NCT05454254

Brief Summary

Aim: to evaluate the effect of muscle strengthening exercise training in adults with Fontan circulation compared to healthy controls. Hypothesis: adults with Fontan circulation have a relatively lower effect of muscle strengthening exercise training compared to healthy controls.

Outcome Measures

Primary Outcomes (1)

  • Change in muscle oxygenation kinetics evaluated with near-infrared spectroscopy (NIRS).

    Muscle oxygenation kinetics will be evaluated with near-infrared spectroscopy (NIRS) (PortaLite mini, Artinis medical system BV, Netherlands). With light in the near infrared spectra it is possible to measure oxygenated and deoxygenated haemoglobin within the muscle. the muscle oxygenation kinetics till be evaluated pre, during and post exercise of muscle endurance in shoulder flexion and heel raise.

    10 weeks

Secondary Outcomes (4)

  • Change of isometric muscle strength

    10 weeks

  • Change of muscular endurance

    10 weeks

  • Change of muscle mass

    10 weeks

  • Change of aerobic exercise capacity

    10 weeks

Study Arms (2)

Adults with Fontan circulation

ACTIVE COMPARATOR

Individualised muscle strengthening exercise training protocol.

Other: Individualised muscle strengthening exercise training protocol.

Healthy controls

ACTIVE COMPARATOR

Individualised muscle strengthening exercise training protocol.

Other: Individualised muscle strengthening exercise training protocol.

Interventions

Based on the results of muscle function tests at baseline an individualised exercise protocol will be designed.

Adults with Fontan circulationHealthy controls

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age minimum 18 years
  • Patients: Congenital heart disease (Fontan circulation, univentricle heart)
  • Controls: no known congenital heart disease.

You may not qualify if:

  • Muscle strenghtening exercise training at regular basis (2 times/week or more)
  • Active disease or other condition that affect exercise training (e.g. rheumatoid arthritis)
  • Cognitive or psychological affection
  • Other conditions that affect independent decision-making competence
