Bilateral And Unilateral Resistance Training And Athletic Performance, Brendyn B. Appleby

Theses: Doctorates and Masters

Specificity is a key programming principle for optimal transfer of physiological adaptation of training to improved athletic performance. In resistance training, it has long been identified that the closer the mechanical specificity between the training exercise and outcome performance, the greater the transfer of improved capacity. Bilateral resistance exercises are predominately prescribed for the development of maximum strength and are well demonstrated to enhance athletic performance. However, unilateral exercises appear to demonstrate greater specificity to movements such as running and change of direction as these movements are predominantly single leg actions. Nonetheless, the unstable nature and comparatively lower magnitude of …

Students encounter difficulties in obtaining opportunities to practice their skills and develop competence when on …

A Qualitative Study Into The Communication Surrounding The Initiation And Withdrawal Of Non-Invasive Ventilation (Niv) In People With Motor Neurone Disease, Charlotte Chapman

Theses: Doctorates and Masters

Introduction

Motor neurone disease (MND) is a degenerative disease that adversely affects the nervous system and muscular control. Eventually respiratory muscles weaken, causing breathing, communication and swallowing difficulties, and ultimately, respiratory failure and death. Improved quality of life and potentially a short extension of life can be provided with non-invasive ventilation (NIV), which is offered to people with MND when symptoms of respiratory distress become evident.

It is recommended that end-of-life communication, encompassing the benefits and burdens of symptom-relieving interventions (NIV and percutaneous gastrostomy tube to assist with nutrition), NIV withdrawal (proposed when continued use is considered futile) and other …

Velocity-Based Training: Monitoring, Implementation And Effects On Strength And Power, Henry G. Banyard

Theses: Doctorates and Masters

Traditionally, resistance training has been prescribed using percent-based training (PBT) methods that use the loads relative to a maximal load lifted for one repetition (1RM). However, PBT does not take into account possible day-to-day fluctuations in performance that may occur from physical or psychological stressors. One approach to address this limitation is to monitor velocity changes during resistance training, based on research showing that declines in velocity are highly correlated with fatigue. Therefore, velocity-based training (VBT) methods are proposed to provide a more objective method to modify resistance training sessions based on individual differences in day-to-day performance and the rate …

Heat Exposure And Adaptation Strategies Of Outdoor Informal Sector Workers In Urban Bulawayo - Zimbabwe, Bigboy Ngwenya

Theses: Doctorates and Masters

Ambient temperatures have risen over the past few decades and are expected to increase even further due to climate change impacts. Extreme temperatures, accompanied by high humidity levels, will exacerbate occupational heat stress, heat related illnesses and mortality amongst vulnerable groups, particularly among outdoor workers in developing countries in the tropics. In Bulawayo, Zimbabwe, a large portion of the population work outdoors in the informal sector as street vendors (hawkers) due to a lack of employment opportunities. These hawkers spend long hours in the sun or under makeshift sheds with poorly developed adaptation strategies, and no access to cooling systems …

A Public Health Perspective Of The Higher Education Experiences Of Women Studying Nursing: A Hermeneutic Inquiry Into Commencement And Progression, Lesley Jane Andrew

Theses: Doctorates and Masters

While student retention is a central goal across higher education, the projected shortage in the Australian health workforce has intensified its importance to undergraduate nursing.

Nursing degrees attract a higher proportion of mature-age women students than ever before. More are therefore beginning university at life stage characterised by marriage (or co-habitation) and traditional family structures. Nursing retention strategies require an understanding of the unique university experiences of these women, however, this is missing in the nursing literature. This study is the first to explore the experiences of these women students, doing so from the perspective of Bachelor of Science (Nursing) …

The Manifestations Of Fatigue In Amateur Boxing Performance, Emily C. Dunn

Theses: Doctorates and Masters

A subjective method of judgment, the “Ten Point Must-System” (TPMS), was introduced into amateur boxing in 2013. To be successful, boxers must deliver forceful punches and exert dominance over an opponent. There has been limited research examining the strategies used by boxers to win fights under the TPMS and whether these strategies induce fatigue that is sufficient to significantly affect punch force. The overall objective of the five studies contained in this thesis was to describe, in relation to fatigue, the performance characteristics of male amateur boxers under the TPMS, and improve our understanding of the physical characteristics associated with …

Moving On After Critical Incidents In Health Care. Second Victims: A Qualitative Study Of The Experiences Of Nurses And Midwives, Melanie Buhlmann

Theses: Doctorates and Masters

Aims: The aims of this study were to gain a deeper understanding of the experiences of nurses and midwives who have been involved in a critical incident in a non-critical care area and to explore how they have ‘moved-on’ from the event.

