Transcranial Direct Current Stimulation And Sports Performance, Dylan J. Edwards, Mar Cortes, Susan Wortman-Jutt, David Putrino, Marom Bikson, Gary Thickbroom, Alvaro Pascual-Leone

Research outputs 2014 to 2021

The application of transcranial direct current stimulation (tDCS) hasmoved fromthe laboratory to the wider community. This form of non-invasive brain stimulation has been shown in a number of controlled animal and human experiments, over nearly five decades, to modulate brain physiology, cognitive functions, and behavior. While its effects are variable across and within individuals, it is not unreasonable to state that tDCS harbors the potential to enhance executive and physical human performance. In a society increasingly driven to succeed with less effort, performance enhancement with an intervention that has an excellent safety record, is well tolerated, relatively inexpensive and readily …

The relationship between body-mass index (BMI) and Alzheimeŕs disease (AD) has been extensively investigated. However, BMI alterations in preclinical individuals with autosomal dominant AD (ADAD) have not yet been investigated. We analyzed cross-sectional data from 230 asymptomatic members of families with ADAD participating in the Dominantly Inherited Alzheimer Network (DIAN) study including 120 preclinical mutation carriers (MCs) and 110 asymptomatic non-carriers (NCs). Differences in BMI and their relation with cerebral amyloid load and episodic memory as a function of estimated years to symptom onset (EYO) were analyzed. Preclinical MCs showed significantly lower BMIs compared to NCs, starting 11.2 years before …

Alterations In Erythrocyte Fatty Acid Composition In Preclinical Alzheimer's Disease, Kathryn Goozee, Pratishtha Chatterjee, Ian James, Kaikai Shen, Hamid R. Sohrabi, Prita R. Ash, Preeti Dave, Bethany Ball, Candice Manyan, Kevin Taddei, Roger Chung, Manohar L. Garg, Ralph Martins

Research outputs 2014 to 2021

Brain and blood fatty acids (FA) are altered in Alzheimer’s disease and cognitively impaired individuals, however, FA alterations in the preclinical phase, prior to cognitive impairment have not been investigated previously. The current study therefore evaluated erythrocyte FA in cognitively normal elderly participants aged 65 – 90 years via trans-methylation followed by gas chromatography. The neocortical beta-amyloid load (NAL) measured via positron emission tomography (PET) using ligand ¹⁸F-Florbetaben, was employed to categorise participants as low NAL (standard uptake value ratio; SUVR < 1.35, N = 65) and high NAL or preclinical AD (SUVR ≥ 1.35, N = 35) wherein, linear models were employed to compare FA compositions between the two groups. Increased arachidonic acid (AA, p < 0.05) and decreased docosapentaenoic acid (DPA, p < 0.05) were observed in high NAL. To differentiate low from high NAL, the area under the curve (AUC) generated from a ‘base model’ comprising age, gender, APOEε4 and education (AUC = 0.794) was outperformed by base model + AA:DPA (AUC = 0.836). Our …

Acute Elevations In Serum Hormones Are Attenuated After Chronic Training With Traditional Isoinertial But Not Accentuated Eccentric Loads In Strength-Trained Men, Simon Walker, Keijo Häkkinen, Greg Haff, Anthony J. Blazevich, Robert Newton

Research outputs 2014 to 2021

It has been proposed that the maintenance of acute hormonal responses reveal an efficacy of a training stimulus to evoke ongoing increases in strength and muscle mass. We previously observed that maximum strength continued to improve throughout a 10‐week period in an accentuated eccentric loading group (AEL) but not a traditional isoinertial loading (ISO) group. Therefore, this study investigated whether the magnitude of acute hormonal responses was greater (i.e., maintained) in AEL compared to ISO at the end of the training period. Subjects in AEL (eccentric load = concentric load + 40%) and ISO performed experimental loading tests (three sets …

