Title: Aerobic Training in Patients With Congenital Myopathies
Brief Summary: Congenital myopathies are clinical and genetic heterogeneous disorders characterized by skeletal muscle weakness. Most patients experience muscle weakness and fatigue throughout their life. However, progression of symptoms is rare. There are no specific treatments for congenital myopathies. Training has been shown to benefit several other muscle diseases with weakness, but the defect in congenital myopathies involves contractile proteins of the sarcomere, why the effect of training is uncertain in these conditions. The investigators will therefore investigate the effect cycle-ergometer training for 30 minutes, three times weakly, for ten weeks in 15 patients with congenital myopathy. Another 5-10 congenital myopathy patients, who do not train, will serve as controls for the trained patients. The study starts and ends with a test day, where efficacy based on VO2max, performance in functional tests and a questionnaire will be assessed.


Options:
A: Inclusion Criteria:

* Physically inactive
* Stable drugs regime for at least three months

Exclusion Criteria:

* Other rheumatic diseases
* Physical disability that prevent the patient to perform the physical tests
* Severe pulmonary disease
B: Inclusion Criteria:

* Able to provide informed consent
* Genetically proven DM1
* Suffering from severe fatigue (CIS fatigue \>35
* Able to walk independently

Exclusion Criteria:

* Neurological or orthopaedic co-morbidity interfering with the interventions or possibly influencing outcomes.
* Use of psychotropic drugs (except Modafinil, Ritalin and antidepressants where the dosing regimen has been stable for at least 12 months prior to screening). If the doses of Modafinil or Ritalin increase during the 10 months of the intervention then the participant will be excluded.
* Severe depression as screening (judged as meeting DSM-IV criteria for a depressive episode).
* Participation in another clinical trial of an investigational medicinal product (CTIMP) or other interventional study considered to influence outcomes being evaluated in OPTIMISTIC.
* Unable to complete study questionnaires.
* Subject participating in another clinical trial (other than observational trials and registries) concurrently or within 30 days prior to screening for entry into this study.
C: Inclusion Criteria:

* Danish patients with gene verified congenital myopathy

Exclusion Criteria:

* Patients who are to week to train at a cycle-ergometer for 10 weeks
* Patients who have other health issues, which can disturb the interpretation of the efficacy
D: Inclusion Criteria:

* Patients with chronic, stable polymyositis or dermatomyositis with diagnosis of definite or probable polymyositis or dermatomyositis (Bohan and Peter 1975)
* Age 18-80 years
* Duration since diagnosis \> 6 months
* Exercising \< once a week,
* Stable disease activity and medication for at least one month.

Ten healthy controls matched for age, gender and physical exercise level will be included.
