Controlling Myosin’S Function Via Interactions Between The Substrate And The Active Site, Mike K. Woodward
Controlling Myosin’S Function Via Interactions Between The Substrate And The Active Site, Mike K. Woodward
Doctoral Dissertations
Molecular motors, such as myosin, have evolved to transduce chemical energy from ATP into mechanical work to drive essential cellular processes, from muscle contraction to vesicular transport. Dysfunction in these motors is a root cause of many pathologies necessitating the application of intrinsic control over molecular motor function. We hypothesized that altering the myosin’s energy substrate via minor positional changes to the triphosphate portion of the molecule will allow us to control the protein and affect its in vitro function. We utilized positional isomers of a synthetic non-nucleoside triphosphate, azobenzene triphosphate, and assessed whether myosin’s force- and motion-generating capacity could …
An Evaluation Of A Mobile Health-Health Action Process Approach Intervention To Reduce Sedentary Behaviour And Stress In Adult Office Workers - Randomized Controlled Trial, Brett Carter
Electronic Thesis and Dissertation Repository
Sedentary behaviour (SB) has been linked with a variety of negative health consequences which can be diminished by increasing frequency of breaks. The Health Action Process Approach (HAPA) is an effective behaviour change model for reducing SB in adult office workers. The objective of this study was to evaluate a mobile health HAPA-based sedentary behaviour intervention in office workers. Fifty-three participants (Mean age 40.62, 79.2% women) were randomized into a treatment group or a no-contact control group in a four-week, two-arm parallel randomized controlled trial. All SB outcomes were assessed from Baseline to Week 4, perceived stress was measured at …
A Biomechanical Approach To Prevent Falls In Ergonomic Settings, Sachini Kodithuwakku Arachchige
A Biomechanical Approach To Prevent Falls In Ergonomic Settings, Sachini Kodithuwakku Arachchige
Theses and Dissertations
Introduction: Fall-related injuries are exceptionally prevalent in occupational settings. While endangering the workers’ health, falls cause poor productivity and increased economic burden in the workplace. Hence, identifying these threats and training workers to achieve proper postural control is crucial. Purpose: Study 1: To investigate the ankle joint kinematics in unexpected and expected trip responses during single-tasking (ST), dual-tasking (DT), and triple-tasking (TT), before and after a physically fatiguing exercise. Study 2: To investigate the impact of virtual heights, DT, and training on static postural stability and cognitive processing. Methods: Study 1: Twenty collegiate volunteers (10 males and females, one left …
“Sometimes The People Giving The Care Get A Little Overlooked”: Athletic Trainers’ Personal Use Of Psychosocial Strategies And Interactions With Mental Performance Consultants, Alexander Bianco
Doctoral Dissertations
In National Collegiate Athletic Association Division I (NCAA DI) athletic departments, athletic trainers (ATs) must navigate an array of stressors in the workplace, and are effectively performers themselves (Estock & Simon, 2018, Mazerolle et al., 2013). While ample research has been conducted on the stressors that ATs experience (see Oglesby et al., 2020) there has been limited work surrounding how ATs can best navigate this environment. Therefore, the purpose of the current investigation was to explore NCAA DI ATs’ perceptions of and experiences with the personal use of psychosocial strategies and sport psychology services to manage their stress, improve their …

Relationship Of Eccentric Strength And Forward Perturbation Restabilization After Foot Contact, Leandra K. Ashworth
Relationship Of Eccentric Strength And Forward Perturbation Restabilization After Foot Contact, Leandra K. Ashworth
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Background: Forward falls are the most common fall direction and pose safety concerns for adults. To prevent forward falls, compensatory steps, and change-in-support reactions (e.g., foot contact) are critical for restabilizing center of mass after unpredictable, balance disturbances. Multi-joint, lower limb eccentric and isometric strength may provide additional insight on foot contact responses after a forward, temporally unpredictable perturbation. Multi-joint, eccentric muscular contractions have been found to result in significant neuromuscular adaptations (e.g., hypertrophy and muscular strength) and have higher retention capabilities than concentric contractions. Due to the importance of muscular strength in balance recovery, eccentric muscular strength could provide …
