About this trial

Investigate the effects of exercise training on the cardiopulmonary function and exercise capacity in COPD patients.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

COPD classified as levels 2-4.

Stable condition without worsening in the past three months.

No participation in any rehabilitation program within the past six months.

Ability to understand and follow verbal commands and cooperate with an exercise training program.

Disqualifiers

Unconscious or unable to cooperate with the evaluator.

Hospitalization due to acute illness within the past three months.

Severe joint diseases or history of lower limb surgery.

Severe cardiovascular disease (e.g., presence of a cardiac pacemaker or acute myocardial infarction within the past six months).

Trial design

Design model

Parallel

Treatments tested in this trial

  • Aerobic exercise intervention

    Behavioral

    The aerobic exercise intervention will utilize an ergometer. The program will be conducted 2-3 times per week over a 3-month period.

  • Disease and exercise suggestion

    Behavioral

    The participants will be provided by educational program about COPD self-care and home-based exercise approach.

  • Blood flow restriction (BFR) intervention

    Behavioral

    Blood flow restriction (BFR) intervention will combine aerobic exercise on the ergometer with BFR training. The program will be conducted 2-3 times per week over a 3-month period.

Treatment groups

90 Participants
are divided into 3 treatment groups
Group A: Usual care groupActive comparator 1 intervention
Group B: Aerobic exercise group-cyclingExperimental treatment 1 intervention
Group C: BFR group-cycling + BFRExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Oxygen consumption (VO2)

Oxygen consumption examined by cardiopulmonary exercise test

Time frame
Change from baseline (0 week) to follow up (20 weeks)
2

Diaphragm capacity

Diaphragm capacity examined by diaphragmatic ultrasound

Time frame
Change from baseline (0 week) to follow up (20 weeks)

Secondary outcomes

1

Functional capacity

Functional capacity examined by 6MWT

Time frame
Change from baseline (0 week) to follow up (20 weeks)
2

Heart Rate Variability

Heart Rate Variability examined by autonomic nervous system

Time frame
Change from baseline (0 week) to follow up (20 weeks)
3

Pulmonary function test

Pulmonary function test examined by spirometer. Spirometry is a physiological test that measures the ability to inhale and exhale air over time. The main spirometry results are forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and the FEV1/FVC ratio.

Time frame
Change from baseline (0 week) to follow up (20 weeks)
4

Maximum respiratory pressure

Maximum respiratory pressure examined by pressure meter

Time frame
Change from baseline (0 week) to follow up (20 weeks)