Superior Effects Of Eccentric To Concentric Knee Extensor Resistance Training On Physical Fitness, Insulin Sensitivity And Lipid Profiles Of Elderly Men, Trevor Chung-Ching Chen, Wei-Chin Tseng, Guan-Ling Huang, Hsin-Lian Chen, Kuo-Wei Tseng, Kazunori Nosaka

Research outputs 2014 to 2021

It has been reported that eccentric training of knee extensors is effective for improving blood insulin sensitivity and lipid profiles to a greater extent than concentric training in young women. However, it is not known whether this is also the case for elderly individuals. Thus, the present study tested the hypothesis that eccentric training of the knee extensors would improve physical function and health parameters (e.g., blood lipid profiles) of older adults better than concentric training. Healthy elderly men (60–76 years) were assigned to either eccentric training or concentric training group (n=13/group), and performed 30–60 eccentric or concentric …

Role Of Route Previewing Strategies On Climbing Fluency And Exploratory Movements, Ludovic Seifert, Romain Cordier, Dominic Orth, Yoan Courtine, James L. Croft

Research outputs 2014 to 2021

This study examined the role of route previewing strategies on climbing fluency and on exploratory movements of the limbs, in order to understand whether previewing helps people to perceive and to realize affordances. Eight inexperienced and ten experienced climbers previewed a 10 m high route of 5b difficulty on French scale, then climbed it with a top-rope as fluently as possible. Gaze behavior was collected from an eye tracking system during the preview and allowed us to determine the number of times they scanned the route, and which of four route previewing strategies (fragmentary, ascending, zigzagging, and sequence-of-blocks) they used. …

Prevention Of Downhill Walking-Induced Muscle Damage By Non-Damaging Downhill Walking, Sumiaki Maeo, Masayoshi Yamamoto, Hiroaki Kanehisa, Kazunori Nosaka

Research outputs 2014 to 2021

Purpose:

Mountain trekking involves level, uphill, and downhill walking (DW). Prolonged DW induces damage to leg muscles, reducing force generating ability and muscle coordination. These increase risks for more serious injuries and accidents in mountain trekking, thus a strategy to minimize muscle damage is warranted. It has been shown that low-intensity eccentric contractions confer protective effect on muscle damage induced by high-intensity eccentric contractions. This study tested the hypothesis that 5-min non-damaging DW would attenuate muscle damage induced by 40-min DW, but 5-min level walking (LW) would not.

Methods:

Untrained young men were allocated (n = 12/group) to either a …

Prediction Of Everyday Task Performance In Older Adults By Perceived Health, Self-Efficacy And Cognitive Ability, Edward Helmes, Joan Klinger

Research outputs 2014 to 2021

While research links neuropsychological performance to everyday functioning in cognitively impaired older adults, comparatively little research has investigated this relationship in unimpaired older people. This study investigated that relationship. A total of 134 independently living adults aged 60–93 years completed Cognistat, the Direct Assessment of Functional Status (DAFS), the Personality in Intellectual-Aging Contexts and a four-item subjective health measure. Hierarchical regression was used to examine the relative ability of these measures to predict the functional domains of the DAFS, hypothesizing that the health and self-efficacy measures would be more strongly associated with DAFS scores than with the cognitive domains. Self-reported …

“Looking Over The Backyard Fence”: Householders And Mosquito Control, Samir Mainali, Ram Sharan Lamichhane, Kim Clark, Shelley Beatty, Maria Fatouros, Peter Neville, Jacques Oosthuizen

Research outputs 2014 to 2021

Background:

Vector-borne diseases are a significant public health problem in Western Australia. Mosquitoes are responsible for the transmission of a number of pathogens and may pose a serious nuisance problem. Prevention efforts in the State are multi-faceted and include physical, chemical, and cultural control methods for restricting mosquito breeding. This is less complex where breeding areas are located within public open spaces. In Australia’s developed urban areas, breeding sites are, however, frequently located within private residential landholdings, where the scope of public health officials to act is constrained by law and practicality. Consequently, mosquito prevention in these locations is …

