Brief summary
The purpose of this study, therefore, will be evaluate whether 12 weeks of aerobic physical training program of moderate-intensity can modify the heart rate variability (HRV) and functional capacity in severely obese women four months after gastric bypass surgery (GBS). We hypothesized that, the application of aerobic physical training after GBS can promote increase of functional capacity in severely obese women after bariatric surgery. A secondary hypothesis is that the aerobic exercise training can positively impact on HRV.
Interventions
All patients will undergo a clinical examination prior to the surgery, which will be done by gastroenterologist and a cardiologist physician (anamnesis, resting 12-lead electrocardiogram, endoscopy and blood analysis used to determine hemoglobin, triglycerides, total cholesterol and fractions: low-density lipoprotein - LDL and high-density lipoprotein - HDL, fasting glucose and uric acid). In addition, anthropometric data, spirometric measurements, regular physical activity pattern, six-minute w
All patients will undergo a clinical examination prior to the surgery, which will be done by gastroenterologist and a cardiologist physician (anamnesis, resting 12-lead electrocardiogram, endoscopy and blood analysis used to determine hemoglobin, triglycerides, total cholesterol and fractions: low-density lipoprotein - LDL and high-density lipoprotein - HDL, fasting glucose and uric acid). In addition, anthropometric data, spirometric measurements, regular physical activity pattern, six-minute walk test (6MWT) and R-R intervals will be collected before and 4 months after gastric bypass surgery. One month after surgery, patients will be randomly assigned to two groups: 1) control and 2) physical training. The aerobic exercise training program consist of: 1) initial five minutes of stretching the upper and lower limbs (hamstrings, quadriceps, calves, shoulders) and diaphragmatic breathing and awareness of proper posture in front of a mirror in the position standing and sitting; 2) five minutes of heating on a treadmill at 3 km/h; 3) forty minutes of walking on treadmill with speed and inclination varying according to the behavior of heart rate (HR). These forty minutes will be separated into four steps of 10 minutes each: 1 degree) intensity of exercise in which the HR remained at 50% of HR maximal; 2 degrees) 60% of HR maximal; 3 degrees) 70% of HR maximal and 4 degrees) maintaining 70% of HR maximal; 4) recovery of one minute at 3 km/h and; 5) ten minutes of the same initial stretching and diaphragmatic breathing. HR and blood pressure will be obtained at the beginning of the session, at the end of each step, recovery and at the end of session. The sessions will be held during one hour on alternate days: 3 times per week, for 12 weeks, a total of 36 sessions, a period of 3 months. The sessions will be performed individually and supervisioned by physiotherapist.
