The Effects Of The Deflection Point And Shaft Mass On Swing And Launch Parameters In The Golf Swing, Christopher Joyce, Angus Burnett, Stephen Herbert 2012 Edith Cowan University

The Effects Of The Deflection Point And Shaft Mass On Swing And Launch Parameters In The Golf Swing, Christopher Joyce, Angus Burnett, Stephen Herbert

ECU Publications 2012

This study determined whether a higher dynamic deflection point (DDP) was evident when using a driver fitted with a stiff shaft of greater mass and whether between-shaft differences were evident in swing and launch parameters. Twelve elite male golfers had three shots analysed for each of two drivers fitted with “stiff” shafts of different mass (56 g and 78 g). Six swing and launch parameters were measured by a real-time launch monitor and the (DDP) was measured using a motion analysis system. Between-shaft differences were evident for the DDP at maximum, but not at ball impact. Between-shaft differences in swing ...


Swing And Launch Parameters In Approach-Iron Shots Hit With Varying Height And Trajectory In Golf, Samuel Robertson, Angus Burnett 2012 Edith Cowan University

Swing And Launch Parameters In Approach-Iron Shots Hit With Varying Height And Trajectory In Golf, Samuel Robertson, Angus Burnett

ECU Publications 2012

The first aim of this study was to determine whether relationships existed between variability of swing and launch parameters and variability in shot outcome for straight golf shots. The second aim was to determine whether differences existed for swing and launch parameters in shots intentionally played with varying height and trajectory. Elite (n=20) and high-level amateur (n=22) golfers hit; 1) five straight shots of normal height and 2) nine shots of differing height (low, normal, high) and trajectory (straight, draw, fade). Variability of club attack angle, face angle and ball spin axis was significantly associated (p


Posttraumatic Stress And Posttraumatic Growth And Their Relationship To Coping And Self-Efficacy In Northwest Australian Cyclone Communities, Julie Ann Pooley, Lynne Cohen, Moira O'Conner, Myra Taylor 2012 Edith Cowan University

Posttraumatic Stress And Posttraumatic Growth And Their Relationship To Coping And Self-Efficacy In Northwest Australian Cyclone Communities, Julie Ann Pooley, Lynne Cohen, Moira O'Conner, Myra Taylor

ECU Publications 2012

The main focus of disaster research conducted to date has been on providing insights into the negative consequences of experiencing a serious threat or adversity. The present study extends this research endeavor by investigating the positive posttrauma resiliency experiences of 512 survey respondents living in four cyclone-prone communities in Northwest Australia. The findings reveal that disaster stress is often accompanied by disaster growth and, thus, provides an alternative resilience-based way of viewing postdisaster interventions.


Inhibition Of Protein Translocation At The Endoplasmic Reticulum Promotes Activation Of The Unfolded Protein Response, Craig McKibbin, Alina Mares, Michela Piacenti, Helen Williams, Peristera Roboti, Marjo Puumalainen, Anna Callan, Karolina Lesiak-Mieczkowska, Stig Linder, Hanna Harant, Stephen High, Sabine Flitsch, Roger Whitehead, Eileithyia Swanton 2012 Edith Cowan University

Selective small-molecule inhibitors represent powerful tools for the dissection of complex biological processes. ESI (eeyarestatin I) is a novel modulator of ER (endoplasmic reticulum) function. In the present study, we show that in addition to acutely inhibiting ERAD (ER-associated degradation), ESI causes production of mislocalized polypeptides that are ubiquitinated and degraded. Unexpectedly, our results suggest that these non-translocated polypeptides promote activation of the UPR (unfolded protein response), and indeed we can recapitulate UPR activation with an alternative and quite distinct inhibitor of ER translocation. These results suggest that the accumulation of non-translocated proteins in the cytosol may represent a novel ...