Student Sleep Patterns When Exposed To Mindfulness Reminders, Zeyanna Dhalla
Student Sleep Patterns When Exposed To Mindfulness Reminders, Zeyanna Dhalla
Undergraduate Honors Theses
University students are plagued with increased levels of stress and anxiety which can lead to poor sleep quality and quantity. Breathing techniques have demonstrated counteractive effects to the chronic stresses that the population encounters on an everyday basis. Wearable technology, such as Apple Watches, contain a mindfulness feature that encourages its users to pause throughout the day and engage in mindfulness through resonant breathing. Wearable technology has become increasingly accessible and is also growing in accuracy to measure different biometrics such as sleep quality and quantity. The purpose of the present study was to examine if the mindfulness reminders initiated …
Understanding Para Athlete Development: An Examination Of Para Swimming, Darda J. Sales
Understanding Para Athlete Development: An Examination Of Para Swimming, Darda J. Sales
Electronic Thesis and Dissertation Repository
Most competitively spirited individuals who engage in sport, we call them athletes, are striving to be the best they can be at their chosen discipline. To help athletes achieve their goals, several athlete development models (Côté, 1999, Gulbin et al., 2013, Higgs et al., 2019) have been produced to help coaches and sport administrators best support, and guide an athlete to achieve their optimum performance. While it has been recognized that there is contextual uniqueness to the para athlete development experience (Huetzler et al., 2016) and that there are nuances to the para athlete development experience that need to be …

Examining The Impact Of Financial Incentive Removal On Physical Activity: A Quasi-Experimental Study Of 584,760 Mobile Health Application Users, Sean Kevin Spilsbury
Electronic Thesis and Dissertation Repository
BACKGROUND: Government interest in using financial incentives (FIs) to stimulate physical activity (PA) is increasing. The cost of longer-term incentive interventions may be prohibitive, however. PURPOSE: To examine the impact of FI withdrawal on PA. METHODS: A 25-week retrospective pre-post quasi-experimental study was conducted with users of a FI-based mHealth app. Users from three Canadian provinces were included. Daily FI were removed in Ontario (ON; intervention) but not British Columbia (BC) and Newfoundland and Labrador (NL; control). Simple linear regression models were used to examine weekly mean daily step count after FI withdrawal. RESULTS: The total sample included 584,760 users …
The Benefits Of Therapeutic Ultrasound For Improving Recovery Of Collegiate Soccer Players In Between Friday And Sunday Matches, Adam Armijo
Regis University Student Publications (comprehensive collection)
Collegiate soccer athletes face physical and physiological stressors during match play that can lead to ailments such as inflammation, muscle soreness, decreased range of motion, and skeletal muscle damage. Through the use of evidence-based studies coaches, trainers, and collegiate soccer athletes can determine best practices for optimized recovery in a collegiate soccer setting. One of the lacking supplemental recovery modalities in collegiate soccer is therapeutic ultrasound. Therapeutic ultrasound is a machine that utilizes vibration and thermal effects to help decrease skeletal muscular damage, reduce soreness of skeletal muscles, improve blood flow, and increase relaxation of the muscles. Therapeutic ultrasound in …
Beginnings, Elizabeth Becker
Beginnings, Elizabeth Becker
Dance (MFA) Theses
Researcher Elizabeth Becker uses personal experiences of pregnancy alongside scholarly research on the developmental movement patterns of the human embryo, fetus, and newborn’s first year of life to explore the multiplicity of these movement patterns within and outside the womb. Becker explores the relationship between the fertilization, germinal, embryonic, and fetal stages in relation to a newborn and its mother. These movement patterns within the beginning stages of life are valuable to research because they simulate neurodevelopmental patterns, which help wire the central nervous system in early childhood. These movements also help lay the foundation for sensory-motor development and life-long …
