Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food supplements for athletes and bodybuilders often refer to the vasodilatory effects of nitric oxide (NO) without providing detailed explanations, and there is a lack of understanding about the effects of administering exogenous NO on exercise performance, particularly in healthy humans.
Innovation Solution
Administering inorganic nitrate (NO3−) prior to exercise to increase exercise endurance by delaying fatigue, reducing oxygen consumption, and increasing available energy to muscles, with the composition potentially including polyphenols and non-pathogenic live bacteria for enhanced bioavailability and bioactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inorganic nitrate is administered to increase exercise endurance and reduce oxygen consumption, then exercise performance is improved, but there is a risk of causing hypotension and methemoglobinemia
Solution Approach 1:
The patent applies parameter changes by carefully controlling the dosage of inorganic nitrate administered. By optimizing the concentration and amount of nitrate in the composition, the patent achieves improved exercise endurance while maintaining safety parameters that prevent hypotension and methemoglobinemia. This involves adjusting dosing regimens and nitrate concentrations to fall within therapeutic windows that maximize performance benefits while minimizing adverse effects.
Solution Approach 2:
The patent uses polyphenols and non-pathogenic live bacteria as intermediaries to enhance the bioavailability and bioactivity of inorganic nitrate. These components facilitate the conversion of nitrate to nitrite and subsequently to nitric oxide, improving the efficacy of nitrate supplementation while allowing for lower doses that reduce the risk of hypotension and methemoglobinemia.
2Use of energy by moving object
If inorganic nitrate is administered to reduce oxygen consumption during exercise, then energy efficiency is improved, but the mechanism of action is not fully understood
Solution Approach 1:
The patent administers inorganic nitrate prior to exercise to establish adequate tissue levels of nitrate and its conversion products before physical activity begins. This preliminary supplementation ensures that the nitrate-nitrite-nitric oxide pathway is activated and optimized before exercise demands increase, allowing for reduced oxygen consumption during the actual exercise performance.
Solution Approach 2:
The patent incorporates polyphenols and non-pathogenic live bacteria as intermediary substances that enhance nitrate bioconversion. These intermediaries facilitate the conversion of ingested nitrate to nitrite in the oral cavity and gut, and subsequently to nitric oxide in tissues, thereby improving the understanding and utilization of the nitrate pathway for reducing oxygen consumption during exercise.
3Reliability
If compositions include polyphenols and non-pathogenic live bacteria for enhanced bioavailability, then nitrate efficacy is improved, but composition complexity increases
Solution Approach 1:
The patent merges inorganic nitrate with polyphenols and non-pathogenic live bacteria into a single integrated composition. This combination leverages the synergistic effects where polyphenols act as antioxidants and nitrate reducers, while non-pathogenic bacteria facilitate nitrate conversion to nitrite. The merged formulation enhances overall nitrate bioavailability and efficacy while presenting a unified product that simplifies administration despite the multiple active components.
Solution Approach 2:
The patent creates a composite nutritional composition containing inorganic nitrate, polyphenols, and non-pathogenic live bacteria. This composite formulation combines multiple functional ingredients that work together to enhance nitrate bioavailability, improve exercise performance, and support health benefits. The composite structure allows for controlled release and interaction of components, optimizing the overall effect while managing formulation complexity through integrated design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The administration of inorganic nitrate reduces oxygen consumption and increases muscular efficiency during exercise without causing significant hypotension or methemoglobinemia, leading to improved exercise performance and glucose homeostasis.
Implementation Method 1
Dietary nitrate (found mainly in green leafy vegetables) is absorbed from the circulation by the salivary glands, secreted in saliva and partly converted to nitrite in the oral cavity by nitrate reducing bacteria.
Implementation Method 2
Further reduction of nitrite into bioactive NO can occur spontaneously in acidic or reducing environments but is also greatly enhanced by various proteins and enzymes including deoxyhemoglobin in blood
Implementation Method 3
deoxyhemoglobin in blood, deoxymyoglobin, xanthine oxidase and possibly by enzymes of the mitochondrial respiratory chain
Implementation Method 4
NO is involved in control of cellular respiration through interaction with enzymes of the mitochondrial respiratory chain

AI summary
Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.
