Special Issue Information

Dear Colleagues,

Most researchers interested in studying the effects of fatigue on sports performance usually measure fatigue as the absence of energy (i.e., if you are fatigued then you are not energetic). However, recent evidence suggests that energy and fatigue are two biologically distinct unipolar moods, with their own mental and physical characteristics. Furthermore, studies that have examined energy and fatigue as two separate constructs suggest that feelings of energy contribute to motivations to get things done, while feelings of fatigue help us decide when a rest period is needed in order to avoid fatigue-induced errors and injuries. While these findings were explored in healthy young adults, they have not yet been studied in a sports setting.

This research topic calls for submissions that help to identify biomechanical, physiological, immunological, psychological and epigenetic factors associated with feelings of energy or fatigue alone or both moods simultaneously. We invite researchers who examine interventions that influence feelings of energy or fatigue separately, or both simultaneously, in a sports performance setting. Researchers can explore different interventions (i.e., sleep, exercise, and drugs) that modify these moods, when measured as two separate moods, to help identify how these moods influence sports performance. We invite original research, case reports, reviews, systematic reviews, and meta-analyses to this Special Issue.

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. Sports 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 1800 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.

Exercise-induced fatigue is a multi-origin physical and mental phenomenon. Efforts to diminish the above predisposition may contribute to endurance, along with athletic well-being, while development of nutritional strategies to optimize condition and exercise performance are essential issues for athletes and trainers. Dietary amino acids are being discussed for their specific health-promoting properties beyond their role as building blocks of proteins. Glutamine, along with cysteine, are two kinds of amino acids that are reported extensively for their anti-oxidation, anti-inflammation, and immune-regulation properties, and are promising in sport applications. In the present study, we designed a randomized, placebo-controlled, crossover trial to examine effects of 7-day supplementation of cystine/glutamine mixture (Cys2/Gln) on self-reporting fatigue index (ratings of perceived exertion, RPE), energy metabolism, and inflammation. We also employed a C2C12 myotube model to examine the capacity of cystine for fatty acid utilization. Cys2/Gln supplementation alleviated fatigue by decreasing RPE and enhanced fatty acid oxidation during a 60 min endurance exercise in human trials, while cystine increased fatty acid utilization in C2C12 myotubes by enhancing mitochondrial respiration. In summary, Cys2/Gln supplementation exerts positive effects on ameliorating exercise-induced fatigue, mechanisms of which can be attributed to enhancement of fatty acid utilization. Full article