The Use Of Naltrexone In Pregnancy In Opiate-Dependent Mothers, Sadie Geraghty, Carly Dixon 2012 Edith Cowan University

The Use Of Naltrexone In Pregnancy In Opiate-Dependent Mothers, Sadie Geraghty, Carly Dixon

ECU Publications 2012

There is an absence of sufficient evidence regarding naltrexone use in pregnancy due to the limited range of human studies. Naltrexone implants are being used in Western Australia as a treatment for opioid dependency, and although contraindicated for insertion during pregnancy, there are a number of women who conceive while undergoing treatment. A review of the available data revealed that naltrexone is associated with improved maternal and fetal outcomes. Extensive research into this area in the form of large, multicentre trials is required to confirm the results of the current research.


Effects Of Short-Term Training With Uncoupled Cranks In Trained Cyclists, Jack Burns, Jeremiah Peiffer, Christopher Abbiss, Greig Watson, Angus Burnett, Paul Laursen 2012 Edith Cowan University

Effects Of Short-Term Training With Uncoupled Cranks In Trained Cyclists, Jack Burns, Jeremiah Peiffer, Christopher Abbiss, Greig Watson, Angus Burnett, Paul Laursen

ECU Publications 2012

Purpose: Manufacturers of uncoupled cycling cranks claim that their use will increase economy of motion and gross efficiency. Purportedly, this occurs by altering the muscle-recruitment patterns contributing to the resistive forces occurring during the recovery phase of the pedal stroke. Uncoupled cranks use an independentclutch design by which each leg cycles independently of the other (ie, the cranks are not fixed together). However, research examining the efficacy of training with uncoupled cranks is equivocal. The purpose of this study was to determine the effect of short-term training with uncoupled cranks on the performance-related variables economy of motion, gross efficiency, maximal ...


Two Maximal Isometric Contractions Attenuate The Magnitude Of Eccentric Exercise-Induced Muscle Damage, Hsin-lian Chen, Kazunori Nosaka, Alan Pearce, Trevor C Chen 2012 Edith Cowan University

Two Maximal Isometric Contractions Attenuate The Magnitude Of Eccentric Exercise-Induced Muscle Damage, Hsin-Lian Chen, Kazunori Nosaka, Alan Pearce, Trevor C Chen

ECU Publications 2012

This study investigated whether maximal voluntary isometric contractions (MVC-ISO) would attenuate the magnitude of eccentric exercise-induced muscle damage. Young untrained men were placed into one of the two experimental groups or one control group (n = 13 per group). Subjects in the experimental groups performed either two or 10 MVC-ISO of the elbow flexors at a long muscle length (20° flexion) 2 days prior to 30 maximal isokinetic eccentric contractions of the elbow flexors. Subjects in the control group performed the eccentric contractions without MVC-ISO. No significant changes in maximal voluntary concentric contraction peak torque, peak torque angle, range of motion ...


Strength Gains: Block Versus Daily Undulating Periodization Weight Training Among Track And Field Athletes, Keith Painter, Guy Haff, Michael Ramsey, Jeff McBride, Travise Triplett, William Sands, Hugh Lamont, Margaret Stone, Michael Stone 2012 Edith Cowan University

Strength Gains: Block Versus Daily Undulating Periodization Weight Training Among Track And Field Athletes, Keith Painter, Guy Haff, Michael Ramsey, Jeff Mcbride, Travise Triplett, William Sands, Hugh Lamont, Margaret Stone, Michael Stone

ECU Publications 2012

Recently, the comparison of "periodized" strength training methods has been a focus of both exercise and sport science. Daily undulating periodization (DUP), using daily alterations in repetitions, has been developed and touted as a superior method of training, while block forms of programming for periodization have been questioned. Therefore, the purpose of this study is to compare block to DUP in Division I track and field athletes. Thirty-one athletes were assigned to either a 10-wk block or DUP training group in which sex, year, and event were matched. Over the course of the study, there were 4 testing sessions, which ...

ECU Publications 2012

This investigation describes the sprint performances of the highest internationally ranked professional male road sprint cyclist during the 2008-2011 Grand Tours. Sprint stages were classified as won, lost, or dropped from the front bunch before the sprint. Thirty-one stages were video-analyzed for average speed of the last km, sprint duration, position in the bunch, and number of teammates at 60, 30, and 15 s remaining. Race distance, total elevation gain (TEG), and average speed of 45 stages were determined. Head-to-head performances against the 2nd-5th most successful professional sprint cyclists were also reviewed. In the 52 Grand Tour sprint stages the ...


