Validation Of Non-Invasive Co2 Tolerance Field Test, Joshua T. Murphey
Boise State University Theses and Dissertations
INTRODUCTION: Breathwork, or the specific act of controlling breathing to elicit a desired outcome, is not only a potential way to improve one’s mental well-being but also to alter adaptative responses through gas exchange at the capillary level. Increasing tolerance to carbon dioxide (CO2) has been positively correlated with improvement in athletic performance and reduction of stress and anxiety. However, there does not exist a validated non-invasive test to accurately measure one’s tolerance to CO2. PURPOSE: The purpose of this study was to validate the only currently known CO2 tolerance (CO2T) field test …

Introduction
The United Kingdom and World Health Organization recently changed their youth physical activity (PA) guidelines from 60 min of moderate- to vigorous-intensity PA (MVPA) every day, to an average of 60 min of MVPA per day, over a week. The changes are based on expert opinion due to insufficient evidence comparing health outcomes associated with different guideline definitions. This study used the International Children’s Accelerometry Database to compare approaches to calculating youth PA compliance and associations with health indicators.
Methods
Cross-sectional accelerometer data (n = 21,612, 5–18 yr) were used to examine compliance with four guideline definitions: daily …

There is a strong link between physical activity and health. Historically, large-scale epidemiological studies have used self-report surveys to capture physical activity measures (eg, type and intensity). In the past 20–30 years, large cohort studies have increasingly adopted devices, such as pedometers, accelerometers, and consumer-marketed activity trackers, to measure physical activity. Device-based physical activity measures alleviate some limitations of self-reporting by increasing measurement objectivity and accuracy. Additionally, device-based measures often show stronger associations with health outcomes than do self-reported measures, showcasing their value in understanding how physical activity affects health. Unlike self-report, device-based measures can capture steps, which are easily …

How Exercise Affects The Musculoskeletal System In The Biological Sexes: A Literature Review, Lauren Connolly
How Exercise Affects The Musculoskeletal System In The Biological Sexes: A Literature Review, Lauren Connolly
Honors Program Theses
Exercise has countless benefits for the human body. Physical activity increases overall health and reduces the risk of developing many chronic diseases. While the entire body is impacted by exercise, the musculoskeletal system is perhaps targeted most directly. Muscle contraction is required to complete any form of exercise, which helps build muscle mass and consequently strengthens bones. The physiology of musculoskeletal growth after exercise is the same for all individuals. However, the magnitude of this growth is not the same for men and women. Men have a profound ability to gain muscle mass that most women are not capable of …
The Role Of Ovarian Hormones In Appetite-Regulation: Examining The Post-Exercise Appetite Response In Pre- Vs Post-Menopausal Females, Jessica A.L. Tucker
The Role Of Ovarian Hormones In Appetite-Regulation: Examining The Post-Exercise Appetite Response In Pre- Vs Post-Menopausal Females, Jessica A.L. Tucker
Theses and Dissertations (Comprehensive)
INTRODUCTION: Appetite fluctuates across the menstrual cycle, suggesting ovarian hormones are involved in the regulation of appetite hormones and energy intake. Exercise is another regulator of appetite with higher intensity exercise generating a greater and more consistent suppression. Considering there is limited evidence investigating the role of ovarian hormones in appetite regulation, menopause represents a stage of life where ovarian function declines, thus providing an opportunity to further explore the role of ovarian hormones in the appetite-regulatory response to exercise. PURPOSE: To examine the role of ovarian hormones on appetite-regulating hormones in pre- and post-menopausal females following a …

Cancer is the second leading cause of death, with about approximately 1.9 million Americans being diagnosed each year. Yet, it has high survival rates with the help of advancing treatments like radiation therapy. Cancer patients and survivors are contingent on experiencing a decline in physical functioning, quality of life, and physiological parameters. Treatment is effective and can prolong life expectancy but can be deleterious to a patient’s health. Parallel with cancer's impact on Americans is cardiovascular disease. Cardiovascular disease is responsible for 1 in 4 deaths. The development of cardiovascular disease is not spread accordantly among all ethnicities. Hispanics are …

International Journal of Exercise Science
International Journal of Exercise Science 14(1): 211-221, 2021. Moderate angle cutting maneuvers (between 45º and 90º) are common and essential performance skills for success in multidirectional sports. Research addresses the injury risks of cutting but few studies have attempted to quantify the performance of the cut itself. PURPOSE: To identify any anthropometric, kinematic, and/or kinetic markers of a high-performance cut so they may be taught and lead to more effective training. METHODS: Ten college-aged male athletes (mass 73.97 ± 8.77kg, height 1.81 ± 0.07m) and ten non-athletes (mass 87.37 ± 13.93kg, height 1.85 ± 0.04m) completed five moderate angle cutting …

Muscle Blood Flow Is Independent Of Conduit Artery Diameter Following Prior Vasodilation In Males, Timothy R. Rotarius, Jakob D. Lauver, John R. Thistlethwaite, Barry W. Scheuermann
Kinesiology
At the onset of exercise in humans, muscle blood flow (MBF) increases to a new steady-state that closely matches the metabolic demand of exercise. This increase has been attributed to “contraction-induced vasodilation,” comprised of the skeletal muscle pump and rapid vasodilatory mechanisms. While most research in this area has focused on forearm blood flow (FBF) and vascular conductance, it is possible that separating FBF into diameter and blood velocity can provide more useful information on MBF regulation downstream of the conduit artery. Therefore, we attempted to dissociate the matching of oxygen delivery and oxygen demand by administering glyceryl tri-nitrate (GTN) …

The Influence Of Cerebellar Transcranial Direct Current Stimulation On Motor Function In Parkinson’S Disease, Lidio Lima De Albuquerque
UNLV Theses, Dissertations, Professional Papers, and Capstones
Parkinson's disease (PD) is the most common movement disorder and the second most common neurodegenerative disorder. PD is characterized by dopaminergic cell loss in the substantia nigra pars compacta, which leads to a reduction in dopamine in the striatum. These physiological mechanisms lead to a number of motor impairments such as bradykinesia, rigidity, tremor, and postural instability that severely limit the ability of individuals with PD to perform many essential daily living activities. Although current pharmacological, surgical, and physical exercise treatment approaches are valuable they are either only mildly effective, expensive, or associated with a variety of side effects. Therefore, …

Human physiological signals are inherently rhythmic and have a hallmark feature in that even distant intrasignal measurements are related to each other. This relationship is termed long-range correlation and has been recognized as an indicator of the optimal state of the observed physiological systems, among which the locomotor system. Loss of long-range correlations has been found as a result of aging as well as disease, which can be evaluated with detrended fluctuation analysis (DFA). Recently, DFA and the scaling exponent α have been employed for understanding the degeneration of temporal regulation of human walking biorhythms in, for example, Parkinson disease …

The Effect Of Pre-Workout Supplementation On Fitness Assessment Tests, Kassidy Davis
Honors Theses
Research regarding the benefits and detriments of Pre-workout supplement has gradually increased since its popularity arose in the early 1980’s. There have been a number of studies on its effects on human physiology during a workout; however, there are few studies regarding Preworkout supplement during fitness assessment tests. Therefore, further insights concerning Preworkout supplement and fitness testing is needed. Pre-workout supplement is taken prior to a training session and has been shown to enhance a workout by increasing aspects such as focus, reaction time, stamina, and power. This could be viewed as solely a psychological enhancement than an actual physical …
