Welcome to Your Daily Hub Summary This review article, published in Frontiers in Nutrition, explores the emerging field of sport nutrigenomics, focusing on how an individual's genetic profile can influence their nutritional requirements and impact athletic performance. It discusses how personalised nutrition moves beyond general dietary guidelines by considering gene-diet interactions for optimising an athlete's health, body composition, and exercise outcomes. While acknowledging the limited...

Welcome to Your Daily Hub Summary This scholarly review explores the efficacy and considerations of sports foods and dietary supplements for track-and-field athletes. It distinguishes between sports foods designed for nutritional goals like hydration and anabolism, and performance supplements such as caffeine, creatine, and nitrates, which have evidence-backed benefits for certain events. The authors stress the importance of a pragmatic approach, recommending that athletes only use products...

Welcome to Your Daily Hub Summary This document presents a research paper from The Journal of Physiology detailing a study on post-exercise recovery strategies for athletes. The authors investigated how co-ingesting whey protein with dual-source carbohydrates (maltodextrin and fructose) affects amino acid availability and glycogen resynthesis in the liver and muscles. The methodology involved well-trained male cyclists undergoing glycogen-depleting exercise, followed by different carbohydrate...

Welcome to Your Daily Hub Summary This paper explores the evolution and effectiveness of personalised nutrition, aiming to address the challenge of making it widely accessible. It discusses how personalised nutrition has moved beyond a gene-centric definition to incorporate dietary, phenotypic, and genotypic information. The concept of metabotyping, which involves grouping individuals based on similar metabolic profiles, is introduced as a novel approach to deliver targeted dietary advice at...

Welcome to Your Daily Hub Summary This original paper, titled “Montmorency cherry supplementation enhances 15 km cycling time trial performance: Optimal timing 90‐min pre‐exercise,” investigates the impact of Montmorency cherry (MC) concentrate on cycling performance. The study, conducted by researchers at the University of Exeter Medical School and other institutions, explored how the timing of supplementation and the training status of cyclists influenced a 15-km time trial. Findings...

Welcome to Your Daily Hub Summary This journal article, published in the Journal of the International Society of Sports Nutrition, presents a research study investigating the effects of beta-alanine supplementation on competitive middle- and long-distance runners aged 15-19. The authors conducted a double-blind, placebo-controlled trial over four weeks to assess changes in aerobic performance, specifically focusing on time to exhaustion (TTE) and aerobic capacity (VO2peak). Their findings...

Welcome to Your Daily Hub Summary This source presents an individual patient data (IPD) meta-analysis exploring the effectiveness of zinc acetate lozenges in treating the common cold. The study specifically focuses on high doses of elemental zinc (over 75mg/day) and re-evaluates data from three previous randomised, placebo-controlled trials using survival analysis, a more appropriate statistical method for time-based outcomes like cold duration. The findings indicate that zinc acetate...

Welcome to Your Daily Hub Summary This text presents a review of existing research on the efficacy of cherry juice in exercise recovery, specifically focusing on Montmorency tart cherries. It discusses the historical context of cherry juice as a recovery aid and critically examines fifteen studies that meet specific inclusion criteria. The review highlights the importance of timing in cherry juice consumption, suggesting that a "precovery" regimen (consuming juice for several days before...

Welcome to Your Daily Hub Summary This source provides an extensive position statement from the International Society of Sports Nutrition, focusing on nutrition and weight cutting strategies for mixed martial arts and other combat sports. It outlines methodologies for reviewing existing literature and offers professional overviews of the bioenergetic demands across various combat disciplines. The text details nutritional recommendations specific to different preparation phases—off-camp, fight...

Welcome to Your Daily Hub Summary This research paper from the Journal of the International Society of Sports Nutrition investigates the impact of protein timing on resistance exercise training (RET) adaptations in older adults. The study specifically examines whether consuming 40 grams of protein post-exercise or pre-sleep enhances muscle thickness and strength compared to RET alone. The findings indicate that neither specific protein timing strategy provided additional benefits in muscle...
