Brief summary:
This study investigated the effect of exercise and high-dose salbutamol on the maximum heart rate in patients with chronic obstructive pulmonary disease (COPD) receiving therapeutic doses of indacaterol, salmeterol and placebo.

Detailed description:

Arms:
arm 1: Part 1: Sequence 'A' consisted of - Period 1, patient received a single inhaled dose of indacaterol 300μg capsule via the Concept1 inhaler device. Period 2, patient received single dose of salmeterol 50μg via Diskus dry powder inhaler (DPI). Period 3, patient received single dose of indacaterol matching placebo via the Concept1 inhaler device.

Part 2: Sequence 'A' consisted of - Period 1, patients received a morning single inhalational dose of indacaterol 300μg and an evening single inhalation dose of indacaterol matching placebo via the Concept1 inhaler device. Period 2, patients received morning and evening single inhalational dose of salmeterol 50μg via Diskus DPI. Period 3, patients received single inhalation dose of indacaterol matching placebo in morning and evening via Concept1 device.
