Brief Summary:
Adults with complex congenital heart disease have impaired muscle function compared both to health controls and patients with lesions classified as simple. There is only one study assessing the effects of resistance training in patients palliated with Fontan procedure. The hypotheses of the present study is that home based resistance training will improve muscle function in adults with different complex congenital hear diseases.

Condition or disease Intervention/treatment Phase
Congenital Heart Defect Behavioral: Home based resistance training Not Applicable

Detailed Description:

The number of adults with complex congenital heart disease is increasing and today they outnumber the children with corresponding lesions. However, the longterm prognosis is still unknown and continuously changing as new therapeutic options are introduced.

Patients with complex congenital heart disease have reduced muscle function compared to healthy controls as well as patients with lesions classified as simple. Furthermore, men with congenital heart disease are more commonly underweight and less commonly overweight obese compared to the general population. In addition, men with complex lesions are shorter in comparison to controls. This indicates an altered body composition i.e. muscle mass, fat mass and bone density in this population. Moreover, impaired muscle metabolism has been reported in patients palliated with Fontan procedure.

Adult patients with complex congenital heart disease will be recruited based on defined inclusion and exclusion criteria. Muscle function, muscle strength, muscle metabolism and body composition will be evaluated before randomisation and at follow-up after twelve weeks. The patients will be randomised to twelve weeks of home based resistance training or to a control group. The randomisation ratio will be 1:1 ( intervention:control). The control group will be instructed to continue with their habitual physical activities. The resistance training protocol will be individualised based on the results of the muscle function and muscle strength tests.

The aim of this study is to investigate the effects of resistance training on muscle function, muscle strength, body composition and muscle metabolism in adults with complex congenital heart disease.

Arm Intervention/treatment
Experimental: Resistance training
Home based resistance training 12 weeks home based resistance training 3 times per week, 10-12 reps, 2 sets
Behavioral: Home based resistance training
The participants in the intervention group will receive an individualized resistance training program. The individual adjustments in load will will be made from the results of the muscle function and muscle strength tests. The resistance training will be home based and performed 3 times per week 10-12 reps 2 sets 12 weeks. Increment of load will be performed continuously according to rating of perceived exertion.

No Intervention: Control group
No instructed exercise training. Continue with habitual physical activity.
