Special Issue Information

Dear Colleagues,

This Special Issue of the Nutrients journal, titled “Nutritional Supports for Sport Performance”, invites the submission of high-quality research papers and reviews that advance our understanding of how nutrition influences sports performance. We aim to gather a comprehensive collection of studies that explore various aspects of sports nutrition, including but not limited to, the impact of macronutrients, micronutrients, supplements, hydration strategies, and timing of nutrient intake on athletic performance, recovery, and overall health. Contributions may also cover dietary strategies for different types of sports, personalized nutrition, the role of gut microbiota in performance, and nutritional challenges faced by athletes. We welcome studies involving athletes of all levels, from amateur to elite, as well as research that addresses specific needs of special populations engaged in sports activities.

This Special Issue seeks to provide insights that can inform practice and policy, and help athletes, coaches, nutritionists, and sports medicine professionals to optimize performance through evidence-based nutritional strategies. Submissions that provide new insights into the mechanisms by which nutrition can affect sport performance, as well as those exploring emerging trends and innovations in sports nutrition, are particularly encouraged.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background: The evidence about the synergy of combining caffeine (CAF) and nitrates on exercise performance has not been summarized, although there is a possibility of additive/synergistic effects of the co-ingestion of these substances given their different mechanisms of action in central (CAF) and peripheral tissues (nitrates). Objectives: The aim was to analyze the effects of co-supplementation of CAF and nitrates on sports performance in comparison to the isolated ingestion of these substances. Methods: The databases of PubMed, Web of Science, Medline, CiNAHL and SPORTDiscus were used until June 2024 following PRISMA guidelines. Randomized controlled trials, at least one single-blind trial, conducted in adults were considered. A meta-analysis was performed using the random effects model to calculate the standardized mean difference estimated by Hedges’ g and 95% confidence intervals (CIs) for studies with four arms. Results: Six studies were included (N = 95). The meta-analysis revealed that caffeine and nitrates supplementation (CAF+nitrates) did not enhance performance in time trials (TTs) over the CAF alone (g = −0.06; 95% CI = −0.46 to 0.35; p = 0.78) or nitrates alone (g = 0.29; 95% CI = −0.12 to 0.70; p = 0.17). CAF+nitrates did not affect heart rate during submaximal exercise trials over CAF alone (g = 0.04; 95% CI = −0.31 to 0.40; p = 0.80) or nitrates alone (g = −0.15; 95% CI = −0.50 to 0.20; p = 0.40). Likewise, CAF+nitrates did not affect oxygen uptake during submaximal exercise trials over CAF alone (g = −0.04; 95% CI = −0.45 to 0.37; p = 0.84) or nitrates alone (g = −0.29; 95% CI = −0.70 to 0.12; p = 0.16). Conclusions: CAF+nitrates did not offer further benefits on exercise performance or physiological variables from the isolated intake of CAF and nitrates. Full article
