Ingested beetroot contains inorganic nitrate which is later converted to nitric oxide (NO) in the bloodstream. NO is an important signaling molecule with several physiological functions in the body including acting as a vasodilator, expanding arteries and improving blood flow. Beetroot juice contain inorganic nitrate and consumption of beetroot has been shown to improve skeletal muscle contractility and metabolism enhancing high-intensity exercise performance. Isotonic sports drinks contain carbohydrates and sodium, which also improve exercise performance by providing exogenous glucose for energy to the working muscle and central nervous system and enabling faster absorption of fluid into the bloodstream. The ingestion of exogenous nitrate and isotonic-carbohydrate drink are recognized strategies for promoting exercise performance but whether they can be effectively combined has not been shown. This study will compare the salivary nitrite response, muscle oxygenation and time-trial performance after ingestion of two isotonic drinks with high in nitrate or with no nitrate.
This research study revolves around the physiological outcomes of using post-exercise blood flow restriction (BFR) with high intensity short interval training (ST) The main aims of this study are to compare (i) aerobic performance outcomes, and (ii) anaerobic and muscular performance outcomes - between 2 groups of participants after either undergoing 3 weeks of ST + post-exercise BFR (BFR-ST) or traditional ST.
Bovine colostrum is a dairy food and the first milk produced by the mother cow. Abundant research exists revealing the valuable health benefits it confers due to its unique nutritional properties., including benefits to gastrointestinal health, fitness, and overall well-being.This study aims to test a specific food-grade supplement, ARMRA Colostrum Immune Revival, over a 12-week trial to better understand the well-being, fitness, and gut benefits. This trial will use two groups, one that suffers from gastrointestinal complaints frequently and another that exercises at least three days a week.
The aim of the present study was to evaluate potential beneficial effects of TTFD® EX PLUS (Prince Pharmaceutical Co., Ltd., Yunlin County, Taiwan) on fatigue and ergogenic functions following physiological challenge. The test used a double-blind crossover design and supplementation for 28 days. 32 male and female 20-30 year-old subjects were divided into two groups in a balanced order according to each individual's initial maximal oxygen uptake and were assigned to receive a placebo with equal gender (non TTFD® EX PLUS with same color/day, n=16, 8 male and 8 female) or TTFD® EX PLUS (600mg/tablet/day, n=16, 8 male and 8 female) every morning. After the intervention, there were 28 days of wash-out, during which time the subjects did not receive further interventions.
Energy drinks are widely promoted to increase energy, enhance mental alertness, and improve physical performance. ccording to the National Center for Complementary and Integrative Health (NCCIH) at NIH [1], next to multivitamins, energy drinks are the most popular dietary supplement consumed by American teens and young adults. No two energy drinks are the same, with each using different ingredients. Traditionally, energy drinks contained caffeine, sugar, ginseng and B-vitamins, but newer competitors are bringing different formulations to the market that are also low-calorie/low-sugar and that contain other performance enhancing ingredients, such as beta-alanine and l-citrulline. There are also significant concerns regarding the safety of energy drink consumption. Unfortunately, there are few studies that have (1) examined the effects of energy drink consumption on performance and cardiovascular safety, nor (2) compared these effects among brands with different formulations to examine their safety and efficacy relative to each other and such studies are desperately needed, especially with the growing popularity of energy drinks [3,4].
The RubusElite project is a multi-disciplinary project combining expertise in exercise science, nutrition, biochemistry, microbiology and food science across three institutions: University College Cork, Waterford Institute of Technology and Teagasc Food Research. This project has been funded by the Irish Department for Food, Agriculture and the Marines Food Institutional Research Measure (FIRM) initiative. The overarching aim of the RubusElite project is to provide an attractive, evidence-based performance and recovery food product for those undergoing frequent strenuous exercise in the form of a blackberry enriched, high protein dairy beverage. The process of developing this product will act as an exemplar model, providing best practice guidelines for the development of future functional foods in the performance nutrition space. This randomised controlled trial (RCT) will act as the ultimate test of efficacy of this functional food. It is envisaged that this RCT will assess the impact of a combined protein-polyphenol beverage on post-exercise recovery, exercise capacity, composition of the gut microbiome as well as central stress processing.
Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.
The aim of the clinical trial is to evaluate the efficacy of two novel hydration products on rehydration following exercise.
The purpose of the proposed project is to determine if short-term dietary supplementation of magnesium will improve performance during a series of lab-based exercise tests, will favorably modify the gut-microbiota, and will augment skeletal muscle mitochondrial function.
