Determining Whether A Spot Urine Sample Is An Accurate Indication Of A Person's Hydration Status, Hannah Glidewell

Health, Human Performance and Recreation Undergraduate Honors Theses

The purpose of this study was to determine what technique would be an accurate measurement of an individual’s hydration status. According to current research on hydration assessment, the “gold standard” to assess the hydration of an individual is by measuring their total body water (Armstrong, Lawrence 2007). This is the most accurate measurement in a laboratory setting, but finding a measurement that works during a real time setting has been a challenge. It was proposed that a spot urine sample would provide more accurate results than a first- morning urine sample when compared to a 24-hour urine sample set as …

The Effects Of Mild Dehydration On Cycling Performance In The Heat, Elika Hamer

Health, Human Performance and Recreation Undergraduate Honors Theses

Abstract

Introduction: Hypohydration exceeding 2% of body mass (bm), affected by heat and thirst level, leads to decreased athletic performance. Both physiological and psychological factors of dehydration have an impact on an athlete’s perceived performance. However, it is unclear whether the effects of psychological, physiological, or both have a negative impact on athletic performance caused by mild hypohydration. Purpose: The purpose of this study was to determine if mild hypohydration affects exercise performance in trained cyclists while blinding their hydration state. Methodology: Eleven competitive male cyclists participated in two blinded experimental trials, hypohydrated and euhydrated states by intra-venous infusions. The …

Does Hydration Impact Memory: A Systematic Review, Kelsey Ellis-Lepard

Health, Human Performance and Recreation Undergraduate Honors Theses

With 60% of the adult human body composed of water it makes sense that maintaining proper hydration levels is important to survival as well as living a healthy life. Water has many roles throughout the human body: thermoregulation, being a carrier, being a lubricant, and acting as a reaction medium. As a carrier, water is responsible for allowing exchanges between cells, interstitial fluid and capillaries. In addition, water regulates the blood volume and allows blood circulation. Since water is responsible for these tasks, many systems in the body as well as the brain are reliant upon proper hydration levels to …
