Modificazioni indotte dall’esercizio in forma di circuito su soggetti diabetici di tipo 2

INTRODUCTION: Exercise is considered one of the cornerstones of diabetes treatment, and several studies have demonstrated that exercise alone has clinical benefits, such as improved insulin sensitivity, reductions in glycated hemoglobin (HbA1c) and increased peak oxygen consumption (VO2peak). Physical inactivity is the fourth leading cause of death in the world and we must therefore take all possible solutions to increase the adoption and adherence to physical exercise. OBJECTIVE: To assess the effects of circuit training on HbA1c and VO2max (primary outcome) and several metabolic risk factors (blood pressure, body composition, body weight) and muscolar fitness, in subjects with type 2 diabetes, and to evaluate the training duration which is a factor that may improve adherence to physical exercise. RESEARCH DESIGN AND METHODS: Type 2 diabetic patients (n = 13) Underwent a circuit training program (8 weeks; 3 times per week). Before and after the intervention, HbA1c, cardiorespiratory fitness (VO2max), muscular strength and body composition were assessed. Pre-post intervention assessment were compared by a Wilcoxon non parametric test, while to meta-nalysis were performed in order to compare the VO2 and HbA1c changes with published studies. RESULTS: The circuit training program, significantly improved VO2max (+5,65%) (p
