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. …
The Comparative Effects Of Hot Yoga And Thermoneutral Yoga On Flexibility, Heart Rate, Sweat Rate, And Mood, Hannah Kirkland Campbell
The Comparative Effects Of Hot Yoga And Thermoneutral Yoga On Flexibility, Heart Rate, Sweat Rate, And Mood, Hannah Kirkland Campbell
Graduate Theses and Dissertations
Yoga is an ancient Indian philosophy, described as a therapeutic intervention and health maintenance practice that unites the mind and body to aid healing through the combination of physical postures, breathing techniques, and meditation. There is ample research regarding yoga practiced in an environment that is thermoneutral, or in an environment that does not alter the metabolic heat production or evaporative heat loss of people. However, minimal research exists on the increasingly popular form of yoga known as hot yoga, or yoga practiced in an environment that is often humidified and 95° F or warmer. This exploratory study compared the …
The Longitudinal Effects Of Beta-Alanine Supplementation On Isometric Strength, Time To Exhaustion, And Lower-Body Isometric Torque In Female Masters Athlete Cyclists, Jordan Mckenzie Glenn
The Longitudinal Effects Of Beta-Alanine Supplementation On Isometric Strength, Time To Exhaustion, And Lower-Body Isometric Torque In Female Masters Athlete Cyclists, Jordan Mckenzie Glenn
Graduate Theses and Dissertations
Within the population of aging individuals exists a subset of competitive seniors or masters athletes (MA). As masters-level competition increases in popularity, MA must find methods to enhance individual athletic performance. Beta-alanine (BA) is an amino acid used to enhance physical capability based on ability increase intramuscular carnosine concentrations. Older adults and females have naturally lower carnosine levels compared to age- and gender-matched counterparts and may experience enhanced benefits from BA supplementation. Purpose: Therefore, the purpose of this investigation was to examine the longitudinal effects of BA supplementation on isometric handgrip strength (HG), time to exhaustion (TTE), total work completed …
The Longitudinal Effects Of Beta-Alanine On Punch Power, Punch Frequency, And Fatigue In Female Amateur Fighters, Rodger Wayne Stewart
The Longitudinal Effects Of Beta-Alanine On Punch Power, Punch Frequency, And Fatigue In Female Amateur Fighters, Rodger Wayne Stewart
Graduate Theses and Dissertations
Beta-alanine is a non-essential amino acid typically obtained in the diet via high-protein foods (beef, chicken, pork, and fish) and produced in the confines of the liver. BA is a precursor to the cytoplasmic dipeptide carnosine (beta-alanylhistidine). Carnosine is found in high concentrations in human skeletal muscle where it plays a key role in intracellular pH buffering. Research indicates BA supplementation increased punch power, punch frequency, and lactate concentrations in male amateur fighters after 28-day supplementation. There are currently no studies evaluating the effects of BA on boxing performance variables in women. Therefore, the purpose of this study was to …
The Effect Of Balance-Based Torso-Weighting On Mobility, Gait, Balance, Postural Control, And Falls Efficacy In Mobility Limited Older Adults, Jennifer L. Vincenzo
The Effect Of Balance-Based Torso-Weighting On Mobility, Gait, Balance, Postural Control, And Falls Efficacy In Mobility Limited Older Adults, Jennifer L. Vincenzo
Graduate Theses and Dissertations
Exercise is a known intervention to prevent fall risk among older adults; however, adherence is poor. Therefore, it is of interest to determine if other interventions improve function and decrease fall risk among older adults. Balance-Based Torso-Weighting (BBTW) is a non-exercise intervention that improves functional measures among adults with multiple sclerosis, yet the effectiveness of BBTW has not been assessed among older adults without progressive neurological disorders. We conducted a double-blind, randomized study to analyze the effect of BBTW on functional measures and falls efficacy among community-dwelling, mobility limited older adults after 5 days of wearing BalanceWear® for 4 hours …
The Status Of Small Group Training As Perceived By Program Administrators, Jade Alexis Dworkin
The Status Of Small Group Training As Perceived By Program Administrators, Jade Alexis Dworkin
Graduate Theses and Dissertations
This descriptive study was obtain program components and administrative perceptions of collegiate recreation small group training programs. Through an extensive review of literature and valued input from key campus recreation professionals, a preliminary survey with 30 items was created. The preliminary survey, Administrative Effectiveness of Small Group Training Programs Survey (AESGTPS), was administered electronically to collegiate recreation small group training program directors. Research questions investigated were identifying ways in which various program components may vary from institution to institution, identifying program components that were perceived to be contributing to perceived program effectiveness, and defining ways in which program administrators perceived …
The Effect Of Physical Activity Levels On Hydration Markers In Non-Athletic Free-Living Individuals, Mikell Lucas Hammer
The Effect Of Physical Activity Levels On Hydration Markers In Non-Athletic Free-Living Individuals, Mikell Lucas Hammer
Graduate Theses and Dissertations
Higher levels of physical activity requires increased fluid intake due to increased water losses via sweating. PURPOSE: To determine the effect of physical activity on hydration status and water intake. METHODS: This study involved 8 visits to the Human Performance Laboratory over 22 days. Body weight and urine measurements were taken every visit. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ), water intake by the Water Frequency Questionnaire (WFQ), and hydration status by urine osmolality (UOsm), urine specific gravity (USG), and urine color (UC). From the IPAQ subjects were classified as low, moderate and high physical activity …
Impacts Of Micrornas On Skeletal Muscle Protein Synthesis And Mitochondrial Quality, David Lee
Impacts Of Micrornas On Skeletal Muscle Protein Synthesis And Mitochondrial Quality, David Lee
Graduate Theses and Dissertations
microRNA (miRNA) post-transcriptional modification is becoming a well-established mechanism for controlling mRNA translation. microRNAs -1, -133, and -206 are under the control of skeletal muscle promoters and affect muscle plasticity and metabolic health. A detailed review on the generation and processing of miRNAs with a view to skeletal muscle brings up intriguing connections in the transcriptional connections between multiple miRNAs. Additionally, exciting new research has defined a role of miRNAs in skeletal muscle mitochondria showing an additional, direct link to metabolic function. Multiple investigations in models of exercise, aging, hypertrophy, and injury have shown how these interventions can affect miRNA …
Perceptual Differences In Children Learning To Play Golf With Traditional Or Modified (Scaled) Equipment, Lindsey Dawn Sams
Perceptual Differences In Children Learning To Play Golf With Traditional Or Modified (Scaled) Equipment, Lindsey Dawn Sams
Graduate Theses and Dissertations
The purpose of the present study was to examine perception differences of competence and enjoyment between learners using modified and traditional equipment, and the potential effects these factors could have on intent for future participation. The participants in this study were 123 children (65 girls, 58 boys) aged 7 to 17 years. Through a convenience sampling method, data was obtained through surveys measuring golf participation and self-perceptions concerning perceived competence, enjoyment and intention to continue participation. To avoid an age confound, the dataset was limited to 2nd through 5th grade children (24 traditional/ 75 modified) for secondary analyses (MANOVA and …
