Carnitin palmitoyl transferase 1, CPT1, the rate-limiting enzyme in mitochondrial fatty acid oxidation is decreased in IIM skeletal muscle (A), and correlates with vitamin D levels (B, C). An unpaired t-test (A) and Pearson correlation coefficient (B, C) were used to assess the variables relationships. Points colour scheme: white – HC, light grey—IIM before PT, dark grey – IIM after PT. PT – personal training
