Effect Of Hydration Status On Post-Synaptic Cutaneous Vasodilatory And Sudomotor Responses, Ashley Six

Health, Human Performance and Recreation Undergraduate Honors Theses

"Purpose: Previous research shows dehydration decreases sweating and skin blood flow during heat stress but it is unknown whether these decrements are from pre-synaptic (i.e. central nervous system) or post-synaptic (i.e. sweat gland/blood vessel) alterations. The purpose of this study was to determine whether dehydration affects post-synaptic sweating and skin blood flow responses. We hypothesized that dehydration will negatively affect post-synaptic sweating and both endothelium-dependent and independent vasodilation. Methods: 12 males (age= 25 ± 3 y, height = 178.4 ± 5.1 cm, body mass = 75.9 ± 10.9 kg) participated. 24 h before each trial, subjects were passively heated for …

Hydration Biomarkers: Creating A User-Friendly Hydration Assessment Technique, Jenna Burchfield

Health, Human Performance and Recreation Undergraduate Honors Theses

Despite the necessity of euhydration, an optimal, user-friendly, accurate hydration assessment technique fails to exist for the general population. The primary reason for this study is to validate a new hydration assessment technique, which utilizes no equipment or technical expertise to administer. We hypothesize that the number of urine voids over 24-hrs will correlate to hydration status. We used an observational research design in the field, recruiting fifty healthy individuals (n=24 females) 18-39 years old from the Northwest Arkansas area. Age 22±4 years, body mass 75.01±17 kg, height 168.6±22.6 cm, body fat 20.4±9 %. Individuals abstained from caffeine and alcohol …

Four Weeks Of Controlled Frequency Breathing Training Reduces Respiratory Muscle Fatigue In Elite College Swimmers., Alex Robert Burtch 1991-

Electronic Theses and Dissertations

Controlled frequency breathing (CFB) is a common swim training modality that involves holding one’s breath for ~12 strokes before taking another breath. We sought to examine the effects of CFB training on reducing respiratory muscle fatigue (RMF). Elite swimmers (n = 25) were divided into either the CFB or a group that breathed regularly, every ~3rd stroke. The training intervention included 16 sessions of 12x50-m repetitions with either breathing pattern. RMF was defined as the drop in maximal inspiratory mouth-pressure (MIP) between rest and 46 seconds after a 200 yard free-style swimming race (~114 seconds). Pooled results demonstrated a reduction …

Fueling Performance: Determining The Efficacy Of Low-Carbohydrate Diet Models For Athletic Populations, Chelsea Jackle

Honors Theses

Advocates of low-carbohydrate (LC) diets assert that these diets help lessen dependence on sugar while aiding in the metabolism of fat tissue. Additionally, it is believed that lipolysis helps dieters feel more energetic, lose weight, and improve physical performance. For these reasons, many athletes and active people are drawn to diets such as the Atkins Diet, the South Beach Diet, the Paleo Diet, and the Zone Diet. According to current evidence, excessive weight loss, ketosis, reduced glycogen availability, dehydration, and increased stress hormone levels make LC diets that severely limit carbohydrates disadvantageous for athletes. Although LC diets are widely followed, …

Sex Differences In Whole Body Gait Kinematics At Preferred Speeds, Dustin A. Bruening, R. Frimenko, C. Goodyear, A. Fullenkamp

Faculty Publications

Studies on human perception have identified pelvis and torso motion as key discriminators between male and female gaits. However, while most observers would advocate that men and women walk differently, consistent findings and explanations of sex differences in gait kinematics across modern empirical studies are rare. In the present study we evaluated sex differences in whole body gait kinematics from a large sample of subjects (55 men, 36 women) walking at self selected speeds. We analyzed the data through comparisons of discrete metrics and whole curve analyses. Results showed that in the frontal plane, women walked with greater pelvic obliquity …

Participants kept 7-day, weighed food records to report their diets, including dairy intake. Insulin resistance was assessed using the homeostatic model assessment (HOMA). The Bod Pod was used to measure body fat percentage, and accelerometry for 7 days was used to objectively index physical activity. Regression analysis was used to determine the extent to which mean HOMA levels differed across low, moderate, and high dairy intake categories. Results showed that women in the highest quartile of dairy consumption had significantly greater …

Progressive Resistance Exercise With Eccentric Loading For The Management Of Knee Osteoarthritis., Haniel J. Hernandez, Valerie Mcintosh, Azadeh Leland, Michael O. Harris-Love

Exercise and Nutrition Sciences Faculty Publications

INTRODUCTION: The patient was a 58-year-old African-American male with radiographic evidence of bilateral knee osteoarthritis (OA). He participated in a standardized 12-week eccentric strengthening program within a Veterans Affairs (VA) medical center.

BACKGROUND: The use of an eccentric training paradigm may prove to be beneficial for older adults with knee OA since eccentric muscle actions are involved in the energy absorption at the knee joint during gait and controlled movement during stair descent. Furthermore, in comparison to standard muscle actions, eccentric muscle actions result in higher torque generation and a lower rate of oxygen consumption at a given level of …
