Effects Of Incorporating Body Weight As Resistance On Lower Body Strength, Yuri Rivera

Kinesiology Student Research - Archive

INTRODUCTION: Incorporating a person’s own body weight as resistance is commonly used when a person is transitioning from sedentary to starting an exercise routine. In addition, incorporating one’s own body weight as resistance is the most appropriate choice when the person has no experience or is afraid of incorporating weights into their exercise routine. For strength gains, resistance training also known as strength training is defined by using external weight or using the person’s own body weight to increase body strength. Resistance training can be defined as progressively overloading the neuromuscular system using near maximal muscle contractions against high resistance. …

Four participants (62.3 ± 6.5 yrs, Hoehn & Yahr 2-4) performed 8 weeks of treadmill training 3 times per week. Weeks 1-4 included forward walking only, while weeks 5-8 included forward and multi-directional walking. Participants were tested every 4 weeks on 4 separate occasions. Outcome …

Musical Stairs: Encouraging Physical Activity Through Persuasive Technology, Meagan Combs 15

Honor Scholar Theses

This study examined persuasive technology and its effect on participants’ motivation to engage in physical activity. A set of musical stairs was built using infrared proximity sensors, designed to make the experience of climbing the stairs more “fun”. The software was written in such a way that each step a participant took on the stairs provided a musical response. The experiment tested three conditions: the control condition (without sounds), a condition with piano note sounds, and a condition with guitar chord sounds. The results suggest that more participants interacted with the stairs during the conditions with sound compared to the …

The Effect Of Training Older Adults In Tai Chi And Compensatory Stepping On Balance Control, Hannah L. Moore Miss

Theses and Dissertations (Comprehensive)

Abstract

Introduction: In Canadian society, there is a growing prevalence of older adults and one of the main problems facing this generation today is the risk of falling. Tai Chi (TC) is a martial art that has demonstrated improvements in balance control. It uses a series of fluid movements that engage head, neck and trunk rotation while simultaneously reducing base of support. In addition, it has been demonstrated that training older adults by administering unpredictable perturbations to challenge balance better equips them to react successfully in response to balance perturbations. This study aims to determine the potential balance specific benefits …

Application Of The Transtheoretical Model: Assessing Exercise Behavior In African Americans In A Church-Based Setting, Robin Marie White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sedentary behavior rates are higher among African-American men and women than in other American races and ethnicities, placing them at greater risk for chronic illness. Routine physical activity reduces the risk of chronic health problems such as: (a) overweight and obesity, (b) type 2 diabetes, (c) hypertension, (d) coronary artery disease, (e) stroke, (f) congestive heart failure, and (g) cancers. Assessment of African-Americans' exercise attitudes in a church-based setting may provide information with which to develop effective interventions to improve physical activity. This descriptive, cross-sectional study used components of the Transtheoretical Model (TTM) to assess whether any associations exist between …

Circulating Angiogenic Cell Population Responses To 10 Days Of Reduced Physical Activity, Gayatri Guhanarayan, Julianne Jablonski, Sarah Witkowski

Exercise and Sport Studies: Faculty Publications

Circulating angiogenic cells (CACs) are a diverse group that have been identified as predictors of cardiovascular health and are inversely proportional to cardiovascular disease (CVD) outcomes. Inactivity is a growing concern in industrialized nations and is an independent risk factor for CVD. There is limited evidence regarding the impact of reduced physical activity (rPA) on different CAC populations. The purpose of this study was to evaluate the effect of objectively monitored rPA with maintained energy balance on two CAC populations (CFU and CD34+cells), intracellular nitric oxide (NOi), and genes related to NO production in active, healthy men. Participants (age 25 …

The Effects Of Exercise Training On Cognitive Reserve And Cognitive Function In Healthy Older Women, Katie Marie Becofsky

Theses and Dissertations

Cognitive reserve theory suggests that physical activity may protect individuals from cognitive decline. At the brain level, greater cognitive reserve may manifest as greater neural network efficiency. Our purpose was to investigate 1) whether participation in a 16-week walking program increased brain efficiency, and 2) whether increased brain efficiency correlated with change in fitness and task performance. Our secondary purpose was to investigate whether exercise training improved performance on a battery of cognitive tasks, particularly executive functioning performance. Seventeen healthy but sedentary women aged 60-75 years participated in a supervised walking program; eighteen women served as a non-randomized control group. …

