Abstract

SUMMARY: INCREASING BLOOD FLOW TO WORKING MUSCLES, THROUGH INCREASED VASODILATATION, HAS THE POTENTIAL TO INCREASE WORK CAPACITY DURING BOTH AEROBIC AND ANAEROBIC PERFORMANCES AND POSSIBLY ENHANCE RECOVERY THROUGH INCREASED NUTRIENT DELIVERY. BECAUSE OF THESE POTENTIAL BENEFITS, L-ARGININE SUPPLEMENTS HAVE BECOME EXTREMELY POPULAR OVER THE PAST DECADE BASED ON THEIR POTENTIAL NITRIC OXIDE–STIMULATING ABILITY, ALTHOUGH THE RESEARCH DOES NOT APPEAR TO SUPPORT THE INGESTION OF L-ARGININE TO INCREASE VASODILATATION. IN CONTRAST, CONSUMPTION OF FOODS HIGH IN NITRATE CONCENTRATION, SUCH AS BEETROOT JUICE, HAS BEEN SHOWN TO INCREASE PLASMA NITRATES, PREFERENTIALLY ALTERING HEMODYNAMICS AND POSSIBLY ENHANCING ACUTE EXERCISE PERFORMANCE.
