Abstract

Introduction: obesity affects millions of people, mainly interfering with cardiac autonomic modulation (CAM) and functional capacity. Resources capable of assisting in the treatment of obesity should be studied. The effects of whole-body neuromuscular electrical stimulation (WBS) have been increasingly studied, but not yet been elucidated the effect of WBS on CAM and functional capacity in the obese. Objective: to verify the acute effects of WBS on MAC and functional capacity in the obese population, and to secondarily the impact of the degree of obesity on the effects of WBS. Methodology: 20 obese (age between 18 to 40 years) will be evaluated. All will perform the initial evaluation: anamnesis, physical activity level (Baecke's questionnaire), body composition (bioimpedance), cardiorespiratory evaluation for 5 min with metabolic system. After the subjects will be randomized to receive the WBS or Sham session, with an approximate duration of 20-minute, after 30 min the cardiorespiratory evaluation will be remade. In other day, will be CAM assessment through of heart rate variability (HRV) analysis, at rest for 10 min, after postural change (10 min), and the WBS or Sham again, and immediately after reassessment of CAM as previously performed. Expected results: WBS is expected to produce positive acute effects on CAM and cardiorespiratory capacity. In addition, according to the principles of electrostimulation, it is expected that individuals with lower degrees of obesity present higher gains. (AU)
