Brief Summary

This study investigated the effects of an inspiratory muscle training (IMT) program on the respiratory muscle strength and resistance and the aerobic physical performance (PP) of handball athletes. Nineteen male athletes took part in the study, allocated at random into the experimental group (EG, n=10) and the placebo group (PG, n=9), aged 19±1 and 22±5 years old, respectively. The respiratory muscle strength (RMS) was evaluated by measuring the maximum inspiratory and expiratory pressures (MIP and MEP, respectively), the muscular respiratory resistance was evaluated by maximum voluntary ventilation (MVV) and the aerobic PP by applying the cardiopulmonary exercise test. Subsequently the volunteers were submitted to an IMT protocol 5 times a week for 12 weeks.
