Introduction and Purpose: With inadequate fluid intake, an athlete, starting an exercise with already low levels of hydration, tends to be reduced in performance, increase heart rate and core temperature and more serious organic impairment, such as respiratory failure, shock and death hyperthermic. The study wanted to assess the level of dehydration in trained aerobic exercise and anaerobic exercise in trained another group. Materials and Methods: 19 men was invited for convenience, aged between 20 and 49 years, able to test: two indoor bike classes, 50 minutes each, with water consumption and temperature control with air conditioning to 18 degrees. To anthropometric measurements, weight measurementsand urine collections of pre and post-class indoor bike were submitted to verify color, quantity of urine and difference of total body mass in pre-and post-test. Results: Anaerobic group consumed more water during class; the anaerobic group had urinary volume greater than pre-post test. This study shows significantly different results in the variables: lean mass, fat mass and age of participants. There was a significant correlation to body mass with water consumption in the aerobic group. Conclusions:aerobically trained subjects exhibit a greater level of dehydration, even adapted to mode and water consumption, and if they had been exposed to the test fluid restriction, their level of dehydration would result in more significant amounts, which can lead to losses considered serious.
