We have investigated the skeletal muscle lipid metabolism in upper and lower extremities. Our preliminary measurements of intramyocellular lipids in upper and lower extremities indicate differences in their accumulation which might be due to the different physical activity pattern for the two extremities. The forearms might be less prone to the development of insulin resistance due to greater involvement in daily physical activities.
