Gender differences were measured in the amount of intramyocellulalr triglyceride (IMCL) and extramyocellular triglyceride (EMCL) in skeletal muscles using ^1H-MR spectroscopy and their relation to body fat amd peak VO_2 was studied. Fourteen apparently healthy subjects were separated into groups by gender. Both the male and female group subjects were selected according to similar ages and BMI (male : n=7, BMI=20.5±0.6 kg/m^2, age=21.1±0.7 years, female : n=7,BMI=20.6±0.5kg/m^2, age=18.7±0.3 years). We found a significant correlation between IMCL and EMCL in the soleus (SOL : p<0.01) and medial gastrocnemius (MG : p<0.01) muscles. IMCL values in SOL were significantly higher than IMCL values in MG and tibialis anterior muscle (TA) in both males and females in the order of SOL>MG>TA (p<0.01). IMCL and EMCL values in MG and SOL among females were significantly higher (p<0.01) than their corresponding values in males. However, a gender difference in IMCL and EMCL values for TA was not found. There was no correlation between IMCL and EMCL values for each muscle and BMI ; but IMCL (r= 0.63 in SOL) and EMCL (r=0.88 and r=0.73 in SOL, and MG, respectively ; p<0.01) values correlated significantly with percent FAT. There was no correlation between IMCL values for each muscle and peak VO_2 ; but the EMCL values of SOL correlated quite negatively with peak VO_2 (r=-0.63, p<0.05). These results suggest that there are gender differences in intramyocellular and extramyocellular triglyceride contents. Lipids were positively related to percent body fat in SOL and MG ; EMCL values may have a negative effect on endurance capacity.
