Sweating rate and water conditions in futsal athletes

Abstract

Futsal is a team sport whose main characteristic is the constant and intense movements of all athletes, leading to a highenergy expenditure. This movement leads to an increased production of heat that is lost as sweat. This study aimed to measure the sweat rate and check the water consumption in indoor soccer players. They analyzed 25 athletes, male, mean age 11.1 ± 1.3 years and weight 41.6 kg ± 12.4 kg. The initial weight and final weight were measured to determine the percentage of weight loss (% PP) and sweat rate. During training, the consumption of water was ad libitum and in the end of training session, participants were asked to urinate into a measuring cup for urine volume. The sweat rate found ranged from 2.5 to 24.4 ml / min, with an overall average of 9.4 ml / min ± 5.0 ml / min. The mean weight loss was 0.5% ± 1.4%, but there was wide variation among athletes. The average volume ingested during training was 660 ml, but as a variation of 0 to 1500 ml. It is concluded that the sweat rate, weight loss percentage and the fluid volume ingested by futsal athletes varied widely, though, most have completed training with proper hydration.
