INTRAMUSCULAR LIPID CONTENT IN FEMALE ENDURANCE-TRAINED ELDERLY PERSONS BY IN VIVO 1H-MR SPECTROSCPY

The aim of this study is the evaluation of intramyocellular (IMCL) and extramyocellular lipids (EMCL) in skeletal muscle in elderly female endurance-trained individuals. The subjects comprised endurance-trained elderly persons (END : n=7, age=66.1±2.0) and healthy elderly control subjects (CON : n=7, age=70.1±3.0). All subjects were female and matched by age and lower BMI. We quantified differences in IMCL and EMCL concentrations in the tibialis anterior (TA), soleus (SOL), and medial gastrocnemius (MG) muscles using 1H-MR spectroscopy. The IMCL and EMCL contents in SOL and MG in END were significantly lower than those in CON (p
