The Effect Of Heavy Handrail Support On Blood Pressure Response In Normotensive Adults During Treadmill Walking, Kevin Brian Reid

Masters Theses, 2010-2019

Physiological and hemodynamic responses to handrail support during treadmill walking have shown a blunted response when compared to non-handrail support. The effects of treadmill walking, with the inclusion of “heavy” upper limb and torso activation through handrail support is yet unreported. The effect of “heavy” support through side handrail support (SHRS) and front console support (C) versus no handrail support (NHRS) treadmill walking was studied utilizing both slow/low (2.5 mph & 3% elevation) and high/fast (3.5 mph & 11% elevation) energy expenditure levels. Seventeen healthy adults (43.89 +/- 6.07 years) completed trials at both energy expenditure levels incorporating all three …

The Effects Of Different Doses Of Caffeine On A 40 Kilometer Cycling Time Trial: A Dose-Response Study, Michael Martin

Masters Theses, 2010-2019

Abstract The purpose of this study was to determine the ergogenic response to different caffeine doses of 3 mg/kg and 6 mg/kg consumed by trained cyclists 1 hour prior to a 40 kilometer cycling time trial. It was hypothesized that there would not be a difference in time trial performance following caffeine supplementation of a 3 mg/kg dose as compared to a 6 mg/kg dose. Sixteen male subjects, age 18-40, were initially assessed via a VO2max test on an indoor cycle trainer. Subjects then reported to the lab on 4 separate occasions following a 10 hour fast and a 24 …

Comparison Of Single-Use And Multiple-Use Electrodes For Sensory, Motor Threshold Amplitudes And Force Production, Lucia Maloy

Theses and Dissertations

Context: Electrodes play an important role in interfacing tissue with electrical stimulation devices. Manufacturers recommend that adhesive metallic mesh cloth electrodes be used no more than 10 times before they are discarded, however, clinically the electrodes are often used up to 30 times. Another concern is sanitation. When electrodes are used on different patients, there is a chance for cross-contamination and bacterial growth on the electrode. Objective: To compare amplitudes of perceived sensation, motor twitch and force produced at specific amplitudes using single-use electrodes that run no risk of cross-contamination, and multiple-use electrodes. Design: Mixed model ANOVA with the subject …

Influence Of Cardiac Output On Oxygen Uptake Kinetics, Crystelle Kiyoko Grant

Theses and Dissertations

The purpose of this study was to evaluate increased cardiac output (Q) on oxygen kinetics at exercise intensities above and below the lactate threshold (LT). We hypothesized the increase in Q using head-out water immersion (HOI) while treadmill running would reduce the rate constant of the fast component and reduce the amplitude of the slow component of oxygen kinetics compared with land treadmill running. Subjects (n=10) performed two 6 min exercise bouts at a 15% below and above the LT on a land and underwater treadmill following rest. A single exponential equation [VO2(t) = VO2(b) + A1•(1-e-t/TC1] was used to …

Clinical Research In Diabetes And Urinary Incontinence: What We Know And Need To Know, Suzanne Phelan, Francine Grodstein, Jeanette S. Brown

Kinesiology and Public Health

Purpose: We discuss epidemiological and clinical trial research in women with urinary incontinence and diabetes, and provide directions for future research.
Materials and Methods: Published epidemiological and clinical trial literature examining diabetes and incontinence is presented.
Results: Multiple studies have now confirmed that the prevalence and incidence of incontinence is increased in women with type 2 diabetes. Emerging evidence also suggests higher incontinence rates in women with type 1 diabetes or prediabetes. Clinical trial research suggests that weight loss can decrease incontinence in women with prediabetes. An ongoing multicenter trial will examine the effects of weight loss on incontinence in …

We're Here Now: An Exploratory Study Of The Relationships Between Tourism And Post-Migration Community Participation And Sense Of Community, Jason Draper

All Dissertations

ABSTRACT
Research has suggested that visiting a community can result in an inclination (Cuba, 1989) or likelihood of moving there (McHugh, 1990). One reason that may contribute to the decision to move is tourism experiences provide an opportunity for visitors to compare the destination to their current community and determine if voids that exist would be filled should they relocate (Haug, Dann, & Mehmetoglu, 2007). However, should tourists decide to relocate, research is needed that examines how tourists transition to being a resident (Oigenblick & Kirschenbaum, 2002) and policy implications of residential growth. The purpose of this exploratory study was …

