Conditions

Respiratory Chronic obstructive pulmonary disease with mild to moderate airways obstruction, medically stable with no recent exacerabations

Interventions

expiratory muscle training

inspiratory muscle training

Eligibility

Sex/Gender

Male

Inclusion criteria

Inclusion criteria: All of them were smoker with an index of less than 400 (mild to moderate degree). forced expiratory volume in the first second (FEV1) ¿ 50- 70% of the predicted value

Exclusion criteria

Exclusion criteria: severe airflow obstruction (FEV1< 50% of the predicted, Chest infection in the previous 2 months chronic respiratory failure who may need supplemental O2, or had CO2 retention drugs such as corticosteroids or anabolic steroids with in the previous 3 months which could affect exercise capacity cardiac disease, neurological or musculoskeletal disorders, pulmonary hypertension and mental disorders that could affect cooperation

Design outcomes

Primary

Measure	Time frame
respiratory muscle strength;respiratory muscle strength was measured using spirometry to measure maximal inspiratory pressure and maximal expiratory pressure;respiratory muscle strength was measured using spirometry to measure maximal inspiratory pressure and maximal expiratory pressure	—

Secondary

Measure	Time frame
arterial blood gases;functional capacity in the form of walking test;arterial blood gases was measured using Gas analyzer (Sao2%,PaO2, PaCO2, HCO3, PH). ;functional capacity in the form of six- minute walking test. The test was performed in a 30 ¿ m corridor to walk as fast as possible and patients were allowed to stop if they can not go on . Pulse oximetry was used during test, to stop the walking if their SpO2 dropped 4 % below the resting value or it became less than 90%. ;arterial blood gases was measured using Gas analyzer (Sao2%,PaO2, PaCO2, HCO3, PH). ;functional capacity in the form of six- minute walking test.
