Effect of Training on Muscle Triacylglycerol and Structural Lipids

We studied whether endurance training impacts insulin sensitivity by affecting the structural and storage lipids in humans. Eight male subjects participated (age 25 +/- 1 years, height 178 +/- 3 cm, weight 76 +/- 4 kg [mean +/- SE]). Single-leg training was performed for 30 min/day for 4 weeks at approximately 70% of single-leg maximal oxygen uptake. After 8, 14, and 30 days, a two-step hyperinsulinemic-euglycemic glucose clamp, combined with...