Assessment Of Lactate Response After The Completion Of Three Different Volume Patterns Of Power Clean, Anand Date

Boise State University Theses and Dissertations

The ability of continuous lactate clearance and the inflection points of the lactate curve are two important determinants of performance of competitive field athletes. Current training practices for improving lactate tolerance such as high intensity aerobic activities and the combination of aerobic and resistance training seem to have undesired physiological adaptations (e.g. muscle loss, change in fiber types). The Role of Explosive power movements in lactate accumulation has not been studied properly. Hence, the purpose of this study was to assess lactate response after the completion of three different volume patterns of the power clean movement. Ten male recreational athletes …

Physical Activity Among Youth In A Weekend Respite Camp Program, Kathleen Felton

All Theses

The engagement in physical activity among 24 youths with disabilities was studied. Researchers examined the effects of age and gender of the youth, the parent's knowledge of physical activity recommendations, and parent's physical activity practices on physical activity engagement. Levels of physical activity participation through leisure time, work or chores, and sports were assessed. Analysis was performed to determine relationships between each of the variables and the youths' level of physical activity respectively. Results of chi-square analysis indicated that parental influence using current physical activity recommendations was correlated with the youth's level of physical activity participation through leisure. Results suggested …

Infants Born Preterm Exhibit Different Patterns Of Center-Of-Pressure Movement Than Infants Born At Full Term, Stacey C. Dusing, Anastasia Kyvelidou, Vicki S. Mercer, Nikolaos Stergiou

Journal Articles

Background: Infants born preterm are at risk for developmental impairments related to postural control.

Objective: The purpose of this study was to determine whether infants born preterm and infants born at full term differed in postural control at 1 to 3 weeks after term age.

Design: This study included 17 infants born preterm (mean gestational age=31.9 weeks, range=25.0–34.6) and 15 infants born at full term (mean gestational age=38.9 weeks, range=37.3–40.6). All infants were without diagnosed neurological or genetic conditions.

Measurement: Center-of-pressure (COP) data were recorded at 5 Hz while each infant was positioned supine on a pressure-sensitive mat …

A Family Home Evening Based Method For Improving Physical Activity Levels In Families, Megan Maughan Wyatt

Theses and Dissertations

The prevalence of physical inactivity has been recognized as a risk factor for multiple chronic disease conditions in both adults and children. Recently efforts to increase healthy behaviors have been promoted through religious groups (Ken Resnicow et al., 2002). The Church of Jesus Christ of Latter-day Saints (LDS) has a unique program called Family Home Evening (FHE) that could be used to teach and potentially improve physical activity. Six FHE lessons were designed to be taught in 6 consecutive weeks within a family environment. A total of 84 families (parents and children) were recruited for participation. Participating families were randomized …

Phosphorylation And The N-Terminal Extension Of The Regulatory Light Chain Help Orient And Align The Myosin Heads In Drosophila Flight Muscle, Gerrie Farman, Mark Miller, Mary Reedy, Felipe Soto-Adames, Jim Vigoreaux, David Maughan, Thomas Irving

Mark S. Miller

X-ray diffraction of the indirect flight muscle (IFM) in living Drosophila at rest and electron microscopy of intact and glycerinated IFM was used to compare the effects of mutations in the regulatory light chain (RLC) on sarcomeric structure. Truncation of the RLC N-terminal extension (Dmlc2Δ2-46) or disruption of the phosphorylation sites by substituting alanines (Dmlc2S66A, S67A) decreased the equatorial intensity ratio (I20/I10), indicating decreased myosin mass associated with the thin filaments. Phosphorylation site disruption (Dmlc2S66A, S67A), but not N-terminal extension truncation (Dmlc2Δ2-46), decreased the 14.5 nm reflection intensity, indicating a spread of the axial distribution of the myosin heads. The …

Reliability Of A Brief Intercept Survey For Trail Use Behaviors, Philip J. Troped, Heather A. Whitcomb, Brent Hutto, Julian A. Reed, Steven P. Hooker

Kinesiology and Public Health

Purpose: This study assessed test-retest reliability of an interviewer-administered trail survey.

