Age Predicted Heart Rate Max Equations In College-Aged Students, Jessica Benchley

Honors Theses

Many clinicians use heart rate to tell how fit an individual is and how healthy they are. They can prescribe exercise based on heart rate and other medical conditions to help clients get better through exercise. Instead of running a client through a graded exercise test each time there is a problem, it would be much more effective to find an accurate equation to predict a max heart rate value and prescribe exercise using that value. The purpose of this experiment is to see which equation tends to predict the most accurate max heart after.

Effect Of Voluntary Exercise And Diet On The Unfolded Protein Response In The Brain Of Mice, Yu Ho Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The medical costs for many chronic diseases are increasing dramatically and placing a major financial burden on nations and individuals in both developed and developing countries. A number of chronic diseases, such as obesity, type 2 diabetes and some neurodegenerative diseases are all attenuated by a history of physical activity suggesting that they may be interconnected in some way. It has been suggested that cellular stress is a major factor promoting these chronic diseases.

Cellular stress occurs in a specific compartment within the cell, the endoplasmic reticulum, whose normal function is in the synthesis and folding of proteins into the …

Delayed Onset Muscle Soreness In People With Diabetes; Biomarkers And Nutritional Supplementation, Hani H. Al-Nakhli

Loma Linda University Electronic Theses, Dissertations & Projects

Exercise is important for controlling hemoglobin A1c, and maintaining proper glycemic control in people with diabetes. Exercise also increases the diabetics overall insulin sensitivity, and decreases their dependency on diabetes medication. However, people with diabetes are faced with metabolic and endothelial impairment, which could result in a prolonged sensation of muscle soreness following exercise. This would make it difficult for these people to sustain exercise regimes. Delayed-onset muscle soreness (DOMS) is a common problem in healthy individuals and in people who have diabetes. DOMS is a painful sensation experienced by individuals who have been recently inactive and then over-exercise. Yet, …

Forced-Exercise Dependent Changes In Cellular Immunity: Effects On Experimental Autoimmune Neuritis, Michael W. Calik

Dissertations (6 month embargo)

Guillain-Barré Syndrome (GBS) is a debilitating inflammatory autoimmune disease of the peripheral nervous system that is characterized by rapid-onset paraparesis with areflexia progressing to neuromuscular paralysis. The most common form of GBS observed in North America and Europe is acute inflammatory demyelinating polyneuropathy (AIDP). Enhanced infiltration of pro-inflammatory type 1 helper T (Th1) cells into peripheral nerves of AIDP patients leads to demyelination.

Increasing evidence supports exercise as an effective rehabilitative intervention. Exercise attenuates the onset and progression of autoimmune diseases. Whether exercise alters the progression of GBS remains unclear.

In this study, we determined the effects of forced-exercise on …

Investigating The Effectiveness Of Physical Activity Interventions For Older Adults, Iina E. Antikainen

Kinesiology Dissertations

Regular physical activity can help prevent chronic conditions and it is positively linked to health-related quality of life (United States Department of Health and Human Services [USDHHS], 2000). Unfortunately, many older adults do not engage in leisure time activity (USDHHS, 2000); making it important to design and test physical activity interventions for this population. The purpose of this dissertation was to review the external validity of theory-based physical activity interventions and to examine the efficacy of a mail-based physical activity intervention. The review included 54 theory-based interventions and overall the studies focused on internal rather than external validity. The hypotheses …

Factors Predicting Exercise Behavior Of Graduate Students, Bibha Gautam

Theses and Dissertations

Graduate school is often experienced as a time of increased demands/expectations resulting in heightened levels of stress due to academic work, family responsibilities, job demands, financial pressure, and other life related issues. Besides stress, graduate school also brings about significant physical inactivity due to the shift of the immediate priority to academic accomplishment. Reports of increasing prevalence of cardiovascular disease (CVD) risk factors among students highlight that this group may have particular risk not well-identified. Yet, relative risk can be reduced by lifestyle modifications, such as eating well, exercising, and stress reduction. The majority of the risk factors, to a …

Mechanisms Behind The Success Of Exercise As An Adjunct Quit Smoking Aid, Therese M. Harper

Electronic Thesis and Dissertation Repository

It is well documented that temporarily abstinent smokers who undergo an acute bout of moderate intensity exercise experience a reduction in nicotine craving and withdrawal. Conversely, available research in chronic exercise and smoking cessation does not reliably demonstrate that combining exercise with well established treatments increases smoking abstinence rates. The overall aim of this dissertation was to investigate mechanisms underlying the beneficial effects of exercise in a group of female smokers taking part in a 14 week exercise plus nicotine replacement therapy (NRT) patch programme. Determining how smokers may benefit from exercise has important implications for designing effective interventions. Three …

Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle

Masters Theses

Maximal oxygen uptake (VO_2max) is regarded as the gold standard for assessing aerobic fitness. In 1923, Hill et al. proposed that VO_2max represents the maximal ability of the body to take in and consume O₂ during strenuous exercise. Recently, however, controversy has arisen over the issue of whether a leveling off, or "plateau" in VO₂ is necessary to verify attainment of VO_2max. Purpose: To compare two different VO_2max protocols and determine if both protocols show direct evidence of an upper limit on VO₂. Methods: Nine runners (18-35 years old) completed …

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 …

Adl-Specific Versus Standard Aquatic Exercise In Older Persons, David A. Edwards

Open Access Dissertations

With aging there is a decrease in a person’s ability to perform activities of daily living (ADL) which may be most effectively addressed using training patterns that are biomechanically similar to ADL. Since aquatic exercise offers the opportunity to provide resistance with a high level of safety, the pool may afford the ideal environment for ADL-specific training in an aging population. Purpose: The purpose of this investigation was to compare a traditional aquatic exercise program (TRAD) to an aquatic program tailored to target ADL (ADLspec). Methods: Eighteen independently living individuals (68.7 + 7.5 years) were randomly assigned to a TRAD …

The Effect Of Tai Chi Exercise On Balance And Falls In Persons With Parkinson’S, Beth A. Gladfelter

Evidence-Based Practice Project Reports

Parkinson’s disease (PD) is a neurodegenerative disease that progresses to impair one’s gait and balance, often causing falls and subsequent disability. Current management of PD is aimed at treating the symptoms but is not effective in treating the underlying cause, nor does typical treatment effectively improve postural stability. Exercise can decrease symptoms of the disease and lessen disability. Providers need to find alternatives to the costly physical therapy that is prescribed to treat progressive and debilitating PD. Tai Chi (TC) has been shown to offer an enjoyable exercise routine that participants want to maintain. There is evidence to support the …

The Efficacy Of Hippocampal Stimulation In Preventing Depressive Symptoms, Timothy B. Patrick

ETD Archive

The hippocampus provides negative feedback for the Hypothalamic-Pituitary- Adrenal (HPA) axis. The HPA axis is responsible for producing a response to stressful stimuli. The hippocampus is sensitive to high levels of glucocorticoids (GCs), because of its large number of GC receptors. In times of severe stress, hippocampal function is inhibited and its control over the HPA axis is diminished, leading to hyperactivity of the adrenal glands as well as hypercortisolism, typical of depression. Long-term stress and depression can eventually lead to chronic impairments in cognitive ability, as well as structural damage in the hippocampus. Exercise and environmental enrichment stimulate significant …
