Outcomes
Primary outcome [1] 4556 0
To assess disturbance in skeletal muscle mitochondrial function. Biochemical assays will be performed on muscle biopsy samples to analyse mitochondrial enzyme function and protein expression. Also signalling proteins and their gene transcripts will be measured to assess mitochondrial biogenesis.
Timepoint [1] 4556 0
4 weeks
Secondary outcome [1] 7706 0
Markers of mitochondrial biogenesis, including PGC-1 alpha, NFR-1, Tfam and AMPK will be assessed in muscle biopsy samples.

Summary
Brief summary
Th eprimary purpose of this study is the examine the effect of statin medication on skeletal muscle metabolism at rest and during and after acute exercise. We hypothesise that high dose statin ingestion will lead to reductions in mitochondrial function and/or number and thus altering muscle metabolism.