Research outputs 2014 to 2021

There is increasing interest in the phenomena of international student mobility and the growing global demand for skilled nurses. Little is known, however, about the learning experiences of Chinese nursing students at Australian universities. This study begins to address this gap. A narrative inquiry methodology was employed. In-depth interviews and focus group discussions, along with field notes and observations were conducted with six Chinese undergraduate nursing students studying undergraduate nursing in Western Australia. Chinese nursing students in Australia experienced fear and anxiety, driven by unfamiliarity with the hospital environment, education methods, and assessment expectations. Clinical placement experiences in Australian health …

The Manipulation Of Pace Within Endurance Sport, Sabrina Skorski, Chris Abbiss

Research outputs 2014 to 2021

In any athletic event, the ability to appropriately distribute energy is essential to prevent premature fatigue prior to the completion of the event. In sport science literature this is termed “pacing.” Within the past decade, research aiming to better understand the underlying mechanisms influencing the selection of an athlete’s pacing during exercise has dramatically increased. It is suggested that pacing is a combination of anticipation, knowledge of the end-point, prior experience and sensory feedback. In order to better understand the role each of these factors have in the regulation of pace, studies have often manipulated various conditions known to influence …

Family Group Conferencing—Its Added Value In Mental Health Care, Gert Schout, Ellen Meijer, Gideon De Jong

Research outputs 2014 to 2021

Worldwide, there is a growing emphasis on reducing coercion and involving social networks in the care of mental health clients. Nurses should encourage their clients to regain control over their lives, preferably with less coercion and with help from their social network. During four years, a Dutch evaluation study was deployed to determine the applicability of mobilising help from social networks of people with psychiatric problems. Specifically the potential of Family Group Conferencing was examined. In this discursive article the question, ‘what Family Group Conferencing adds to the existing methods that aim to reduce coercion in mental health care and …

A Mediterranean Diet To Improve Cardiovascular And Cognitive Health: Protocol For A Randomised Controlled Intervention Study, Alexandra T. Wade, Courtney R. Davis, Kathryn A. Dyer, Jonathan M. Hodgson, Richard J. Woodman, Hannah A.D. Keage, Karen J. Murphy

Research outputs 2014 to 2021

The Mediterranean diet has demonstrated efficacy for improving cardiovascular and cognitive health. However, a traditional Mediterranean diet delivers fewer serves of dairy and less dietary calcium than is currently recommended in Australia, which may limit long-term sustainability. The present study aims to evaluate whether a Mediterranean diet with adequate dairy and calcium can improve cardiovascular and cognitive function in an at-risk population, and thereby reduce risk of cardiovascular disease (CVD) and cognitive decline. A randomised, controlled, parallel, crossover design trial will compare a Mediterranean diet supplemented with dairy foods against a low-fat control diet. Forty participants with systolic blood pressure …

An Examination Of Students’ Perceptions Of Their Interprofessional Placements In Residential Aged Care, Karla L. Seaman, Rosemary Saunders, Elly Williams, Jane Harrup-Gregory, Helen Loffler, Fiona Lake

Research outputs 2014 to 2021

It is essential that health professionals are trained to provide optimal care for our ageing population. Key to this is a positive attitude to older adults along with the ability to work in teams and provide interprofessional care. There is limited evidence on the impact an interprofessional education (IPE) placement in a residential aged care facility (RACF) has on students. In 2015 in Western Australia, 51 students (30 % male, median age 23 years), from seven professions, undertook a placement between 2 and 13 weeks in length at 1 RACF. Pre- and post-placement measurements of attitudes to the elderly were …

Possible Role Of Common Spices As A Preventive And Therapeutic Agent For Alzheimer's Disease, Omid Mirmosayyeb, Amirpouya Tanhaei, Hamid R. Sohrabi, Ralph Martins, Mana Tanhaei, Mohammad Admin Najaf, Ali Safaei, Rokhsareh Meamar

