Proton magnetic resonance spectroscopy (MRS) was used to study lipid storage in the thigh muscles of elderly, obese women before and after a diet or exercise four-month intervention program. Subjects were divided in two groups, a diet group who lost 10% in body weight or a weight stable exercise group. The exercise group showed significant changes in EMCL and total lipid concentrations, with no change in IMCL concentration. The diet group showed no significant changes in lipid storage with intervention.
