Rehabilitation with eccentric cycling exercise

Clinical Study ID

NCT06480656
EccRehab
  • Ages 18-85
  • All Genders

Study Summary

Eccentric cycling allows high intensities with low metabolic costs. 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

Eligibility Criteria

Inclusion

  • Diagnosed with PVD, either PAH or CTEPH according to recent guidelines

  • Stable medication for at least 1 month

  • No resting hypoxemia (PaO2 >7.3kPa)

Exclusion

Exclusion Criteria:

  • Any co-morbidity that limits the patient to participate the full rehabilitation

  • Enrollments in other trials with active treatments

Study Description

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.
