• Pulmonary Function Test (SGaw) Comparison Between QVA149 and Placebo Groups [ Time Frame: day 1 and day 21 ] [ Designated as safety issue: No ]
  The effect of indacaterol and glycopyrronium bromide (QVA149) compared to placebo was measured using the pulmonary function test for Specific Airway Conductance (SGaw) on day 1 and day 21, at 5 min and 15 min post dose as determined by body plethysmography.
• Pulmonary Function Test (FRC) Comparison Between QVA149 and Placebo Groups [ Time Frame: day 1 and day 21 ] [ Designated as safety issue: No ]
  The effect of indacaterol and glycopyrronium bromide (QVA149) compared to placebo was measured using the pulmonary function test for Functional Residual Capacity (FRC) on day 1 and day 21, at 5 min and 15 min post dose as determined by body plethysmography.
• Spirometry After Three Weeks of Treatment on Patients Not Exercising [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  The effect of indacaterol and glycopyrronium bromide (QVA149) compared to placebo was measured using dynamic inspiratory capacity post-dose pre-exercise after three weeks of treatment.
• Exertional Dyspnea Comparison Between QVA149 and Placebo Groups [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]

  The effect of indacaterol and glycopyrronium bromide (QVA149) compared to placebo was measured using exertional dyspnea Borg CR10 Scale® (After 3 weeks of treatment, before, during and after exercise, patients were asked to rate the intensity of their breathing and leg discomfort using the Borg CR10 Scale®). This scale consists of 12-point score that the participants pointed to so as to indicate their level of dyspnea before and during exercise testing (where 0 indicates no breathlessness at all and 12 indicates maximum breathlessness).

  A reduction in this score indicates an improvement.

• Leg Discomfort During Exercise Comparison Between QVA149 and Placebo Groups [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  The effect of indacaterol and glycopyrronium bromide (QVA149) compared to placebo on leg discomfort was measured using Borg CR10 Scale® during sub-maximal constant load cycle ergometry test after three weeks treatment.
• Exercise Endurance Comparison Between QVA149 and Tiotropium Groups [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  Effect of QVA149 110/50 µg o.d. compared with tiotropium 18 µg o.d. in patients with moderate to severe COPD with respect to exercise endurance was measured by a sub-maximal constant load cycle ergometry test ((SMETT)cycle exercise test) after three weeks of treatment.
• Exercise Endurance Time Comparison After a Single Dose of QVA149 Versus Placebo [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  The effect of a single dose of indacaterol and glycopyrronium bromide (QVA149) compared to placebo was measured with respect to exercise endurance time during sub-maximal constant load cycle ergometry test ((SMETT)cycle exercise test).

• The effect of QVA149 compared with placebo on inspiratory capacity (IC) during exercise [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
• To evaluate the effect of QVA149 compared with placebo on exertional dyspnea and leg discomfort during exercise [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  Measured by the Borg CR10 Scale® (dyspnea, leg discomfort)