The Percussionist Bodybuilder: Optimizing Performance Through Exercise And Nutrition, Anthony Joseph Merlino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Do preventive therapies have the potential to help avoid common injuries among percussionists? This document investigates physiological therapy and nutrition in relation to percussion performance. My interest in this subject matter is derived from my personal experiences with injuries related to the performance of percussion. Although I have studied and played percussion professionally for more than a decade, I was unaware of certain methods of rehabilitation that were available to me prior to my injuries. As I learned about the rehabilitation process through first hand experience, I discovered that my injuries were very common among percussionists. This raised the question: …

Exercise And Diet Program For The College Student, Brooks Briel

Senior Theses

Oftentimes college students can be seen going to the gym with simply no direction in exercise or nutrition. They go through the motions of exercising, but have no real understanding of what they are doing. These students may see some progress, but plateau early and find it discouraging to continue to workout. The goal of this project was to create a personal diet and exercise program that could be used by the average college student to improve their physical fitness levels. The exercise program attempts to improve body composition, cardiovascular fitness, muscular strength and endurance, and flexibility. This is done …

Muscle Physiology And Performance During Intensified Cycle Training: Impact Of Carbohydrate-Protein Supplementation, Andrew Christian D'Lugos

Masters Theses, 2010-2019

Previous studies show that carbohydrate-protein (CP) ingestion can enhance short-term recovery following exercise, thereby benefiting subsequent exercise performance and compounding physiological parameters, when compared to carbohydrate (CHO) alone. Less is known about the influence that CP supplementation may have over a long-term intervention (several days/weeks). The purpose of this investigation was to determine whether CP supplementation was effective in improving tolerance to a period of intensified training (IT), compared to CHO. Additionally, the influence of CP on recovery/ adaptation to a period of IT followed by a period of reduced volume training (RVT) was examined. Eight endurance-trained cyclists (age: 24.9±7.3 …

The Relationship Among School Playground Design And Conditions And Physical Activity Levels In Children, Ipuna Estavillo Black

UNLV Theses, Dissertations, Professional Papers, and Capstones

Almost 20% of children aged 6 to 11 years are obese in the United States, tripling over the last ten years. The rise in childhood obesity challenges nurses in their efforts to improve community health and sustainability. A decrease in physical activity (PA) levels has been associated with an increase in obesity. Schools have been identified as a primary setting to provide children adequate amounts of daily PA, and nurses working in the area of child health promotion can work with schools to provide opportunities for children to increase PA levels. The playground is one environment where children can increase …

Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli

Nevada Journal of Public Health

The purpose of this cross-sectional study was to identify perceived environmental correlates of meeting physical activity guidelines among African-American adults living in Southern Nevada. Trained interviewers phoned potential participants who lived in the 12 zip codes of Clark County, Nevada with the highest proportions of African-American residents. Respondents (n=237) answered 52 health-related and demographic questions. Slightly less than 50% of participants met physical activity guidelines. A factor analysis procedure produced two environmental variables, neighborhood safety and environmental supports for physical activity. Age, gender and educational attainment (p<.05) predicted the meeting of those guidelines (R2=.214), while neighborhood support for physical activity, neighborhood safety, and BMI failed to do so. This finding suggests that environmental factors are not strong predictors of physical activity among African- American adults, although environmental supports for physical activity approached significance. Future studies should consider assessing additional aspects of the built environment as an influence on physical activity.

Benefits Of Exercise Intervention In Reducing Neuropathic Pain, John L. Dobson, James L. Mcmillan, Li Li

Health Sciences & Kinesiology: Faculty Publications

Peripheral neuropathy is a widespread and potentially incapacitating pathological condition that encompasses more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and/or sensory neurons, and the symptoms that typify the condition are abnormal cutaneous sensation, muscle dysfunction and, most notably, chronic pain. Chronic neuropathic pain is difficult to treat and is often characterized by either exaggerated responses to painful stimuli (hyperalgesia) or pain resulting from stimuli that would not normally provoke pain (allodynia). The objective of this review is to provide an overview of some pathways associated with the development …

Voluntary Exercise Reduces Alzheimer’S-Like Pathology After Inflammation In Mice, Marielle K. Weintraub, Jordon D. White, Stephanie M. Turner, Samantha L. Hodges, Amanda Leigh Morin, Lindsey N. Sadler, Gary W. Boehm, Michael J. Chumley

International Journal of Exercise Science: Conference Proceedings

Current global statistics estimate that 44.4 million people are afflicted with dementia, and that 50%-75% of these patients suffer from Alzheimer’s disease (AD; Prince et al. 2013). AD, a progressive disorder categorized by neuronal and behavioral deterioration, is the 6^th leading cause of death in America (Alz facts and figure 2012). One hallmark pathology of AD is the presence of amyloid-beta (Aβ) in the brain, which can limit cell-to-cell communication, leading to cognitive deficits, and neuronal cell death. Although the exact origins of this disease still remain unknown, one possible catalyst of AD pathology is inflammation. Our lab has …