Research outputs 2014 to 2021

For centuries, spices have been consumed as food additives or medicinal agents. However, there is increasing evidence indicating the plant-based foods in regular diet may lower the risk of neurodegenerative diseases including Alzheimer disease. Spices, as one of the most commonly used plant-based food additives may provide more than just flavors, but as agents that may prevent or even halt neurodegenerative processes associated with aging. In this article, we review the role and application of five commonly used dietary spices including saffron turmeric, pepper family, zingiber, and cinnamon. Besides suppressing inflammatory pathways, these spices may act as antioxidant and inhibit …

High Prevalence Of Toxigenic Clostridium Difficile In Public Space Lawns In Western Australia, Peter Moono, Su Chen Lim, Thomas V. Riley

Research outputs 2014 to 2021

Clostridium difficile is a well-established hospital pathogen. Recently, it has been detected increasingly in patients without hospital contact. Given this rise in community associated infections with C. difficile, we hypothesized that the environment could play an important role in transmission of spores outside the hospital. Lawn samples (311) collected in public spaces in the metropolitan area of Perth, Western Australia, from February to June 2016 were cultured for C. difficile. C. difficile was isolated from the samples by direct and enrichment culture, and characterized by standard molecular methods using toxin gene PCR and ribotyping. The overall prevalence of …

Research outputs 2014 to 2021

Long-chain polyunsaturated fatty acids like conjugated linoleic acids (CLA) are required for normal neural development and cognitive function and have been ascribed various beneficial functions. Recently, oral CLA also has been shown to increase testosterone (T) biosynthesis, which is known to diminish traumatic brain injury (TBI)-induced neuropathology and reduce deficits induced by stroke in adult rats. To test the impact of CLA on cognitive recovery following a TBI, 5–6 month old male Sprague Dawley rats received a focal injury (craniectomy + controlled cortical impact (CCI; n = 17)) or Sham injury (craniectomy alone; n = 12) and were injected with …

Research outputs 2014 to 2021

Clostridium difficile PCR ribotype (RT) 014 is well-established in both human and porcine populations in Australia, raising the possibility that C. difficile infection (CDI) may have a zoonotic or foodborne etiology. Here, whole genome sequencing and high-resolution core genome phylogenetics were performed on a contemporaneous collection of 40 Australian RT014 isolates of human and porcine origin. Phylogenies based on MLST (7 loci, STs 2, 13, and 49) and core orthologous genes (1260 loci) showed clustering of human and porcine strains indicative of very recent shared ancestry. Core genome single nucleotide variant (SNV) analysis found 42 % of human strains showed …

Do Muscle Strength Imbalances And Low Flexibility Levels Lead To Low Back Pain? A Brief Review, Cassio Victora Ruas, Adriane Vieira

Research outputs 2014 to 2021

Chronic low back pain (CLBP) has been related to hips, trunk and spine strength imbalances and/or low flexibility levels. However, it is not clear if the assessment and normalization of these variables are effective for prevention of low back pain (LBP) episodes and rehabilitation of patients with CLBP. This brief review explored studies that have associated hip, trunk and spine strength imbalances and/or low flexibility levels to LBP episodes or CLBP condition. Fourteen studies were selected by accessing PubMed and Google Scholar databases. Collectively, the selected studies demonstrate that trunk eccentric/concentric and flexion/extension strength imbalances may be associated with CLBP …

Current Research And Statistical Practices In Sport Science And A Need For Change, Jake R. Bernards, Kimitake Sato, G. Gregory Haff, Caleb D. Bazyler

Research outputs 2014 to 2021

Current research ideologies in sport science allow for the possibility of investigators producing statistically significant results to help fit the outcome into a predetermined theory. Additionally, under the current Neyman-Pearson statistical structure, some argue that null hypothesis significant testing (NHST) under the frequentist approach is flawed, regardless. For example, a p-value is unable to measure the probability that the studied hypothesis is true, unable to measure the size of an effect or the importance of a result, and unable to provide a good measure of evidence regarding a model or hypothesis. Many of these downfalls are key questions researchers strive …
