Dietary Nitrate Supplementation And Exercise Performance
Dietary nitrate is growing in popularity as a sports nutrition supplement.
Dietary nitrate supplementation and exercise performance. Recognizing the importance of evaluating the influence of dietary nitrate supplementation on exercise performance lansley et al. Over the last decade there has been a growing interest in the utility of nitrate no3 supplementation to improve exercise related performance after consumption dietary no3 can be reduced to nitric oxide a free radical gas involved in numerous physiological actions including blood vessel vasodilation mitochondrial respiration and skeletal muscle contractile function. Methods we performed a double blind placebo controlled cross over single dose study. This article reviews the evidence base for the potential of inorganic nitrate to enhance sports and exercise performance.
Inorganic nitrate is present in numerous foodstuffs and is abundant in green leafy vegetables and beetroot. Following ingestion nitrate is converted in the body to nitrite and stored and circulated. We investigated the hypotheses that acute nitrate dosing would improve exercise performance and reduce the oxygen cost of submaximal exercise in people with copd. Dietary nitrate supplementation can enhance exercise performance in healthy people but it is not clear if it is beneficial in copd.
Studies were included if a placebo versus dietary nitrate only supplementation protocol was able to be compared and if a quantifiable measure of exercise performance was 30 s for a single bout of exercise or the combined total for multiple bouts. Recent studies indicate that dietary nitrate supplementation administered most commonly in the form of beetroot juice can a improve muscle efficiency by reducing the o 2 cost of submaximal exercise and thereby improve endurance exercise performance and b enhance skeletal muscle contractile function and thereby improve muscle power and. This article reviews the evidence base for the potential of inorganic nitrate to enhance sports and exercise performance. Asked nine club level male cyclists mean 56 ml kg per minute to complete both a 4 km and a 16 1 km time trial on a cycle ergometer following the acute consumption of 0 5 l of beetroot juice 6 2 mmol of nitrate.
We investigated the hypotheses that acute nitrate dosing would improve exercise performance and reduce the oxygen cost of submaximal exercise in people with copd.
