ABSTRACT
Objective: The aim of this study was to examine the effect of hyper pronated foot on postural control and ankle muscle activity during running and cutting movement (v-cut).Methods: In this Cross-Sectional study, 42 young physically active (exercising three times per week regularly) males participated in this study, including 21 with hyper-pronated feet and 21 with normal feet. Each participant completed a running and cutting task. Body postural control was measured using a force platform (1000Hz) which was synchronized with surface electromyography of selected ankle muscles. MATLAB software was used to process and analyze the data. One-away ANOVA was used to identify any differences between groups.Results: Differing muscle activation patterns in the surrounding ankle musculature (tibialis anterior, peroneus longus) through to reduced postural stability in the medial-lateral direction and increased vertical ground reaction forces were observed between groups.Conclusion: According to the obtained results it seems that subtalar hyper-pronation can be regarded as a factor affecting the biomechanics of cutting by changing activation patterns of the muscles surrounding the ankle, and reducing postural control of the body in medial-lateral direction, but not in anterior-posterior direction.

Objetivo: El objetivo de este estudio fue examinar el efecto del pie hiperpronado sobre el control postural y la actividad de los músculos del tobillo durante el movimiento de carrera y cambio de dirección.Métodos: En este estudio transversal, participaron 42 hombres jóvenes físicamente activos (ejercitándose tres veces por semana con regularidad), incluidos 21 con pies hiperpronados y 21 con pies normales. Cada participante completó una tarea de correr y cambiar de dirección. El control de la postura corporal se midió utilizando una plataforma de fuerza (1000 Hz) que se sincronizó con la electromiografía de superficie de los músculos seleccionados del tobillo. Se utilizó el software MATLAB para procesar y analizar los datos. Se utilizó un ANOVA de una distancia para identificar las diferencias entre los grupos.Resultados: Se observaron diferentes patrones de activación muscular en la musculatura del tobillo (tibial anterior, peroneo largo) con estabilidad postural reducida en la dirección medial-lateral y un aumento de las fuerzas de reacción vertical del suelo entre los grupos.Conclusión: De acuerdo con los resultados obtenidos, parece que la hiperpronación puede ser considerada como un factor que afecta la biomecánica del cambio de dirección al modificar los patrones de activación de los músculos que del tobillo y reducir el control postural del cuerpo en dirección medial-lateral, pero no en dirección anteroposterior.

Objetivo: O objetivo deste estudo é examinar o efeito do pé hiper-pronado no controlo postural e actividade muscular no tornozelo durante a corrida e movimentos cortantes.Métodos: Neste estudo seccionado, 42 rapazes fisicamente ativos (exercitam regularmente 3 vezes por semana) participaram neste estudo, incluindo 21 com pé hyper-pronated. Cada participante completou um desafio de corrida e corte. A postural corporal foi medida usando uma plataforma com potência de 1000Hz, cujo fora sincronizada com uma eletromiografia superficial do músculos do tornozelo seleccionados. O software MATLAB foi utilizado para processar e analisar os dados. ANOVA foi utilizado para identificar quaisquer diferenciações entre grupos.Resultados: Padrões divergentes de ativação por volta do músculo do tornozelo (tibialis anterior peroneus longus) pela redução de estabilidade postural na direção medial-lateral e foi observado um aumento de reacções verticais térreas entre grupos.Conclusão: De acordo com os resultados obtidos, parece que a hyper-pronation pode ser observada como um factor que afecta os biomecânica de corte através da mudança e ativação dos padrões dos músculos à volta do tornozelo, reduzindo assim o controlo do corpo na direção médio-lateral mas não na direção anterior-posterior.

INTRODUCTION: Controlled trials support the efficacy of exercise as a treatment modality for chronic conditions, yet effectiveness of real-world Exercise Physiology services is yet to be determined. This study will investigate the efficacy and cost-effectiveness of services provided by Accredited Exercise Physiologists (AEPs) for clients with type 2 diabetes (T2D) in clinical practice. METHODS AND ANALYSIS: A non-randomised, opportunistic control, longitudinal design trial will be conducted at ten Exercise Physiology Clinics. Participants will be individuals with T2D attending one of the Exercise Physiology Clinics for routine AEP services (exercise prescription and counselling) (intervention) or individuals with T2D not receiving AEP services (usual care) (control). The experimental period will be 6 months with measurements performed at baseline and at 6 months. Primary outcome measures will be glycosylated haemoglobin (HbA1c), resting brachial blood pressure (BP), body mass index, waist circumference, 6 min walk test, grip strength, 30 s sit to stand, Medical Outcomes Short-Form 36-Item Health Survey and Active Australia Questionnaire. Secondary outcomes will be medication usage, out-of-pocket expenses, incidental, billable and non-billable health professional encounters and work missed through ill health. Healthcare utilisation will be measured for 12 months prior to, during and 12 months after trial participation using linked data from Medicare Benefits Schedule and Pharmaceutical Benefits Scheme data. ETHICS AND DISSEMINATION: The study is a multicentre trial comprising: University of Tasmania, University of New South Wales Lifestyle Clinic, University of Canberra, Baker Heart and Diabetes Institute (covered under the ethics approval of University of Tasmania Health and Medical Ethics Committee H0015266), Deakin University (Approval number: 2016-187), Australian Catholic University (2016-304R), Queensland University of Technology (1600000049), University of South Australia (0000035306), University of Western Australia (RA/4/1/8282) and Canberra Hospital (ETH.8.17.170). The findings of this clinical trial will be communicated via peer-reviewed journal articles, conference presentations, social media and broadcast media. TRIAL REGISTRATION NUMBER: ACTRN12616000264482.

Nurses, midwives, and paramedics are exposed to high degrees of job demand, which impacts health status and job satisfaction. The aim of this study was to explore the experiences and perceptions of health with a group of nurses, midwives and paramedics in Australia. Specifically, this paper reveals the findings related to the dataset on physical health. In this regard, the researchers sought to explore the relationship between physical health and job satisfaction, and the relationship between health status and stress levels. The study adopted a mixed methodology and used two methods for data collection: one-on-one interviews exploring the relationship between physical health and job satisfaction, and a survey questionnaire focusing on self-rated stress management. The individual interviews were conducted for further exploration of the participants' responses to the survey. There were 24 health care participants who were drawn from metropolitan and regional Australia. The findings revealed participants: had a desire to increase their physical activity levels; had different perspectives of physical health from those recommended by government guidelines; and viewed physical health as important to job satisfaction, yet related to stress and fatigue.
