Eligibility

Age
18 Years to 64 Years

Inclusion criteria

Inclusion criteria: - Age >= 18 years - m.3243A>G point mutation or single, large scale mtDNA deletion

Exclusion criteria

Exclusion criteria: * insufficient mastery of the Dutch language * pregnancy * severe cardiopulmonary disease (chest pain, heart failure, arrhythmia, pacemaker, cardiac surgery, severe exertional dyspnea, emphysema). If cardiac involvement is present, inclusion will be evaluated by one of the cardiologists with expertise in mitochondrial cardiomyopathy. * coagulopathy (anti-platelet therapy is allowed) * cognitive dysfunction * not able to perform the high intensity training protocol

Design outcomes

Primary

MeasureTime frame
Primary study parameters include mitochondrial and myofibrillar protein synthesis rates of vastus lateralis muscle, calculated from the increase in enriched deuterized alanine in muscle tissue. The trained muscle will be compared with the untrained muscle after 14 days of aerobic exercise.

Secondary

MeasureTime frame
Secondary study parameters are muscle tissue amino acid composition and nitrogen content. Also mitochondrial respiration of muscle tissue from the trained and untrained leg will be compared to baseline tissue using the Oroboros technique.
