A Novel Exercise Device For Users In Wheelchairs: A Study Of Abdominal Muscle Activation, Rebecca Jo Campbell

Master's Theses

This study evaluates the use of a wheelchair balance board. The balance board was created as a sensory stimulation tool for users with various disabilities. It was originally designed to create vestibular stimulation for the person after they were loaded on.  This study was used as a way to test if the balance board could be used for other things such as physical therapy and exercise.  Ten able-bodied individuals were used to show the functionality of the device.  They were asked to perform six different abdominal exercises while the muscle activity of their rectus abdominis and external obliques was measured …

Physical Activity Patterns Using Accelerometry In The National Weight Control Registry, Victoria A. Catenacci, Gary K. Grunwald, Jan P. Ingebrigtsen, John M. Jakicic, Michael D. Mcdermott, Suzanne Phelan, Rena R. Wing, James O. Hill, Holly R. Wyatt

Kinesiology and Public Health

The National Weight Control Registry (NWCR) was established in 1993 to examine characteristics of successful weight-loss maintainers. This group consistently self-reports high levels of physical activity. The aims of this study were to obtain objective assessments of physical activity in NWCR subjects and compare this to physical activity in both normal-weight and overweight controls. Individuals from the NWCR (n = 26) were compared to a never‑obese normal-weight control group matched to the NWCR group’s current BMI (n = 30), and an overweight control group matched to the NWCR group’s self-reported pre-weight-loss BMI (n = 34). Objective assessment of physical activity …

Impact Of Exercise On Brain Responses To Visual Food Cues: An Fmri Study, Nero Erezi Evero

Master's Theses

On the basis of a strong body of data, the Institute of Medicine currently recommends at least 60 minutes of exercise per day to prevent body weight gain overtime.  Previous studies have shown that there is no compensatory increase in food intake with this dose of exercise. Ultimately, the brain decides whether to alter food intake.  Surprisingly, no published studies have assessed the impact of exercise on brain activation.  Using functional magnetic resonance imaging (fMRI) and an appetite questionnaire, we investigated the effects of a single bout of aerobic exercise on brain responses to visual food cues and subjective appetite …

Intramuscular Temperature Responses Of The Vastus Lateralis And Semitendinosus During Squatting And Stretching With Whole Body Vibration, Joshua Gant Allen

Theses and Dissertations

This study was a randomized control trial. The purpose of this study was threefold: 1) to determine if intramuscular temperature (IMt) increases in the semitendinosus (ST) are similar to the vastus lateralis (VL) during standard WBV static squatting; 2) to determine if changes in intramuscular temperature of the hamstrings is different from a standard static semi-squat when undergoing WBV in a static stretching position; and 3) to determine if shorter overall durations as is typically used for stretching protocols (i.e. 5 repetitions of 30s each), will result in IMt increases. Twelve subjects (all males), with tight hamstrings completed this study …

Recreation Participation And Conservation Attitudes: Differences Between Mail And Online Respondents In A Mixed-Mode Survey, Alan R. Graefe, Andrew J. Mowen, Elizabeth Covelli, Nate E. Trauntvein

Kinesiology and Health Science Faculty Publications

This study reports a comparison of demographics, outdoor recreation activity patterns, and attitudes toward conservation issues collected via mail and online survey methods within a mixed-mode survey. Pennsylvania residents, randomly sampled by Survey Sampling, Inc., were invited in a pre-survey letter to complete the survey online, or through a paper survey mailed to their homes. Differences in outdoor recreation participation were generally small for wildlife-related activities, and were greater among non-wildlife-related outdoor recreation activities, with the Internet respondents generally reporting higher rates of participation. Analyses controlling for demographic variables showed a confounding influence on the relationships examined. Internet respondents tended …

An Economic Impact Analysis For The 2nd Annual Bluegrass, Old-Time Music And Dance Festival In The Village Of Stone Mountain, Georgia., Kevin A. Lane

Master's Theses

@font-face { font-family: "Cambria"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0in 0in 10pt; font-size: 12pt; font-family: "Times New Roman"; }div.Section1 { page: Section1; }

