Ana Paula dos Santos Rodrigues Murilo Soares de Castro Gilberto Eiji Shiguemoto Anderson Diogo de Souza Lino Jonato Prestes Salud exercise Hydration dehydration performance thermoregulation Currently, there is a debate about which percentage of body mass loss can compromise performance and lead to complications to athletes´ health. Most of the drinking guidelines for exercise recommend replacing all the body mass lost during exercise and drinking as much as tolerable to avoid body mass loss over 2%. A greater dehydration can compromise aerobic exercise and cognitive/mental performance in warm-hot environments and increase the risk for heat stroke, heat exhaustion and cramps. A "cardiovascular model of thermoregulation" is used to explain the thermal regulation during exercise, which proposes that sweating reduces body water content, reducing blood flow and increasing the cardiovascular strain. However, this model has been criticized by many authors, who state that sweating response is regulated by neural mechanisms that are not dependant of the cardiovascular response to the exercise. The im of this study was to review the recommendations for fluid replacement during exercise and detail the real necessity to replace all body mass lost during exercise for better performance. We searched the following electronic databases with no data limitation: national and international articles related to the subject, in the scientific portals of Capes, Scielo, PubMed, Science Direct, Highwire and randomized control trails, in English and Portuguese. The inclusion criteria was considered human studies, papers on dehydration and performance, recommendations on hydration and exercise, ingestion of electrolytic beverages in exercise and the effects of hydration status and thermoregulation. The exclusion criteria were: experimental articles and general recommendation for non athletes. 2009 artículo científico 1981-6324 https://www.redalyc.org/articulo.oa?id=93012717002 en http://www.redalyc.org/revista.oa?id=930 Brazilian Journal of Biomotricity application/pdf Universidade Iguaçu Brazilian Journal of Biomotricity (Brasil) Num.4 Vol.3 |
