Crossfit trainings usually organize themselves into aerobic and anaerobic exercises, classifying their sessions as training. For all athletes and practitioners of physical activity, dehydration is a difficulty and can modify physiological responses and physical performance if the loss is 1% to 3% of body mass due to dehydration. Thus, taking into account the effects of water losses in the practice of Crossfit, the objective of the present study was to analyze the degree of dehydration in practitioners of this modality. A cross - sectional, descriptive, observational study was carried out with 30 adult individuals, with a research protocol related to the practitioner 's identification, socioeconomic variables, anthropometric nutritional assessment (Circumference of arm, triceps, arm muscle circumference, corrected arm muscle area) exercise variables and dehydration rate. It was verified that 90% of the sample ingested water during the training and 96.6% did not use a hydroelectrolytic repository during the training. It was observed that the majority had a BMI greater than 24.9 that characterized overweight, obesity grade I and obesity grade II in the evaluation scale. The highest liquid intake during training was 1 liter and 300 milliliters, the lowest being 850 milliliters. Ingestion contributed to the maximum dehydration rate of 1.32%, with a minimum of 0.22%. The rate of sweat production was also quantified, being found maximum value of 25.2% and minimum 8.7%. These data showed that water replenishment prevented body mass losses from being more pronounced. ; El entrenamiento de crossfit se suele organizar en ejercicios aeróbicos y anaeróbicos, clasificando sus sesiones como entrenamiento. Para todos los deportistas y practicantes de actividad física, la deshidratación es una dificultad y puede modificar las respuestas fisiológicas y el rendimiento físico, si la pérdida de masa corporal provocada por la deshidratación es del 1% al 3%. Así, teniendo en cuenta los efectos de las pérdidas de agua en la práctica de ...
