Resposta pressórica a um programa de treinamento físico aeróbio em indivíduos diabéticos tipo 2

Abstract

The Diabetes Mellitus is a multiple etiology syndrome characterized by chronic hyperglycemia and high levels of oxidative stress, frequently accompanied by arterial hypertension and endothelial dysfunction. Aerobic training promotes blood pressure (BP) reduction and improvement of its autonomic control. Our hypothesis is that the pressure loads are also benefited by training. To investigate the effects of an aerobic training program in BP clinical, outpatient and in the components of pressure loads in diabetics. The study was composed of 13 type 2 diabetics, being seven men, with 54 ± 6.5 years old, BMI 29 ± 7, randomly divided into exercise group (GEX; n=6) and control group (CG; n=7). The GEX was understood a 12 week aerobic training program, with three weekly sessions of 20 to 60 minutes and progressive intensity (45 to 85% of Vo2max). Before and after the program, the volunteers performed the Blood Pressure outpatient monitoring, ergospirometric testing, anthropometric evaluation, blood collection, and each two weeks a clinical BP. The CG volunteers had only controlled their intervening variables. In GEX, the decrease of BP systolic in sleep presented a significant increase of 3% (p=0.01) and also 3% in the diastolic (p=0.05). The Clinical BP showed descriptive reduction. The behavior was repeated in the pressure load and in the morning rise. A 12 week aerobic training program promoted increased of BP decrease in sleep of type 2 diabetic patients.
