State of hydration and rate of sweating futsal players from at competitive situation in the heat
Abstract
One of the main ways of dissipating heat is by sweating, and the identification of its rate among athletes is necessary in order to prevent an athlete from collapsing due to heat an inappropriate hydration. This study aimed to identify the status of hydration and sweat rate of amateur female ́s indoor soccer players in Minas Gerais during a game in the 3rd phase of the Games do Interior de Minas -JIMI, 2008 edition. We evaluated 12 female athletes aged 20.3 ± 3.7 years and VO2maxof 56.9 ± 4.7 ml(kg.min)-1. The sweat rate of athletes was identified by the difference in weight before and after the competition, plus the amount of fluid intake during the game, divided by game time. The hydration during the competition was performed with water ad libitum, and environmental conditions of this game were 32ºC and 67%UR. The average sweat production of the athletes was 16.2 ± 5.9 mL/h ranging from 9.4 to 28.4 mL/h. It can be possible to observe that is a wide variation in sweat rate of athletes, and they must be mindful of their hydration so as not to dehydrate and thus may have changes in their performance during games and even on their health.