Lower Extremity Kinematics And Kinetics When Landing From Unloaded And Loaded Jumps, Ina Janssen, Jeremy Sheppard, Andrew Dingley, Dale Chapman, Wayne Spratford 2012 Edith Cowan University

Lower Extremity Kinematics And Kinetics When Landing From Unloaded And Loaded Jumps, Ina Janssen, Jeremy Sheppard, Andrew Dingley, Dale Chapman, Wayne Spratford

ECU Publications 2012

Countermovement jumps loaded with a weighted vest are often used for the training of lower body power to improve jump performance. However, it is currently unknown how this added load affects the lower extremity kinematics and kinetics, in particular whether this results in an increased injury risk. Therefore, the purpose of this investigation was to determine how lower extremity kinematics and kinetics during landing are affected by loaded jumps as demonstrated in a volleyball block jump landing. Ten elite male volleyball players performed block jump landings in an unloaded and loaded (9.89 kg) condition. Kinematic and kinetic landing data ...


Effects Of Two Contrast Training Programs On Jump Performance In Rugby Union Players During A Competition Phase, C K Argus, N D Gill, J W Keogh, Michael Mcguigan, W G Hopkins 2012 Edith Cowan University

Effects Of Two Contrast Training Programs On Jump Performance In Rugby Union Players During A Competition Phase, C K Argus, N D Gill, J W Keogh, Michael Mcguigan, W G Hopkins

ECU Publications 2012

Purpose: There is little literature comparing contrast training programs typically performed by team-sport athletes within a competitive phase. We compared the effects of two contrast training programs on a range of measures in high-level rugby union players during the competition season. Methods: The programs consisted of a higher volume-load (strength-power) or lower volume-load (speed-power) resistance training; each included a tapering of loading (higher force early in the week, higher velocity later in the week) and was performed twice a week for 4 wk. Eighteen players were assessed for peak power during a bodyweight countermovement jump (BWCMJ), bodyweight squat jump (BWSJ ...

Multiple Effects Of Physical Activity On Molecular And Cognitive Signs Of Brain Aging: Can Exercise Slow Neurodegeneration And Delay Alzheimer's Disease?, Belinda Brown, J J Peiffer, Ralph Martins 2012 Edith Cowan University

Multiple Effects Of Physical Activity On Molecular And Cognitive Signs Of Brain Aging: Can Exercise Slow Neurodegeneration And Delay Alzheimer's Disease?, Belinda Brown, J J Peiffer, Ralph Martins

ECU Publications 2012

Western countries are experiencing aging populations and increased longevity; thus, the incidence of dementia and Alzheimer's disease (AD) in these countries is projected to soar. In the absence of a therapeutic drug, non-pharmacological preventative approaches are being investigated. One of these approaches is regular participation in physical activity or exercise. This paper reviews studies that have explored the relationship between physical activity and cognitive function, cognitive decline, AD/dementia risk and AD-associated biomarkers and processes. There is now strong evidence that links regular physical activity or exercise to higher cognitive function, decreased cognitive decline and reduced risk of AD ...


The Hippo Pathway Member Yap Plays A Key Role In Influencing Fate Decisions In Muscle Satellite Cells, Robert Judson, Annie Tremblay, Paul Knopp, Robert White, Roby Urcia, Cosimo De Bari, Peter Zammit, Fernando Camargo, Henning Wackerhage 2012 Edith Cowan University

The Hippo Pathway Member Yap Plays A Key Role In Influencing Fate Decisions In Muscle Satellite Cells, Robert Judson, Annie Tremblay, Paul Knopp, Robert White, Roby Urcia, Cosimo De Bari, Peter Zammit, Fernando Camargo, Henning Wackerhage

ECU Publications 2012

Satellite cells are the resident stem cells of skeletal muscle. Mitotically quiescent in mature muscle, they can be activated to proliferate and generate myoblasts to supply further myonuclei to hypertrophying or regenerating muscle fibres, or self-renew to maintain the resident stem cell pool. Here, we identify the transcriptional co-factor Yap as a novel regulator of satellite cell fate decisions. Yap expression increases during satellite cell activation and Yap remains highly expressed until after the differentiation versus self-renewal decision is made. Constitutive expression of Yap maintains Pax7+ and MyoD+ satellite cells and satellite cell-derived myoblasts, promotes proliferation but prevents differentiation. In ...