Background: It is irrefutable that health care is intrinsically risk-laden and perceived to be personally and professionally demanding for those who are employed within it. The term ‘second victim’ has been assigned to health care professionals who experienced emotional distress as a result of their involvement in critical incidents. Despite the recognition that critical incidents contribute to workrelated …

Factors Affecting The Survival And Implantation Of Human Blastocysts Following Vitrification, Hamish Barblett

Theses: Doctorates and Masters

The increased cell numbers, presence of the blastocoel and rapid cell re-organisation have required the development of specific survival criteria post warm to effectively select the most viable blastocyst for transfer. Pre-freeze blastocyst expansion and post warm re-expansion have been shown to contribute significantly to the chances of an implantation and subsequent live birth. The aim of this study was to explore factors that influence the outcome of blastocyst transfers after vitrification and warming, and hopefully improve outcomes by further applying improvements in future cycles. Variables from 8 years of vitrified/warmed blastocysts were retrospectively compiled and analysed to determine the …

Linking Patient Safety To Clinical Practice: The Insight Of New Graduate Registered Nurses, Melanie Murray

Theses: Doctorates and Masters

New graduate registered nurses’ (NGRNs) transition to practice with limited clinical experiences and skills. The related anxiety and stress predispose new graduate nurses to increased risk of contributing to preventable errors or adverse events. This risk, together with the new graduate’s fledgling ability to manage clinical deterioration, potentially compromises quality and safety of patient outcomes.

A longitudinal mixed methods design was used to develop an understanding of new graduate registered nurses’ patient safety knowledge and actions within the first year of nursing registration and offer important insights into NGRNs’ transition with a patient safety focus. New graduate registered nurses employed …

Theses: Doctorates and Masters

Background

Aphasia is a neurological condition that affects the expression and/or comprehension of language and can have considerable impact on a person’s quality of life. Treatment for aphasia from speech language pathologists is effective. However, more information is needed on the nature of effective intervention including consideration for what therapy is provided, when it is commenced and how it is delivered. Treatment fidelity is concerned with ensuring research treatment protocols are implemented as they were intended, which assists in uncovering the specifics of how and why treatments work. When treatment fidelity is investigated thoroughly, researchers and research consumers can be …

The Placenta And Cardiovascular Disease: A Meta-Analysis, Ruben Phillips

Theses: Doctorates and Masters

The uterine environment in which a fetus grows and develops is now recognised as a risk factor for the development of adult diseases such as cardiovascular disease (CVD). A fetus relies on the nutrients and conditions delivered via the placenta, and as such the placenta plays a vital role in the establishment and maintenance of appropriate uterine conditions. Unfavourable uterine conditions such as an inadequate resource flow from the placenta can lead to diminished growth of the fetus and may ultimately result in both short and long-term increases in risk of CVD for the baby. This has been demonstrated in …

The Application Of Maximal Mean And Critical Speed And Metabolic Powers For The Quantification Of External Load In Soccer, Cameron Nicholas Lord

Theses: Doctorates and Masters

In Association football, often referred to as “soccer”, competitive match play is typically known to represent the greatest physical demand that players experience. The demands associated with match running performance may impact training outcomes and injury risk. As a result, practitioners evaluate these demands to ensure that performance is optimised. To assist in this process, global positioning systems (GPS) are typically used to quantify displacement variables and, more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to …

Social Impacts Of Climate Change And Occupational Heat Stress And Adaptation Strategies Of Mining Workers In Ghana, Victor Fannam Nunfam

Theses: Doctorates and Masters

Excessive heat exposure due to rising temperatures associated with climate change adversely affects workers’ health, safety, productivity, and psychosocial well-being in occupational settings. In the hot and tropical regions of developing countries, long hours of physically demanding work, coupled with inadequate adaptation policies to climate change, increases the occurrence of heat-related illnesses and injuries, and contributes to the loss of productive capacity, poor decision making, and other negative effects on the social well-being of workers.

Based on the theories of social impact assessment, risk assessment, adaptation and resilience planning, this study assesses the social impacts of climate change and occupational …

Analysis Of Perceptual-Motor Calibration Processes In Indoor Climbing, Andrew Stephen Walsh

Theses: Doctorates and Masters

This research programme examines how people perceive maximal reach-and grasp-ness in climbing, and as such these questions will be limited to climbing.

Is experienced gained from performing daily submaximal reaching sufficient for the accurate perception of maximal horizontal reaching affordances in rock climbing?

How is perception of maximal horizontal boundary of reach-and grasp-ness affected by: hold size, body position, additional load, or fatigue.

How will inducing fatigue affect how a participant calibrates distance and their movement economy?

The Influence Of Barbell And Body Position On Force-Time Characteristics In The Isometric Mid-Thigh Pull, Stuart Nathan Guppy

Theses: Doctorates and Masters

Publication 1: The Isometric Mid-Thigh Pull: A Review and Methodology – Part 1 Isometric tests are commonly used to monitor physical qualities that underpin athletic performance. As single-joint laboratory-based tests display poor relationships to the multi-joint movements found in sport, multi-joint isometric tests like the isometric midthigh pull (IMTP) are commonly used instead. Force-time characteristics in these multijoint tests typically display stronger relationships to dynamic performance, particularly in the case of the isometric mid-thigh pull. As such this review focuses on the relationships between force-time characteristics in the IMTP and dynamic athletic performance.

Publication 2: The Isometric Mid-Thigh Pull: A …

An Exploration Of The Critical Success Factors Associated With Implementing A Public Health Plan In Local Governments Within Western Australia, Anne Polley

Theses: Doctorates and Masters

Public Health planning in local governments in Western Australia (WA) is a relatively new approach to addressing local health needs. The Western Australian Public Health Act came into effect in 2016. The Public Health Act 2016 encompasses a range of legislative requirements, some of which include the development of Local Public Health Plans. A range of roles within the local government workforce therefore are likely to require support to plan and implement Public Health Plans, which in the past have not directly been a component of their role. There is limited understanding and evidence of the barriers and enablers that …
