Despite profound effects of hypohydration on important characteristics such as mood, little research documents the hydration state of healthy, free-living adults. Given the important influence
of exercise-induced sweating on total body water, habitual physical activity might modify typical fluid balance.
PURPOSE: To examine the free-living hydration state of a large adult sample, how fluid balance related to mood, and if habitual exercise influenced these relationships.
METHODS: Hydration status was examined in 231 males and 264 females (age = 21 ± 4 y) from three exercise classifications: collegiate varsity athletes (ATH, n = 101), recreational
exercisers (REC, n = 221), and non-exercisers (NON, n = 173). Investigators assigned exercise status based on team membership and/or the Godin Leisure-Time Exercise Questionnaire.
Participants completed the Brunel Mood Scale and provided a urine sample. Urine color (Ucol) was measured using an eight point color chart, ranging from very pale yellow (1) to brownish
green (8).
RESULTS: 53.2% of all subjects displayed Ucol indicative of hypohydration (all participants Ucol = 4 ± 2). No significant differences existed in Ucol between exercise categories or genders. Males,
females, NON, and REC each showed no significant relationships between Ucol and Anger, Confusion, Depression, Fatigue, Tension, or Vigour. For ATH, Ucol significantly related to Fatigue (r =
0.232), but no other mood descriptors. Male NON, male REC, male ATH, female NON, and female REC displayed no significant relationships between Ucol and any mood descriptor. Female
ATH, however, demonstrated a significant relationship between Ucol and Fatigue (r = 0.286).
CONCLUSIONS: Many free-living individuals appeared to be hypohydrated. A detectable relationship exists between hydration status and fatigue in female athletes that was not present in
other females or males.
