About this study

Eccentric cycling exercise (ECC) allows training at low metabolic costs and may therefore be valuable for patients with pulmonary vascular disease (PVD). For these patients, regular exercise training has an evidence level 1A recommendation in the current guidelines. Exercise training during longer and regular periods provides chronic adaptation, for which ECC was recently found to have a greater effectiveness than CON by increasing muscle strength, hypertrophy, six-minute walking distance and furthermore, by increasing maximum oxygen uptake (V'O2max) especially in patients with chronic obstructive pulmonary disease (COPD), chronic left heart failure or coronary heart disease.

Furthermore, the investigators conducted an RCT in which the investigators exposed patients with PVD to ECC and concluded that ECC is a feasible and well-tolerated exercise modality for PVD patients with severely lower O2 demand and load to the right ventricle.

Therefore the aim of this project is to investigate whether ECC improves exercise capacity and possibly hemodynamics during prolonged rehabilitation programs in patients with PVD.

Who can participate

Healthy volunteers accepted: No

Treatment and study plan

Rehabilitation with eccentric cycling exercise

Procedure

Instead of normal cycling, patients will exercise on the eccentric bike.

normal rehabilitation

Procedure

Normal rehabilitation will be conducted
