  • Quality of life [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Measured by St. George Respiratory Questionnaire
  • Maximal oxygen uptake (VO2-max) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Measurement of spiroergometry

    Measurement of ergometry
  • BODE-index [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    The BODE index is a simple multidimensional grading system for COPD-patients which considers body-mass index, degree of airflow obstruction (FEV1) and dyspnea (BORG scale), and exercise capacity, which will be measured by the six-minute-walk test.

    Body composition/muscle volume will be measured using magnetic resonance imaging.
  • Blood parameters of inflammation [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Inflammatory changes will be assessed via blood test analysis.

    Vascular changes will be assessed via blood test analysis as well as analysis of endothelial function.

    The ten repetition maximum (10-RM) is a measure of the maximal weight a subject can lift 10 times.

    Measured by St. George Respiratory Questionnaire
  • Maximal oxygen uptake (VO2-max) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

    Measured by BORG-scale
  • Body composition [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Body composition will be measured using Dexa-scan.
  • Blood parameters of inflammation [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Inflammatory changes will be assessed via blood test analysis.
  • Vascular changes [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Vascular changes will be assessed via blood test analysis as well as analysis of endothelial function.
  • One repetition maximum [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    The one repetition maximum (1-RM) is a measure of the maximal weight a subject can lift with one repetition.

SCOPE-Study: Salzburg Chronic Obstructive Pulmonary Disease- Exercise and Oxygen Study
The Effect of Supplemental Oxygen During Physical Exercise Training on Exercise Capacity in COPD Patients.

Chronic obstructive pulmonary disease (COPD) is number four of the leading causes of death in the USA and Europe. Moreover, among the top five causes of death, this disease is the only one with increasing mortality rates. Physical training has become an evidence based therapeutic intervention in these patients.

In this study the investigators aim to establish if supplemental oxygen during strength and endurance training improves exercise tolerance. Furthermore, the investigators want to research, if supplemental oxygen has the ability to increase training intensity, which would lead to a greater training effect with respect to respiratory, vascular, inflammatory and anthropometric parameters, as well as quality of life.

SCOPE is a prospective, randomized, double-blinded, controlled, cross-over trial. The investigators aim to enroll 40 patients suffering from COPD aged >30 years. Inclusion criteria are FEV1 30-60%, and PO2 at rest >55 mmHg. At baseline, patients will undergo pre-tests including pulmonary, exercise physiological and medical investigations. Prior to the exercise training, an intervention-free control period with usual care is planned. This will be followed by 2 x 6 weeks with physical training (ergometer based endurance training and strength training, using weight lifting machines) with either supplemental oxygen or usual room air (e.g.: first 6 weeks of exercise with oxygen supplementation followed by 6 weeks of room air). After the initial control period and between these two exercise periods, patients will be tested as described in pre-tests, and at the end of the second exercise training period. In addition, the investigators will assess changes in lung function and symptomatic dyspnoea, as well as in quality of life (St. George's Respiratory Questionnaire).

Within this study, the investigators hope to improve rehabilitation programs for COPD patients.

Chronic Obstructive Pulmonary Disease
  • Other: Physical exercise training with supplemental oxygen

    Prior to the exercise training, an intervention-free control period with usual care is planned.

    Intervention group with oxygen supplementation: Endurance training (performed within 70-80% of the heart rate at the anaerobic threshold) as well as strength training will be performed with oxygen supplementation.

    After 6 weeks of intervention with oxygen supplementation, second intervention period will start with room air instead of oxygen supplementation (as described above).
