Distribution of intramuscular lipids in lower leg muscle of sedentary young female

Abstract

　It is reported that the intramuscular lipids in various health obstacles. However, there are few studies for sedentary young female. The purpose of this study was to clarity the distribution of intramyocellular lipid (IMCL) and extramyocellular lipids (EMCL) in lower leg muscle of sedentary young female. Sixteen female college students (age: 21.0 ± 0.6 years) participated in this study. IMCL and EMCL contents of tibialis anterior (TA), soleus (SOL) and medial gastrocnemius (MG) are evaluated by using proton magnetic resonance spectroscopy (1H-MRS) in this study. Body composition was evaluated by the segmental multifrequency bioelectrical impedance method. IMCL content of SOL was higher than that of TA and MG (p<0.01). EMCL content of SOL and MG was higher than that of TA (SOL vs. TA：p<0.01，MG vs. TA：p<0.01). These results revealed the accumulation of intramuscular lipids in sedentary young female.
