Brief Summary:
The deleterious consequences of lung hyperinflation seem not to be restricted to the respiratory system in patients with chronic obstructive pulmonary disease (COPD). Cardiac function, in particular, is strongly influenced by changes in lung volumes and intra-thoracic pressures. In this context, strategies to reduce lung hyperinflation and the work of breathing can positively impact upon cardiac output and blood flow redistribution to peripheral muscles in these patients. There is growing evidence that combination of bronchodilators of different classes is an efficacious and safe strategy for further improving airflow obstruction and hyperinflation in patients with more advanced COPD. Therefore, we aim to investigate that, compared with placebo, a novel LABA/LAMA fixed combination (tiotropium 5 mcg plus olodaterol 5 mcg via Respimat® (Inspiolto®) (TIO/OLO) would decrease lung volumes at rest and during exercise, thereby improving: 1) central and peripheral hemodynamics and 2) arterial oxygenation, with positive consequences on skeletal muscle oxygenation and exercise tolerance in hyperinflated patients with moderate to very severe COPD.

Primary Outcome Measures :
  1. Blood Flow Index (BFI) [ Time Frame: 1 day ]
    Near infrared spectroscopy (NIRS)-derived muscle ICG difference divided by the rise time from 10 to 90% of peak.

Secondary Outcome Measures :
  1. Cardiac output [ Time Frame: 1 day ]
    Cardiac output measured by thoracic cardioimpedance

  2. Muscle oxygenation [ Time Frame: 1 day ]
    Deoxy-hemoglobin (HHb) has been selected as a proxy for muscle fractional O2 extraction and expressed relative to maximum values elicited by cuff-induced ischemia.

  3. Tlim [ Time Frame: 1 day ]
    Exercise tolerance during hugh intensity constant load exercise test (75% of peak workload)

  4. Exercise dyspnea [ Time Frame: 1 day ]
    Borg score rated during isotime and peak exercise

  5. Inspiratory capacity [ Time Frame: 1 day ]
    Inspiratory capacity, inspiratory reserve volume measured at rest, isotime and peak exercise

  6. Inspiratory reserve volume [ Time Frame: 1 day ]
    Inspiratory reserve volume measured at rest, isotime and peak exercise
