In this study, 9 obese male participants underwent 6 weeks of sprint interval training (SIT) and changes in visceral, subcutaneous and intra-hepatocellular fat were measured using MRI and MRS at baseline, control (>4 weeks later) and post exercise. Change in liver lipid composition was also assessed.
