the pioneering work of scientists such as A. V. Hill ([7][1]) and August Krogh ([10][2]), investigating the dynamics of O2 uptake during exercise, challenged our understanding of bioenergetics and energy homeostasis. Applied physiologists continue to advance our knowledge of altered energy transfer

Nitrate Ingestion: Implications for Performance and Training
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…
The effects of dietary nitrate (beetroot juice) supplementation on exercise performance: A review
TLDR
The most prominent and consistent effects of dietary nitrate supplementation is a reduction in the oxygen cost of exercise and an increase in exhaustion time at submaximal workloads.
The Effect of Beetroot Juice on Repeated Sprint Performance and Muscle Force Production
TLDR
In this study 14 male team-sport players were assigned in a double blind, randomized, crossover design performing 30 hours before the completion of a Yo-yo intermittent recovery level 1 test and concluded that the same supplements enhance muscle contractile efficiency during knee-extensor exercise.
Influence of acute dietary nitrate supplementation on 50 mile time trial performance in well-trained cyclists
Dietary nitrate supplementation has been reported to improve short distance time trial (TT) performance by 1–3 % in club-level cyclists. It is not known if these ergogenic effects persist in longer…
Dietary nitrate increases tetanic [Ca2+]i and contractile force in mouse fast‐twitch muscle
TLDR
These results provide a new mechanism by which nitrate exerts beneficial effects on muscle function with applications to sports performance and a potential therapeutic role in conditions with muscle weakness.
A–Z of nutritional supplements: dietary supplements, sports nutrition foods and ergogenic aids for health and performance—Part 27
TLDR
In his brief review for Part 27, Professor Andy Jones describes the link between supplementing the diet with nitrate-rich beetroot juice to enhance NO availability and the consequential proposed mechanisms that could lead to an improvement in exercise performance.
The role of cherries in exercise and health
TLDR
This review critically evaluates and discusses the use of cherries as a supplementation strategy to enhance recovery of muscle function, inhibit exercise‐induced inflammation, oxidative stress, and pain primarily; furthermore, the potential application of cherry products to clinical populations is discussed.
Effect of Dietary Nitrate on Force Production and Sarcoplasmic Reticulum Ca 2+ Handling in Rat Fast-Twitch Muscles Following Eccentric Contraction
TLDR
Results indicate that dietary nitrate supplementation can alleviate ECC-related decreases in force production mediated through inhibited reductions in the SR Ca2+ release function.
Beetroot juice supplementation for the prevention of cold symptoms associated with stress: A proof-of-concept study
Montmorency Cherries Reduce the Oxidative Stress and Inflammatory Responses to Repeated Days High-Intensity Stochastic Cycling
TLDR
The attenuated oxidative andinflammatory responses suggest Montmorency tart cherry concentrate may be efficacious in combating post-exercise oxidative and inflammatory cascades that can contribute to cellular disruption.

Dietary nitrate supplementation reduces the O2 cost of walking and running: a placebo-controlled study.
TLDR
The results indicate that the positive effects of 6 days of BR supplementation on the physiological responses to exercise can be ascribed to the high NO(3)(-) content per se.
Effects of dietary nitrate on oxygen cost during exercise
TLDR
This study investigated if dietary nitrate had any effect on metabolic and circulatory parameters during exercise and found that it did not.
Dietary nitrate supplementation enhances muscle contractile efficiency during knee-extensor exercise in humans.
TLDR
The reduced O(2) cost of exercise following dietary NO(3)(-) supplementation appears to be due to a reduced ATP cost of muscle force production.
Dietary nitrate supplementation reduces the O2 cost of low-intensity exercise and enhances tolerance to high-intensity exercise in humans.
TLDR
The reduced O2 cost of exercise following increased dietary nitrate intake has important implications for the understanding of the factors that regulate mitochondrial respiration and muscle contractile energetics in humans.
Acute and chronic effects of dietary nitrate supplementation on blood pressure and the physiological responses to moderate-intensity and incremental exercise.
TLDR
It is indicated that dietary NO(3)(-) supplementation acutely reduces BP and the O(2) cost of submaximal exercise and that these effects are maintained for at least 15 days if supplementation is continued.
Phosphocreatine hydrolysis during submaximal exercise: the effect of FIO2.
TLDR
The results demonstrate that the differences in phosphocreatine concentration with varied FIO2 are not the result of different V(O2) onset kinetics, as this was eliminated by the experimental design, and demonstrate that changes in intracellular oxygenation result in significant changes in cell homeostasis.
Effects of altered nitric oxide availability on rat muscle microvascular oxygenation during contractions.
TLDR
It is suggested that P(O2)mv derangements in ageing and chronic disease conditions may potentially result from impairments in NO availability and suggests that the role of nitric oxide in controlling microvascular O2 pressure at rest and during contractions is explored.
Roles of dietary inorganic nitrate in cardiovascular health and disease.
TLDR
A theory is now emerging suggesting nitrate as an active component in vegetables contributing to the beneficial health effects of this food group, including protection against cardiovascular disease and type-2 diabetes.
Influence of hyperoxia on muscle metabolic responses and the power–duration relationship during severe‐intensity exercise in humans: a 31P magnetic resonance spectroscopy study
TLDR
Data indicate that Tlim during severe‐intensity exercise is associated with the attainment of consistently low values of muscle [PCr] and pH, and the CP and W′ parameters of the power–duration relationship were both sensitive to the inspiration of hyperoxic gas.

TLDR
Research published over the past few years makes it clear that skeletal muscle produces NO and that endogenous NO modulates muscle function, and much remains to be learned about the physiological importance of NO actions and about their underlying mechanisms.
