- Primary Outcome Measures
Name Time Method <p>The main study outcome paramters are:<br /><br><br /><br>1.the energy generating capacity of muscle mitochondria,<br /><br>2. muscle function (muscle strength, muscle contraction efficiency,muscle<br /><br>fatigability),<br /><br>3. maximal aerobic capacity<br /><br><br /><br>These parameters shall be compared between the three study groups</p><br>
- Secondary Outcome Measures
Name Time Method <p>1. Mitochondrial number (in muscle biopsy),<br /><br>2. Blood paramters: Lipid profile (Total cholesterol, HDL-, LDL-cholesterol,<br /><br>triglycerides), liver enzymes (ASAT, ALAT, gamma-GT), creatine kinase,<br /><br>pyruvate, lactate<br /><br>3. statin concentrations in muscle and blood<br /><br>4. Questionnaires on muscle complaints (Short-form McGill pain questionnaire<br /><br>and Short-form Brief Pain Inventory)</p><br>
