Abstract

It has been shown that dietary nitrate (NO3-) is a potential performance enhancer for team-sports athletes. It has been shown to be efficient at reducing the oxygen cost during exercise and is a controlling molecule in circulatory vasodilation.
Purpose: This research was conducted to examine the effects of Dietary NO3- for enhancing the performance of female hockey players during intermittent exercise, designed to include repeated sprints and a hockey specific skill.
Method: Ten university female hockey players (mean age 19.9  1.2yrs) took part in a r double-blind randomised study, receiving NO3- rich beetroot juice (BR: 140ml per day; 8.0 mmol NO3-) and NO3- depleted beetroot juice placebo (PL: 140ml per day; 0.08 mmol NO3-) for 5-days. On the 5th day of supplementation, participants completed the shuttle sprint and dribble test (ShuttleSDT) 2-hrs post ingestion of the supplement.
Results: Peak sprint time was significant for NS compared to PL (z = -2.090, p < 0.05) but no significance was found for peak dribble time. Mean shuttle time and total shuttle time, shown respectively, were found to be significant for both NS sprint and dribble compared to PL (Sprint: z = -2.090, p < 0.05, z = -2.090, p < 0.05; Dribble: z = -2.395, p < 0.05, z = -2.395, p < 0.05).
Conclusions: These findings suggest that dietary NO3- supplementation in the form of beetroot juice facilitates the overall performance of female hockey players in a hockey specific test. Future research should look to use a longer sport specific test closer to the duration of a hockey game or investigate the use of NO3- supplementation as a training intervention. Playing position, training status, menstrual cycle and baseline dietary NO3- intake during supplementation should also be considered.
