The Effect of Dietary Nitrate Supplementation on Linear Running Sprint Performance, Agility and Vertical Jump Performance in a Rested and Fatigued State
June 20, 2018 updated by: PepsiCo Global R&D
Dietary nitrate (NO3-) supplementation has been shown to improve skeletal muscle contractility and fatigue resistance, particularly in fast-twitch (type II) muscle fibers.
Furthermore, NO3- supplementation has been shown to speed reaction time.
Taken together, these findings suggest that NO3- ingestion may be ergogenic during all-out sprint running and reactive agility tasks.
Moreover, increasing muscle force production at high contraction speeds would be expected to translate into improved muscle power and, subsequently, improved performance in very explosive forms of exercise, such as vertical jumping.
Therefore, the purpose of this investigation is to assess the effect of short term (5 days) NO3- supplementation on linear running sprint performance, reactive agility and vertical jump performance in a rested and fatigued state.