The Effects Of Proprioceptive Neuromuscular Facilitation Stretching On Post-Exercise Delayed Onset Muscle Soreness In Young Adults, Ryan P. Mcgrath, James R. Whitehead, Dennis J. Caine

International Journal of Exercise Science

International Journal of Exercise Science 7(1) : 14-21, 2014. Until recently, the scientific community believed that post-exercise stretching could reduce delayed onset muscle soreness (DOMS), but recent reviews of studies on the topic have concluded that pre- or post-exercise static stretching has no effect on mitigating DOMS. However, the effect of proprioceptive neuromuscular facilitation (PNF) post-exercise stretching on preventing DOMS has not been adequately studied. The purpose of this study was to determine the effect of post-exercise PNF stretching on DOMS. Young adult participants (N=57) were randomly assigned to a PNF stretching group (n=19), a static stretching group (n=20), and …

Effect Of Age On The Hemodynamic And Sympathetic Responses At The Onset Of Isometric Handgrip Exercise., Sophie Lalande, Carolyn P Sawicki, Jacquie R Baker, Kevin Shoemaker

Kinesiology Publications

Cardiac and peripheral vasomotor factors contribute to the rapid pressor response at the onset of isometric handgrip exercise. We tested the hypothesis that age enhances the sympathetic and vasoconstrictor response at the onset of isometric handgrip exercise so that the pressor response is maintained, despite a diminished cardiac function. Twelve young and twelve older (24 ± 3 and 63 ± 8 yr) individuals performed 20-s isometric handgrip exercise at 30, 40, or 50% of maximal voluntary contraction force. Muscle sympathetic nerve activity (MSNA) was measured using microneurography. Mean arterial pressure (MAP) and cardiac output (Q) were assessed continuously by finger …

International Journal of Exercise Science: Conference Proceedings

Introduction. Exhaustive exercise is associated with an increased risk of upper respiratory tract infection. Previously, allicin supplementation has been reported to reduce the incidence of common cold symptoms and production of exercise-induced interleukin (IL)-6. However, it is not clear if daily ingestion of the edible portion of whole garlic (Allium sativum) alters the exercise-induced immunological response. The present study investigated the effects of extracted garlic powder ingestion for 2 months on immune cell counts, natural killer cell activity (NKCA), as well as changes in cytokines, cortisol, and lactic acid in response to high-intensity cycling exercise.

Methods. The present …

Auto Anti Oxldl, Igm And Igg: Comparison Between Sedentary And Athletes, Juliana M B Santos, André L L Bachi, Francisco J O Rios, Tiago L. Capel, Pedro H C Vaisberg, Gislene R. Amirato, Mauro Vaisberg

International Journal of Exercise Science: Conference Proceedings

Introduction: The practice of regular physical activity contributes to reduce the prevalence of coronary hearth disease (CHD) and aerobic exercises are associated with beneficial changes in the profile of circulating lipids and lipoproteins. However in the past years the oxidative hypothesis assumed great importance in the pathogenesis of CHD. During exhaustive exercises there is a greater possibility of oxidation of LDL, forming oxidized LDL (oxLDL) that has a key role in atherogenesis. However the incidence of coronary events in athletes is lower than in sedentary persons. It is described in the literature that we can found in serum auto autoantibodies …

Changes Of Cytokines In Mouse Skeletal Muscle And Plasma By A Single Bout Of Endurance Exercise., Minjung Lee, Noriaki Kawanishi, Koichi Yada, Yungli Hung, Tsubasa Mizokami, Hiroyuki Niihara, Katsuhiko Suzuki

International Journal of Exercise Science: Conference Proceedings

Introduction: Exercise influences some cytokine levels, which is considered the body’s reaction against endogenous stress. Previous human studies demonstrated that high intensity exercise contributes to a dramatic increase of plasma cytokines like Interleukin-6 (IL-6) and Interleukin-1 receptor antagonist (IL-1ra) immediately after exercise. Recently, it has been identified that skeletal muscle produces cytokines and peptides and they exert both paracrine and endocrine effects. However, the sequential changes of cytokine production according to exercise conditions such as intensity, types and working time are still unclear. In this study, we identified the sequential changes of cytokines in both skeletal muscle and plasma after …
