Supplementary files for article "Greater hepatic lipid saturation is associated with impaired glycaemic regulation in men with MASLD but is not altered by six weeks of exercise training"Aims To examine the impact of impaired glycaemic regulation and exercise training on hepatic lipid composition in men with metabolic dysfunction-associated steatotic liver disease (MASLD).Materials and methods In Part A (cross-sectional design), 40 men with MASLD (liver proton density fat fraction [PDFF]≥5.56%) were recruited to one-of-two groups: 1) normal glycaemic regulation (NGR; HbA1cResults In Part A, hepatic SI was higher and hepatic UI was lower in the IGR vs. NGR group (P=0.038), and this hepatic lipid profile was associated with higher HbA1c, FPG, HOMA-IR and plasma CK18 M65 (rs≥0.320). In Part B, hepatic lipid composition and liver PDFF were unchanged after EX vs. CON (P≥0.257), while FPG was reduced and V̇O2 peak was increased (P≤0.030). ΔV̇O2 peak was inversely associated with Δhepatic SI (r=-0.433) and positively associated with Δhepatic UI and Δhepatic PUI (r≥0.433).Conclusions IGR in MASLD is characterised by greater hepatic lipid saturation, however, this composition is not altered by six-weeks of moderate-intensity exercise training.
