Special Issue Information

Dear Colleagues,

Evidence from various preclinical and clinical studies has revealed that various dietary components (e.g., nutrients, phytochemicals, prebiotics/probiotics, etc.) play a significant role in exercise performance and have emerged as potential ergogenic agents in a broad range of exercise scenarios and models.

Even well-established supplements such as nutritional ergogenic aids with a higher level of evidence may have limitations regarding their specific populations, the mechanisms by which they act, as well as the interactions between them.

Dietary supplement regulation, efficacy, safety, contamination, supplementation during sports, ergolityc effects, knowledge about supplementation, supplementation and quality of sleep, and the cellular mecanisms induced by supplements are the focuses of this Special Issue, but there is no limit to these topics.

Importantly, dietary strategies involving train gut, sleep low, train low, train high, carbloading, and other fueling strategies, as well as energy restriction, are also within the scope of this Special Issue.

This Special Issue of Nutrients includes articles that provide novel insights into how supplements and dietary strategies may counteract metabolic disruptions and improve athletic performance.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Background: Beetroot juice, the most commonly used route of dietary nitrate supplementation, is theorized to enhance physical performance. However, its effects on different aspects of physical performance, different populations, and optimal supplementation strategies remain controversial. The purpose of this study was to investigate the effects of beetroot juice (nitrate-rich) on physical performance, to compare its effects between professional athletes and non-athletes (healthy individuals), and to determine the optimal supplementation strategy. Methods: A systematic search was conducted on the Web of Science, Embase, PubMed, Cochrane Database, SPORTDiscus, Scopus, and CINAHL databases. Reviewers conducted study screening and selection, data extraction, and assessment of methodological quality using the AMSTAR 2 tool. Fifteen meta-analyses were included in this Umbrella Review. A narrative and quantitative synthesis was performed. Standardized mean differences (SMD) and 95% confidence intervals (CI) were reported. Results: (1) Beetroot juice significantly improved muscle strength (SMD = 0.08, p < 0.001), but the effect size was negligible. (2) Aerobic Endurance: Beetroot juice significantly improved VO2max (SMD = 0.16, p = 0.033) in healthy adults; however, the effect size was negligible. (3) Lactate Tolerance: beetroot juice significantly improved TTE (SMD = 0.25, p = 0.034) and YO-YOIR1 (SMD = 0.27, p = 0.049) performance in healthy adults, but the effect size was small. (4) Subgroup analyses revealed significant population differences: professional athletes showed significant muscular strength benefits (SMD = 0.27, p = 0.007), whereas non-athletes had more pronounced aerobic endurance improvements (SMD = 0.26, p < 0.001), but the effect size was small. (5) Nitrate supplementation timing and dose–response analysis revealed that nitrate supplementation, whether administered 2–3 h before exercise or over a prolonged period (≥3 days), produces a significant enhancement in physical performance (p < 0.01). Notably, acute improvement only has a small effect size (SMD = 0.20), while the impact of chronic supplementation is essentially negligible (SMD = 0.13). A dosage of 8.3–16.4 mmol NO3− (515–1017 mg) showed a significant improvement (SMD = 0.14, p = 0.029), although the effect size was negligible. Conclusions: Acute (2–3 h pre-exercise) and chronic (≥3 days) supplementation with beetroot juice to achieve nitrate levels of 8.3–16.4 mmol (515–1017 mg/d) are recommended to enhance physical performance. Beetroot juice shows population-specific effects: proper beetroot juice supplementation improves muscular strength in professional athletes and aerobic endurance in non-athletes. Moreover, appropriate supplementation of beetroot juice can improve the lactate tolerance in healthy adults. Full article
