Faculty of Health and Behavioural Sciences - Papers (Archive)

Background: Knowing the total energy expenditure (TEE) of overweight adults is important for prescribing weight loss interventions. However, objective measurements of TEE may not always be readily available and can be expensive. This study aimed to investigate the validity of RT3 accelerometers in predicting the TEE of sedentary overweight adults, and to identify any sensitivity to anthropometric changes. Methods: The analysis used data from a 12-week weight loss study. At baseline and 12-week, TEE was predicted using RT3 accelerometers during whole room calorimeter stays. Bias between 2 methods was compared at and between the baseline and 12-week measurement points. Multiple …

Relationship Between Plantar Pressures, Physical Activity And Sedentariness Among Preschool Children, Karen J. Mickle, Dylan P. Cliff, Bridget J. Munro, Anthony D. Okely, Julie R. Steele

Faculty of Health and Behavioural Sciences - Papers (Archive)

It has been speculated that high plantar pressures might cause foot pain and discomfort which, in turn, may discourage children from being physically active and result in them spending more time in sedentary activities. The purpose of this study was to determine whether plantar pressure distributions generated by preschool children were correlated with objectively measured time spent in physical activity and sedentary behaviour. Dynamic plantar pressures were measured for 33 preschool children (age = 4.3±0.6 years; height = 1.06±0.1 m; mass = 18.4±2.9 kg; 17 boys) as they walked across an emed AT-4 pressure platform. Physical activity was objectively assessed …

Cerebral amyloid-β (Aβ) deposition is a critical feature of Alzheimer’s disease. Aβ is derived from the amyloid-β protein precursor (AβPP) via two sequential cleavages that are mediated by β-secretase and the γ-secretase complex. Such amyloidogenic AβPP processing occurs in lipid raft microdomains of cell membranes and it is thought that modulating the distribution of lipids in rafts may regulate AβPP processing and Aβ production. Certain ATP-binding cassette (ABC) transporters regulate lipid transport across cell membranes and, as recent studies reveal, within membrane microdomains. ABCA1 also regulates Aβ metabolism in the brain although its direct impact on AβPP remains an open …

Methods/Design This study protocol describes the design of a 3-year cluster randomised controlled trial (CRCT), in which schools are the clusters. The study consists of a 13-week intervention and 1 week each of pre-and post-testing. We are recruiting 12 schools …

Association Between Physical Activity And Motor Skills And Coordination In Portuguese Children, Luis Lopes, Vitor Pires Lopes, Rute Santos, Beatriz Pereira

Faculty of Social Sciences - Papers (Archive)

Nowadays, there is growing evidence in literature that Health benefits from regular physical activity (PA). The variance in PA among children is caused by a number of factors including their motor abilities and coordination. The aim of the study was to analyse the relation between usual PA and gross motor abilities and motor coordination in children aged 6 to 7 years. The sample comprised 21 children, aged in average 6,38±0,50 years. Physical activity was accessed by accelerometry, gross motor abilities by using the Test of Gross Motor Development (TGMD-2) and motor coordination by using the Körperkoordination Test für Kinder (KTK). …

Faculty of Social Sciences - Papers (Archive)

Background: In the past years, there has been a growing concern in designing physical activity (PA) programmes for elderly people, because evidence suggests that such health promotion interventions may reduce the deleterious effects of the ageing process. Quality is an important issue when designing a PA programme for older people. Some studies support the Excellence Model of the European Foundation for Quality Management (EFQM) as an operational framework for evaluating the quality of an organization. Within this context, the aim of this study was to characterize the quality management models of the PA programmes developed by Portuguese Local Administration to …

Evaluation Of Physical Activity Programmes For The Elderly - Exploring The Lessons From Other Sectors And Examining The General Characteristics Of The Programmes, Ana I. Marques, Pedro Soares, Luisa Soares-Miranda, Carla Moreira, Antonio Oliveira-Tavares, Paula Clara-Santos, Susana Vale, Rute Santos, Joana Carvalho

Faculty of Social Sciences - Papers (Archive)

Background

In Portugal, there are several physical activity (PA) programmes for elderly people developed by the local government. The importance of these programmes has been increasing since the evidence has shown that this type of health promotion interventions may reduce the deleterious effects of the ageing process. However, no study has already identified the general characteristics of these programmes nor if they use any scheme to assess the quality of the service provided. A widely-used scheme is the EFQM Excellence Model, which will be in the core of our present work. Thus, the main aims of this preliminary study were …

A Proposed Adaptation Of The European Foundation For Quality Management Excellence Model To Physical Activity Programmes For The Elderly - Development Of A Quality Self-Assessment Tool Using A Modified Delphi Process, Ana I. Marques, Leonel Santos, Pedro Soares, Rute Santos, Antonio Oliveira-Tavares, Jorge Mota, Joana Carvalho

Faculty of Social Sciences - Papers (Archive)

Background There has been a growing concern in designing physical activity (PA) programmes for elderly people, since evidence suggests that such health promotion interventions may reduce the deleterious effects of the ageing process. Complete programme evaluations are a necessary prerequisite to continuous quality improvements. Being able to refine, adapt and create tools that are suited to the realities and contexts of PA programmes for the elderly in order to support its continuous improvement is, therefore, crucial. Thus, the aim of this study was to develop a self-assessment tool for PA programmes for the elderly. Methods A 3-round Delphi process was …
