Primary Outcome Measures

Name	Time	Method
A greater reduction in systolic, diastolic and mean blood pressure, as measured by plethysmography, is expected immediately after and within 60 minutes after the respiratory muscle training maneuver comparing the difference between the strength protocol group to the the endurance protocol group.

Secondary Outcome Measures

Name	Time	Method
A greater increase in heart rate, as measured using a cardiofrequencimeter, is expected immediately after and within 60 minutes after the respiratory muscle training maneuver comparing the difference between the strength protocol group to the the endurance protocol group.;A greater increase in myocardial work, stimated by doble-product (measured by the multiplication of systolic blood pressure by heart rate), is expected immediately after and within 60 minutes after the respiratory muscle training maneuver comparing the difference between the strength protocol group to the the endurance protocol group.