A Phenomenological Exploration Of The Childfree Choice In A Sample Of Australian Women, Joanne Doyle, Julie Ann Pooley, Lauren Breen 2012 Edith Cowan University

A Phenomenological Exploration Of The Childfree Choice In A Sample Of Australian Women, Joanne Doyle, Julie Ann Pooley, Lauren Breen

ECU Publications 2012

Choosing not to have children is considered a deviation from cultural norms, particularly the dominant pronatalist discourse; this is especially so for women. However, little research has documented the experience of Australian women who have consciously chosen to remain childless. Ten voluntarily childfree women participated in unstructured interviews about their choice and its ramifications. The data analysis revealed three broad themes – the experiences and processes of making the choice; the ongoing effects of their choice, ranging from support and acceptance to pressure and discrimination; and no regret as the women described engaging in meaningful, generative activities that contributed to society.


Crime Prevention: The Role Of Individual Resilience Within The Family., Catherine Ferguson, Craig Harms, Julie Ann Pooley, Lynne Cohen, Stuart Tomlinson 2012 Edith Cowan University

Crime Prevention: The Role Of Individual Resilience Within The Family., Catherine Ferguson, Craig Harms, Julie Ann Pooley, Lynne Cohen, Stuart Tomlinson

ECU Publications 2012

Resilience is context dependent but for resilience to be present, two elements must co-occur: adversity (i.e., high-risk situation/threat) and successful adaptation/competence. An understanding of resilience is important for professionals dealing with at-risk families. This exploratory research investigated how individuals caring for a family member with a mental illness adapted to the role of carer or supporter. Fifteen participants mostly aged 50 years or more were interviewed. Content analysis was used to develop themes from the interview transcripts. Seven themes were elicited from the data. Three of these fit with existing knowledge about challenges faced by offenders’ families ...


Blood-Brain Barrier Abnormalities Caused By Hiv-1 Gp120: Mechanistic And Therapeutic Implications., Jean-Pierre Louboutin, David S Strayer 2012 Department of Pathology, Anatomy and Cell Biology, Thomas Jefferson University

Blood-Brain Barrier Abnormalities Caused By Hiv-1 Gp120: Mechanistic And Therapeutic Implications., Jean-Pierre Louboutin, David S Strayer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The blood-brain barrier (BBB) is compromised in many systemic and CNS diseases, including HIV-1 infection of the brain. We studied BBB disruption caused by HIV-1 envelope glycoprotein 120 (gp120) as a model. Exposure to gp120, whether acute [by direct intra-caudate-putamen (CP) injection] or chronic [using SV(gp120), an experimental model of ongoing production of gp120] disrupted the BBB, and led to leakage of vascular contents. Gp120 was directly toxic to brain endothelial cells. Abnormalities of the BBB reflect the activity of matrix metalloproteinases (MMPs). These target laminin and attack the tight junctions between endothelial cells and BBB basal laminae. MMP-2 ...

The Influence Of Federally Qualified Health Centers On Selected Ambulatory Care Sensitive Conditions In Georgia, Mary W. King Mathis 2012 Georgia Southern University

The Influence Of Federally Qualified Health Centers On Selected Ambulatory Care Sensitive Conditions In Georgia, Mary W. King Mathis

Electronic Theses & Dissertations

Author's Abstract: Ambulatory care sensitive conditions (ACSCs) resulting in hospitalizations make up a substantial proportion of health care costs, but should not because these conditions are manageable in quality primary care settings that promote prevention in an effort to avoid exacerbations that can lead to hospitalization. The use of emergency departments (EDs) as a safety net for ACSCs has increased the burden on hospitals because patients who do not regularly utilize primary care often resort to the use of EDs for treatment of ACSCs. Federally qualified health centers (FQHCs) are designed to provide consistent, high-quality primary care to all ...
