(1) Background: Participation in ultra-endurance sports, particularly ultra-running, has increased over the previous three decades. These are accompanied by high energetic demands, which may be further exacerbated by extreme environmental conditions. Preparation is long-term, comprising of sufficient exercise management, supportive dietary habits, and nutritional intakes for optimal adaptations. Gastrointestinal symptoms are often cited as causing underperformance and incompletion of events. Though the majority do not pose serious long-term health risks, they may still arise. It has been suggested that the nutritional interventions employed by such athletes prior to, during, and after exercise have the potential to alter symptom incidence, severity, and duration. A summary of such interventions does not yet exist, making it difficult for relevant personnel to develop recommendations that simultaneously improve athletic performance by attenuating gastrointestinal symptoms. The aim of this research is to systematically review the literature investigating the effects of a nutrition intervention on ultra-endurance athletes exercise-induced gastrointestinal symptom incidence, severity, or duration. (2) Methods: A systematic review of the literature was conducted (PubMed, CINAHL, Web of Science, and Sports Discus) in January 2023 to investigate the effects of various nutrition interventions on ultra-endurance athletes’ (regardless of irritable bowel syndrome diagnosis) exercise-induced gastrointestinal symptoms. Variations of key words such as “ultra-endurance”, “gastrointestinal”, and “nutrition” were searched. The risk of bias in each paper was assessed using the ADA quality criteria checklist. (3) Results: Of the seven eligible studies, one was a single field-based case study, while the majority employed a crossover intervention design. A total of n = 105 participants (n = 50 male; n = 55 female) were included in this review. Practicing a diet low in short-chain, poorly absorbed carbohydrates, known as fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs), as well as employing repetitive gut challenges of carbohydrates, remain the most promising of strategies for exercise-induced gastrointestinal symptom management. (4) Conclusion: Avoiding high-FODMAP foods and practicing repetitive gut challenges are promising methods to manage gastrointestinal symptoms. However, sample sizes are often small and lack supportive power calculations.

Mild traumatic brain injury (mTBI) represents a significant burden for individuals, economies, and healthcare systems worldwide. Recovery protocols focus on medication and physiotherapy-based interventions. Animal studies have shown that antioxidants, branched-chain amino acids and omega-3 fatty acids may improve neurophysiological outcomes after TBI. However, there appears to be a paucity of nutritional interventions in humans with chronic (≥1 month) symptomology post-mTBI. This systematic literature review aimed to consolidate evidence for nutrition and dietary-related interventions in humans with chronic mTBI. The review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021277780) and conducted following the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three reviewers searched five databases (PubMed/MEDLINE, Web of Science, SPORTDiscus, CINAHL Complete and Cochrane), which yielded 6164 studies. Nine studies met the inclusion criteria. The main finding was the lack of interventions conducted to date, and a quality assessment of the included studies was found to be fair to good. Due to heterogeneity, a meta-analysis was not feasible. The six nutrition areas identified (omega-3 fatty acids, melatonin, Enzogenol®, MLC901, ketogenic diet and phytocannabinoids) were safe and well-tolerated. It was found that these nutritional interventions may improve cognitive failures, sleep disturbances, anxiety, physical disability, systolic blood pressure volume and sport concussion assessment tool scores following mTBI. Potential areas of improvement identified for future studies included blinding, reporting compliance, and controlling for confounders. In conclusion, further research of higher quality is needed to investigate the role of nutrition in recovery from mTBI to reduce the burden of chronic outcomes following mTBI.

Sports-related concussion (SRC) is an injury whereby impact to the face/head/neck impairs cognitive functioning. Parasport athletes have an increased risk for SRC. The Previous Concussion in Sport Group iterations lack guidance for parasport SRC assessment, management, and return-to-play. This article aims to investigate the research relating to parasport SRCs published since the 2021 Concussion in Para Sport (CIPS) position statement and highlights possible new recommendations. A literature review of parasport concussions was conducted. Articles citing the 2021 publication and/or published since then were reviewed. Relevant data were extracted and discussed in this article. Since 2021, twelve (n = 12) articles emerged investigating parasport SRC. Parasport athletes experience greater concussion symptoms and severity scores compared to able-bodied athletes. Visually impaired athletes account for >50% of parasport SRCs. Wheelchair basketball and rugby have the highest SRC incidence rates across parasports. Current SRC assessment methodologies are not designed with consideration of parasport athletes’ unique experiences. Guidelines lack a return-to-learning protocol, making returning to education/work challenging for such athletes. Understanding these athletes’ SRC experiences is paramount in supporting their recovery. Specific guidelines for SRC assessment, management, return-to-play, and return-to-learn for parasport athletes are necessary to enhance their rehabilitation and avoid the occurrence of long-term symptoms.

Introduction: Agri-food systems in Europe are predominantly male-dominated. Female food entrepreneurs can play a key role in the development of novel, sustainable food products. The aim of the present study was to gain an increased understanding of the various barriers which female agri-food entrepreneurs situated in rural areas perceive as hindrances to their entrepreneurial growth and development. Methodology: A total of five separate focus groups (n = 29 participants; 18 females) were carried out with agri-food entrepreneurs throughout Europe (Ireland, Belgium, Poland, Italy). The discussions were semi-structured and revolved around individuals’ perceptions of the support received from their surrounding infrastructure and their opinions on mentorship programmes. A reflective thematic analysis was conducted following verbatim transcription of the conversations from the focus groups. Findings: Three major themes were identified: 1. Business Initiation and Development, 2. Perceived Barriers, and 3. Mentorship Programmes. Of these central themes, each of these themes was further divided into accompanying sub-themes. The most often-cited theme was the lack of adequate financial support and experiencing frustration with the complexity of funding application administrative processes. Socio-cultural support was oftentimes lacking, with participants noting they often felt more senior, experienced entrepreneurs gatekept information to avoid their development and expansion. Females in particular experienced gender-discriminatory behaviour from peers and those more senior than themselves. Finally, the vast majority of participants were aware of the benefits of an online presence but lacked confidence in their digital abilities and were unsure where to source the relevant support. Conclusions: These findings highlight a range of issues that need to be addressed to improve the infrastructure surrounding agri-food entrepreneurs throughout Europe and sustain the food sector. This knowledge may be used to guide policymakers and those at decision-making levels.

Ultra-endurance running (UER) events are defined based upon duration, exceeding 4-6 hours, or distance, surpassing the 26.3-mile marathon (1). Of | POSTER
