The Influence Of Walking Speed On Hip Muscle Activity And Lumbopelvic Movement, Kate Tarver

Health, Human Performance and Recreation Undergraduate Honors Theses

Prolonged standing induces low back pain (LBP) in at least 50% of study participants. It is hypothesized that people who develop LBP during standing have high gluteus medius co-activation; however, there is no research on how interventions, such as intermittent walking breaks, influence co-contraction. PURPOSE: Examine the effects of different walking speeds on gluteus medius co-contraction. METHODS: Four males and three females (mean age=22.5) have participated in this study. The exclusion criterion includes any previous low back or hip injury, surgery and an allergy to rubbing alcohol. Electromyography (EMG) of bilateral gluteus medius were recorded during a baseline standing trial …

Hydration Biomarkers And Water Intake In 3-13 Year-Old Boys, Zoe P. Mckinney

Health, Human Performance and Recreation Undergraduate Honors Theses

Background/Introduction: Hydration is an important aspect of health in children. Despite being important, limited information is available regarding children’s water intake and hydration. Interestingly, most studies assess hydration status based on a single random urine sample instead of a 24-h one. Purpose: The aim of this study was to examine the prevalence of dehydration and water intake in boys 3 to 13 years-old. Methods: Forty-six healthy boys were recruited for the study. Each subject recorded food and fluid intake in a diary on a Saturday and Sunday. They also collected their 24-h urine on Sunday. The 24-h sample was analyzed …

Effect Of Urinary Urge On Using Urinary Frequency As An Indicator Of Hydration Status, Mackenzie Cale

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Void Frequency (VF) has recently been determined as a valid and reliable marker of 24-hr hydration status when void urgency is controlled (i.e., urinating at “first urge”). Limitations for real world applicability of this technique are apparent because individuals often void at varying urge levels throughout the day. Purpose: The purpose of this study was to determine if urgency affects the validity of void number as a marker of hydration status. We hypothesized that void urgency would not affect the validity of void number as a way to assess hydration status. Methodology: Participants included 18 females and 13 …

Muscle Oxidative Phenotype In The Progression Of Cancer-Cachexia, Haley N. Mccarver

Health, Human Performance and Recreation Undergraduate Honors Theses

Cancer is one of the leading causes of death across the world. Cancer-cachexia is a serious complication induced by cancer resulting in whole body muscle wasting and is responsible for up to 40% of cancer related deaths. Underlying mechanisms of cancer-cachexia are not well understood; however, a loss in oxidative metabolism in skeletal muscle is apparent in cancer-cachexia. PURPOSE: To examine oxidative phenotype of skeletal muscle in tumor bearing mice during progression of cancer-cachexia. METHODS: Mice were implanted with Lewis Lung Carcinoma (LLC) or sham phosphate buffered saline (PBS) at 8 weeks of age. The tumor was allowed to progress …

Validity Of 24-H Void Duration As An Indicator Of Hydration Status, Miriah C. Hadley

Health, Human Performance and Recreation Undergraduate Honors Theses

Context: Few user-friendly hydration assessment techniques exist for the general population to use on a daily basis. Objective: This study evaluated 24-h urine duration as a valid indicator of hydration status. Design:For two trials, subjects voided into a large, medical grade container at the first urge to void. For the other two trials, subjects voided at any level of urgency they desired. Participants were given a stopwatch and asked to record the duration of each void to the nearest whole second, voiding at a “normal”, unforced pace. Specific order of the trials was randomized and counter-balanced. Setting: Materials were …

Hydration Markers And Water Intake In 3 To 13 Year-Old Girls, Cody Shopper

Health, Human Performance and Recreation Undergraduate Honors Theses

INTRODUCTION: Recent data from the National Health and Nutrition Examination Survey (NHANES) showed that more than 50% of children in the U.S. are hypohydrated. However, this assessment was based on a random single urine void which has several limitations in assessing hydration. Studies have shown that greater water consumption is associated with improved mood, cognition, increased physical activity and better overall nutrition. OBJECTIVE: To assess water intake and hydration status in 3-13 year-old girls. METHODS: 39 girls age 3-13 years-old (6.9 ± 2.9 y) collected their own urine samples for 24-hours on a Sunday. Subjects also recorded …

The Contribution Of Solid Food On Total Water Intake In 3-13 Y Children, Audrey Caroline Smith

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: Adequate hydration is important element of good health. Several studies indicate that the majority of kids are hypohydrated and do not meet dietary water intake guidelines. Some scientist also suggest that good hydration might be achieved by large consumption of food that are rich in water (i.e. fruits and vegetables). However, the information of food consumption on total water intake in children is limited.

Purpose: We evaluated the contribution of water from solid food on total water intake in children.

Methodology: For this cross-sectional study 81 children (35 female) 3 to 13 years old were randomly recruited to participate. …

The acute effects of L-theanine and Caffeine on cognition in older adults

Tilley, L., Gray, M., Stone, M., & Binns, A.; Human Performance Lab; University of Arkansas; Fayetteville, AR.

Introduction: Cognitive decline is an impairment that affects many adults and has the potential to be decelerated. Previous studies show that caffeine and L-theanine positively affect cognition in a young population. L-theanine is an amino acid found in tea that produces a relaxation affect. Therefore, the purpose of this study is to determine the acute effects of caffeine and L-theanine on cognition in older adults. Methodology: Fifty-three older adults …

Validity Of Daytime Urinary Frequency As A Tool For Assessing Hydration, Monica Ziebart

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: It is known that 24-h void number is a valid way to assess hydration status. However, no studies have examined if urinary frequency just during the waking hours (~18 h) is a valid indicator of hydration status. Purpose: This study was conducted in order to determine if void number during only the waking hours was a valid indicator of hydration status compared to total voids over a 24-hour period. Methods: The subjects in this study consisted of 14 males and 18 females 18-80 yrs old who were healthy and not currently taking any body fluid altering medications. This study …

The Relationship Between Habitual Dietary Protein Intake And Dual Task Performance In Sedentary, Recreationally Active, And Masters Athlete Older Adults, Whitney L. Freeman

Health, Human Performance and Recreation Undergraduate Honors Theses

As the body ages, physical and cognitive declines can result in balance and mobility deficits, but research has shown that proper nutrition and exercise can help maintain physical and mental capacity. The purpose of this study was to analyze the relationship between habitual dietary protein intake and dual task performance in sedentary (SED), recreationally active (RA), and masters athletes (MA). To measure physical activity levels, the Rapid Physical Activity Questionnaire (RAPA) was completed by all participants. The participants were placed into a high or low protein group using the ASA-24 hour dietary recall. If the participant consumed less than 0.8 …
