Primary Outcome Measures

Name	Time	Method
Different loads of inspiratory muscle training will produce different hemodynamic responses.;The loads of 30 and 60% produced different hemodynamic responses. The load of 30% generated a decrease in the systolic volume variable and the load of 60% increased cardiac output. The placebo load did not generate significant changes in any parameter.

Secondary Outcome Measures

Name	Time	Method
Secondary outcomes are not expected.
