Recruitment & Eligibility

• Status: Completed
• Sex: All
• Target Recruitment: 140

Inclusion Criteria

Clinically healthy and sedentary individuals. To classify the volunteers as sedentary was applied the Baecke questionnaire for epidemiological studies. The questionnaire included four questions about sport activities, eight about occupational activities and four about habitual leisure habits. According to the sum of scores of the questionnaire, the volunteers were classified as sedentary.
The volunteers should have a body mass index (BMI) between 18.5 to 24.9Kg/m2 and 25.0 to 29.9Kg/m2 in accordance with the World Health Organization classifications for eutrophics and overweight, respectively.

Exclusion Criteria

Smokers or former smokers; cardiovascular, respiratory, skeletal muscle or neuromuscular pathologies; cognitive deficits or difficulty in understanding maneuvers; sleep dyspnea, cyanosis, thoracic structural alterations, and infections in general in the previous six months.

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The respiratory muscle strength was measured by an aneroid manovacuometer[10 minutes after anthropometric measurements]

Secondary Outcome Measures

Name	Time	Method
To compare the maximal respiratory pressure with the predicted values. After the maximal inspiratory and expiratory pressures measurement were taken for each patient using an aneroid manovacuometer, these values were compared to the predicted values for the Brazilian population according to Neder et al. (1999). The predicted values were calculated for each patient utilizing the following formulas: MIP= -0.80 (age) + 119.7 + 0.48 (weight) and MEP = -0.81 (age) + 165.3.[After the subject did three repetitions of each maneuver with an interval of one minute between each repetition.]
