Femoral blood flow in healthy-weight and obese volunteers as assessed by Doppler ultrasound at baseline and in the last 30 min of the fasted and fed clamps

Healthy-weight subjects 
(n = 15)Obese subjects 
(n = 11)
Baseline385 ± 34358 ± 30
Insulin clamp
 Fasted state (insulin 0.6 mU · m−2 · min−1)512 ± 48472 ± 56
 Fed state (insulin 15 mU · m−2 · min−1 plus mixed amino acid infusion [10 g · h−1])529 ± 45450 ± 51
  • Results are expressed as mL · min−1, and values represent the mean ± SEM. A significant main effect of insulin treatment was observed (P < 0.001). No significant main effect of BMI stratification or an interaction between main effects was observed.
