Inclusion criteria
Inclusion criteria: The study included female subjects (since obesity waiting list is formed for the most part by women and so there is no contamination of data and bias due to low number of male patients) with: Sheet physical therapy preoperative evaluation completed; subjects with obesity class II and III, have BMI> 35 and <60 kg / m2); the age and / or equal to 18 and less than and / or equal to 59 years; Sedentary individuals or assets; no deficit in the locomotor system and / or balance disorders reported or detected on physical examination without changes in heart function (released by cardiologist by certified to perform physical exercise), and acceptance and signing of the informed consent and informed .
Exclusion criteria
Exclusion criteria: The exclusion was determined when the subjects did not properly perform the ventilatory evidence presented spirometric function not preserved by FEV1 / FVC <0.70, present musculoskeletal limitations or pain preventing the holding of the test, submit a confirmed diagnosis of some heart disease and asthma
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find that obese have as main outcome a greater consumption of oxygen. In addition, a higher heart rate, greater minute ventilation, anaerobic threshold found later and a lower subjective perception of effort in the treadmill test and ramp protocol, verified by means of the different protocols of cardiopulmonary exercise test performed on treadmill or exercise bike having each evaluation test average duration of 8 to 12 minutes from the observation of a variation of at least 5% in the measurements between the different protocols performed. The measurements and parameters used in the evaluation will be based on prediction equations already used in the literature of% of oxygen consumption,% of maximum frequency,% of minute ventilation (Neder et al., Wasserman et al) | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find that obese have a lower test duration ramp protocol performed on a treadmill, through analysis of five different exercise stress testing protocols from the comparison of the final time of the test and the observation of a variation of at least 5% in the measurements between the different protocols performed;We expect that when analyzing the behavior of the oxygen kinetics curve during the constant loading protocols 25% above and 25% below the anaerobic threshold in the two types of distinct ergometer, treadmill and bicycle no differences were found in the responses, observed by increasing the curve, of at least 5% to quantify its magnitude in obese women through a bi-exponential mathematical analysis model | — |
