• Introduction: A proper corporal hydration, physical activity and physical fitness level are three factors closely related to people’s health.

  Objective: This study aims to determine the relationship among body water percentage, assessed with anthropometric parameters and the amount of physical activity and also fitness level of a group of university women students.

  Method: 57 women aged 21.02 ± 2.45 years were measured and weighed by Tanita Segmental BC-418MA with the purpose of obtaining results of body water, BMI and body fat percentage. Ipaq-Short Form was used to quantify physical activity. As for the fitness level, the test was conducted by Forest Service, and thus determine VO2Max (n = 36) by using the Polar Team program. For the Pearson correlation (r), SPSS 22.0 for Windows was used.

  Results: The results indicate significant correlations (p<0.001) between both body fat percentage and BMI, and between the VO2Max (p <0.05) and body water percentage.

  Conclusions: Body water percentage decreases as body fat percentage does, and BMI increase when increasing VO2max. The body fatty tissue composition and the fitness level modified the body water percentage of the analyzed group.
