The importance of adequate hydration and nutrition during exercise has been emphasized for years. It is generally commonly admitted that during exercise, dehydration—the dynamic loss of body water through sweat, respiration and urine losses—may handicap physiological functions and subsequently lead to decreased cognitive and physical performance quality. This should not come as a surprise as we humans are primarily composed of water, and the circulating water inside the body plays a role in the regulation of heat loss, the maintenance of cardiac output, oxygen and nutrients delivery to the working muscles, and waste removal. Much of our understanding of how dehydration impacts the capacity of humans to exercise has been acquired through the use of a single, potentially naïve, research paradigm in which the typical participant exercises once while being well-hydrated, and again while being dehydrated, with the researchers not considering the extent of the habituation this participant has had with dealing with daily, repeated training-induced dehydration. It is intuitive to believe that, as it is possible for athletes to adapt to the effect of heat or hypoxia, for example, daily exposures to dehydration could lead to specific adaptations that would render the athlete more resilient to the effect of dehydration, either from a physiological, physical, or cognitive perspective. Research on this topic is in its infancy, but promising. However, results from field studies strongly suggest that humans do possess the intrinsic capacity to habituate to dehydration. Indeed, some of these studies have highlighted that humans can achieve formidable physical performance while being dehydrated by 5 to 10% of their body mass. This Special Issue invites submissions for original laboratory- or field-based studies, as well as case reports, looking at how habituation to dehydration modulates physiological responses to the acute effects of dehydration during exercise and, ultimately, whether this potential adaptative capacity offers some form of protection for physical and cognitive-related performances. Papers reporting on the incidence of health issues in individuals habituated to being dehydrated by daily exercise in warm/hot or humid ambient temperatures are particularly welcome.

Manuscripts can be submitted until the deadline. All papers will be 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 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 2400 CHF (Swiss Francs).
