A comparison of citrulline and arginine for increasing exercise-induced vasodilation and blood flow
نویسندگان
چکیده
Background One goal of supplementation has been to increase blood flow to skeletal muscle during exercise. Raw L-citrulline (RC) and raw L-arginine (RA) has often been used for its vasodilatory effects, and recently, citrulline and arginine have been bound to a whey peptide (CP and AP, respectively) to increase bioavailability. The purpose of the present study was to compare the acute hemodynamic effects of RC, CP, RA, and AP following resistance exercise in healthy, men when administered at a common, commercial dose.

A comparison of raw citrulline and citrulline peptide for increasing exercise-induced vasodilation and blood flow
Background One goal of supplementation has been to increase blood flow to skeletal muscle during exercise. Raw L-citrulline (RC) has often been used for its vasodilatory effects, and recently, RC has been bound to a whey peptide (CP) to increase bioavailability.

متن کاملIntracellular Mechanistic Role of Nitric Oxide : A Comparative Analysis of the Ef - fectiveness of L - Arginine and L - Citrulline Supplementation on Nitric Oxide Syn - thesis and Subsequent Exercise Performance in Humans
Of late, there has been a major increase in the marketing of sport nutraceuticals claiming to augment exercise performance and recovery due to their ability to increase nitric oxide (NO) release. NO is a labile molecule that is known to play a major role in regulating vasodilation, blood flow, platelet adhesion, immune system function, and mitochondrial respiration. Endogenous NO synthesis is c...
متن کاملContribution of endothelium-derived nitric oxide to exercise-induced vasodilation.
BACKGROUND Endothelium-derived nitric oxide is an important modulator of resting vascular tone in animals and humans. However, the contribution of nitric oxide to exercise-induced vasodilation is unknown. METHODS AND RESULTS The effect of NG-monomethyl-L-arginine (L-NMMA), an inhibitor of nitric oxide synthesis, on exercise-induced vasodilation was studied in 18 healthy subjects (mean +/- SD,...
متن کاملComparison of Watermelon and Carbohydrate Beverage on Exercise-Induced Alterations in Systemic Inflammation, Immune Dysfunction, and Plasma Antioxidant Capacity
Consuming carbohydrate- and antioxidant-rich fruits during exercise as a means of supporting and enhancing both performance and health is of interest to endurance athletes. Watermelon (WM) contains carbohydrate, lycopene, l-citrulline, and l-arginine. WM may support exercise performance, augment antioxidant capacity, and act as a countermeasure to exercise-induced inflammation and innate immune...
متن کاملAcute hemodynamic effects of L-arginine, arginine nitrate, and arginine peptide on exercise-induced vasodilation and blood flow in healthy men
Background Increasing blood flow to skeletal muscle during exercise may benefit both recreational and elite athletes. Raw arginine (RA) is a commonly used supplement for increasing blood flow via nitric oxide production. Arginine has been also been bound to a whey peptide (AP) and to nitrate (AN) to increase bioavailability. The purpose of the present study was to determine the acute hemodynami...