The basis for this thesis was to study the decline in baseball participation amongst African American youth through the lens of social learning theory. This was done in conjunction with interviews with 10 young African American non-baseball players, ages 11-13, who resided in an urban setting in a northeastern city. Because of the paucity of African Americans in Major League Baseball today, social learning theory, a philosophy heavily predicated on the influence of role models, was seen …

The Genetic Influence On The Placebo Effect Specific To Exercise Performance, Jennifer Wu

Masters Theses, 2010-2019

Placebo treatments can be used to elicit many different physiological responses; however, the underlying mechanisms responsible remain unclear. Recent research has shown the possibility of a genetic influence on the placebo response in patients with mood disorders. In this study, we attempted to establish a similar relationship in healthy college-aged students. Force production was measured by isometric knee extension of the quadriceps muscles using maximum voluntary contractions (MVC). Subjects were given placebo treatments disguised as an undisclosed sports supplement with the information that the supplement was previously shown to provide immediate strength improvements following ingestion. Subject DNA was genotyped for …

Effect Of Diet Induced Weight Loss And Exercise On Hscreactive Protein In Sedentary Postmenopausal Women, Jennifer Donnelly

Masters Theses, 2010-2019

Cardiovascular disease (CVD) risk factors, such as increased body fat, dyslipidemia, and high sensitivity C-reactive protein (CRP) levels are intensified in postmenopausal women. CRP has been reported as an independent indicator of risk for cardiovascular events. CRP is affected by multiple factors such as age, race, body mass index (BMI), and physical activity level. The purpose of this study was to compare the effects of an exercise intervention on traditional (BMI, percent body fat, waist circumference, physical activity level) and non-traditional (CRP) risk factors for cardiovascular disease to a dietary intervention program in sedentary, postmenopausal women. Twenty apparently healthy postmenopausal …

The Relationship Between Physical Activity Recommendations And Diabetes Risk Factors In Pregnant Women, Kelly Mattran

Masters Theses, 2010-2019

BACKGROUND: Changes in maternal insulin sensitivity throughout pregnancy may help supply nutrients to a growing fetus; however, the changes may concomitantly increase the mother and child’s risk for diabetes and chronic diseases. Regular physical activity (PA) positively impacts precursors for diabetes, but the impact of PA throughout gestation is less studied. The purpose of this study was to examine the relationship between meeting PA recommendations and diabetes risk in pregnant women. METHODS: A total of 23 pregnant women were recruited for participation. Venous blood samples, questionnaires, and anthropometric measurements (height, weight, and hip/waist circumferences) were ascertained during a single session. …

Concurrent Aerobic Exercise Interferes With The Satellite Cell Response To Acute Resistance Exercise In Mhc I Muscle Fibers, Lyle W. Babcock

Masters Theses, 2010-2019

Purpose: Concurrent training attenuates hypertrophy compared to resistance training alone, and does so in a fiber-type specific manner. The mechanism responsible for this ‘interference’ is unclear, and satellite cell physiology, an important hypertrophic factor, has not been examined within this context. Therefore, the purpose of this investigation was to assess the fiber-type specific satellite cell response to acute resistance, aerobic and concurrent exercise. Methods: Eight recreationally active college-aged males (23±1 yrs, 83.4±3.6 kg, 181±2 cm, and 48.5±1.6 ml/kg/min) performed 3 sets of 10 repetitions with a fourth set ≥ 10 repetitions at 75% of 1RM for both unilateral leg extensions …

Comparison Of Carotid, Brachial, And Popliteal Intima Media Thickness Among Sedentary And Physically Active Subjects Between 40 And 60 Years Old, Amanda Robinson

Masters Theses, 2010-2019

The purpose of the current study was to determine the effect of long term versus recent training on intima-media thickness (IMT) and if this effect is localized in the vascular beds of the tissues directly involved in the activity. Thirty-four male subjects (aged 49.69 ± 6.48 years) were recruited and divided into the following groups: sedentary (SE), recent aerobic exercisers (RE) or long-term aerobic exercisers (LE). Carotid, brachial, and popliteal artery IMT was measured using B-mode ultrasonography. Diet, physical activity, and C-reactive protein (CRP) were measured as well. Carotid IMT was not significant (p=0.974) between the groups, with SE values …

