      Although some instruments have been validated for clinical measure of hydration status, new and currently invalid instruments are available for purchase and clinical use. Athletic trainers commonly use these instruments to assess hydration status for weight checks and body mass loss charts due to their ease of use. However, the validity of these popular instruments has not yet been established.
    • Effect of Urine Agitation on measurements of hydration status.

      Hypohydration can have significant implications on physiological functions of the body and has the potential to decrease level of performance. Hypohydration can lead to increased thermal and cardiovascular strain. • Athletic trainers are commonly required to attain urine specimen samples to assess athlete hydration status for weight checks and monitoring body mass losses. Unfortunately, immediate examination of urine samples is not always possible. • As the urine sample sits, visible and non-visible sedimentation develops. No current literature addresses the sedimentation of urine samples and what procedures should be performed to ensure an accurate hydration assessment.
