Validating The Use Of The Shuttle Walking Test In Healthy Adult Women, Micheal C.M. Lim Jan 2002

Validating The Use Of The Shuttle Walking Test In Healthy Adult Women, Micheal C.M. Lim

Theses : Honours

The Shuttle Walking Test (SWT), with its externally paced characteristics, is commonly used as an objective measure of functional capacity. The reliability and validity of the SWT has been previously shown but only in patient populations. No studies have been carried out to investigate the validity of the SWT in healthy adult women. Therefore, the primary aim of this test was to determine if the SWT is a valid field measure of cardiorespiratory fitness in healthy adult women. A secondary aim was to identify if variables, such as age, body composition and habitual physical activity influence performance on the SWT. …


Examination Of The Transtheoretical Model Of Behaviour Change To Increase Physical Activity Within An Organisational Setting, Justine L. Goldspink Jan 2002

Examination Of The Transtheoretical Model Of Behaviour Change To Increase Physical Activity Within An Organisational Setting, Justine L. Goldspink

Theses : Honours

This study explored the application of Prochaska and DiClemente's (1982) transtheoretical model of behaviour change (TIM) to the area of physical activity adoption and maintenance within an organisational setting. One hundred and nine employees of the Bunbury Centrelink Call Centre participated in a six-week physical activity intervention modelled on the Take Charge Challenge (TCC) (Leonard, 2000). Based on the TIM, this program attempts to increase individual physical activity through organisational change in order to counterbalance the sedentary nature of roles undertaken by staff and to maximise physical and psychological health benefits for employees. Time (in minutes/ week) engaging in physical …


Placental Peroxisome Proliferator-Activated Receptor Gamma And Leptin Receptor In Human Pregnancy, Gwyneth H. Gladstones Jan 2002

Placental Peroxisome Proliferator-Activated Receptor Gamma And Leptin Receptor In Human Pregnancy, Gwyneth H. Gladstones

Theses : Honours

Leptin is a 16kDa peptide hormone that has recently been implicated in human reproductive processes. Like other hormones, leptin exerts its influence through its receptor. Of the three major isoforms of the receptor (OB-Ra, OB-Rb, and 0B-Re), OB-Ra (the dominant short form) has been implicated in transport processes within rat and human placentas, suggesting a role for it in implantation and pregnancy maintenance. The peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors that are a subfamily of nuclear hormone receptors. PPARs form heterodimers with another nuclear hormone receptor, RXRα, before binding to PPAR response elements (PPREs). Recently PPARϒ/RXRα heterodimers have …


Changes In Muscle Function And Motorneuron Excitability Of The Triceps Surae Following A Bout Of Fatiguing Eccentric Exercise, Mikala Pougnault Jan 2002

Changes In Muscle Function And Motorneuron Excitability Of The Triceps Surae Following A Bout Of Fatiguing Eccentric Exercise, Mikala Pougnault

Theses : Honours

A reduction in capacity of the neuromuscular system associated with exercise can occur from a wide range of physiological and psychological factors. Many researchers have investigated neural activation during exercise, or the effects of muscle damage associated with eccentric exercise, but few have studied the prolonged effects of a bout of eccentric exercise on strength and motorneuron excitability. Eleven male and female subjects (aged 20-43 years) were tested to determine the effects of a fatiguing bout of eccentric exercise upon maximal isometric plantarflexion strength, motorneuron excitability, and neural activation of the soleus (SOL) and medial gastrocnemius (MG). The exercise consisted …


General Practitioners' Attitudes To Palliative Care : A Regional Perspective, Richelle Lee-Steere Jan 2002

General Practitioners' Attitudes To Palliative Care : A Regional Perspective, Richelle Lee-Steere

Theses : Honours

The study explores regional general practitioners' attitudes to palliative care through semi- structured interviewing using a qualitative methodology. Attitudes to palliative care were examined using the general practitioners' accounts of their experiences and perceptions of caring for terminally ill patients. The participants were ten registered general practitioners located within the Greater Sunbury Division of General Practice in the South West of Western Australia. A semi-structured interview schedule containing ten open-ended questions was used to assess regional general practitioners' attitudes to palliative care. Examples of the research questions included: What are regional general practitioners' attitudes to palliative care? What supports are …


'Bringing You Up To Speed' Challenges Of A Mother Using Amphetamines : A Case Study, Derek Bilton Jan 2002

'Bringing You Up To Speed' Challenges Of A Mother Using Amphetamines : A Case Study, Derek Bilton

Theses : Honours

The purpose of the current study was to explore the challenges of parenting from the perspective of a woman who uses amphetamines. The types of parenting challenge that arise as a direct result of both intoxication and a drug using lifestyle were examined. The study also investigated the types of coping strategies that the participant adopted in meeting her parenting challenges in conjunction with the factors that aided and impeded her preferred method of responding. The study extends onto the existing literature by drawing a participant from a non-clinical setting. The participant was recruited from word of mouth field recruitment. …


Predictors Of Young Women's Attitudes Toward Sexual Health Practices, Alison G. Dougall Jan 2002

Predictors Of Young Women's Attitudes Toward Sexual Health Practices, Alison G. Dougall

Theses : Honours

The present study examined whether cognitive (beliefs), affective (emotions) and I or behavioural processes predicted young women's attitudes towards their sexual health practices. For pragmatic reasons, safer sex promotion has largely relied on the provision of factual information to promote behaviour change. Although the importance of emotional and behavioural influences has been indicated, these elements have not traditionally been included in sexual health interventions. In order to examine this issue, Zanna and Rempel's (1988) tripartite model of attitude formation was used. A convenience sample of female participants (N=98) aged 18 to 29 years was asked to rate their attitudes towards …


An Analysis Of Presentation Rates To A Paediatric Emergency Department, Andrew Hiskins Jan 2002

An Analysis Of Presentation Rates To A Paediatric Emergency Department, Andrew Hiskins

Theses : Honours

The health care industry b a very expensive one, constituting a significant proportion of the government budgets. Princess Margaret Hospital (PMH) for children is the only tertiary paediatric centre in Western Australia. PMH has over 40,000 children aged 0-16 years of age who present to the emergency department each year. PMH is one of many hospitals funded from government sources. The emergency department is a high cost area and an area with limited ability to curtail services due to financial constraints. A busy hospital will over a period of time have a constantly changing number of people presenting to the …
