Rugby is a sport where players spend most of their time performing aerobic activities but there are some moments that they are involved in anaerobic activities. According to body dehydration percentage related with weight, physiological symptoms can vary from thirst to kidney and blood circulation insufficiency. The objective of this study was to verify the sweat rate of rugby female athletes. The athletes were weighted and submitted to a BIA test before and after training. The body fat percentage reduced 0.6% on average and the dehydration percentage related with weight reduced 1.5% on average. Physiological sensations of thirst described by the athletes agree with the dehydration degree found. It does not present risks to the athletes' health, but nevertheless, it is necessary that they get conscious about the importance of an adequate hydration for the improvement of the physical performance.
