Background
Previous studies have indicated that ingestion of nitric oxide (NO) supplements prior to exercise may potentially enhance anaerobic performance. Collectively, NO products are marketed to increase energy, strength, stamina and endurance during anaerobic exercise. However, delivery modes and formula combinations of NO supplements differ in regards to other nutrients included (i.e., creatine, caffeine, etc.) that could possibly impact the efficacy of NO product claims. The purpose of this pilot study was to compare the effects of two NO supplement formulations (NO1 & NO2) on indices of anaerobic power.
