Special Issue Information

Dear Colleagues,

‘’Food first’’ is a priority that is endorsed by nutrition professionals in general, and also by sports nutritionists. Although this approach has been utilized for many years, there is no reason to miss the opportunity of taking advantage of dietary supplements, in a broad sense, and of specific ergogenic aids. That being said, another potentially missed opportunity is whole foods. With this paradigm shift occurring, structured (defined aim, dose, detailed source, and consumption frequency) supplementation with whole foods can now be regarded as a justified sports nutrition strategy (beetroot juice as a ‘’new creatine’’ is a great example). However, there is a lack of data regarding evidence-based ‘’food first’’ approach in sports nutrition, which is needed as a base for establishing practical recommendations. Therefore, we invite authors willing to share their work with athletes showing the pros and cons of a ‘’food first’’ approach to sports nutrition.

This Special Issue of Nutrients, entitled “A Food First Approach in Sports Nutrition”, welcomes original research and reviews of the literature concerning this important topic.

Nitrates are an effective ergogenic supplement; however, the effects of nitrate supplements based on habitual dietary nitrate intake through diet alone are not well understood. We aimed to assess this in a group of 15 highly trained football players from Slovenian football’s First Division. Participants underwent two separate Cooper performance tests either with nitrate supplementation (400 mg nitrates) or placebo while having their nutrition assessed for nitrate intake, as well as energy and macronutrient intake. Nitrate supplementation had a statistically significant positive effect on performance if baseline dietary nitrate intake was below 300 mg (p = 0.0104) in both the placebo and intervention groups. No effects of nitrate supplementation when baseline dietary nitrate intake was higher than 300 mg in the placebo group could be concluded due to the small sample size. Nitrate supplementation did not have a significant effect on perceived exertion. The daily nitrate intake of the participants was measured at 165 mg, with the majority of nitrates coming from nitrate-rich vegetables. Full article

Melatonin (N-acetyl-5 methoxytryptamine) is an indolic neurohormone that modulates a variety of physiological functions due to its antioxidant, anti-inflammatory, and immunoregulatory properties. Therefore, the purpose of this study was to critically review the effects of melatonin supplementation in sports performance and circulating biomarkers related to the health status of highly trained athletes. Data were obtained by performing searches in the following three bibliography databases: Web of Science, PubMed, and Scopus. The terms used were “Highly Trained Athletes”, “Melatonin”, and “Sports Performance”, “Health Biomarkers” using “Humans” as a filter. The search update was carried out in February 2024 from original articles published with a controlled trial design. The PRISMA rules, the modified McMaster critical review form for quantitative studies, the PEDro scale, and the Cochrane risk of bias were applied. According to the inclusion and exclusion criteria, 21 articles were selected out of 294 references. The dose of melatonin supplemented in the trials ranged between 5 mg to 100 mg administered before or after exercise. The outcomes showed improvements in antioxidant status and inflammatory response and reversed liver damage and muscle damage. Moderate effects on modulating glycemia, total cholesterol, triglycerides, and creatinine were reported. Promising data were found regarding the potential benefits of melatonin in hematological biomarkers, hormonal responses, and sports performance. Therefore, the true efficiency of melatonin to directly improve sports performance remains to be assessed. Nevertheless, an indirect effect of melatonin supplementation in sports performance could be evaluated through improvements in health biomarkers. Full article
