic physical activity for diabetic people. So far people with type 2 diabetes should be encouraged to perform RT in the absence of specific contraindications. The aim of this study was to evaluate the effects of RT on walking strategy, in a group of type 2 diabetic patients with peripheral arterial disease (PAD) and without PAD (NoPAD). Methods: 17 subjects participated in the study (mean age 61±4; mean BMI 28±5): 5 healthy (control subjects (CS)), 4 diabeticwithPAD(PADS) and8NoPADsubjects. Patientswereasked to walk on a treadmill for 40min: the session started (Warm Up) and ended (Cool Down) with a period of 2.5min at 2km/h and no inclination, while central part scheduled 35min at a speed of 4km/h, with an inclination of 2% (for total 3.3 METS) (Central Part). Plantar pressure parameters were acquired with Software Pedar X (Novel version 20). Following parameters were analysed bilaterally: max duration of stance period,max area of stance, peak of Ground Reaction Force, peak of pressure and its position (Matlab 2010a). The acquisition was then repeated after 10 weeks. Meanwhile subjects were asked to walk for at least 150min per week and they were provided of a pedometer in order to allow recording their activity (Newfeel Oxilane). Results: OneWay Anova (SPSS Statistic 19) have shown significant differences on both Peak of Pressure and temporal parameters in PAD with respect to NoPAD (p<0.05) and control group. PADS shown a Peak of Pressure positioned earlier than control group (p=0.02) and later than diabetic group (p=0.00005). These differences were disappeared after 10 weeks of walking. Correlation analysis highlighted positive correlation between following variables:
