Comparison Of Acute Physiological Effects Between Alternating Current And Pulsed Current Electrical Muscle Stimulation, Abdulaziz A. Aldayel Nov 2010

Comparison Of Acute Physiological Effects Between Alternating Current And Pulsed Current Electrical Muscle Stimulation, Abdulaziz A. Aldayel

Theses: Doctorates and Masters

Electrical muscle stimulation (EMS) is widely used in rehabilitation and sport training, and alternating current and pulsed current EMS are commonly used. However, no systematic comparison between alternating and pulsed current EMS has been made in the previous studies. The main aim of this research was to compare acute physiological responses between the alternating and pulsed current EMS. The secondary purpose of the research was to investigate further muscle damage induced by EMS-evoked isometric contractions. Three experimental studies were conducted in the thesis project together with literature review about EMS.


Industrial Heat Stress : Using Ice Slurry Ingestion As A Practical Approach To Reducing Heat Strain In Workers, Joseph E. Maté Jan 2010

Industrial Heat Stress : Using Ice Slurry Ingestion As A Practical Approach To Reducing Heat Strain In Workers, Joseph E. Maté

Theses: Doctorates and Masters

Personnel working in industry can encounter hot and humid conditions where uncompensable heat loads are experienced; an inability to dissipate stored heat increases the risk of developing a heat illness. In order to minimise the incidence of heat illnesses, several heat stress reduction interventions have been developed which aim to allow for safe repeated bouts of exposure to high thermal heat loads. These vary from modification of the working environment, wearing of personal protective equipment designed to cool, heat stress indices and/or hydration regimens. Despite these interventions, personnel still experience heat stress related illnesses. Consequently, the overall aim of the …


Low Back Pain In Schoolgirl Rowers: Prevalence, Bio-Psycho-Social Factors And Prevention, Debra Perich Jan 2010

Low Back Pain In Schoolgirl Rowers: Prevalence, Bio-Psycho-Social Factors And Prevention, Debra Perich

Theses: Doctorates and Masters

Rowing is one of the largest participant sports on the Independent Girls‟ Schools Sporting Association (IGSSA) in Western Australia with approximately 400 participants competing every year. Rowing is an extra-curricular sport offered to girls 14 years of age and above, with these girls competing and training in both sweep and scull boats. Whilst the benefits of regular physical activity and exercise are well known, musculoskeletal problems have been documented in rowing. In particular, clinical evidence and previous research suggests that low back pain (LBP) is common in rowers. Adolescents who suffer from LBP are at an increased risk of recurrent …


Socio-Cultural Factors Influencing Male Involvement In Reproductive Health During Pregnancy, Childbirth And The Postnatal Period In Rural Districts Of Malawi, Jane Dzumbila-Namasasu Jan 2010

Socio-Cultural Factors Influencing Male Involvement In Reproductive Health During Pregnancy, Childbirth And The Postnatal Period In Rural Districts Of Malawi, Jane Dzumbila-Namasasu

Theses: Doctorates and Masters

This thesis focuses on socio cultural factors influencing male involvement in reproductive health during pregnancy, childbirth and the postnatal period in rural districts of Malawi. This research stems from my fourteen years of experience in designing and overseeing the implementation of reproductive health services in Malawi, which led me to question why men as partners/husbands are not considered in the design and implementation of such services. Men as partners/husbands bear witness to most of the reproductive health problems that women go through and they are in a position of power, making decisions for their families‟ welfare. In addition to men‟s …


How Healthy Are Hairdressers? An Investigation Of Health Problems Of Female, Western Australian Hairdressers, Mary O'Loughlin Jan 2010

How Healthy Are Hairdressers? An Investigation Of Health Problems Of Female, Western Australian Hairdressers, Mary O'Loughlin

Theses: Doctorates and Masters

Aim: Hairdressing is a common worldwide occupation which, in Australia, comprises largely of a female workforce. Hairdressers are exposed to a range of potential health hazards in their work environment. There is a lack of current research into common health problems experienced by Australian hairdressers. This study aims to investigate health issues experienced by this occupational group, to identify potential health problems that may be associated with their work and to identify concerns for future research. Methods: A review of current literature examining the health of hairdressers was conducted to ascertain areas of health concern for hairdressers. This …


Impact Of Static Stretch And Muscular Contractions On Force Production Within The Human Triceps Surae Muscle-Tendon Complex, Anthony D. Kay Jan 2010

Impact Of Static Stretch And Muscular Contractions On Force Production Within The Human Triceps Surae Muscle-Tendon Complex, Anthony D. Kay

Theses: Doctorates and Masters

Pre-performance routines commonly include stretching and intense muscular contractions in an attempt to optimise muscular performance and reduce injury risk. However, the isolated and combined effects of stretching and muscle contractions on neuromuscular performance are not well described. The aims of this research were to examine the effects of acute static stretch and intense muscular contractions on force production of the human plantarflexors and to examine possible mechanical and neuromuscular mechanisms underpinning any changes. Techniques including isokinetic dynamometry, electromyography (EMG), sonography and motion analysis were used in three studies on recreationally active human volunteers (n=20). In the first study, three …


Conceptualising Bullying In An Aboriginal Context As Reported By The Yamaji Community, To Inform The Development Of A Bullying Prevention Program That Is Culturally Sensitive To The Needs Of Aboriginal Students, Juli Coffin Jan 2010

Conceptualising Bullying In An Aboriginal Context As Reported By The Yamaji Community, To Inform The Development Of A Bullying Prevention Program That Is Culturally Sensitive To The Needs Of Aboriginal Students, Juli Coffin

Theses: Doctorates and Masters

The Solid Kids Solid Schools project aimed to capture the unheard voices of Aboriginal children and community members on the issues surrounding ‘bullying’. In an Aboriginal context bullying is different and the outcomes are different, yet mainstream programs are utilized to combat the issue. We need to know how bullying is different for Aboriginal children and young people, why it is different and what does this difference mean in terms of addressing this issue in a school and community setting? A community based steering group guided the direction of this study and the larger Solid Kids Solid Schools project. Snowball …
