Seven days of aerobic exercise training improves conduit artery blood flow following glucose ingestion in patients with type 2 diabetes

11 overweight or obese (BMI 33.7 ± 1.4 kg/m²), sedentary (VO2peak 22.5 ± 1.4 ml·kg⁻¹·min⁻¹) adults (mean age 53 ± 2 yr, 6 men/5 women) with non-insulin-dependent type 2 diabetes (HbA1c 6.63 ± 0.18%).

7 days of supervised aerobic exercise training (20 min treadmill walking, 20 min stationary cycling, 20 min treadmill walking; 60 min/day at 60-75% heart rate reserve).

Baseline measurements in the same individuals prior to the exercise intervention (before-and-after design).

Femoral blood flow (FBF) measured by Doppler ultrasound during an oral glucose tolerance test (OGTT; 75 g glucose).surrogate
