Special Issue Information

Dear Colleagues,

This second volume of this Special Issue follows on from the success of the first. We thereby invite you to publish your research in this Special Issue of “Sports Medicine: Nutritional Sciences and Nutritional Biochemistry”.

Sport medicine is now a well-established field with many different applications, ranging from well-being to competitive sports up to professional athletes. In particular, as in other sectors, nutrition is experiencing exponential growth in interest, leading to the drive to have an increasingly scientific and systematic approach to the subject.

This Special Issue aims to place a particular emphasis on sports nutrition, in particular evaluating the aspects of hormonal and biochemical regulation. This includes “classic” aspects of sports nutrition, such as pre- and post-workout, pre- and post-competition nutrition, nutrition during physical activity, dietary supplementation with particular focus on ergogenics (creatine, BCAA, HMB, beta-alanine, etc.) and sport foods (protein powders, bars, gels, etc.), as well as innovative aspects such as the analysis of metabolites through urine or miRNAs to evaluate the nutritional status and consequent performance. Finally, we include new concepts that may involve AI and computational models, such as fractals.

Potential topics include, but are not limited to, the following:

  • Nutrition “peri” workouts;
  • Nutritional supplements and performance;
  • The role of metabolomics in sports nutrition;
  • The role of miRNA in sports nutrition;
  • A new consideration of the metabolic pathways applied to sport nutrition;
  • Ergogenics and sport food: new insights;
  • AI and sports nutrition;
  • Nutrition and body composition evaluation.

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. Life is an international peer-reviewed open access monthly 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 2600 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.

This case report examines the correlation between hydration, weight variation, and perceived effort in a 43-year-old amateur athlete during a self-supported 81.5 km crossing of Death Valley, completed over 3 days with significant elevation changes. Studies have shown that a body mass loss greater than 2–3% can lead to an increased perception of effort and a decline in performance. Specifically, during passive and active heat exposures, the average body mass loss was found to be 1.4 ± 0.3% and 4.1 ± 0.7%, respectively. Salivary osmolarity has demonstrated a sensitivity of 86% and specificity of 91% in diagnosing dehydration of ≥ 2%, suggesting its potential as a non-invasive indicator of hydration status. The subject monitored their own body weight, hydration (via salivary osmolarity), and perceived effort using a rate of perceived exertion (RPE) scale. Nutritional intake included isocaloric meals and nutritional bars, and hydration was managed using water and a hydroelectrolytic solution. Key bioimpedance parameters were measured to assess body composition and hydration status. A progressive decrease in body weight correlated with an increase in perceived effort (RPE score) and salivary osmolarity. Resistance (Rx) remained stable, while reactance (Xc) showed a biphasic trend and was inversely correlated with the sodium/potassium ratio (NAK). There were significant linear correlations between perceived effort and both weight loss and salivary osmolarity, indicating that salivary osmolarity is a potential early predictor of these changes. The findings highlight a linear correlation between weight loss, perceived effort, and salivary osmolarity, suggesting that monitoring salivary osmolarity would be useful for the field assessment of hydration and exertion. Further research with larger populations is necessary to validate these observations. Full article