The Effects Of Sr2w-1 Supplementation On High-Intensity Cycling Performance And Lactate Metabolism, Kevin A. Murach

Masters Theses, 2010-2019

Purpose: The purpose of this investigation was to examine the effects of SR2W-1 herbal supplementation on cycling performance, muscle and blood lactate, and various physiological parameters including blood glucose, heart rate (HR), rating of perceived exertion (RPE), oxygen consumption (VO2), expired ventilation (VE), respiratory exchange ratio (RER), and femoral artery blood flow. Methods: Seven recreational cyclists (Age: 26.7 ± 9.8 yrs, Height: 172.5 ± 13.3 cm, Weight:67.1 ± 10.7 kg, and VO2max: 59.5 ± 11 mL/kg/min) performed 20-min of steady-state cycling (~85% VO2max, 212.1 ± 25.0 W) followed by three 1-min high intensity intervals at VO2max workload (272.9 ± 26.9) …

The Effects Of Sr2w-1 Supplementation On Cycling Performance And Muscle Fatigue, Tara Ali Ata

Masters Theses, 2010-2019

The purpose of this investigation was to examine the potential effects of SR2W-1 supplementation on cycling performance, central fatigue, and a variety of physiological parameters, including blood lactate, blood pH, heart rate (HR), rating of perceived exertion (RPE), oxygen consumption (VO2), expired ventilation (VE), and respiratory exchange ratio (RER). Methods: Five recreational cyclists (38 ± 8 yr, 168.4 ± 4.3 cm, 68.8 ± 5.6 kg, and 54.4 ± 2.6 mL/kg/min) performed 20-min of steady-state cycling (~85% VO2max) followed by three 1-min high intensity intervals at VO2max with 30-sec active recovery periods at 100 W, 15-min passive recovery period, and a …

Volume Of Physical Activity And Hemostatic Variables In Pregnant Women, Christine Nicewonger

Masters Theses, 2010-2019

Purpose: This study investigated the relationship between blood coagulation and fibrinolytic potential and physical activity. Physical activity levels to predict blood coagulation and fibrinolytic potential were also examined. Methods: Twenty-three pregnant women, aged 19-34 yrs, had a fasted blood draw between 6 and 10 a.m. analyzed for tPA antigen, tPA activity, PAI-1 antigen, and vWF antigen. Trimester specific volume of leisure time physical activity was assessed by the Modifiable Activity Questionnaire (MAQ) and converted to METmin/wk. Based on MAQ results, women were grouped as meeting (“active”) or not meeting (“sedentary”) physical activity recommendations established by American College of Obstetrics and …

Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush

Masters Theses & Specialist Projects

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter …

The Effects Of Caffeine On A Time-Trial Cycling Performance, Chris Tucker

Kinesiology Student Research - Archive

Caffeine is one of the most widely consumed drugs in the world. Its mechanism of action has given it credibility as an ergogenic aid. It has been shown to stimulate the mobilization and oxidation of free fatty acids (FFA), thus sparing muscle glycogen. Caffeine is also well documented as a central nervous stimulant and its direct effect on the central nervous system is found in its role as an adenosine antagonist. It is thought to inhibit adenosine from blocking neuronal transmission thus increasing pain tolerance and reducing fatigue.

Aerobic Capacity Of Wheelchair Basketball Players During Arm Crank Ergometry Vs Treadmill, Steve Quaker

Kinesiology Student Research - Archive

It is difficult to determine the aerobic capacity of wheelchair athletes by the accepted standards and methods of testing. The levels of disability and the associated functionality of the individual as well as wheelchair design itself impacts the measure of VO2 peak. VO2 peak is the maximum volume of O2 that a person's body can transport to tissue during incremental exercise. At the current time VO2 peak is the best indicator of physical fitness of an individual.
