The Validity Of Urine Color Self-Assessment As An Index Of Hydration In Males, Daniel Layne Nixon
The Validity Of Urine Color Self-Assessment As An Index Of Hydration In Males, Daniel Layne Nixon
Graduate Theses and Dissertations
While water intake is so important, there are few practical hydration assessment techniques for the general population to use on a daily basis. The present study examined the accuracy of self-assessed urine color (Ucol) as a potential hydration assessment tool. Male college aged subjects provided a urine sample into a custom built urinal (n=76; 1.79±0.76 m, 83.9±16.0 kg). The urinal contained a picture of the 1-8 color scale and a light and dark urine color scale. Subjects were asked to give their urine color estimation as a whole number integer and to estimate if their urine was light or dark. …
Effects Of Mild Hypohydration And Hyperthermia On Cognition And Mood In Obese And Non-Obese Females, Jenna Marie Burchfield
Effects Of Mild Hypohydration And Hyperthermia On Cognition And Mood In Obese And Non-Obese Females, Jenna Marie Burchfield
Graduate Theses and Dissertations
INTRODUCTION: Information regarding effects of hypohydration (HY) and hyperthermia (HT) on cognition, mood and development of symptoms is conflicting since the two conditions often confound each other. Further, although obese individuals may have physiological impairments during heat stress, whether psychological impairments occur with HY and HT is unknown. PURPOSE: To assess the independent and combined effects of mild HY and HT on cognition, mood, and the development of symptoms in obese and non-obese females. METHODS: Twenty-two healthy females (11 non-obese, 22±2y, 61±6kg, 25±4% body fat; 11 obese, 22±2y, 80±18kg, 44±5% body fat) volunteered in two randomized, repeated-measures trials, involving passive …
Hypohydration And Mood State In Free-Living Males And Females, Thomas Edward Vidal
Hypohydration And Mood State In Free-Living Males And Females, Thomas Edward Vidal
Graduate Theses and Dissertations
Previous research has shown that acute dehydration can result in changes in mood. These changes have been reported in less than a 1% loss in total body water. However, the effect of hypohydration (i.e., reflected through high urine concentration) on mood in free-living conditions has not been studied. PURPOSE: The present study was designed to determine if hydration status is associated with mood within the general population under free-living conditions. METHODS: A group of 103 apparently healthy subjects (49 male, 54 female, 41±14 y, 1.7±0.1 m, 76.1±16.9 kg) completed three visits separated by a week. Mood was assessed by the …