Methods: An intercept survey was conducted with adults using 2 paved trails in Indiana and South Carolina (N = 295; mean age = 46.9 ± 18 y). The survey included items on frequency and duration of trail use for recreation and transportation, other patterns of trail use, and sociodemographic characteristics. Fiftyfive adults completed the survey twice (2–16 d apart; mean = 7.4 ± 2.6 d). Test-retest reliability was assessed with Spearman rank correlation coefficients, Kappa coefficients, and percent agreement.

Results: Kappa coefficients and percent agreement for 9 categorical items …

Effects Of Acute And Chronic Endurance Exercise On Intracellular Nitric Oxide In Putative Endothelial Progenitor Cells: Role Of Napdh Oxidase, Nathan T. Jenkins, Sarah Witkowski, Espen E. Spangenburg, James M. Hagberg

Exercise and Sport Studies: Faculty Publications

We sought to delineate the effects of acute and chronic exercise on the regulation of intracellular nitric oxide (NOi) production in putative endothelial progenitor cells (EPCs). Putative EPC colony-forming units (CFUEC) were cultured from blood drawn before and after 30 min of treadmill exercise at 75% of maximal oxygen uptake in active (n = 8) and inactive (n = 8) men. CFU-EC were similar between groups at baseline, but increased after exercise in active men only (P = 0.04). CFU-EC expressed lower NADPH oxidase subunit gp91 phox mRNA and elevated endothelial nitric oxide synthase mRNA in active relative to inactive …

Mechanisms Underlying Skeletal Muscle Weakness In Human Heart Failure: Alterations In Single Fiber Myosin Protein Content And Function, Mark S. Miller, Peter Vanburen, Martin M. Lewinter, Stewart H. Lecker, Donald E. Selby, Bradley M. Palmer, David W. Maughan, Philip A. Ades, Michael J. Toth

Mark S. Miller

Background—Patients suffering from chronic heart failure frequently experience skeletal muscle weakness, which limits physical function. The mechanisms underlying muscle weakness, however, have not been clearly defined. Methods and Results—The present study examined the hypothesis that heart failure promotes a loss of myosin protein from single skeletal muscle fibers, which in turn reduces contractile performance. Ten patients with chronic heart failure and 10 controls were studied. Muscle atrophy was not evident in patients, and groups displayed similar physical activity levels, suggesting that observed differences reflect the effects of heart failure, not muscle atrophy or disuse. In single muscle fibers, heart failure …

Multiple Models Can Concurrently Explain Fatigue During Human Performance, C. Matthew Laurent†, Matt Green‡

International Journal of Exercise Science

One of the most commonly and thoroughly studied paradigms of human performance is fatigue. However, despite volumes of research there remains considerable controversy among scientists regarding definitive conclusions about the specific mechanism(s) contributing to fatigue. Within the literature there are three primary yet distinctly different governing ideas of fatigue; the traditionally referenced central model and peripheral model as well as the emerging central governor model (CGM). The CGM has recently been advocated by a limited number of researchers and is suggestive of a more integrative model of fatigue when compared the traditional peripheral and central models. However, more work is …

Determination Of Force Corresponding To Maximal Lactate Steady State In Tethered Swimming, Marcelo Papoti‡, Ricardo Vitório†, Sérgio A. Cunha†, Gustavo G. Araújo†, Adelino S.R. Silva‡, Vanessa Santhiago‡, Luiz E.B. Martins‡, Claudio A. Gobatto‡

International Journal of Exercise Science

The main aim of the present investigation was to verify if the aerobic capacity (AC) measured in tethered swimming corresponds to the maximal lactate steady state (MLSS) and its correlation with 30 min and 400m free style swimming. Twenty-five swimmers were submitted to an incremental tethered swimming test (ITS) with an initial load of 20N and increments of 10N each 3min. After each stage of 3min, the athletes had 30s of interval to blood sample collections that were used to measure blood lactate concentrations ([La-]). The ACBI was determined by the abrupt increase in [La-] versus force (F). The points …
