Femoral blood flow and vascular conductance (FVC) during calf muscle exercise expressed as an increase from rest to exercise (Δ) in older women and men. The change in Δblood flow and ΔFVC was different between L-citrulline (Cit) and placebo only for exercise at the higher workload in men. Data are mean ± SD. *, difference between pre and post values within condition after controlling for sequence and period effects in a crossover design (P < 0.05).a, no longer significant (P > 0.05) after adjusting for BMI and baseline diastolic pressure in addition to sequence and period effects.
