to evaluate the effect of inhaled medication together with exercise and activity training on exercise capacity and daily activities in patients with chronic lung disease with obstruction of airways

Conditions: Pulmonary Disease, Chronic Obstructive

Summary: the primary objectives of the study are to explore the effect of treatment with orally inhaled tiotropium + olodaterol fixed dose combination with and without exercise training, and tiotropium comparing to placebo, on top of behavioural modification in improving exercise capacity in patients with copd
